What it excels at

Handles 512k-context batch workloads at low cost ($0.7/$2.2 per M tokens). Suitable for long-document processing and high-volume inference when self-hosted.

The business tradeoff

Open-weights deployment introduces variable latency and throughput depending on hardware and serving stack. Smaller ecosystem and tooling support than major closed providers.
