Recently, I’ve been toying with ChatGPT, the brainchild of OpenAI. You’re wondering why? Well, I’m a bit of a technomad, a web developer, and an SEO wizard with a decade-long track record. My job, my passion, is to whip up quality content that stands out in the endless sea of web pages.
Imagine ChatGPT as a chef in a vast kitchen. Its job? Cooking up delicious sentences for you. Now, let’s meet our star ingredients:
Why should a plumber, electrician, or roofer care about this techy stuff? Simple: Time is money. Understanding even the basics of these settings helps you get *better* first drafts for your website content, emails, or even social media posts from AI tools like ChatGPT. Less editing time = more time on the job or quoting. This isn’t about becoming an AI expert; it’s about using the tool smarter to save yourself hassle.
Section 1: Top_P – The Creativity Dial
- Low (e.g., 0.1): Stays focused, predictable, good for factual stuff.
- High (e.g., 0.9): More random, creative, good for brainstorming or varied phrasing.
- Nolan’s Go-To (often): Around 0.5 for a balance of coherence and fresh ideas.
Higher values mean more creativity.
Think of this as the chef’s adventurousness. Low Top_P (like 0.1) means the chef sticks to tried-and-true recipes. High Top_P (say 0.9)? The chef goes wild, throwing in unexpected spices!
Example:
- Low Top_P: “The cat sat on the mat.”
- High Top_P: “The feline perched atop the decorative floor covering.”
Section 2: Frequency Penalty – The Repetition Police
- Low (e.g., 0.0): Lets the AI repeat the same word often if it fits.
- High (e.g., 1.0+): Strongly discourages repeating the exact same word frequently.
- Nolan’s Go-To (often): Around 0.7 to keep the language fresh without sounding forced.
Higher values mean fewer repeated words.
This is like a “repeat police” in the kitchen. It stops the chef from using the same ingredient too often. Higher values mean stricter policing.
Example:
- Low penalty: “The big dog saw the big cat and made a big noise.”
- High penalty: “The large canine spotted the hefty feline and created a thunderous racket.”
Section 3: Presence Penalty – The Topic Variety Nudge
- Low (e.g., 0.0): Lets the AI stick to closely related concepts/words.
- High (e.g., 1.0+): Encourages the AI to introduce *new concepts* or words, even if used just once before.
- Nolan’s Go-To (often): Around 0.7 for broader topic coverage without rambling.
Higher values mean more unique words.
Think of this as a “variety encourager.” It nudges the chef to open different spice jars, not just the ones right in front. Higher values mean more variety.
Example:
- Low penalty: “The good movie had a good plot and good actors.”
- High penalty: “The excellent film boasted an intriguing storyline and talented performers.”
Now, here’s the kicker: these ingredients work together! Like salt and pepper, they balance each other out. Too much variety (high Presence Penalty) might make things weird, while too little (low Frequency Penalty) could make things boring.
Exploring how to adjust settings in ChatGPT can significantly enhance the quality of the text it generates, making it more creative and coherent. Here’s how we do it:
- Top P at 0.5: This setting balances the diversity of the responses. Lower settings result in less varied text, while higher settings increase randomness.
- Frequency and Presence Penalties at 0.7: These help in avoiding too much repetition of words and ideas, keeping the conversation fresh.
We also apply different techniques when crafting questions for ChatGPT:
- Chain of Thought: We prompt the model to think through a problem step by step before answering.
- Step-by-Step: This involves breaking down the answer into clearly defined stages.
These adjustments and strategies are part of what’s called ‘prompt engineering,’ a method to improve how AI understands and responds to questions. For those interested, diving deeper into prompt engineering can offer valuable insights into achieving better outcomes from AI text generation.
TL;DR?
Watch this blog here if you’re short on time.
In my latest escapades with ChatGPT, I’ve stumbled upon the sacred art of parameter tuning, the real MVP when it comes to crafting high-caliber text. It’s like adjusting the knobs on a cosmic radio to tune into the right channel. I found that when you set Top P to a solid 0.5, and give a gentle nudge to Frequency Penalty and Presence Penalty, say around 0.7, you’ve hit the sweet spot. I’m almost always on temp 0.1 because consistency is key, but it depends on the app; it’s just as much an art as a science
This potent combo gives rise to text that is as diverse as a tropical rainforest and as creative as a jazz improv, but without spiraling into utter nonsense. It’s the golden mean, my friend, where relevance shakes hands with coherence
In this devlog, I’ll share my experience with ChatGPT and these specific parameters, and provide tips and best practices for other developers and content creators looking to improve their text generation capabilities. Let’s dive in!
