What it excels at

1M token context supports long-document and multi-file tasks. Open weights allow on-premise deployment and customization.

The business tradeoff

Ecosystem and third-party tooling remain narrower than major closed providers. Higher output-token cost relative to input may affect high-volume generation workloads.
