@furkan-bayram132 did you enable it in your copilot settings? Also note that some of their api is down and could be causing issues too

[furkan-bayram132]

@rekram1-node yes i enabled it

[rekram1-node]

Do u have any mcp servers? Their api may be erroring due tot hat

I'm having the same issue and it is failing when I ask to contact the context7 MCP server.

[furkan-bayram132]

i don't have any mcp servers

I see the same thing in opencode 0.15.31 (I see a lot of bugs constantly fixed in 1.x so thought I'd wait a little). No MCP or LSP servers here.
And as mentioned on your X post, Gemini 3 in Zen is also throwing that Generative AI API key error.

@rversteegen can u show me opencode auth list

and then try:

opencode run hello --print-logs --model opencode/gemini-3-pro

[rversteegen]

Oh, noone mentioned this detail yet: the agent always performs one tool call successfully, and then shows the error. I tell it to continue and it repeats:

I see a model=gpt-5-nano failed to generate title API error in there, but the titles do generate just fine when not using opencode/gemini-3-pro, so I guess it's because the whole session is errored.
Anyway it's about time I upgraded to opencode 1.x unless you want me to continue testing with 0.15 for any reason.

i am having this same error, using the latest version of opencode
