Routing for long-horizon coding agents is a big deal.
@notdiamond_ai just announced a model router that works natively with Claude Code. This is huge.
It picks the model and reasoning effort before each turn in a session, runs through a privacy-preserving local proxy, and your requests still execute through your own gateway.
In their benchmarks, it approximates Opus 4.8 Xhigh quality at 39 to 61 percent lower cost.
