Codex CLI

Codex CLI talks to UberLLM through the Responses API at https://api.uberllm.dev/v1. Codex 0.95 and later only speak the Responses API (wire_api = "chat" was removed), and UberLLM serves it on every chat model. Tested with Codex 0.166.0 on 2026-10-30: shell commands, file edits and multi-step tasks.

Setup

  1. Create a key in Dashboard → Keys and add credit.

  2. Export it in your shell profile (~/.zshrc or ~/.bashrc):

    export UBERLLM_API_KEY="ull_..."

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

    model = "deepseek/deepseek-v4.1-flash"
model_provider = "uberllm"
web_search = "disabled"

[model_providers.uberllm]
name = "UberLLM"
base_url = "https://api.uberllm.dev/v1"
env_key = "UBERLLM_API_KEY"
wire_api = "responses"

  4. Open a new terminal and run codex in your project.

base_url must end in /v1: Codex adds /responses. env_key is the name of the environment variable that holds the key.

Options

Setting Why
model Any chat model id from the catalog. Override per run with codex -m <id>.
model_context_window Codex assumes 272,000 tokens for models outside OpenAI's own list. Set the model's real context size so Codex compacts the conversation in time.
model_reasoning_effort "low", "medium" or "high", passed on to models that think.
web_search = "disabled" Codex's web search runs on OpenAI's servers and is not offered by other providers; UberLLM leaves the tool out either way.

Non-interactive runs for scripts and CI:

codex exec --skip-git-repo-check "fix the failing test in tests/test_api.py"

How it works

  • Codex sends the whole conversation on every turn with store: false. UberLLM keeps nothing between calls and Codex needs nothing kept.
  • Codex's tools (exec_command, apply_patch, update_plan, MCP servers you add) are function and custom tools from the API's side, so they work on any model with tool calls.
  • Each call appears in Dashboard → Activity with the app name codex and its cost.

Troubleshooting

Symptom Fix
wire_api = "chat" is no longer supported Set wire_api = "responses".
Missing environment variable: UBERLLM_API_KEY or 401 Export the key in the terminal Codex runs in.
404 on every turn base_url must be https://api.uberllm.dev/v1.
"Model metadata for … not found. Defaulting to fallback metadata" Harmless for models outside OpenAI's list; set model_context_window.
The model answers but never runs commands Use a model with reliable tool calls (DeepSeek, GLM, Kimi, Qwen Coder, Claude, GPT).
402 Add credit, or raise the key's spend limit.
