Anthropic releases Claude Sonnet 5.5, scores 70.6% on Terminal-Bench 4.0 at unchanged pricing

Claude Sonnet 5.5 发布，Terminal-Bench 4.0 得分 70.6% 且价格不变

Anthropic dropped Claude Sonnet 5.5 with a 70.6% score on Terminal-Bench 4.0, a huge jump from Sonnet 5's 10.3%. Pricing stays at $2/$10 per million input/output tokens. The post doesn't disclose architecture, training details, or exact availability, so I'd wait for third-party benchmarks before getting too excited.

Why it matters: Anthropic's flagship model gets a generational update with a massive benchmark leap and unchanged pricing — a same-day must-write. Deduction for single-tweet sourcing and missing architecture/timeline details; third-party verification pending.
