Note on this row
Typecastlm[server] 1.1.2 (wheel identical to git e95911e), checkpoint mihailgribov/typecastlm-qwen3.5-3.8b rev dcfecfdc28e44ef82631901628535b71574e27af: frozen Qwen/Qwen3.5-4B blocks 0-27 plus a computed 39-row head, one forward pass, four calibration temperatures by question type; transformers 5.3.0, flash-linear-attention 0.5.2. States over 32,768 tokens are folded in the middle, not refused. The server reads a noul question's meaning from the order of its two criteria (first = true), not from their keys. Offline self-hosted inference of all 842 decisions (534 frozen v1.2 + 308 sealed v1.4) in a network-disabled, read-only container on an evaluator-owned Lium RTX PRO 6000 Blackwell 96 GB pod, through JevBench's unchanged typesafe adapter against the author's own server on loopback; no operator endpoint; no golds were exposed. Latency is the serial request wall time on the standard+judge items with the self-hosted adjustment. Cost is a labelled estimate: DeepInfra Qwen/Qwen3.5-4B list price $0.03/M input (the exact base weights; one pass, no output), read 2026-09-24, over the server's own usage.input_tokens; it is not a GPU bill.
