- Coding ability
- Reasoning capability
- Context window
- Cost
- Speed
Those metrics are useful.
But after spending enough time with autonomous agents, I’ve come to believe they don’t measure the thing I care about most.
Operational reliability. Continue reading Mimo 2.5 Didn’t Just Make Mistakes. It Changed How I Evaluate AI Models.
