Open-source momentum is picking up again, with multiple frontier labs releasing competitive models.
The quoted post highlights Kimi K3’s open-weight release on Monday and says other labs around the world are shipping strong open models, including Thinking Machine, poolside, Motif, and Upstage.
It also notes that closed-source labs are pushing ahead too, citing Opus 5, GPT-5.6 Sol, and Grok 4.5 as examples of the fast-moving frontier on reasoning quality, efficiency, and cost.
