27BReasoningby Baseten (Base Labs) Start a discussion

Baseten's 27B decision model released 2026-10-21 (MIT, a full fine-tune of Qwen3.5-27B with the vision encoder frozen). Give it a state and a set of questions and it returns a calibrated probability for every option from one shared-prefix prefill — cheaper and steadier than asking a general LLM question-by-question for routing, guardrail and classification work. Scores: #1 of 208 models on the Jev Decision Index 0.4 (71.24, ahead of Perplexity Decider v1.2 at 69.42) and #1 on a replica of the Artificial Analysis Decision Index (65.9). Full-attention layers use a block-bidirectional mask; max sequence length 16,384 tokens. Note: pipeline is text-classification and self-hosting requires the official setup.sh with the OneJev runtime (a single CUDA GPU) — this is not a general chat model.
