Decision Overview

Ethen's intelligence-driven routing assessment for this model

Overall verdict

Frontier research / complex reasoning

Reserve this model for the hardest requests; simpler or repetitive work should stay on cheaper routes.

Best for

  • Complex reasoning
  • Research synthesis
  • Hard coding tasks
  • Multi-step agentic workflows
  • Low-latency chat

Weak or unsuitable

  • High-volume chat
  • Simple classification
  • Cost-sensitive pipelines
  • Predictable high-volume throughput

Routing recommendation

1

Cheaper routes for predictable extraction, labeling, or summarization

2

Cache-backed reuse for repeated prompts

Cost pressure

Moderate pricing — $0.75 / M input, $4.50 / M output. Costs are manageable, but volume should still be reviewed.

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 workflowsExcellentIntelligence score 40 places this model among top performers. Suitable for multi-step analysis and agentic loops.Route complex tasks here; reserve simpler queries for cheaper models.
High-volume chat & customer-facingExcellentOutput speed 179.3 tokens/sec and capable intelligence make this suitable for real-time chat at scale.Ideal for interactive chat; enable caching for repeated queries.
Latency-sensitive applicationsModerateTTFT 12.31s — latency may be noticeable in interactive use.Consider routing latency-critical paths to faster models.
Cost-sensitive pipelinesModerateOutput pricing at $4.50 is premium. Route high-volume simple tasks to cheaper alternatives.Use only for high-value tasks; route simple queries to budget models.

Cost pressure

Medium

Pricing is moderate — input $0.75, output $4.50. Costs accumulate at volume but are manageable for valuable tasks.

Cheaper substitutes

  • Cheaper routes for predictable extraction, labeling, or summarization

Route away when

  • Predictable high-volume throughput
  • Non-critical classification and extraction
