Documentation [1] says:

The small_model option configures a separate model for lightweight tasks like title generation. By default, OpenCode tries to use a cheaper model if one is available from your provider, otherwise it falls back to your main model.

I would expect that if you set a local model it would just use the same model. Or if for example you set GPT as main model, it would use something else from OpenAI. I see no mentions of Grok as default

i ran it through mitmproxy, i am using pinned version 1.2.20, 6 march 2026, set up with local chat completions.

on that version, it does not fall back to the main model. it silently calls opencode zen and uses gpt-5-nano, which is listed as having 30 day retention plus openai policy, which is plain text human review by openai AND 3rd party contractors.

i see they removed the title model on v1.2.23.

i was so annoyed i made an account here today
