Codex Plus Pool — 0.03x of official OpenAI pricing. Supports gpt-6-astra, gpt-6.1-sol, gpt-6-sol, gpt-6-luna, gpt-5.6-sol, gpt-5.6-terra, gpt-5.6-luna, and codex-auto-review.
Codex Pro Pool — 0.05x of official OpenAI pricing. Pro 20x accounts. Supports all models above.
Plus Pool and Pro Pool use the same real OpenAI models as the official API. However, OpenAI has been randomly downgrading model quality on some accounts. In Plus Pool, Astra and Sol (gpt-6-sol and gpt-5.6-sol) are currently affected — use with caution. In Pro Pool, problematic accounts and requests are dynamically isolated, and quality is good.
Image generation (GPT Image 2 and GPT Image 2.5) is available through a dedicated image pool at $0.015 per generated image via CE Image Studio or the /v1/images API.

Notes
* OpenAI's promotional pricing on gpt-5.6-sol does not apply to Codex subscriptions, so CE is unable to pass on the discount. Prices shown above reflect subscription credit rates.
GPT-6 series and GPT-5.6 cache writes are 1.25x input. GPT-5.6 has a guaranteed 30-minute cache lifetime. CE does not charge for cache writes.
Context over 272K tokens is billed at 1.5–2x by OpenAI. CE applies the same long context rates.
Based on our testing, GPT-5.6 series models show noticeable quality degradation above 400K context.
The Codex client defaults to a 258K context limit — using 1M context requires manual configuration.
Caching is optimized for Codex and OpenCode. Third-party clients such as Hermes may experience lower cache hit rates — please test on your own.
If calling the API directly, pass session_id and prompt_cache_key to enable cache hits. You can observe how the Codex client constructs these fields to guide your own implementation.
CE's GPT API is powered by Codex. If you do not specify the instruction field, Codex's default system prompt will be used. To use your own system prompt, set the instruction field explicitly.
