ModernBERT-large encoder (421M total) with a from-scratch decision head: option markers scored at their own MASK token, softmaxed per question. Answer schema is defined at request time, so new question types need no retraining. Three checkpoints routed automatically: English (512 ctx), multilingual mmBERT 322M (1024 ctx, 100+ languages), typed-decisions (1024 ctx). RLCD training. 33ms single-question answers on a T4.

Fit tiers use the same will-it-run logic as the rig finder. For comfortable fits, the badge reflects decode speed: fast >=20 t/s, ok 8-20 t/s, slow <8 t/s. t/s is a bandwidth estimate, not a measured benchmark.
PRICE HISTORY
Inference cost over time
Data accumulates from the first daily sync - longer ranges populate over time. Prices come from OpenRouter snapshots, not a historical API.
