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.

How does it compare to using GPT 5.4 inside Codex?

Things that make an an OpenCode fanboy 1. OpenCode source code is even more awesome. I have learned so much from the way they have organized tools, agents, settings and prompts. 2. models.dev is an amazing free resource of LLM endpoints these guys have put together 3. OpenCode Zen almost always has a FREE coding model that you can use for all kinds of work. I recently used the free tier to organize and rename all my documents.

Earlier quoted context omitted.

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.

Or have Claude write the code and Gemini review it. (Was using GPT for review until the recent Pentagon thing.)

The 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).

I dont understand this, what is the difference, technically!

Was it not obvious what the OP meant by blacklisted?

This replaced Aider for me a couple months back.

I 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.
