## The use case: how Harvey deploys Baseten

Harvey worked with Baseten Research to build a pipeline that post-trains an open-weight 27B model on its Legal Agent Benchmark with a long-horizon legal-agent harness in the loop. Baseten also developed STILL, a technique for compressing the KV cache, as a less lossy alternative to text-based compaction for long legal matters.

> In collaboration with Baseten Research, we built a pipeline that takes LAB signal, pairs it with a legal-agent harness designed for long-horizon legal work, and post-trains an open-weight model with that harness in the loop.
