💻 OpenAI's new model migrates old COBOL code LINK
  • OpenAI says its latest models are now substantially better at reading and migrating legacy code in languages like COBOL, Fortran and Visual Basic, targeting the roughly 40% of banks still running COBOL systems facing a shrinking pool of programmers.
  • On OpenAI's new MultiLangBench suite, which tasks models with building SQLite-compatible database engines across 20 languages, GPT-6 Astra scored an 87.4% average pass rate, more than triple GPT-5.6 Sol's, though COBOL stayed hardest.
  • On COBOL-to-C++/Java/Kotlin/Python/Rust migrations that must preserve rounding and missing-record behavior, GPT-6.1 Sol hit 97.9% accuracy at high reasoning effort, dropping to 86.6% at low effort, though OpenAI warns production use still needs expert review against business rules.
⚡ New diffusion AI beats GPT-6's fast model LINK
  • Inception released Mercury 3, a diffusion language model it says beats speed-optimized rivals GPT-6 Luna and Claude Haiku 5.5 on quality benchmarks while running four to eight times faster.
  • The model generates over 1,000 tokens per second on standard NVIDIA GPUs and supports a 1M-token context, while being over 40x larger than Mercury 1 yet holding the same speed.
  • It's available via the Inception API, Baseten, OpenRouter, and Vercel, and is OpenAI API-compatible so developers can swap it in without major code changes.
🔬 Gemini AI finds new fusion field solutions LINK
  • Google's Gemini 4 Argon helped researchers extend exact mathematical solutions for the magnetic fields that confine fusion plasma, building on September 2026 work that overturned a conjecture physicist Harold Grad proposed back in 1967.
  • Running through Google's Antigravity environment, multiple agents explored Matt Landreman's earlier results and, within hours, found ways to break a geometric symmetry restriction, yielding new configurations researchers could verify as reference cases for magnetic-equilibrium software.
  • The work gives teams additional exact solutions to test plasma-modeling code against, not a path to commercial fusion, and the AI candidates still required manual derivation checks to confirm they were mathematically consistent.
🎬 Kling AI 4.0 adds stereo audio LINK
  • Kling AI 4.0 is out, adding two-channel stereo audio and improved lip sync across more than ten languages including German, English, Japanese, Korean, and Spanish, alongside higher resolution and more precise controls.
  • The model generates up to 30 seconds in a single pass, accepts up to ten keyframe images, and comprehends prompts up to 8,000 tokens, with its "Omni Reference" system taking up to 15 reference assets per generation.
  • Kling 4.0 now works through MCP and CLI for agent-driven automated workflows, and a lower-cost Flash variant tops out at 720p and 20 seconds, though API pricing and support are still listed as "coming soon."
☁️ Cloudflare's Clairic reads docs cheaply LINK
  • Cloudflare has released Clairic, a model for pulling structured data from documents that it says runs faster and cheaper than LLMs, now in preview on Workers AI with open weights to follow.
  • Developers name the fields they want and Clairic returns matching values with a confidence score in a single pass rather than generating token by token, returning "null" for missing values and handling simple calculations and forecasts.
  • In a sample complaint-handling chain with decision model Clef and GLM-5.3, the pipeline runs in 19.3 seconds versus 61.7 for GLM-5.3 alone at nearly double the cost, though Clairic can't yet reliably handle longer calculation chains.

🛠️ Engineering & Practice

> Cutting our inference bill by 68% by being obsessive about optimization: GitLab cut its AI code-reviewer cost 68% by sharing cached prompt text across repositories, trimming wasted model calls, and switching to cheaper, more efficient models.
> The thin orchestrator: How we made our AI agents more reliable by giving the router less to do: Keep the AI agent that routes tasks free of any reasoning, so failures stay contained and specialist agents handle each domain reliably.
> Accelerating Mamba-2 with high-performance forward pass kernels in NVIDIA CUDA Tile: Writing the Mamba-2 sequence model's forward pass in Nvidia's Python kernel language cuTile made it 1.14x to 1.82x faster than a comparable Triton version.
> One search, two layers: Compiler controls inside PyTorch Helion using NVIDIA CompileIQ: Letting PyTorch's kernel tuner search compiler-level assembly settings alongside its usual choices squeezes extra speed from GPU code already considered fully optimized.
> MPS in PyTorch 2.15: PyTorch 2.15 speeds up local AI models on Apple Macs, adding memory-saving formats and faster decoding so Macs become a practical place to run and train models.
