Move over, DeepSeek. Seattle-based nonprofit AI lab Ai2 has released a benchmark-topping model called Tulu3-405B.

Ai2’s model, called Tulu 3 405B, also beats OpenAI’s GPT-4o on certain AI benchmarks, according to Ai2’s internal testing. Moreover, unlike GPT-4o (and even DeepSeek V3), Tulu 3 405B is open source, which means all of the components necessary to replicate it from scratch are freely available and permissively licensed.
