Summary
This weekly AI roundup from the AI Search channel covers a dense wave of major model releases. The headline story is the reveal that the mysterious stealth model “Ox Alpha” is actually GLM 5.3 Flash from ZAI — one of the best open-source models currently available, achieving a 20% hallucination rate on a key benchmark compared to 60% for Claude Opus and 80-90% for GPT models. ZAI simultaneously released the full GLM 5.3 weights at 753 billion parameters (756 GB), with Unsloth community quantizations bringing the 1-bit version down to 217 GB. A particularly significant development: GLM 5.3 Flash is being served entirely on Chinese AI chips, demonstrating that leading Chinese labs are no longer constrained by access to NVIDIA hardware.
Other major open-source releases covered include Tencent’s Hy4, Alibaba’s Qwen 3.8 Flash Next (described as near-frontier performance), and an updated Minimax video generation model with real-time generation capabilities. The humanoid robot games produced both world-record results and widely shared footage. Google DeepMind released a geospatial prediction model for disease risk and food security mapping, a new video generator, and a transcription model.
On the 3D generation front, the episode covers Block3D (generating 3D objects over five times faster than autoregressive methods at roughly 5 seconds per model), a video-to-3D world converter combining Qwen3VL, SAM 3, and Flux 2, and a Gaussian splat cleanup system using a pre-trained video model to repair degraded 3D renders.
