They are different models. OpenCode is trying to be a claude code/codex replacement, where-as pi is something you build yourself, kind of trying to be an emacs type thing compared to vs-code. As in emacs it is more common to write your own extensions, where as in vs-code most people just download them.

I keep butting into the question of; why opencode, when you've got codex available? Codex is open source as well, and i can't seem to picture a situation where one would want Opencode over Codex.

As far as I can tell, they tick the same boxes- but one has the support of a big boy model provider.

Well, the reason is simple: over the past several months, it has become very difficult to use Codex with non-OpenAI models. They removed the old edit tool that didn't require OpenAI's free form tool calling (that no other LLM host supports), they are adding tools to every request of a type that break most LLM hosts unless you use a proxy to filter them out, they add a "developer" role to some messages which breaks some chat templates, etc.

If someone wanted to fork Codex and make a community-maintained version that supports third party models, that would be great, because I liked Codex better than OpenCode for the most part.

Maybe you've found workarounds. Maybe you're using an old version of Codex. Maybe you have your own soft fork. I don't know. But I used to be able to use Codex with self-hosted models, and I gave up on that about a month ago as they kept breaking that.

Ah, I wasn't aware things regressed there. Yea certainly workarounds n soft fork sorts of things definitely would work- but thats a bummer than things have changed.

From watching Pr's and issues- seems like openai at least wants to come across as if theyre supporting non-oai models :/

[coder543]

Yeah... one of the relevant issues: https://github.com/openai/codex/issues/11940#issuecomment-45...

You would think they would support their own GPT-OSS model, but, not really anymore. I wish they would release a GPT-OSS 2, but this doesn't fill me with confidence.

If you care about privacy at all, you can route your Opencode requests through an inference provider that does not retain any logs or data. It is also much cheaper. So if your boxes include `Privacy` and `Affordability`, then no, they don't tick the same boxes.

[agentdev001]

You can use the Codex harness with non-openai providers if you want.

Not very well, if you're using the latest version of Codex. They broke a lot of stuff that made that possible.

[arcanemachiner]

Pretty sure you need to use an older version of Codex for this to work.

I think they meant using Codex with non-openai providers?
