The COBOL number that rewrites modernization math
GPT-6.1 Sol scores 97.9% on OpenAI's COBOL-migration eval at high reasoning effort (86.6% at low), up from 5.4% for GPT-5.6 Sol; GPT-6 Astra averages 87.4% on MultiLangBench across 20 languages, up from 26.8%. Legacy COBOL/Fortran/VB modernization just became an API call.
And it's cheaper per job, not just better
On MultiLangBench, GPT-6 Luna runs ~$0.77/sample vs $3.48 for GPT-5.6 Sol (about 78% less), and GPT-6.1 Sol is 39% cheaper than its predecessor on the COBOL eval. The low-reasoning tier gets you to 86.6% for a fraction of the top-effort cost, so you can batch-translate a repo without a frontier bill.
DeepSeek open-sources DeepInfer, its production engine
DeepSeek released the inference framework behind its own large-scale serving under Apache 2.0: speculative decoding, batch-invariant inference, and constrained outputs (regex / JSON schema / EBNF), running on Huawei Ascend 950 NPUs alongside NVIDIA SM100 — a real crack in the CUDA moat. Caveat: this drop is offline inference only (no KV-cache serving stack yet) and targets DeepSeek-V4.1-Flash.
Anthropic will scan your critical OSS project for free
Anthropic reportedly launched an OSS Scanner that runs periodic vulnerability scans on critical open-source projects, returning a proof-of-concept and, where it can, a proposed patch. If you maintain a load-bearing library, that's a recurring free security review you didn't have to wire up.
Sunra MCP drops image and video models into Claude
Sunra reportedly shipped an MCP server that exposes hosted image and video models to assistants like Claude and ChatGPT, billed at each provider's own API price with no markup. Build this weekend: a chat-driven 'describe it, get the clip' pipeline without gluing together five SDKs.
ChatGPT can now act inside your open Chrome tabs
ChatGPT can reportedly use your open Chrome tabs as context and take actions in them — filling forms, downloading files — rather than just reading a page you paste. Rollout scope isn't fully specified yet, but it moves ChatGPT from answering about the web to operating on it.
