rate limits

OpenAI will reinstate a five-hour usage limit for Codex and ChatGPT Work on Plus subscriptions starting August 25, 2026, after weeks of running only a weekly cap. Pro $100 and Pro $200 plans remain exempt from the change for the foreseeable future.

OpenAI is removing rate limits on text-only prompts for Free and Go tier ChatGPT accounts starting next week. Image generation, file uploads, and voice mode will still be capped, and GPT-5.6 Luna becomes the new default model for those tiers.
