[OpenAI Increases Default Context Length of GPT-6.1 Sol to 500,000 Tokens] Tibo Sottiaux, head of OpenAI Codex, posted on the X platform that the default context length for GPT-6.1 Sol, when used via Codex and ChatGPT Work, has been increased from 272,000 tokens to 500,000 tokens, an approximately 80% increase. This helps reduce the occurrence of context compaction, making it more suitable for tasks requiring the retention of large amounts of context over extended periods. Users can still adjust this setting, with the maximum context length for GPT-6.1 Sol being 1,000,000 tokens. He also mentioned that the default context length will be further increased in the future.