Section 1 Deep Dive: Top_P – The Creativity Dial in Action
In this section, we’ll examine the impact of the top_p parameter in GPT-3 on the output text diversity, while keeping the temperature constant at 0.5. To demonstrate this, we’ve generated text samples using three different top_p values: 0, 0.5, and 1. In the table below, you can see the generated text samples
| Top_P | Sample 1 | Sample 2 | Sample 3 |

Digging Deeper: How Top_P Actually Works
Stepping into the pulsating core of our technomad journey, we’re gonna unwrap the juicy secrets behind how our trusty sidekick, ChatGPT, churns out its magic. When you’ve got the top_p tuned to a cold, rigid zero, our buddy ChatGPT goes full auto-pilot mode, spewing out identical outputs across all samples. It’s like a monotonous DJ, dishing out the most probable beats at every step, leading to a repetitive playlist lacking diversity
Bump up that top_p to a breezy 0.5, and voila! Our AI buddy starts to mix things up. Each output’s a unique groove, painting a distinct, vacation-worthy picture. It’s like a jukebox that’s had a sip of creativity juice, pulling from a broader palette of tokens, conjuring up a diverse cocktail of outputs
Crank that top_p all the way up to a blazing 1, and our ChatGPT friend goes full ‘freestyle’, sampling from its entire token smorgasbord. The resulting outputs are a wild mix, but hey, they’re still coherent and on point, only more varied than the staid outputs at lower top_p values. Though, keep an eye out when you max out those tokens; you don’t want the narrative ship to veer off course!
Top_p, my friend, is like your AI DJ’s creative dial. Lower values churn out more focused, predictable outputs, while cranking it up brings in a medley of more varied, creative tunes. Need to whip up some artsy, out-of-the-box content? Turn that top_p up to a cool 0.5 or 1, and let ChatGPT unfurl its imaginative wings. But if you’re gunning for a professional tone, keep that top_p low, maybe at a sensible 0.3, or even closer to 0, ensuring you get focused, coherent, and dependable outputs.
ELI5: Top_P
👶 Okay, let’s break this down real simple:
When ChatGPT talks, it picks from a huge pile of words. Top_P is like a rule that tells ChatGPT how many words it can look at before it picks one to use.
Here’s how it works, step by step, like you’re picking a treat from a huge bag:
- You ask ChatGPT something. This is like reaching into the bag for a treat.
- ChatGPT looks at the treats. Instead of looking at all the treats in the bag, Top_P tells it to only look at the best ones at the top.
- Top_P decides how many treats to look at.
- If Top_P is big: ChatGPT can look at lots of treats and pick a really special one.
- If Top_P is small: ChatGPT only looks at a few treats and picks one of the usual ones.
So, Top_P helps ChatGPT decide if it’s going to say something usual or something more surprising and creative. It’s like choosing between grabbing the first treat you touch or looking for the best treat in the bag.
Why is it called Top_P
Top_P has got its name as it points to the proportion, or the ‘P’ of the highest likelihood tokens considered during the spellcasting, err, text generation process. The ‘Top’ part signifies that ChatGPT is picking out the top probability tokens based on their likelihood of being the next token in the sequence, and the ‘P’ denotes the slice of these tokens involved in the process
In short, Top P 1.0 is like saying to ChatGPT, “Go on, use all tokens in the vocabulary.”
Recent Advancements and Applications
In 2024, OpenAI introduced GPT-4o, a significant leap in AI technology with its advanced vision capabilities. GPT-4o can analyze and generate text based on images and screenshots, making it a versatile tool for applications that require detailed visual descriptions. For instance, Microsoft’s new accessibility tools leverage GPT-4o to provide rich descriptions of images and videos, enhancing inclusivity for visually impaired users. This shows how AI is not just about text anymore—it’s about a holistic interaction with our digital world (The Official Microsoft Blog).
