Support codex model_provider

[benjaminbauer]

Currently t3code does not support model_providers for codex. When I try sending a prompt, I get

These headers are sent by the codex cli.

Environment

OS: Linux (Arch)
t3code version: 0.0.10
Codex CLI version: 0.114.0

Custom provider: Portkey (model_provider = "portkey" in ~/.codex/config.toml)
Codex CLI config (working standalone)

model_provider = "portkey"

[model_providers.portkey]
base_url = "https://api.portkey.ai/v1"
env_key = "PORTKEY_API_KEY"
wire_api = "responses"

Running codex directly from the terminal works without issues.

seems to work for me.

Can you maybe help me reproduce the issue locally?

[benjaminbauer]

you mean you can use models via portkey in t3code?

[benjaminbauer]

could be, that the error I am seeing is just a weird behavior of portkey to signal missing auth. I have a suspicion, that portkey can deduce the correct parameters depending on the model configuration. When the env var is not correctly handed down, then the auth on portkey fails and it cannot fetch the config, thus falling back on requiring the headers.

This should probably be solved first, so we are sure, that t3code handles env_var #317

Repro would require a working portkey instance

update:

I tried to hard-code my API key in ~/.codex/config.toml. I removed env_key = "PORTKEY_API_KEY" and tested both with

experimental_bearer_token = "..."

and

http_headers = { "x-portkey-api-key" = "..." }

I confirmed:

• codex cli works with either of them
• codex cli does not work when I have neither of them (sanity check)
• t3code still does not work with either option

seems to be working for me.
