    Theo open-sources tsc-rs, a Rust port of the TypeScript 7 compiler

    Theo, creator of the T3 Stack, open-sourced tsc-rs, a line-by-line Rust port of Microsoft's Go-native TypeScript 7 compiler, type checker, and language server under MIT, pinned to typescript-go commit 673a5f17. The author reports tsc-rs is about 1.61× faster than tsc 7 and about 2.95× faster than bun check on six real-app benchmarks on an Apple M4 Pro. The port passes all 181,711 ported Go tests, and CLI output matches the Go version on 120 open-source repos except for known edge cases such as monorepo rootDir and tsc -b incremental output.

    Why it matters: The post reports a benchmarked, test-verified Rust port of the TypeScript 7 compiler, with pinned upstream and stated edge cases useful for judging its compatibility.

    Hollywood's Tech Ties Fuel Three Films on Zuckerberg, Musk and Altman

    Three upcoming films, Aaron Sorkin's The Social Reckoning, Alex Gibney's Musk, and Luca Guadagnino's Artificial, critically examine tech leaders Mark Zuckerberg, Elon Musk, and Sam Altman. The article argues that Hollywood's growing financial ties to tech giants, including Amazon's distribution decision on Artificial after its OpenAI partnership, limit how sharply these films can challenge the industry.

    Kenya's Kakuma refugees power tech microwork for dwindling, uncertain pay

    Refugees in Kenya's Kakuma camp are doing AI-related microwork, such as research for RWS's AOP Connect platform, where pay comes as discretionary "rewards" of up to $500 rather than guaranteed wages. Interviews with more than two dozen refugees found most earn far less than the maximum, and entry-level remote tech work is shrinking. Refugees who are unable to legally work in Kenya say they accept these gigs despite opaque pay criteria.

    LightOn OCR-3 now on OpenDocRouter, near Gemini 3.8 Flash at lower cost

    LightOn OCR-3 is now available on OpenDocRouter at $0.28 per 1M input tokens and $1.40 per 1M output tokens, about $3.19 per 1k pages on ParseBench. On ParseBench, the author says it sits on the Pareto frontier for open-weight OCR models, with performance similar to Gemini 3.8 Flash low at roughly 45% lower price. It is described as decent at tables, workable for charts, and quite good at grounding.

    Midjourney Adds Shared Folders and Thinking Mode in Alpha Update

    Midjourney's alpha site now lets users share folders with others as Collaborators or Viewers, with sharing by link also available. A new thinking mode lets users rerun jobs made with 8.2 standard and edit models to fix missed prompt details such as objects, layout, anatomy, and text. Sharing does not change image privacy, so non-stealth images can still appear on Explore and profiles.

    Astrophysicist uses Claude to build first complete ultraviolet sky map

    An astrophysicist worked with Claude Science to create the first complete ultraviolet map of the sky, covering regions never observed in UV. Claude located existing datasets, combined them, and filled gaps with statistical inference, taking a few days rather than weeks of human work. The map is presented as a teaching tool and an example of low-priority scientific work that AI now makes feasible.

    Agent Skills Should Be Treated as Supply Chain Components

    Tessl's talk at AI Native DevCon London argues that agent skills, which can be markdown files with instructions and bundled material, act as supply chain components that can shape agent behavior. The author says reading SKILL.md once is insufficient because risks can sit in supporting files, updates, and workspace trust settings. He identifies the danger as the combination of private context, untrusted content, and external communication, and cites research scanning roughly 4,000 public skills for issues including malware-like behavior.

    Don't sleep on domain-specific harnesses. Coding agents are great because of their harnesses, but they aren't built for creative work. Creative work needs its own harness. Voyager looks great. It's an open harness for video, graphics, and games. The agent works with your files and drives apps like Blender, DaVinci Resolve, and Unity right on your desktop. Bring Opus, Astra, or DeepSeek. Excited to try this one.

    Continuous AI Brings Agentic Automation to Repository Workflows

    Tessl's blog post argues that repository automation needs Continuous AI, a third pillar alongside CI and CD for scheduled, auditable AI workflows that improve repositories over time. The article describes GitHub Agentic Workflows, which harden agentic workflow specifications into GitHub Actions that can run coding agents such as Claude Code, Copilot CLI, Gemini CLI, or Codex-style agents. It emphasizes read-only agent steps, restricted outputs, and human review of pull requests.

    Goodfire deploys probe-based cyber monitors on Kimi K3 with a judge cascade

    Goodfire Research describes probe-based cyber monitors for Kimi K3 and GLM 5.3 deployed on a production inference stack. The probe filters suspicious exchanges before an LLM judge reviews them, reaching about 93% recall at a 5.5% benign-session interruption rate at roughly 50x lower judge cost. In FAR.AI's red-teaming, the monitor reduced universal jailbreaks to zero across 140 tested strategies.

    Open-source models absorb easier tasks, testing frontier labs' business case

    SemiAnalysis argues that many businesses, especially low-margin ones, are offloading simpler software and white-collar tasks to increasingly capable open-source models. It frames the durability of frontier labs as depending on whether new tasks enabled by smarter frontier intelligence will outgrow the work moved to cheaper models. The post asks whether an economy could absorb 100 million superintelligent PhD-level experts quickly while still earning high ROI.

    ReJev fine-tunes MiniCPM5-2B to lift decision accuracy to 80.50%

    ReJev, an independent community project, applied LoRA post-training to OpenBMB's MiniCPM5-2B for bounded agent decisions: state, question, and candidate options yield one choice. On its sealed 1,892-sample holdout, accuracy rose from 51.11% to 80.50% (+29.39 percentage points) with 0% invalid outputs, at about $5.31 in cumulative Modal billing including earlier experimental overhead. The authors describe this as an early, task-specific result, not parity with Jev.

    We urgently need more public traces of AI agents attacking and defending systems. Defenders can’t learn from what they can’t see. If you have traces and are being pressured to keep them private, my DMs are open. Let’s level the playing field and fight the asymmetry and lack of transparency in AI!

    The South Korean bank hack fits with this. Yes, open models are being fitted to be used by some attackers, but so long as Claude Code can be the orchestrator of a hack we desperately need open models to diffuse defense as well. A hard balance societally to stomach, but needed.

    IBM Builds Spyre as a Native PyTorch Device via torch-spyre

    IBM's torch-spyre integration makes Spyre, its dataflow inference accelerator, a native PyTorch device by mapping PyTorch's device, allocator, stream, and event abstractions onto the Spyre runtime and firmware. Tensors stay resident on device="spyre" between operations, and FX graphs remain in the Inductor compiler path. The approach gives eager and compiled execution one path with lower launch overhead.

    JetBrains releases Mellum2.1, an open coding model trained with reinforcement learning

    JetBrains released Mellum2.1, a 12B mixture-of-experts model with 2.5B active parameters under the Apache 2.0 license, built for coding agents. Post-training shifted to reinforcement learning across thousands of environments and millions of sandboxed runs, and the model is available on Hugging Face. The source reports gains over Mellum2 on LiveCodeBench, AIME, GPQA Diamond, BFCL v4, IFEval, and SWE-bench Verified, and says it serves almost twice the tokens of Qwen3.5-9B under heavy load.

    Why it matters: The post shows how reinforcement learning in real sandboxed environments changed a compact open model's repository work, with benchmark gains against Mellum2 and two peers.
