ChatGPT's 1M-token context can be unlocked, but requests over 272K tokens cost more
SimplyAnnisa · x · 2026-08-17
Tibo posted the config to unlock the full 1M-token context window in ChatGPT — surprisingly, it works through regular accounts, not just API keys. The tradeoff: OpenAI's own pricing page confirms that past 272K input tokens, the entire request moves to a higher pricing tier. Such flags usually stay undocumented until someone reverse engineers them.
