The score comes from our model.

• Show HN: Decision Studio – LM Studio for open-source, Jev-style decision models · score 8.3

  Bud Decision Studio is a desktop application for running open-source decision models locally, similar to LM Studio but for Jev-style 'System One' models. It provides a playground, template management, evaluation, history, API server, and on-device training with LoRA, all accessible through a polished GUI and CLI.

• Show HN: Homi, open decision model for audio, near Flash on MMSU and 50x cheaper · score 7.8

  Homi is an open decision model for audio that answers typed questions (yes/no, multiple-choice, scored levels) about audio clips, using a Qwen3-Omni-based architecture with a decision head instead of text generation. It claims strong performance on VocalGrad and MMSU benchmarks at significantly lower cost than Gemini Flash, with a fully reproducible training and evaluation pipeline.

• Show HN: BeelineBench – How well do decision models solve multi-step problems? · score 7.5

  BeelineBench is a benchmark for evaluating how efficiently decision models solve multi-step planning problems by scoring how directly they navigate to a solution. It uses a best-first search harness across seven domains (e.g., sliding puzzles, Blocksworld, Wikipedia navigation) and compares model performance against classic heuristics, random choice, and an oracle. The project is well-documented, configurable, and integrates with custom model APIs, making it a valuable tool for AI planning research.

• Show HN: THX-01 – Open- source decision model that runs on phones and beats Jev · score 7.3

  THX-01 is a 322M parameter non-autoregressive decision model that answers typed questions (choice, number, excerpt, citation) over documents in a single forward pass with calibrated probabilities. It uses reinforcement learning with a strictly proper scoring rule to ensure honest confidence, enabling selective automation. Benchmarks show it matches or beats larger LLMs on classification and extraction tasks while running in ~10ms on one GPU.
