Architectural Strengths vs. Operational Considerations
An objective technical balance sheet analyzing deployment advantages and production constraints.
Key Architectural Strengths
- Sub-100ms time to first token (95ms TTFT) with 180 tps peak throughput.
- Unbeatable edge economics: $0.50 / $2.50 per 1M tokens with $0.05 cache reads.
- Delivers Claude 4 Sonnet level reasoning capabilities in a lightweight format.
Operational Considerations
- Best suited for high-volume automated routines rather than novel mathematical theorems.
