jsonformer VS pydantic-chatcompletion

- Tools like jsonformer https://github.com/1rgs/jsonformer are not possible with OpenAIs API.

How does this compare in terms of latency, cost, and effectiveness to jsonformer? https://github.com/1rgs/jsonformer

You're correct with interpreting how the model works wrt it returning tokens one at a time. The model returns one token, and the entire context window gets shifted right by one to for account it when generating the next one.

As for model performance at different context sizes, it's seems a bit complicated. From what I understand, even if models are tweaked (for example using the superHOT RoPE hack or sparse attention) to be able to use longer contexts, they still have to be fined tuned on input of this increased context to actually utilize it, but performance seems to degrade regardless as input length increases.

For your question about fine tuning models to respond with only "yes" or "no", I recommend looking into how the jsonformers library works: https://github.com/1rgs/jsonformer . Essentially, you still let the model generate many tokens for the next position, and only accept the ones that satisfy certain criteria (such as the token for "yes" and the token for "no".

You can do this with openAI API too, using tiktoken https://twitter.com/AAAzzam/status/1669753722828730378?t=d_W... . Be careful though as results will be different on different selections of tokens, as "YES", "Yes", "yes", etc are all different tokens to the best of my knowledge

From here, we just need to continue generating tokens until we get to a closing quote. This approach was borrowed from Jsonformer which uses a similar approach to induce LLMs to generate structured output. Continuing to do so for each property using Replit's code LLM gives the following output:

https://github.com/1rgs/jsonformer or https://github.com/microsoft/guidance may help get better results, but I ended up with a bit more of a custom solution.

I think function calling is just JSONformer idk: https://github.com/1rgs/jsonformer

Hey everyone,

So, I stumbled upon this really cool idea of using Pydantic to deserialize and validate OpenAI's outputs over on this HN thread https://news.ycombinator.com/item?id=35821748.

It got me thinking about how I'd like a slightly tweaked API to better fit my own needs. I also found some neat stuff in jiggy-ai's Pydantic implementation for chat completion https://github.com/jiggy-ai/pydantic-chatcompletion/blob/mas..., and picked up tips from various blog posts and comments on how to up the game with the quality of a model's output by providing examples.

So, I cooked up this library - just about 200 lines of code, but it's got some nice features and it's fully tested. I hope some of you find it useful.

I'd love to hear your thoughts and feedback. Cheers!

Nice project! I took some inspiration from this as well as https://github.com/jiggy-ai/pydantic-chatcompletion/blob/mas... to create the following:

I tried to make the API as intuitive as possible and added the ability to provide examples to improve the reliability and quality of the LLM's output.
