Big fan of Codeium here. They're the only player who took vim/neovim users seriously from the start, and it's great to see people building extensions like monkoose/neocodeium. Their models or ux may not always be the best available, but their understanding of their target market and their product positioning is peak IMO, particularly the enterprise/on-prem options you mentioned. My money's on them long-term.
