Harvey and Fireworks AI have finished post‑training a Kimi K3 base model, creating a new model called Tenet. Tenet scores 19.7% all‑pass on the Legal Agent Benchmark, about twice the number of tasks completed and more than double the all‑pass rate of the original Kimi K3 (10.8%). The cost per task stays roughly the same at $5.92 versus $5.62 for the base model. The gains also show up on other legal agent tests the model never saw during training.
Why it matters
Law firms can run more complex AI‑assisted legal tasks without higher per‑task fees.
