  "notes": "Rates per million tokens in USD — OpenAI's native billing currency for the Codex CLI (agent ids codex/openai). GPT-5.5 was the standing model as of 2026-06 (codex CLI 0.13x reports model gpt-5.5); the 2026-04-23 GPT-5.5 release doubled the GPT-5 line to in 5 / out 30. cache_read is the documented cached-input rate ($0.50/M = 90% off input). Field convention matches the deepseek/kimi snapshots: cache_create = cache-miss input rate (OpenAI levies no separate cache-write surcharge, and codex sessions report no cacheWrite tokens, so this only ever multiplies near-zero cacheWrite). gpt-5 / gpt-4o retained for currency resolution of legacy/aliased codex model ids. NOTE: default_model is intentionally kept at the prior snapshot's kimi-k2.6 so the GLOBAL unknown-model fallback (and its frozen difftests) is unchanged — this vendor snapshot only ADDS the gpt-* price keys and their USD currency.",
