What it excels at
Supports 1M-token context and 64k output, enabling extended document and multi-turn analysis workloads. Open weights allow self-hosted deployment at listed per-token rates.
The business tradeoff
Preview status implies limited production validation and potential gaps in instruction following or edge-case stability. Output-token pricing and hosting variance remain operator-dependent.
