AIGoogle's Project Suncatcher will launch a prototype satellite on the Transporter-18 rideshare mission with SpaceX to test how its TPUs handle spaceflight. Initial ground tests showed the Trillium TPUs survived vibration and a radiation dose greater than a five-year space mission would deliver. Google says cooling with heat pipes and radiators and laser links between satellites in 2027 remain open engineering challenges.

Why it matters: The source reports concrete radiation, vibration, and cooling test results for TPUs, showing what space-based AI compute still has to solve.

AIARC Prize reports that the top Kaggle entry reached 24% on the ARC-AGI-2 private dataset at $0.20 per task, and that all winning solutions and papers are open source. The top verified commercial model, Opus 4.5 (Thinking, 64k), scored 37.6% at $2.20 per task, while a Poetiq refinement on Gemini 3 Pro reached 54% at $30 per task. The author argues that refinement loops are the main driver of 2025 progress, and says ARC-AGI-3 is planned for early 2026.

Why it matters: The post links 2025 competition results to a broader argument about refinement loops, showing how benchmark outcomes are being read as evidence of AI reasoning progress.
