OpenAI Reduces Codex Context Length
petrusenko_max · x · 2026-07-20
A post pointed out that OpenAI has reduced Codex's context length from 372k tokens to 272k.
This means that when processing large codebases or complex workflows, more attention is needed for prompt design and token efficiency; previous use cases that relied on ultra-long context will be affected.
