Strengths
Delivers significant capability gains over 3.7 Flash in software engineering, agentic tasks, and multi-step reasoning while maintaining the speed profile of the Flash tier.
Best for
Batch processing workflows that require reasoning depth beyond 3.7 Flash, such as complex code generation, multi-turn agent loops, and video or audio analysis at scale.
Limitations
A newer release than 3.7 Flash (batch) with limited production history; not suitable for workloads requiring the absolute fastest latency or most resource-constrained environments.
