OpenAI Preps $500/Month ChatGPT Pro Max Plan, Possibly Powered by Cerebras
testingcatalog · x · 2026-09-25
- TestingCatalog found unreleased references to a ChatGPT "Pro Max" plan priced at $500/month, offering "Fastest Work and Codex" and possibly higher usage limits (unconfirmed).
- The tier targets developers and professionals running long agentic workloads and multi-day Codex jobs, where inference speed matters most.
- Context suggests Cerebras infrastructure: OpenAI already uses Cerebras for its latency-focused GPT-5.6 Sol Ultrafast mode (up to 14x speedup, limited preview), though no official link to Pro Max has been confirmed.