Section 2 Deep Dive: Frequency Penalty – The Repetition Police at Work
While tinkering with ChatGPT, I’ve also played around with the Frequency Penalty parameter. By tweaking this value, you can control how much of a repeat offender your generated text is going to be. Let’s dig into this, shall we?
To demonstrate this, let’s examine the results of a simple prompt:
Model: gpt-3.5-turbo-0613
Prompt: Product Description for a cotton t-shirtwith a temperature of 0, max-tokens at 256 and Top P set to 0, while adjusting the Frequency Penalty
| Frequency Penalty | Example | Word Frequencies |
|---|---|---|

Vocabulary variation and frequency penalties, oh my! The difference between a frequency penalty of 2 and 1, in this case, is about as significant as a molehill next to a mountain – it’s not. With just two extra unique words popping up in the higher penalty example, and a smidgen of repetition in both, it’s clear that a game-changer it is not.
Now, let’s add a frequency penalty of 0 into the mix. What do we get? Fewer unique words (36, to be exact) compared to its higher-penalty cousins, and slightly less repetition, with only four repeated words. You’d expect a dramatic difference, but the impact of frequency penalty on vocabulary variation, in this context, is as compelling as a potato at a fruit party
ELI5: Frequency Penalty
👶 Okay, let’s break this down real simple:
The Frequency Penalty is a setting used when ChatGPT is creating its responses. Imagine ChatGPT has a deck of cards, where every card has a word on it. When it’s ChatGPT’s turn to speak, it plays a card to add a word to the conversation.
still not getting it
Absolutely, let’s dive into the concept of Frequency Penalty with a straightforward approach:
- Imagine ChatGPT as a kid in a candy store, where the candies are words.
- Frequency Penalty is like a little reminder for the kid.
- Without the reminder: The kid might grab the same candy (word) too many times because it’s their favorite.
- With the reminder: The kid remembers to try different candies (words), not just their favorite one over and over.
- How the Frequency Penalty reminder works:
- Each candy (word) starts with a full ‘yumminess’ score. The kid wants the yummiest candies.
- Each time the kid takes a candy (uses a word), that candy becomes a little less yummy (less desirable).
- Candies (words) that become less yummy get picked less. The kid looks for other yummy candies instead.
- Adjusting the reminder changes the kid’s choices:
- A strong reminder (high Frequency Penalty): The kid is really encouraged to try all different candies, not just the favorites. After taking one, it quickly becomes less appealing.
- A gentle reminder (low Frequency Penalty): The kid can still take their favorite candies, but they’re just a little less yummy each time, so they might still come back to them sometimes.
- Why use the Frequency Penalty?
- To keep the conversation interesting. Just like trying different candies makes the visit to the store more fun, using a variety of words makes ChatGPT’s responses more engaging.
- To avoid sounding repetitive. It helps ChatGPT avoid saying the same thing the same way too many times, which can get boring.
The Frequency Penalty is like a subtle nudge to keep exploring new words and not just stick to what’s been said before, making sure every ‘candy’ gets a chance to shine in the conversation.

Section 3 Deep Dive: Presence Penalty – The Topic Variety Nudge Explained
So, we’ve dealt with frequency penalties. Now let’s wade into the waters of presence penalties
| Presence Penalty | Example | Word Frequencies |
|---|---|---|
| 0 | Introducing our premium cotton t-shirt, the perfect blend of comfort, style, and durability. Crafted with the finest quality cotton fabric, this t-shirt is designed to provide a soft and breathable feel against your skin | cotton:2, tshirt:2, the:2, and:2, introducing:1, our:1, premium:1, perfect:1, blend:1, of:1, comfort:1, style:1, durability:1, crafted:1, with:1, finest:1, quality:1, fabric:1, this:1, is:1, designed:1, to:1, provide:1, a:1, soft:1, breathable:1, feel:1, against:1, your:1, skin:1 |

Like the yin to frequency penalty’s yang, the presence penalty controls the likelihood of selecting tokens that have already made their debut in the generated text. Frequency penalty, on the other hand, plays gatekeeper to high-frequency tokens during text generation
It looks like it has more effect on function words like ‘the, and’:
ELI5: Presence Penalty
👶 Okay, let’s break this down real simple:
Okay, think of it like when you’re playing a game of tag. In this game, once you’ve been “it,” you get a little tired each time you’re tagged again. If you’re really tired, you’re less likely to be “it” again because you’re running slower. The Presence Penalty in ChatGPT works a bit like that. It’s a rule that makes the AI less likely to use the same words over and over again. So, if a word has been “it” (used even once), the AI tries to tag a new word next time, keeping the conversation full of different words.
still not getting it
Okay, let’s break it down super simple, step by step:
- ChatGPT is like a toy box full of words. It can reach in and pick any word to use when it talks to you.
