OpenAI 发布 GPT-5.6，性能超越 Claude Mythos 5
openai 在美国政府强制延迟后发布了 gpt-5.6 'sol' 模型。该模型每百万 token 价格为 5/30 美元，在编码基准测试中击败了 claude mythos 5。
openai released gpt-5.6 'sol' models thursday after the department of commerce approved public access, lifting restrictions previously placed on the initial partner-only rollout. the 'sol ultra' model achieved 91.9% on terminalbench 2.1, surpassing google's gemini 3.1 pro preview at 70.7% and claude mythos 5 at 88.0%, while matching claude on security tasks using significantly fewer tokens. priced at $5/$30 per million input/output tokens, gpt-5.6 is nearly half the cost of its competitors, setting a new price-to-performance standard for the market. the company criticized the regulatory hold, noting that binding standards for ai releases remain absent despite the latest executive orders.
