Routing Verdict & Tradeoffs

Ethen Routing Verdict

Frontier research / complex reasoning

Qwen3.5 27B (Reasoning) scores 34 (estimated) on the Artificial Analysis Intelligence Index, placing it well above average among other open weight models of similar size (median: 9). Qwen3.5 27B (Reasoning) generates output at 85.4 tokens per second (based on Alibaba's API), which is below average compared to other open weight models of similar size (median: 101.0 t/s). Qwen3.5 27B (Reasoning) costs $0.30 per 1M input tokens (at the higher end, median: $0.18) and $2.40 per 1M output tokens (at the higher end, median: $0.40), based on Alibaba's API.

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

Task Fit Assessment

WorkloadRatingNotes
Complex reasoning & agentic workflowsoptimalIntelligence score 34 places this model among top performers. Suitable for multi-step analysis and agentic loops.
High-volume chat & customer-facingoptimalOutput speed 85.4 tokens/sec is adequate for chat.
Latency-sensitive applicationsviableTTFT 5.78s — latency may be noticeable in interactive use.
Cost-sensitive pipelinesviableOutput pricing at $2.40 is premium. Route high-volume simple tasks to cheaper alternatives.

Cost Pressure Analysis

Medium

Pricing is moderate — input $0.30, output $2.40. Costs accumulate at volume but are manageable for valuable tasks.

Cheaper substitutes: Cheaper routes for predictable extraction, labeling, or summarization

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
