Cooper jet, 280B-MoE in production, and the autonomous-lab pilot

Aether hit 3.6% mean Nu error on the Cooper impinging-jet benchmark — a third tighter than the next-best baseline. The 280B sparse-MoE checkpoint is in production. We launched the first autonomous-lab pilot.

01 · Research progress

Cooper impinging-jet Nu mean error at 3.6% — a third tighter than the next-best baseline. The 280B sparse-MoE checkpoint shipped to production. First autonomous-lab pilot launched at a biotech customer.

02 · Customer wins

Biotech customer running closed-loop discovery campaigns against an internal target panel. Active-learning loop closes weekly; plate-ready hits returned in three rounds.

03 · Model-card diffs

No refusal-corpus changes this month. Memory store quota raised on the Pro tier from 50 GB to 100 GB.

04 · An open question
