Harvey is a legal AI company that builds generative AI tools for law firms and corporate legal departments, backed by investors including OpenAI.
Kirkland & Ellis agreed this year to pay Palantir $500 million to build technology for its private equity fundraising advice, Business Insider reported. With Harvey saying it has users at 80% of the largest 100 firms, one consultant says the edge has to come from what the models know.

Z.ai launched GLM Legal to cut hallucinated citations in legal work, but it published no accuracy figures anyone can verify independently. Teams weighing it against Harvey or CoCounsel will have to build their own citation test, because no public number supports the comparison.

About one in five UK and Irish law firms that have widely adopted AI report difficulty meeting billable-hour targets, legal software company Clio found. Firms must now decide who keeps the hours AI saves, and who pays to train juniors once software does the document review.

OpenAI's GPT-6 Astra scored 99.9% on ARC-AGI-3 through a proprietary harness but 62.7% on the benchmark's neutral one, Live Science reported. Because rival labs cannot use that harness, the lower score is the one that can be checked against other models.

Venture-backed AI companies bought 195 AI startups through Sept. 29, Crunchbase data shows, 14% more than all of 2025, while buyers rose just 2%. The same companies are buying more often, so sellers face a pool of acquirers that has barely grown.

Clio, last valued at $5 billion, has bought Learned Hand, a startup that builds AI tools for judges, on undisclosed terms. Jack Newton is betting that litigants without lawyers will push courts toward AI, and that the bench can lead Clio to Big Law.

Tenet is post-trained on Moonshot's Kimi K3, converting per-call payments to OpenAI, Anthropic and Google into a fixed training bill. The counterparty risk moved rather than disappeared.

Lightspeed and Diffusion co-led $550m at a $15.6bn mark, which added $4.6bn of paper value in six months and only reads as ordinary software if $400m of ARR becomes about $1.56bn. Eighty of the Am Law 100 already buy.

Astra for Law is GPT-6 Astra with a legal search index and analysis instructions wrapped around it. OpenAI will also sell that index through an API to Harvey and Legora, at a price it has not published.

Claude Marketplace groups connectors, partner products and consultants in one catalog, and eligible customers can direct part of an existing Anthropic commitment at the software listed there.

Lenny's newsletter counted eval experience in nearly half of 25 product manager postings it listed, and the two practitioners it commissioned say most teams skip error discovery and write metrics for failures they never found.

Max Junestrand told Politico that Europe's opportunity is in applications, and in the same conversation he agreed that European customers waiting longer for new American models is a competitive disadvantage.

A March 2026 update lifted usage and inverted Harvey's gross margin, from about 50% to minus 50%. Its answer is Tenet, a legal model post-trained on the open-weight Kimi K3 base and run on compute it controls.
Reality
The legal toolkit ships as its own entry in the ChatGPT model picker and its own API string. Firms weighing it against retrieval stacks they already built still have no price to compare.
