Description

When using gpt-5, I get:

400 Unsupported parameter: 'max_tokens' is not supported with this model. Use 'max_completion_tokens' instead.

The reason is that only the o-series models apply the patch, gpt-5 doesn't trigger it:

continue/core/llm/llms/OpenAI.ts

Line 143 in ab4bb9c

// a) use max_completion_tokens instead of max_tokens

Moving forward we are trying to get models support into Discussions for easier discoverability.
