## Industry News
- **Vercel security breach impacts customer systems**: Unauthorized access to internal Vercel systems affected a limited subset of customers; users should rotate GitHub tokens, API keys, and environment variables immediately. [link](https://x.com/vercel/status/2045877685084197041)

- **Google releases A2UI v0.9 with AG-UI integration**: New version enables any AG-UI-compatible agent to stream generative UI to frontends on-the-fly, with 2x faster generation and support for React, Angular, Flutter, and Lit. [link](https://x.com/ataiiam/status/2045877624204148968)

- **Blue Origin achieves reusable rocket milestone**: Successfully launched New Glenn rocket and recovered booster, becoming the second company after SpaceX with reusable orbital-class launch capability. [link](https://x.com/johnennis/status/2045878530852982989)

## Tips & Techniques
- **Claude 4.7 requires updated memory slots for optimal performance**: Users experiencing increased hallucinations should update Claude's memory slots; the model shows improved performance when memory is properly maintained. [link](https://x.com/AICEOGiuliano/status/2045850557978431592)

- **Always verify LLM optimization code step-by-step**: When asking ChatGPT to vectorize optimization code, it automatically makes diagonal/block-diagonal Hessian approximations even when told not to—increase complexity gradually and verify each step works.

- **Start optimization modeling with high-level languages first**: Generate GAMS or CVXPY code before implementation to check model correctness and debug constraints—LLMs can forget inequality constraints or simplify objectives during vectorization.

## New Tools & Releases
- **Worklayer launches remote skills for team agents**: Remote skills allow one person to codify a process that scales across all team members' agents, with automatic updates when changes are made—no manual syncing required. [link](https://x.com/trillhause_/status/2045878331615150315)

- **Qwen3.6-35B-A3B finetuned for agent workflows**: "Carnice edition" release optimized for Hermes-style agent tasks on uncensored data; described as a free, locally-runnable Claude Sonnet 4.5 equivalent. [link](https://x.com/ClementDelangue/status/2045874706373329171)

- **OpenMythos: Open-source theoretical reconstruction of Claude Mythos**: First-principles PyTorch implementation attempting to reconstruct Anthropic's advanced reasoning architecture using publicly available information. [link](https://x.com/KyeGomezB/status/2045877724372505018)

## Research & Papers
- **LuxDiT: Estimating HDR environment maps from images/video**: Open-source code and Gradio UI released for high-quality HDR environment map estimation from single images or video sequences. [link](https://x.com/RfLiang/status/2045873441593868763)

- **Cross-datacenter LLM inference now viable**: Kimi demonstrates prefill/decode disaggregation across datacenters with heterogeneous hardware, potentially unlocking idle compute capacity worldwide for large-scale inference. [link](https://x.com/Kimi_Moonshot/status/2045877016176587236)

- **ViPRA: Video prediction improves robot manipulation**: Accepted to ICLR 2026; using video prediction models for robot actions shows significant improvements in manipulation task success rates. [link](https://x.com/SandeepRoutra11/status/2045856581510720174)

- **Meta pre-training realities exposed**: Llama 3 training on 16,384 H100s experienced 419 failures over 54 days (average: one every 3 hours); MoE models achieved only 20-35% GPU utilization, and FP4 training remains theoretical. [link](https://x.com/grapeot/status/2045871971263726075)
