decider-4b-tr-judge is an open-weight model for text classification from Hayri Yigit, released under other. It has 4.2B parameters and a 262,144-token context. At 16-bit it needs about 10.1 GB of GPU memory, which fits on 1x MI300X from $1.85 an hour, at the lowest prices in the SAVRN Index.

Model Card

English summary. A third LoRA round (rank 64, merged into the bf16 weights) on hayriyigit/decider-4b-tr-rag for a RAG relevance judge: does this retrieved document carry information that contributes directly to the answer, for the asked entity, institution, facet and period? Unlike the -rag model, partial evidence counts as relevant. The input is the production format: state {question, document, today} (in that order), the document rendered as [date] title + body (4000 characters), one fixed instruction. On held-out partial-evidence rows the "yes" rate goes from 0,028 to 0,952 (HotpotQA-tr) and 0,004 to 0,936 (synthetic); the cost is 2-8 points on some negatives (facet 1,000 → 0,920). Most…

Small, fast decisions for routing and checks at volume. Send text or JSON state with choice, noul (yes/no), or score questions. Get a probability for every offered answer, not generated text. Each batch takes one forward pass; large requests can use several batches. Use choice to route a request, noul for a yes/no check, or score for an ordered rating. The same call can ask several questions about a single state. Try it: POST /v1/systemone, GET /v1/models, and GET /healthz. Point TypeSafe's server-side Python or JavaScript SDKs at it with TYPESAFEBASEURL; text decisions use the same request and response fields as hosted Jev.

Kev-4B-MLX-Serve-8bit

Alin C Selea

Kev-4B (a LoRA on Qwen3.5-4B-Base with a pointer head) packed for mlx-serve's POST /v1/decisions. Kev answers typed questions about a piece of text (choice, noul, score) with calibrated probabilities. It never generates text. The pack folds the LoRA into the base the way kev does on MLX, quantizes the trunk to 8-bit (affine, group 64; a bf16 build comes from --q-bits 0), and stores the pointer head as kevhead.safetensors with the calibration temperature in kevconfig.json. No PyTorch or pickle file is needed to serve it. Built with tests/convertkevweights.py from the mlx-serve repo. Kev and Qwen3.5 are Apache-2.0.

uratori-ja-4b

Tokimoa

uratori-ja-4b is a Japanese decision model. Given a text state (for example a source document and a claim) and one or more typed questions, it returns a probability distribution over the allowed answers in a single forward pass, without generating text. Three question types are supported: noul (yes/no), choice (pick one of 2 to 8 labelled options) and score (an ordinal scale with 2 to 10 levels). It is trained for three jobs: checking whether a claim or an answer is supported by supplied evidence (grounding), comparing two documents (contradictions, meaning-changing edits, added claims) and judging retrieval results and answers in a RAG pipeline (relevance, sufficiency, faithfulness). The…
