Harvey’s shaking things up, integrating Anthropic and Google’s models right alongside OpenAI. It’s a bold move in the legal AI world, where Harvey still leans on OpenAI as a core player but isn’t ditching it entirely. Anthropic’s Claude series and Google’s smarts now handle tasks like legal drafting and compliance, tailored for lawyers buried in paperwork. This level of customization mirrors advancements in AI-powered personalization seen in other industries like email marketing.

Harvey’s boldly blending Anthropic and Google’s AI with OpenAI, shaking up legal drafting and compliance for swamped lawyers.

Oh, and funding? Google’s GV threw in for Harvey’s $100 million Series C back in 2024, which reeks of strategic favoritism. Hybrid clouds keep things flexible, bouncing between Anthropic’s setup and Google Cloud.

This shift screams market expansion. Harvey just snagged a $300 million Series D in early 2025, pushing its valuation to $3 billion. Investors like GV and Sequoia are all about dodging vendor lock-in, so Harvey’s multi-model approach boosts accuracy and customization.

Imagine this: lawyers picking models per task, like Claude for research or GPT-4.1 for drafting. It’s not just tech; it’s smarter workflows, with updates to May 2024 knowledge cutoffs making outputs more relevant. Vault tools even adapt to languages and user quirks, cutting down on AI blunders.

Financially, this diversification might ease OpenAI’s pricing grip, thanks to Google Cloud’s backbone. Users get perks like longer drafts and better response quality, reducing those pesky hallucinations.

Harvey’s not just playing; it’s leading, as an OpenAI alum now eyeing rivals. Sarcastic? Sure, but in this cutthroat scene, who wouldn’t hedge bets? The platform’s audit-ready, cross-checking outputs for reliability.

All in all, Harvey’s evolution? It’s messy, innovative, and hey, about time. To guide this transition, Harvey employs BigLaw benchmark for evaluating model performance on legal tasks. This progress is evident as seven models now outperform the originally benchmarked Harvey system on BigLaw Bench within a year. Blunt truth: in legal tech, loyalty’s overrated when the competition’s this fierce.
