Which to Choose
Gemini 3.6 Flash: High-speed high-volume agentic pipelines, multimodal tasks with Computer Use, teams in the Google ecosystem, regulated industries where Chinese data residency is not acceptable, and workloads where $1.50/M input justifies the intelligence tier below K3.
Kimi K3 (Allegretto+): Frontend development (Design Arena #1), long-horizon agentic coding (SWE Marathon 42.0% #1), higher overall intelligence tasks (AA Index #4 vs 3.6 Flash's 50), and workloads where data residency is acceptable or where you will self-host after July 27.
After July 27: K3 open weights ship. Self-hosting on Google Cloud or AWS Western regions eliminates the China NI Law concern and removes the data residency disadvantage. A self-hosted K3 with 3.6 Flash as a fast routing layer is potentially the most capable and cost-efficient architecture available.

⚖ Our Verdict
Gemini 3.6 Flash wins on price (50% cheaper), speed (304 tok/s), Computer Use built in, and US data residency. Kimi K3 wins on overall intelligence (AA Index #4 score 57 vs 3.6 Flash's 50), agentic coding (SWE Marathon 42.0% #1), and frontend development (Design Arena #1). Data residency: 3.6 Flash is US/safe; K3 hosted API has China NI Law risk (open weights July 27 enable safe self-hosting).
