K2 0905 and K2 Thinking shortly after that have done impressively well in my personal use cases and was severely slept on. Faster, more accurate, less expensive, more flexible in terms of hosting and available months before Gemini 3 Flash, I really struggle to understand why Flash got such positive attention at launch.

Interested in the dedicated Agent and Agent Swarm releases, especially in how that could affect third party hosting of the models.

K2 thinking didn't have vision which was a big drawback for my projects.
