We partnered with @FireworksAI_HQ to train open-source models for legal. Here's what we found:

1) Hybrid legal agents can beat frontier models on quality and cost by routing selectively to a frontier advisor.

We tested a hybrid setup where GLM 5.1 served as the primary worker, routing tasks to Opus 4.7 as an advisor when needed.

GLM invoked Opus sparingly, just 0.83 times per task on average.

The hybrid setup beat Opus on both quality and cost: 18% all-pass vs 14%, at $368 vs $954 across the same 100 tasks.

2) Post-training can push open models to frontier-level legal performance.

On a 100-task slice of our Legal Agent Benchmark (LAB), SFT moved Kimi 2.6's all-pass rate from 11% to 15%, beating Opus' 14%.

But the cost gap was even more striking: $84 vs $954 across the same 100 tasks, or ~11x cheaper.

We're excited to continue working with @FireworksAI_HQ on the next generation of open-source legal agents.

The best legal teams aren't using AI to replace lawyers’ time.

They're using AI to reclaim it for judgment, strategy, and collaboration.

AI agents run the workflows. Lawyers drive the outcomes. Harvey is the platform where both happen.

Today we announced new funding led by GIC and Sequoia to scale the agents our customers run on Harvey and expand the legal engineering teams that help them turn expertise into systems.

We're partnering with @trajectorylabs to bring sovereign continual learning to legal AI with NVIDIA Nemotron models.

Continual learning allows agents to improve over time from feedback on their work: every redline refines the next draft.

Open-weight models offer full auditability and data sovereignty over legal agents.

Using Trajectory's platform, we post-trained NVIDIA Nemotron 3 Super on our Legal Agent Benchmark (LAB), measuring performance on 1,200+ complex end-to-end legal tasks across 24 practice areas.

Initial results show that a post-trained Nemotron 3 Super can match performance of closed-source frontier models.

This is just the start: we'll keep pushing the frontier with the more powerful Nemotron 3 Ultra when available.

We partnered with @trajectorylabs to post-train NVIDIA Nemotron 3 Ultra for legal. Here’s what we found:

1) Open-weight models can reach frontier legal performance.

On our Legal Agent Benchmark (LAB), Nemotron 3 Ultra started at a 0% all-pass rate. After post-training, it reached 5.8%, placing it between Sonnet 4.6 at 4.2% and Opus 4.6 at 6.6%.

2) Post-training dramatically improves reliability.

Before training, many held-out tasks missed enough rubric dimensions to land around ~70% pass rates. After training, those tasks shifted toward ~95% pass rates.

3) Open-weight performance comes at much lower cost.

Post-trained Nemotron 3 Ultra reached a similar quality band to leading closed models while running at roughly 1/8th to 1/50th the per-token price of Sonnet 4.6 and Opus 4.6.

Most importantly: we post-trained this model on the @trajectorylabs platform less than 24 hours after Nemotron 3 Ultra launched, using the same harness, data, and recipe we used for Nemotron 3 Super.

More to come as we continue to experiment with open-weight legal agents.
