If I wanted to switch from Claude Code to this - what openai model is comparable to opus 4.6? And is it the same speed or slower/faster? Thank you!
GPT 5.4 has been the winner this week. Last week Opus 4.6. You can use both in OpenCode.

#23Claude Code subscription is still usable, but requires plugin like https://github.com/griffinmartin/opencode-claude-auth

You can still use OpenCode with the Anthropic API.
Yep. That's what I do. Just API keys and you can switch from Opus to GPT especially this week when Opus has been kind of wonky.

#26The Agent that is blacklisted from Anthropic AI, soon more to come. I really like how their subagents work, as a bonus I get to choose which model is in which agent. Sadly I have to resort to the mess that Anthropic calls Claude Code
They are not blacklisted. You are allowed to use the API at commercial usage pricing. You are just not allowed to use your Claude Code subscription with OpenCode (or any other third‑party harness for the record).

#30I use it with Qwen 3.5 running locally when my daily limits run out on my other subscriptions.
The harness is great. Local models are just slow enough that the subscription models are easier to use. For most of my tasks these days, the model's capability is sufficient; it is just not as snappy.
