    TLDR

    Not Diamond announced Not Diamond Code, an intelligent model router for long-horizon coding agents. The system switches models at each step based on predicted future performance. Not Diamond states the router reduces inference costs by 20% or more without degrading overall task quality. It integrates with existing gateways and harnesses including Claude Code. Investors and creators such as Matthew Berman, Scott Belsky, and Julien Chaumond posted support for the launch. Rohan Paul noted the routing layer enables dynamic model selection during agent sessions. The announcement appeared in posts linking to the company blog.

    @julien_cModel routing is the missing layer of the multi-model stack. open models keep getting better at coding, routing helps them deliver the most value possible. congrats to the not diamond team. exciting results!
    @mckaywrigleybullish model routers. same perf at lower cost is obvious. but there are massive gains to be had by creating "smoother" intelligence via blending multiple jagged models together. the era of model melding begins.
    @scottbelskythere are hundreds of decisions per session that no developer wants to make… Been inspiring to watch the Not Diamond team craft a world-class model agnostic router for long-horizon agents, launching today
    @MatthewBermanModel routing in any harness, including Claude Code. Not Diamond is an incredible team, I'm proud to be an investor.
    @rohanpaul_aiSo much brilliant work is coming on the routing layer of inference. Not Diamond just announced Not Diamond Code, a routing layer that lets a coding agent switch between models at every step. claims this cuts costs by 20% or more without reducing overall task quality. The point is long-horizon coding makes model routing much harder than picking the cheapest model for each prompt. A cheap model may handle the current turn, but switching to it can discard a warm KV cache or leave later steps with weaker context. Not Diamond Code instead predicts the future cost and reward of each model and reasoning-effort choice across the remaining agent trajectory. e.g. the below graph is taken from their official blog, show that how different models are better at different parts of a coding task, and a router that can choose among them can outperform an Anthropic-only strategy while spending less. In this benchmark, the mixed router improved performance by 3.6% and increased savings from 39% to 66%.
