fix: Add `max_tokens` to chat completions #934

Closed cecheta closed 1 month ago

cecheta commented 1 month ago

Purpose

GPT-4 has a default max tokens of 16, meaning the captions generated were very small. This PR adds the AZURE_OPENAI_MAX_TOKENS to the chat completions call, so it will default to 1000 tokens, and can be conifgured.

Does this introduce a breaking change?

[ ] Yes
[x] No

How to Test

Do we know why that's the default? Is it more expensive?
