OpenAI、GPT-5.6をリリースしClaude Mythos 5の王座を奪う
openaiは、米政府による遅延を経てgpt-5.6「sol」モデルをリリースした。このモデルのコストは100万トークンあたり$5/$30で、コーディングベンチマークではanthropicのclaude mythos 5を上回る。
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.
