Tech & Society:

• Labour and Lib Dem MPs demand ‘shameful’ Palantir NHS contract be scrapped — UK MPs call for Palantir’s NHS data contract to be cancelled, saying the spy-tech company should “have their hands ripped off our NHS.”
• Man used AI to make false statements to shut down London nightclub — A man pleaded guilty to using AI-generated fictitious complaints to try to shut down London’s Heaven club. Police say this is a growing issue.
• NAACP lawsuit accuses Elon Musk’s xAI of polluting Black neighborhoods near Memphis — The NAACP alleges xAI is illegally spewing toxic pollutants from its datacenters in predominantly Black Memphis neighborhoods.

🤖 Models & Releases

• Gemini 3.1 Flash TTS: The Next Generation of Expressive AI Speech — Google’s new TTS model supports 70+ languages with audio tags for granular vocal style control. Scores Elo 1,211 on the Artificial Analysis TTS leaderboard. All output watermarked with SynthID.
• Claude Opus 4.7 — Anthropic’s latest flagship. Biggest points-getter on HN today — details still trickling out but clearly a major capability jump.
• Qwen3.6-35B-A3B — Alibaba releases a sparse MoE model designed for agentic coding. 35B total params but only 3B active per forward pass — strong capability at minimal compute cost.
• Parcae: Doing More with Fewer Parameters Using Stable Looped Models — Together AI releases Parcae, a stable looped architecture that achieves Transformer-2x quality through recurrence rather than pure data scaling. Named after the Roman fates.
• Nucleus-Image: First Sparse MoE Diffusion Model — 17B parameter, 2B active sparse MoE diffusion model for images. Apache 2.0 with weights and training code released.

🛠️ Agents & Tools

• OpenAI’s Updated Agents SDK — OpenAI pushed its Agents SDK toward long-running, durable agents with primitives for file/computer use, skills, memory, compaction, and sandboxed execution. The harness is now open-source and customizable. Cloudflare, Modal, Daytona, E2b, and Vercel all announced sandbox integrations on day one.
• Cloudflare’s Agent Platform: Project Think, Browser Run, and Voice — Cloudflare had one of the busiest agent-infra release cycles: Project Think (durable execution, sub-agents, sandboxed code), Agent Lee (in-dashboard agent), real-time voice pipeline over WebSockets, and Browser Run (rebranded browser automation with Live View and session recordings).
• Humwork A2P Marketplace — First Agent-to-Person marketplace connecting AI agents with 1,000+ verified human experts for sub-30-second handoffs. 87% resolution rate. YC P26 batch.
• Cloudflare Email Service for Agents — Email infrastructure designed specifically for AI agents to send, receive, and manage email programmatically.

🔬 Research & Engineering

• Evaluating Agent Reasoning — IBM’s Vakra Benchmark — IBM Research uses an executable benchmark with thousands of APIs to test multi-step agent reasoning, revealing consistent performance gaps and common failure modes.
• Evaluating Agents for Scientific Discovery — AI2’s ScienceWorld and DiscoveryWorld benchmarks test whether AI agents can actually do science — from re-making elementary-level discoveries to open-ended PhD-level research.
• Why Do dLLMs Tend to Collapse in RL? — Diffusion Language Models collapse during RL training due to high-variance Monte Carlo sampling creating noisy importance ratios. The StableDRL framework fixes this with unconditional clipping and self-normalization.
• Rethinking AI TCO: Cost Per Token Is the Only Metric That Matters — NVIDIA argues cost per token is the real metric for AI infrastructure, showing Blackwell drastically reduces it vs. Hopper.
• Many-Tier Instruction Hierarchy in LLM Agents — Researchers propose ManyIH for instruction conflict resolution across 12 privilege levels. Current models score only 40% accuracy.
• NVIDIA Lyra 2: Camera-Controlled 3D-Consistent Video — Framework for generating long videos with camera control using geometry-guided retrieval to prevent spatial forgetting.

🏢 Industry & Business

• OpenAI Expands Codex to “Almost Everything” — Codex moves from code-only toward general-purpose software engineering. 553 points on HN.
• Snap Blames AI as It Lays Off 1,000 Workers — Snap cuts 16% of workforce (~1,000 jobs) citing AI efficiency gains. Stock under pressure from activist investor.
