Infer × Codex
Your models in Codex.
Pay as you go.
Use GPT-6 Astra, GPT-5.6 Sol and other available models through one Infer API key. Add wallet credit, set a key spend cap, and pay for the tokens you use.
No card required to sign up. Add credit before your first paid request.
Prefer guided setup? Use the open-source Infer Setup tool on macOS, Windows, or Linux.
Configuration generator
Choose the selector Codex should request.
The model family stays explicit. The price option changes the routing policy without changing the Responses integration.
Verify the selected model is operational, the account email is verified, and the wallet has service credit.
# Waiting for the current Infer catalog…Merge this block with your existing user-level configuration. Do not replace unrelated settings.
Install and verify
Three deliberate steps.
- 01
Save the provider at user level.
Codex requires custom provider definitions in
~/.codex/config.toml. A project-local.codex/config.tomlcannot define or override these provider keys. - 02
Set the key outside the file.
export INFER_API_KEY="your-infer-key"Keep the API key in the environment. The generated block contains only the environment-variable name.
- 03
Run the real agent loop.
Test the tools, streaming events, output limits, and error paths your workload actually uses. A “hello world” response is not compatibility proof.
Domain-owned Agent Skill
Install the setup boundary, not a brochure.
The skill reads Infer’s live catalog and status before it recommends a selector. It keeps keys in the environment and stops before a paid check when the selected model is unavailable.

The command disables that CLI’s optional usage telemetry, fetches Infer’s domain-owned discovery index, and verifies the skill’s SHA-256 before installation. Inspect the index.