- The Presence Penalty is like a rule for picking words.
- Without the rule: ChatGPT might keep picking the same favorite words over and over, which can be boring.
- With the rule: ChatGPT tries to pick different words it hasn’t used much yet (or at all), to make the conversation more interesting.
- How the Presence Penalty rule works:
- Every word has points. When ChatGPT talks, it uses words with the most points.
- If a word is used *at all*, it loses points (gets penalized). This penalty applies the first time it’s used and maybe again if used later, depending on settings, but the key is it penalizes based on *presence*, not *frequency*.
- Words with fewer points get less chance to be picked. So, ChatGPT looks for other words with more points – words it hasn’t used as much (or at all).
- What happens when we change the rule:
- If we make the rule strict (high Presence Penalty): ChatGPT avoids repeating words/topics even more strongly. It really wants to introduce new stuff.
- If we make the rule lenient (low Presence Penalty): ChatGPT is more okay with revisiting words/topics it has already mentioned.
- Why use the Presence Penalty?
- To make ChatGPT sound less repetitive on a topic level. It helps prevent circling back to the same ideas too quickly.
- To keep the conversation fresh and exploratory. It encourages ChatGPT to bring up new angles or related concepts.
So, the Presence Penalty helps ChatGPT to not sound like a broken record stuck on one idea. It encourages variety and keeps the chat lively!

As you can see, ChatGPT is not some monotonous machine, spewing out the same gibberish. No siree! Tweak its parameters, and you’ll see a world of difference in the quality and diversity of its outputs. It’s like a jukebox with infinite songs. With the right mix of Top P, Frequency Penalty, and Presence Penalty, you can make ChatGPT hum to your specific tune
But remember, this ain’t no substitute for good ol’ human-generated content. It’s a tool, a sidekick, to help you create. You’re the boss. Your judgement and expertise are what will ensure the content is accurate, enlightening, and useful for your audience
Section 4.5: Beyond the Basics – More GPT Knobs to Turn
When fine-tuning GPT models, there are several lesser-known parameters that give you more control over how responses are generated. Whether you’re optimizing output for creative writing, chatbots, or data-driven tasks, these parameters let you shape GPT’s behavior to meet specific needs. Here’s how they work.
Logit Bias
What it does: Logit Bias allows you to push the model toward or away from specific words or phrases. It’s like setting preferences for what you do or don’t want in the response.
Example: If you’re writing brand-friendly content, you can decrease the likelihood of negative words appearing and promote positive, on-brand language. Similarly, in content moderation, Logit Bias can reduce the chances of generating offensive language.
Stop Sequences
What it does: This tells the model where to stop. You define specific words or patterns that signal the end of a response, ensuring GPT doesn’t keep rambling.
Example: When generating lists or short summaries, you can set a stop sequence after a certain point (e.g., “5.”) to prevent the model from going beyond what you need.
N-Value (n)
What it does: N determines how many responses GPT generates for a single prompt. The higher the value, the more completion options you get.
Example: In brainstorming sessions or creative writing, setting n=3 generates three different outputs, giving you more choices to work with. Perfect for when you want variation and creativity without tweaking the prompt multiple times.
Tool Choice
What it does: Previously known as function_call, this parameter tells GPT when to call an external tool or function instead of generating text on its own.
Example: Imagine a chatbot integrated with a weather API. With Tool Choice, the model can either generate a text response or pull real-time weather data to answer a user’s question.
Stream
What it does: Enables real-time responses by sending the output token by token, instead of waiting for the entire completion.
Example: This is crucial for live chat applications where users expect immediate interaction. As GPT generates the response, it streams it in real-time, improving user engagement and reducing wait times.
Response Format
What it does: This controls how GPT delivers its output. You can specify if you want the result in plain text, JSON, or other formats, depending on how you plan to use the output.
