Has anyone already created a file of OpenAI API documentation for updating a LLM's coding knowledge?

Yes, but in two phases. I download OpenAI's OpenAPI specification , which is HUGE (68K tokens). I do some manual edits to remove most of what I don't need (e.g. images, assistant api, fine-tuning, tts/stt), but I don't try to be perfect. This gets me to about 10K tokens. I make a prompt that includes the specification and at the bottom I tell it to summarize what I care about into a prompt that I can use for code gen. (Maybe "Given the above OpenAPI specification, Generate minimized documentation for Python chat completion creation, usable as a GPT prompt for GPT code generation.".) This wasn't possible before the 128K GPT-4 window. Then I prefix that generated prompt to my prompts. It's not quite so simple. It takes some trial-and-error. Another option is to use the html documentation. I prefer to send it through pandoc to attempt to convert it to markdown, which uses far fewer tokens than html. I've done this with other APIs. API documentation often consists of way too many tokens to be practical for all your prompts, so I use AI to minimize it for my specific need. More on reddit.com

Thoughts on openai's new Responses API

I think in general, companys creating api's for general adoption has always been a bit of a lock-in attempt, and your right to be a little bit skeptical. More on reddit.com

OpenAI API doc as .pdf or .txt

Why don’t they train the models on the updated API docs?

I had an issue two days ago and gave o1-preview the README from GutHub. It then said “This may violate our content policy”.

I argued. This is YOUR README file, it’s 100% within your content policy!

It goes, “Oh, yeah, you’re right, let’s get started then!”

Introducing GPT-5.2 | OpenAI

2 days ago - For tasks that benefit from thinking beyond the maximum context window, GPT‑5.2 Thinking is compatible with our new Responses /compact endpoint, which extends the model’s effective context window. This lets GPT‑5.2 Thinking tackle more tool-heavy, long-running workflows that would otherwise be limited by context length. Read more in our API documentation⁠(opens in a new window).

r/ChatGPTCoding on Reddit: Has anyone already created a file of OpenAI API documentation for updating a LLM's coding knowledge?

December 3, 2023 -

In regards to getting a model to assist with coding tasks it's helpful to upload updated API documentation. Has someone already taken on the task of creating and maintaining an openai API documentation text file or PDF for this purpose? I was wondering if anyone has optimized the documentation for this task already before I make my own.

Yes, but in two phases. I download OpenAI's OpenAPI specification , which is HUGE (68K tokens). I do some manual edits to remove most of what I don't need (e.g. images, assistant api, fine-tuning, tts/stt), but I don't try to be perfect. This gets me to about 10K tokens. I make a prompt that includes the specification and at the bottom I tell it to summarize what I care about into a prompt that I can use for code gen. (Maybe "Given the above OpenAPI specification, Generate minimized documentation for Python chat completion creation, usable as a GPT prompt for GPT code generation.".) This wasn't possible before the 128K GPT-4 window. Then I prefix that generated prompt to my prompts. It's not quite so simple. It takes some trial-and-error.
