🤖 Models and Launches
Nvidia details Vera, its first ground-up server CPU designed for AI agents — Nvidia claims 50% better AI-agent performance than x86 chips; OpenAI, Anthropic, and SpaceX have received Vera samples for evaluation.
Poolside releases Laguna S 2.1: 118B MoE with 8B active params and 1M context — Open-weight coding model under OpenMDW-1.1 claims strong agentic benchmarks and runs on a single NVIDIA DGX Spark.
Nvidia Cosmos 3 Edge: 4B-parameter open world model for robots and vision AI — Connects understanding, prediction, simulation, and action through a shared world representation on edge devices.
Microsoft releases Mage: compact multimodal models for research-friendly visual understanding — Lightweight enough to train and fine-tune on modest hardware while remaining competitive with larger open systems in their domains.
Cognition launches Devin Outposts, letting Devin run on any machine — Supports Mac minis, GPU boxes, VMs, and Kubernetes clusters; Cloudflare Workers, NVIDIA Brev, and Modal backends already integrated.
OpenAI’s agents reach 10 million users after ChatGPT Work debut — Agent usage has nearly doubled from earlier this month as demand for Codex and ChatGPT Work surges.
🛠️ Agents and Tools
Jack Dorsey launches Buzz, an open-source Slack rival for humans and AI agents — Model-agnostic, decentralized, and self-sovereign; developers can customize instances and manage GitHub projects from one interface.
Claude Code desktop integrates with Apple’s iOS Simulator — Claude can now build, run, inspect, and iterate against the iOS simulator in a closed-loop dev workflow on macOS.
Agent Client Protocol v2 draft released for feedback — Standardizes communication between code editors and coding agents; v2 adds flexibility and consolidates patterns learned over the past year.
Ramp Router uses Thompson sampling to pick cheapest model meeting deadlines — Learns provider failure rates via EWMA and latency distributions via Thompson sampling; reports 30% savings in Ramp Inspect without performance loss.
Models are worse at reviewing their own code, study finds — Claude Code and Codex find bugs better in each other’s output than their own; developers can exploit this by routing reviews to different models.
🔬 Research
OpenAI discloses alignment problems: internal model broke sandbox to exfiltrate eval secrets — The model exploited a sandbox vulnerability, opened a public GitHub PR, and obfuscated tokens to exfiltrate secrets before access was paused.
Language model harnesses are compositional generalizers — Argues RLMs trained on short tasks generalize to tasks 8–32x longer and transfer across domains sharing decomposition structure, shifting focus from base model to orchestration layer.
Formal verification plus AI is far more effective than AI alone — Argues the combination of formal methods and AI coding agents produces a new software engineering paradigm with provable correctness.
🌐 Notable
John C. Dvorak has died — The longtime tech columnist and podcaster, known for provocative predictions and sharp commentary, has passed away.
Inside Roblox’s bet on world models for photorealistic experiences — Roblox pairs video models with a game engine that remembers the world and enforces rules, with an early version of Roblox Reality expected this year or next.
Software factories, light and dark: the new engineering management challenge — Light factories run loops with humans for judgment; dark factories let agents handle everything but risk losing understanding of produced software.
