# lighteternal/biodecision-tev1-4b

Together AI's Tev1 recipe: the model is trained to emit only the letter of the correct option (loss on the letter and end-of-turn token), which makes the letter distribution the answer distribution. Dense, 4.7B params. Context: 256K tokens (config). License: research-only. Vendor-reported: "Clinical-trial outcome forecasting (CT Open Endpoint): 72.6 and 62.0 macro-F1, on par with or above GPT-5, o3-mini and Claude Opus 4.5."
