Ornith 1.5 open models match Claude Opus 4.8 on coding benchmarks

An open-source model family just posted numbers that rival one of the most capable closed models in the world — and it's available under an MIT license. Ornith 1.5, released today by the Ornith AI team, is a three-model family spanning 9 billion dense parameters up to a 397 billion mixture-of-experts flagship. The big headline: the 397B MoE scores 86.1 on Terminal-Bench 2.1 (Terminus-2) and 86.0 on SWE-bench Verified, placing it on par with Claude Opus 4.8's 85.0 and 85.8 respectively.

Humanoid robot scores first autonomous full table-tennis match at Beijing conference

The 2026 World Robot Conference opened in Beijing on Monday with a milestone that puts embodied AI on the radar of anyone who follows the field: a humanoid robot completed the world's first fully autonomous table-tennis match — not a scripted rally, but a real game with serving, receiving, and adaptive shot selection against a human opponent. 超维动力 KAI (Chaoweidongli), a full-stack embodied AI company, demonstrated its SMASH 2.0 system on a standard ping-pong table at the Beijing Yichuang…

Deep Dive — The safety compute tax: OpenAI's 20% overhead and the price of alignment

OpenAI disclosed this week that monitoring its models for dangerous behavior will consume 20 percent of the compute it would otherwise use for inference — and the company says it will eat the cost rather than pass it to customers. The number sounds small. It is not. It is the first time a frontier lab has put a concrete price tag on alignment, and the timing tells you why it matters: the disclosure arrived in the same announcement where OpenAI confirmed it paused reinforcement learning on its…

NVIDIA Cosmos 3 — open-source world model for embodied AI

NVIDIA is betting that the future of robotics lives at the edge, not in the cloud. At the RSS 2026 conference in Sydney, the company's physical AI team laid out detailed technical specs for Cosmos 3 — a fully open-source world foundation model that unifies text, vision, audio, and action in a single Transformer architecture. Cosmos 3 replaces the fragmented patchwork of separate vision, language, and control models with one unified system.

AI 101 — What is synthetic data?

Synthetic data is information generated by a computer — not collected from the real world — that mimics the patterns, structure, and statistical properties of real data well enough to train an AI model. It is one of the most important tools in modern AI development, and one of the least understood. Every major lab is using it, many products depend on it, and the debate over whether it is good enough to replace real-world data is shaping where the field goes next. Why it matters right…

xAI multimodal lead joins Tencent's Hunyuan model team

xAI's multimodal understanding lead has decamped for Tencent, signaling a fresh push in China's race to build competitive vision-language models. The move is the latest in a pattern of senior AI researchers crossing between Western labs and Chinese tech giants — and it lands at a moment when multimodal capability is becoming the differentiator for both consumer products and enterprise agents. Lin Xudong, who led multimodal understanding at xAI and contributed to Google DeepMind's Gemini…
