Routing Verdict & Tradeoffs
Budget-friendly / task-specific model
Phi-4 scores 5 (estimated) on the Artificial Analysis Intelligence Index, placing it below average among other open weight non-reasoning models of similar size (median: 6). Phi-4 generates output at 33.6 tokens per second (based on Microsoft's API), which is at the lower end compared to other open weight non-reasoning models of similar size (median: 101.8 t/s). Phi-4 costs $0.13 per 1M input tokens (better than average, median: $0.15) and $0.50 per 1M output tokens (somewhat higher than average, median: $0.32), based on Microsoft's API.
Best for high-volume, simple, or domain-specific tasks where cost or speed matters more than deep reasoning.
Task Fit Assessment
| Workload | Rating | Notes |
|---|---|---|
| Complex reasoning & agentic workflows | suboptimal | Intelligence score 5 is better suited for straightforward tasks than multi-step reasoning. |
| High-volume chat & customer-facing | viable | Output speed may be a bottleneck for real-time chat at scale. |
| Latency-sensitive applications | optimal | TTFT 2.11s — adequate latency for most interactive use cases. |
| Cost-sensitive pipelines | optimal | Output pricing at $0.50 is reasonable for moderate volume. |
Cost Pressure Analysis
Low
Pricing is competitive — input $0.13, output $0.50. Suitable for sustained production use.

AA-Omniscience Index
AA-Omniscience Index (higher is better) measures knowledge reliability and hallucination. It rewards correct answers, penalizes hallucinations, and has no penalty for refusing to answer. Scores range from -100 to 100, where 0 means as many correct as incorrect answers, and negative scores mean more incorrect than correct. · Evaluation results measured independently by Artificial Analysis
