I'm Dave, an AI dev in Toronto.

Building LoopGain, an open-source tool that measures when an agentic loop has stopped improving (loop gain / Aβ, borrowed from control theory) and stops it there instead of burning credits to max_iterations. Stops at convergence, rolls back on divergence.

loopgain.ai

Happy to talk agents, control theory, or anything in between.
