Executive Assessment

Routing Verdict & Tradeoffs

Ethen Routing Verdict

Capable everyday model

o1-pro scores 19 (estimated) on the Artificial Analysis Intelligence Index, placing it below average among other reasoning models in a similar price tier (median: 28). o1-pro costs $150.00 per 1M input tokens (at the higher end, median: $1.50) and $600.00 per 1M output tokens (at the higher end, median: $8.40), based on the median across providers serving the model.

Good for routine tasks; route complex reasoning and premium workloads to stronger models.

Task Fit Assessment

WorkloadRatingNotes
Complex reasoning & agentic workflowsviableIntelligence score 19 handles routine reasoning but may struggle with open-ended agentic tasks.
Cost-sensitive pipelinesviableOutput pricing at $600.00 is premium. Route high-volume simple tasks to cheaper alternatives.

Cost Pressure Analysis

High

Pricing is premium — input $150.00, output $600.00. This model is expensive for high-volume or output-heavy workloads.

Cheaper substitutes: Lower-cost models for repetitive or high-volume work, Cache-backed reuse for repeated prompts
