The most powerful AI platform for enterprises. Customize, fine-tune, and deploy AI assistants, autonomous agents, and multimodal AI with open models.
Here are 5 factors that make a bigger difference to software development outcomes than “A.I.” coding assistants, but teams don’t address because they’re “old news, gra…
By Terts Diepraam We are working on an embedded scripting language for Rust. This language, called Roto, aims to be a simple yet fast and reliable scripting language for Rust applications. The need for Roto comes from Rotonda, our BGP engine written in Rust. Mature BGP applications usually feature some