Example: For applications that need to parse data, such as a dashboard that processes GPT’s responses, using JSON as the response format ensures the text can be easily processed and integrated into other systems.
Groq, Claude, and AIStudio Consoles
Compatibility: These platforms are fully compatible with GPT parameters, offering unique advantages for different use cases. Groq excels in speed, making it perfect for low-latency applications. Claude focuses on generating natural dialogue, ideal for customer service or conversational agents. AIStudio stands out for its accessibility, allowing developers to quickly scale AI models without heavy infrastructure.
Conclusion
These extra GPT parameters—Logit Bias, Stop Sequences, N-Value, Tool Choice, Stream, and Response Format—give you the tools to optimize GPT outputs for your specific needs. Whether you’re looking to control response length, generate multiple variations, or integrate external data, these parameters let you fine-tune GPT for better, more targeted results.
Quick Tips: Getting Better Results from GPT-4o Right Now
Top P (Nucleus Sampling): Think of Top_P as the creative dial for GPT-4o. Adjusting this parameter can dramatically change the output’s diversity. A Top_P value of 0.5 strikes a balance, allowing the model to consider a wider range of potential responses, thus fostering creativity and preventing repetitive outputs. This is ideal for tasks requiring varied and imaginative content.
Frequency and Presence Penalties: Set Frequency Penalty and Presence Penalty to around 0.7 to keep your text fresh and engaging. These settings discourage the model from repeating the same words or phrases, ensuring a more dynamic and interesting output. By fine-tuning these parameters, you can guide GPT-4o to produce content that is both coherent and diverse.
Advanced Prompt Techniques: Utilize advanced prompting techniques such as ‘Chain of Thought’, ‘Tree Thinking’, and ‘Step-by-Step’. These methods help structure the model’s responses, leading to more logical and detailed outputs. By guiding GPT-4o through a sequence of logical steps, you can achieve clearer and more comprehensive results.

We’re about to scratch the surface of an unexplored universe. Fasten your seatbelts; this exploration will be anything but shallow
Use ChatGPT? Want to learn how to make an online business with ChatGPT, work while traveling, and network with other nomads?
Consider ‘Chain of Thought’ prompts for a moment. They’re like the pied pipers, leading ChatGPT into a harmonious exchange, allowing it to weave threads of logic from previous statements and maintain a seamless dialogue. Then you’ve got the ‘Tree Thinking’ prompts, the architects of thought. They advocate a systematic, tree-branching approach to problem-solving
‘Step-by-Step’ prompts, they’re the tour guides. Ideal for navigating ChatGPT through labyrinthine tasks, laying out every step of the process, rather than just showcasing the finale. ‘Compression Prompts’, on the other hand, are the shrink rays, condensing elaborate directives into concise, token-friendly nuggets.
Commands such as “Err on the side of too much information”, they’re the whistleblowers. They prompt ChatGPT to spill all its beans on a topic. Meanwhile, “then do X” prompts are the choreographers. They sequence ChatGPT’s actions as if it were rehearsing for a well-coordinated performance
There’s a whole spectrum of prompts at play – scenario prompts, character prompts, point-of-view prompts. Each shapes ChatGPT, molding its responses to different situations, personifying it, or enabling it to adopt diverse perspectives.

tl;dr:
ChatGPT is one helluva weapon in your text generation arsenal. By mastering techniques like Top P, Frequency Penalty, and Presence Penalty, you control the unpredictability and diversity of generated text, avoiding repetition, and mundane content
Here’s a summary of the benefits of each technique:
- Top_P: The maestro of creativity and coherence, it lets you dictate how much the model stays on script or goes off on a tangent
- Frequency Penalty: The muse encouraging the model to find diverse ways of expressing an idea, upping the overall quality and variety of the output
- Presence Penalty: The bouncer that keeps a check on overuse or repetition of specific words or phrases, coaxing the model to spin more varied and engaging responses

Quick Answers: Your GPT Parameter FAQs
FAQ: What’s the Frequency Penalty Setting?
Frequency penalty is a parameter that allows you to control the repetition of words or phrases in ChatGPT’s responses. By increasing the frequency penalty value (e.g., 0.5 or above), you discourage the model from generating the same words multiple times, resulting in a more varied and engaging output.
FAQ: What’s the Presence Penalty Setting?
