AI leaderboard maker LMArena hits $1.7 billion valuation

If you want to know who’s up and who’s down in the AI model world, look no further than LMArena’s leaderboard. The startup has just raised a $150 million series A fundraising round, with a valuation of $1.7 billion.

In seven months, LMArena has raised $250 million, according to TechCrunch.

The leaderboard started as a research project by cofounders Anastasios Angelopoulos and Wei-Lin Chiang when they were graduate students at UC Berkeley.

The public leaderboard — formerly known as “Chatbot Arena” — shows the results of human evaluations of AI models for various tasks. Users can rate which model did a better job on one task in a sort of blind taste test.

The leaderboard is a hotly contested proving grounds for new models, and the company occupies a powerful position in an industry that lacks independent, industry-standard evaluations.
