Kilo's pitch leans on usage data showing developers reach for three or more model providers up to 70% of the time when balancing cost and performance, and it claims Anaconda's engineers have already migrated from Cursor.

Beam scored 80.9% on SWE-bench Verified, 90.5% on GPQA Diamond, and 78.7% on the MCP Atlas benchmark. The point is not any single score; it is that a credible open-weight coding model now ships with day-one inference infrastructure, adjustable reasoning effort, and agentic benchmark coverage.

Kilo is selling freedom from exactly that dependence, with a free year to make the switching math easy. Baseten and Reflection are making open weights a first-class, day-one option. NVIDIA is saying the machine under the desk can host more of the loop. This suggests the durable moat in developer tools is not the IDE, the keybindings, or even the agent UX — it is guaranteed, multi-source model supply with sane routing economics.
