OpenAI increased GPT-6.1 Sol default context length from 272k to 500k tokens in Codex and Work environments. This 80% boost reduces compression and memory lapses for long tasks. Users can manually extend up to 1M tokens. Crucially, OpenAI removed extra charges for long context, lowering usage costs. This move aims to enhance user experience and compete in the large model market by making extended context a standard, cost-free feature rather than a premium add-on.
