What it can run
The agent count is a memory estimate for this model and context. The speed check below is a separate estimate, not a measured rate per agent.
How it is calculated
How many agents of each open model fit in its memory at once, each with room for about 32 thousand tokens of conversation — a typical coding agent. The agents share one copy of the model, so the first one needs the most memory and each next adds only its own conversation. Our estimate from memory size; open a row to try other settings.

How the fit score is made
Each part compares this computer with the five others on the page: 100 is the best of them, 0 the weakest. The weight says how much the part counts.
