Best AI Models Tools

AI21 Labs is one of the original independent foundation-model labs, founded in Tel Aviv in 2017 alongside OpenAI and Anthropic. Where the headline race has been about raw frontier benchmarks, AI21's bet has been different: build models that are dramatically cheaper to serve, hold context longer, and ship with the compliance plumbing that regulated industries actually require — and sell the whole stack, not just an API. The flagship is the Jamba family — open-weight hybrid Mamba/Transformer mode
