### Articles

- [110 Humanoid Robots Danced for 5 Minutes Without a Miss. The Hard Part Was Consistency](https://hhfa008.github.io/ai-resources/blog/agibot-110-humanoid-robots-guinness-record.html): AgiBot ran 110 Expedition A3 units through a 5:43 routine with no reported failure. The record is verified; the claim that these were production units is the part to watch.
- [Qiyuan Built 5,000 Personal Robots in a Month. That Is Capacity, Not Demand](https://hhfa008.github.io/ai-resources/blog/qiyuan-robot-5000-units-one-month.html): One month after its Q1 and T1 launch, Qiyuan says unit 5,000 is off the line and daily capacity is above 200. The missing numbers are sell-through, returns and retention.
- [The UK Put OpenAI and Anthropic Inside a National Biosecurity Lab](https://hhfa008.github.io/ai-resources/blog/uk-ai-biosecurity-lab.html): A new independent non-profit gets £100m from government and up to £100m each from two frontier labs. Operating details are still missing.
