Architectural Strengths vs. Operational Considerations
An objective technical balance sheet analyzing deployment advantages and production constraints.
Key Architectural Strengths
- Industry gold standard for automated GitHub issue solving, feature authoring, and test generation.
- Superb price-to-performance ratio ($3 / $15) with prompt cache reads down to $0.30 per million tokens.
- High-throughput token emission (80 tps peak) for interactive developer tooling and live completions.
Operational Considerations
- Deep multi-step mathematical theorem derivation is best delegated to Opus 4.
