GPT-6 Astra's launch included a way for long coding sessions to recover details that no longer fit in the model's immediate context windowThe maximum amount of text a model can consider at once — its working memory for the current conversation or task.Full definition →. OpenAI described an experimental Codex feature that keeps notes across context windows and makes earlier messages and tool outputs searchable, instead of compressing everything into one summary each time the context fills. The announcement covers it in its coding section.
The useful change is a path back to earlier evidence. If a requirement or test result was omitted from the notes, the AI agentAn AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.Full definition → can search the prior interaction instead of depending entirely on the latest summary.
