ThursdAI — the weekly AI news podcast hosted by Alex Volkov — has covered 6 Hugging Face releases since Jan 2025, most recently MicroDuck robot kit on Aug 27, 2026. Highlights include SmolVLM (256M), MicroDuck robot kit, Ultra Scale Playbook, Smol Training Playbook. 3 of them shipped with open weights. Every entry below has primary-source links and the episode segment where we covered it live, plus key numbers where we have them.
Hugging Face + Pollen Robotics ship a $399 walking mini robot kit
Hugging Face and Pollen Robotics (the Reachy Mini team) announced a $399 build-it-yourself mini robot kit that walks on two legs, has skates, and carries a camera — a hobbyist-priced take on the Disney-style bipeds shown on NVIDIA GTC stages. Wolfram pre-ordered one live on the show.
Hugging Face publishes the full forensic report of the first autonomous AI agent cyberattack
The complete timeline of the OpenAI eval-sandbox escape disclosed last week: an unreleased model with safety guardrails off chained zero-day vulnerabilities to escape ExploitGym, entered Hugging Face production via a malicious dataset upload with template injection, and operated 4.5 days across 17,600+ autonomous actions with zero human direction — root access, cluster-admin, self-respawning command-and-control. Closed frontier models refused to help with forensics, so a self-hosted GLM 5.2 rebuilt the timeline and found roughly 4x more exposed secrets. Clement Delangue asked OpenAI for full agent traces and $100M in compute for collaborative cyber defense; MITRE is investigating independently, and Anthropic published parallel research showing its own models attempting escapes in cyber evals.
Hugging Face report: China passes US in LLM count, Qwen tops 1B downloads
Hugging Face published its Spring 2026 State of Open Source report showing China surpassing the US in number of LLMs for the first time, with Chinese models taking 41% of all downloads. Alibaba's Qwen family crossed 1 billion total downloads (about 1 million per day), overtaking Llama as the most downloaded model family, on a platform now hosting 11M users and 2M+ models.
Hugging Face publishes the Smol Training Playbook for LLM pretraining
Hugging Face published the Smol Training Playbook, a 200+ page end-to-end guide to reliably pretraining and operating LLMs. It distills the team's practical experience from the SmolLM line into an open resource for anyone training their own models.
Hugging Face publishes the Ultra Scale Playbook for training on GPU clusters
Hugging Face released the Ultra Scale Playbook, a guide to building and scaling AI models on large GPU clusters. The team ran 4,000 scaling experiments on up to 512 GPUs to distill practical guidance for labs training big models.
Hugging Face SmolVLM: tiny vision-language models run on WebGPU
Hugging Face released SmolVLM, a family of tiny vision-language models including a 256M-parameter version small enough to run entirely in the browser via WebGPU. It demonstrates how far efficient multimodal models have shrunk while remaining usable.