Presence penalty is a parameter used to encourage the model to include a diverse range of tokens (words/concepts) in the generated text. It penalizes a token simply for appearing *at all* in the text so far, making the AI more likely to talk about something new.
FAQ: Presence Penalty in GPT-3?
Presence penalty in GPT-3 works the same way as generally described for OpenAI models. You adjust its value (typically 0 to 2) to influence the introduction of new topics/words versus sticking to existing ones.
FAQ: Frequency vs. Presence Penalty – What’s the Diff?
Think of it like this:
Frequency Penalty: Punishes words based on *how many times* they’ve already appeared. Higher penalty = less likely to use a word for the 3rd, 4th, 5th time.
Presence Penalty: Punishes words just for *being present at all* (even once). Higher penalty = less likely to use a word again if it’s already been mentioned, encouraging new topics.
FAQ: What’s the frequency penalty in ChatGPT again?
It’s a dial (-2.0 to 2.0) to control how much ChatGPT avoids *repeating the same word often*. Higher value = less repetition of frequent words.
FAQ: What is the ChatGPT ‘penalty’?
Usually refers to either the Frequency Penalty (discourages *high frequency* repeats) or Presence Penalty (discourages *any* repeat, encourages new topics). Both aim for less repetitive text.
FAQ: How does the frequency penalty work in OpenAI API?
It adjusts the likelihood of picking a token based on how often it’s already appeared in the generated text. Positive values decrease the chance of repeating common words, negative values increase it (rarely used).
FAQ: What’s the frequency penalty in AI core?
It’s a common mechanism in language models to improve text quality by reducing monotonous word repetition. It modifies the probability distribution over the vocabulary during text generation.
FAQ: How do I set ChatGPT temperature?
Temperature (0 to 2) controls randomness. Lower values (e.g., 0.2) make output more focused and deterministic. Higher values (e.g., 0.8+) increase randomness and creativity. You adjust it alongside Top_P.
FAQ: What’s the presence penalty in OpenAI?
A parameter (-2.0 to 2.0) that penalizes tokens just for having appeared *at least once* in the text so far. Positive values encourage introducing new topics/words.
FAQ: How’s the frequency penalty used in GPT-3?
Same as described above – it ranges from -2.0 to 2.0 and helps manage the repetition of frequently used words within the generated output.
FAQ: Can you use OpenAI API without paying?
Yes, OpenAI often provides a free trial credit for new accounts. Models like GPT-4o also have free tiers with usage limits accessible via API, but sustained or high-volume use requires a paid plan.
FAQ: What are the limits of the ChatGPT API?
Limits vary by model and your account tier (usage history influences this). They are defined in Requests Per Minute (RPM) and Tokens Per Minute (TPM). Free/new tiers start lower (e.g., 60 RPM) and increase significantly for paid tiers (e.g., 3,500+ RPM for GPT-3.5-Turbo). Check the OpenAI rate limits documentation for specifics.
FAQ: What exactly is the frequency penalty?
It’s a numerical value applied during generation that decreases the probability of selecting a token proportionally to how many times that token has already appeared in the sequence being generated.
FAQ: Does ChatGPT store my data?
Via the consumer ChatGPT interface: Yes, conversations are used for training unless you opt out or use Temporary Chat. Via the API: OpenAI retains API data for 30 days for monitoring abuse, but does *not* use it for training their models by default (as of recent policy changes).
FAQ: How can I train ChatGPT on my data?
You don’t directly “train” the base ChatGPT model. You use OpenAI’s *Fine-Tuning API*. This involves preparing a dataset of prompt-completion pairs, uploading it, and running a fine-tuning job via their API or platform tools. This creates a custom model based on a base model (like GPT-3.5-Turbo or GPT-4) adapted to your data.
FAQ: What’s the token limit for ChatGPT?
This refers to the *context window* size. It varies by model. GPT-3.5-Turbo has versions with 4k or 16k tokens. GPT-4 has 8k and 32k versions. GPT-4-Turbo and GPT-4o offer a large 128k token context window. This limit includes both your input prompt and the generated output.
FAQ: What’s the AI presence penalty?
It’s the mechanism that reduces the likelihood of a token being generated if that token has already appeared anywhere in the generated text, regardless of frequency. Encourages topic diversity.
