Decision Overview

Ethen's intelligence-driven routing assessment for this model

Overall verdict

Budget-friendly / task-specific model

Best for high-volume, simple, or domain-specific tasks where cost or speed matters more than deep reasoning.

Best for

  • Simple Q&A
  • High-throughput chat
  • Classification
  • Extraction
  • Low-latency chat
  • Interactive turn-taking

Weak or unsuitable

  • Complex reasoning
  • Creative writing
  • Multi-step tasks

Routing recommendation

1

Use the fit matrix to compare against cheaper routes when volume rises

Cost pressure

Competitive pricing — $0.05 / M input, $0.40 / M output. Cost pressure is low enough for sustained production use.

Model-fit matrix

Use this model where capability pays for itself; route away where volume, latency, or budget dominate.

Use caseFitReasonRouting note
Complex reasoning & agentic workflowsWeakIntelligence score 8 is better suited for straightforward tasks than multi-step reasoning.Avoid routing complex agentic tasks to this model.
High-volume chat & customer-facingStrongOutput speed 146.5 tokens/sec is adequate for chat.Suitable for chat; monitor latency under concurrent load.
Latency-sensitive applicationsExcellentTTFT 0.94s — among the lowest latencies, suitable for interactive latency-critical use cases.Good first choice for real-time applications.
Cost-sensitive pipelinesExcellentOutput pricing at $0.40 is very competitive for high-volume workloads.Excellent for budget-constrained pipelines; enable caching to reduce costs further.

Cost pressure

Low

Pricing is competitive — input $0.05, output $0.40. Suitable for sustained production use.

Cheaper substitutes
