Anthropic Launches Claude Sonnet 5, Etched Reveals Stealth ASIC Exit, and Meituan Releases 1.6T Open Model
English summary
Anthropic released Claude Sonnet 5 as its new default mid‑tier model, offering 1M‑token context, improved coding benchmarks (57% on CursorBench vs 49% for Sonnet 4.6), and promotional pricing of $2/M input and $10/M output through August. Meanwhile, ASIC startup Etched disclosed it has $800M in funding, $1B+ in customer contracts, and is shipping first inference racks this summer. In open‑source news, Meituan published an open‑weights 1.6T‑parameter MoE model trained on domestic AI accelerators, and Huawei open‑sourced OpenPangu‑2.0‑Flash (92B total, 6B active).
Chinese summary
Anthropic 发布新默认中端模型 Claude Sonnet 5，支持 100 万 tokens 上下文，编码基准成绩提升（CursorBench 57% vs Sonnet 4.6 的 49%），并提供限时促销价格（输入 $2/百万 tokens，输出 $10/百万 tokens，截至八月）。ASIC 创业公司 Etched 公开了 $8 亿美元融资、$10 亿以上客户合同，并将在今夏交付首批推理机架。开源方面，美团发布 1.6 万亿参数 MoE 开放权重模型，训练基于国产 AI 加速器；华为开源 OpenPangu‑2.0‑Flash（92B 总参数，6B 活跃参数）。
Key points
Anthropic launched Claude Sonnet 5, a mid‑tier agentic model with 1M‑token context, improved coding benchmarks, and promotional $2/$10 per‑million‑token pricing.
Anthropic 发布 Claude Sonnet 5，这是一款中端代理模型，支持 100 万 tokens 上下文，编码基准成绩提升，并推出每百万 tokens 2 美元（输入）/10 美元（输出）的促销定价。
Etched, a stealth ASIC startup, revealed $800M in funding, $1B+ contracts, successful A0 tapeout, and first inference racks shipping summer 2026.
秘密 ASIC 创业公司 Etched 公布：融资 8 亿美元，手握超 10 亿美元客户合同，A0 流片成功，首批推理机架将于 2026 年夏季发货。
Meituan released an open‑weights 1.6T‑parameter MoE LLM, reportedly trained entirely on Chinese AI superpods, and Huawei open‑sourced OpenPangu‑2.0‑Flash (92B/6B active).
美团发布开放权重的 1.6 万亿参数 MoE 大模型，据称完全在国产 AI 超级计算集群上训练；华为开源 OpenPangu‑2.0‑Flash（92B 总参数，6B 活跃参数）。
Third‑party evaluations show Sonnet 5 outperforms its predecessor on coding/agentic tasks but can cost more per task than Opus 4.8 due to higher token usage, while Fable 5 remained absent.
第三方评测显示 Sonnet 5 在编码和代理任务上优于前代，但由于更高的 token 消耗，每任务成本可能高于 Opus 4.8；Fable 5 仍未推出。
