TOD scores options for tasks such as ticket routing, intent classification, urgency and severity rating, using a 150M retriever to narrow more than 120 labels to a shortlist with recall@16 of 0.9–1.0 on the company's evals. The model supports up to 49k tokens of context and up to 8 images per request, and Parsec AI said it is working on RL environments for custom fine-tuning.", "body_md": "Hi HN, we built TOD, a model and API for jevlike LLM pipelines.\n\nwe have people using it for, routing a ticket, classifying intent, deciding whether something is urgent, or rating severity.\n\nArchitecture - 12B Gemma fine-tuned to score options. since it is gemma based it has multimodality built in - When there are >120 labels, we have a 150M retriever that narrows them to a shortlist (recall@16 is 0.9–1.0 on our evals), and the 12B model scores that shortlist. - Context goes up to 49k tokens, with up to 8 images per request.\n\nwe have open sourced it,\n\nmodel: [https://huggingface.co/parsecai/tod](https://huggingface.co/parsecai/tod)\nAPI: [https://parseclab.ai/tod](https://parseclab.ai/tod)\n\nWe are working on getting the RL environments to finetune for custom use cases.\n\nwould love to hear your opinions on this.\n\nComments URL: [https://news.ycombinator.com/item?id=49981275](https://news.ycombinator.com/item?id=49981275)\n\nPoints: 1\n\n# Comments: 0", "url": "https://wpnews.pro/news/show-hn-tod-a-universal-decision-model-based-on-task-oriented-design", "canonical_source": "https://parseclab.ai/tod/", "published_at": "2026-10-06 17:07:37+00:00", "updated_at": "2026-10-06 17:21:19.478832+00:00", "lang": "en", "topics": ["large-language-models", "ai-products", "ai-tools", "machine-learning", "developer-tools"], "entities": ["Parsec AI", "TOD", "Gemma", "Hugging Face"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/show-hn-tod-a-universal-decision-model-based-on-task-oriented-design", "markdown": "https://wpnews.pro/news/show-hn-tod-a-universal-decision-model-based-on-task-oriented-design.md", "text": "https://wpnews.pro/news/show-hn-tod-a-universal-decision-model-based-on-task-oriented-design.txt", "jsonld": "https://wpnews.pro/news/show-hn-tod-a-universal-decision-model-based-on-task-oriented-design.jsonld"}}
