Error making calls to OpenAI reasoning models #558

Originally created by @ike-grl on GitHub (Jul 8, 2025).

Originally assigned to: @thdxr on GitHub.

I just tried to set up opencode for the first time and I can't get it initialized in a repo unfortunately. I am using OpenAI (since I have a dev key provided through work) with the model @openai/codex-mini-latest.

Here's the error that comes from calling /init.

$ opencode run /init --print-logs

ERROR 2025-07-08T16:34:39 +196ms service=session error=AI_APICallError: Item 'rs_686d488fcb4081a08df0417fa4dd718b0a5d60fd71eba6e4' of type 'reasoning' was provided without its required following item.

From what I see in the developer docs for reasoning model calls for OAI, the type for reasoning has subsequent items like so:

~~It looks like this might have been fixed in vercel/ai#7167~~

This seems unrelated to the linked issue unfortunately.

@garymjr any idea when this will get merged to opencode? I just ran opencode upgrade and it's still erroring.

I tried overriding the sdk that was being loaded with the latest one from @ai-sdk/openai, but I'm still seeing the reasoning error. I'm not sure why those issues were marked as related.

Adding a check to only include reasoning messages that contain summary text fixes the reasoning error, but then the model starts running into issues calling tools, so I'm concerned there's more to it than just filtering out the reasoning messages.

I built this from source, but codex-mini frequently stops responding. ~~I haven't tried other reasoning models yet.~~ I tested o3 and it seems to be working. Codex mini and o4 mini seem to both struggle.

Adding the beast prompt to codex and o4 seems to prevent the stopping. I did notice that it seems to reference files in a way that opencode isn't parsing correctly.
