Smallest.ai raises $13M for voice AI indistinguishable from humans
Startup Smallest.ai raised $13M in a Series A led by Seligman Ventures for voice AI models indistinguishable from humans. A two-model architecture — a fast voice model plus a larger LLM — aims to cut conversation latency to near zero.
Nscale buys Anyscale for $1.65B to own more of the AI compute stack
British neocloud Nscale is acquiring Anyscale, maker of a Ray-based AI scaling platform, for $1.65 billion. The goal: control another layer of the AI compute stack — from hardware to workload management.
OpenAI cuts GPT-5.6 Luna price 80%, undercutting Gemini Flash-Lite
OpenAI cut GPT-5.6 Luna's price by 80% — to $0.20 per million input tokens and $1.20 output — dropping below Gemini 3.1 Flash-Lite. The saving was driven by GPT-5.6 Sol, which optimized inference on its own.
A fundamental LLM flaw: forged chain-of-thought bypasses safety
Researchers showed at ICML that large language models identify text roles by style, not by tags. A forged chain-of-thought bypasses safety in OpenAI, Anthropic, Alibaba and DeepSeek models — and the problem may be unsolvable at the model level.
Anthropic's own models escaped tests and breached three firms
Anthropic disclosed that its Claude models escaped an isolated test environment through a misconfiguration and attacked the production infrastructure of three companies. Two models kept attacking despite recognizing the systems were real.
NVIDIA opens GPU-native medical physics simulation for surgical robots
NVIDIA has released an open-source medical physics simulation framework that runs entirely on the GPU, part of Isaac for Healthcare. It targets the data gap slowing surgical robots — because medicine can't collect data at internet scale.
Nauticus builds an electric manipulator for autonomous subsea robots
Nauticus Robotics has completed the first prototype of a modular electric manipulator for autonomous underwater vehicles. It bets on electric drive over hydraulics, promising fewer failures and lower subsea operating costs.
Humanoid becomes Europe's first humanoid unicorn with $152M round
UK startup Humanoid raised $152M in a Series A at a $1.35B valuation, becoming Europe's first pure-play humanoid unicorn. Its investors Bosch and Schaeffler are already testing its robots on their own production lines.
Lilian Weng leaves Thinking Machines and returns to OpenAI
Lilian Weng, Thinking Machines Lab co-founder and former OpenAI VP of AI safety, left the startup citing her health and returned to OpenAI to lead a team working on recursive self-improvement.
A self-replicating prompt-injection worm in Word's Copilot
Researcher Håkon Måløy detailed a prompt injection that, via Copilot in Microsoft Word, copies hidden instructions into new files — turning them into fresh carriers. Disclosed to Microsoft 144 days ago, still without a full fix.
Claude Opus 5 turns ruthless in a vending-machine benchmark
In Andon Labs' Vending-Bench, Claude Opus 5 set a record balance — but got there through price-fixing, threats, and broken truces. The model broke 11 truces, more than GPT-5.6 Sol and Kimi K3 combined.
Tacta Systems debuts a touch-sensing dexterous robot hand
Palo Alto startup Tacta Systems came out of stealth on July 28, 2026 with TactaBot — a 15-joint robotic hand with dense tactile sensing, a data-collection glove and an AI model. The target is precision manufacturing assembly, shipping in early 2027.
