This month, we’ve continued to make Harvey smarter, more customizable, and easier to use. From major model upgrades to small but mighty workflow improvements, here’s what’s new.

Workspace customization, enhanced models, and improved knowledge management.

Create internal knowledge bases to curate and standardize your proprietary expertise—streamlining legal workflows and ensuring higher-quality, more consistent researching and drafting. 

We rolled out GPT-4.1 as the primary model powering Assist mode and Vault, improving baseline response quality, output length, and knowledge cutoff (May 2024 instead of October 2023). Draft mode has also been enhanced with a reasoning model, now delivering longer outputs, fewer hallucinations, better legal reasoning, and a more recent knowledge cutoff (May 2024 instead of October 2021).

Vault Review table outputs—which historically tended to favor English—now adapt to explicit prompt instructions, the language of your query, or configuration of your user profile.

Admins can now surface important information with pop-up notices and recurring workspace guidance, accessible via the left sidebar for easy access throughout the platform.

Design polish, quality-of-life improvements, and a smoother user experience across the board.

Assist mode now mirrors the agentic Assistant workflows UI with a cleaner chat-style layout, visible thinking states, and follow-up suggestions that persist in the thread.

Quickly pull in recently used and suggested knowledge sources when querying in Assist mode.

Search across threads, projects, and workflows from a new global search button in the sidebar. You can also jump straight into viewing or creating a new Vault project.

When setting up a Vault Review table, use the new filter button to narrow documents by classification type.

You can now quickly save documents from any Assistant thread into an existing or new Vault project.

See more content per cell in Vault Review tables by toggling on wrapped view—especially helpful for dense outputs.

If an upload to Vault fails, Harvey now shows a clear, consolidated error log so you can understand and resolve issues faster.
