To me the most interesting chart on artificial analysis is intelligence index vs cost per task. It's like the third chart down and they graph a pareto line showing where the frontier is and every model on the pareto line has been interesting to me. Luna, Mimo-v2.6-pro, Sol. Hell, Argon.
This MiniMax model is clustered with Haiku 5.5 so (combined with the criticism on here that it was lacklustre while free on opencode go) I don't find it interesting, but every announcement has a chance at pushing that frontier.
I was benchmarking affordable LLMs for japanese->english translation recently and the winner was Kimi K3 - there are a ton of interesting models in the wake of the flagships.
