This week in open-source AI: Xiaomi's MiMo-V2.6-Pro tops the open-weights leaderboard at roughly 1/45th the cost of Opus 5; NASA and IBM released the Lunar Foundation Model, one of the first open models for lunar science, trained on 2M image tiles; and EvoSkill has drawn 60+ citations from MIT, Google, and others. The newsletter's thesis: frontier labs may want to pace the frontier, but open-source AI keeps closing in on cost-efficiency.
