Codex

Add a custom Responses provider to Codex CLI

Configure

Add this to ~/.codex/config.toml:

model = "your-model"
model_provider = "bianxieai"

[model_providers.bianxieai]
name = "Bianxie AI"
base_url = "https://api.bianxie.ai/v1"
env_key = "BIANXIE_API_KEY"
wire_api = "responses"

Set BIANXIE_API_KEY=API_KEY, then start Codex. Use /status to verify the provider and model before asking it to inspect a directory without changes.

If the key is missing, ensure env_key exactly matches the environment variable. For 404, retain /v1. For request-shape errors, keep wire_api = "responses". The model must support Responses tools.
