OpenAI restores ChatGPT 5-hour usage limit
OpenAI is reintroducing a 5-hour usage limit for ChatGPT Plus users of Codex and ChatGPT Work, effective August 26, 2026. The shorter limit had been removed in July 2026 after a security incident; OpenAI's Product Leader Thibault Sottiaux announced the reinstatement via social posts. The company says the 5-hour cap helps smooth server load and lets it set a higher weekly limit while warning casual or new Plus subscribers when they approach their compute budget. Pro-tier customers remain unaffected for now (their 5-hour reset remains disabled), with Pro pricing noted at $100 or $200 depending on the level.
A major AI provider (OpenAI) changing access and usage limits affects developer and user access to LLM compute, subscription tier differentiation, and operational load management—relevant to companies integrating or relying on ChatGPT services but not industry-shifting.

OpenAI launches ChatGPT Pro to boost Codex usage
OpenAI introduced a new ChatGPT Pro subscription tier aimed at developers using its Codex coding agent. The offering includes a $100/month (≈€103) Pro plan and a $200/month Pro plan with significantly expanded Codex usage limits (5x and 20x versus ChatGPT Plus, respectively); OpenAI temporarily increases the $100 tier’s boost to 10x until May 31. The update follows Codex reaching three million weekly active users; CEO Sam Altman said usage limits will be reset at each additional million up to ten million. OpenAI recently released a Codex mobile app, the GPT-5.3‑Codex model, and the Frontier development platform. The Pro subscription provides access to GPT-5.4 Pro Reasoning, unlimited file uploads, GPT‑5.3 usage, individual GPTs, and experimental features. OpenAI is also testing a parallel workflow feature called Scratchpad. Thibault Sottiaux from the Codex team clarified rate-limit wording publicly on X.
OpenAI halves ChatGPT Pro usage, introduces $500 tier
OpenAI has revamped its ChatGPT Pro subscription plans, effectively halving the usage allowance for the $200 tier while keeping the price unchanged. New Pro 200 subscribers now receive 10x the Plus allowance instead of 20x, reducing the value proposition for heavy users, especially those running AI agents like Codex. To compensate, OpenAI has introduced a new $500 Pro 500 tier offering 25x usage and ultrafast access to GPT-6 Astra. Existing Pro 200 subscribers retain their original quota until the end of October. OpenAI justifies the change by pointing to recent API price cuts for lower-tier models like GPT-6 Sol and Luna, but notes that usage of the flagship Astra model will actually halve. The move reflects the high compute costs of AI agents and signals a shift towards usage-based pricing, with advertising and transactions explored as alternative revenue streams.
OpenAI Halves ChatGPT Pro Allowance, Adds Pricier Tier
OpenAI has relaunched its $200 ChatGPT Pro plan with a significant reduction in usage, cutting the included allowance from 20 times to 10 times the base Plus plan. A new $500 Pro 500 tier offers 25 times the allowance and exclusive access to the 'Ultrafast' mode for GPT-6 Astra. The change, confirmed by Codex chief Thibault Sottiaux, means the Pro 200 tier now costs the same per usage unit as other tiers, effectively eliminating the previous volume discount. The reduction is partly offset by recent API price cuts for cheaper models, but heavy users of the top model will see their effective usage halved. The move highlights the rising costs of powering AI agents, which consume massive amounts of tokens, and may signal a shift toward pay-per-use models for advanced AI. OpenAI is also exploring alternative revenue streams like advertising and transaction fees to keep agents affordable.
