OpenAI 与 Anthropic 一周动态：Sora 重启谈判、Scion 自研源码管理落地
这期干货不少：Sora 可能借新公司复活，Anthropic 用自研 Scion 替掉 git，内部 Claude 还解开了 25 年的 ECDSA 种子谜题，科技八卦和硬核内容都有。
The Information 报道 OpenAI 正洽谈通过 Jeffrey Katzenberg 与前 Sora 负责人 Bill Peebles 共同创立的初创公司重启 Sora，成交后 OpenAI 将持有股权。OpenAI 办公室发现隐藏录音设备，借助自家模型追查到涉案员工并由 FBI 逮捕。Anthropic 自研源码管理工具 Scion，用 5 个月将 monorepo 迁出 git，日均合并从约 2500 次升至 3 万次以上，其内部 Claude 研究模型还破解了 NIST ECDSA 曲线种子这一 25 年悬案。模型侧 GPT-6 Pro 提速并支持多智能体并行，GPT-5.5 已从 ChatGPT 与 Codex 退役，GPT-4o 和 GPT-4.1 将于 2027 年 1 月 14 日退出 API。
OpenAI and Anthropic weekly recap, week 42 of 2026: Sora revival talks, a hidden recorder at OpenAI, Anthropic's own source control Scion, a solved ECDSA mystery and more
The Information reports OpenAI is in talks to revive Sora through a startup co-founded by Jeffrey Katzenberg and former Sora lead Bill Peebles, with OpenAI taking equity if a deal closes
OpenAI says they found a hidden recording device in an office, used their models to trace it to an employee, and the FBI made an arrest
The Information also reports early OpenAI talks to buy security firm Trail of Bits
ChatGPT now gathers information across open Chrome tabs through OpenAI's extension, and can control them in ChatGPT Work
OpenAI's GPT-6 Pro got faster with better tool use and multiple agents working in parallel
GPT-5.5 is retired from ChatGPT, ChatGPT Work and Codex, API unaffected, and OpenAI's GPT-4o and GPT-4.1 leave the API on January 14, 2027
Anthropic says strengthened defenses against distillation attacks cut what distillers can harvest by 90 to 99 percent
An internal Claude research model at Anthropic solved a 25-year-old mystery about the NIST ECDSA curve seeds, tracing them to a C library random generator seeded with Unix timestamps
Anthropic built Scion, their own source control, and moved their monorepo off git in five months as daily merges went from roughly 2,500 to over 30,000
Claude Code desktop was reworked for many sessions side by side, Code Review is generally available for Claude Team and Enterprise, and Opus 5.5 fast mode left research preview on the Claude Platform
Anthropic reports agent hours passed human hours internally in March, opened a Singapore office, and says Democracy Works voting information comes to Claude ahead of the US midterms, and more
