Open-weights decision model built on Sarvam 105B. Given context and questions with fixed answer options, it returns a probability for each answer in one forward pass without generating text. It needs about 106 GB of disk and a B200/H200-class GPU.

Sarvam-Prism is a decision model from Sarvam AI, built on Sarvam-105B. The user supplies a context (state) and one or more questions, each with a fixed set of possible answers. The model returns a probability for every answer in a single forward pass. It does not generate text, so the result is always one of the supplied options.
Three question types are supported: choice (probabilities per option key), yes_no (probability of yes) and score (ordered levels, with an expected level index and per-level probabilities). All questions in a request are scored together, in batches, and each is scored independently. Use cases include ticket routing, urgency classification and sentiment scoring. The model card lists support for English and Indian languages including Hindi, Bengali, Tamil and Telugu. Sarvam reports a median latency of 44 ms per request on one NVIDIA B200.
The weights are released under Apache-2.0 and are about 106 GB. They are stored in a custom FP8 layout and must be loaded with the provided prism.py. They cannot be loaded with AutoModelForCausalLM or served by general-purpose inference servers. Self-hosting needs one FP8-capable GPU with about 120 GB of free memory, such as a B200 or H200. A hosted API is also available from Sarvam.
