Executive Assessment

Routing Verdict & Tradeoffs

Ethen Routing Verdict

Budget-friendly / task-specific model

Jamba 1.5 Mini scores 3 (estimated) on the Artificial Analysis Intelligence Index, placing it at the lower end among other open weight non-reasoning models of similar size (median: 7). Jamba 1.5 Mini costs $0.20 per 1M input tokens (very competitive, median: $0.53) and $0.40 per 1M output tokens (very competitive, median: $1.05), based on the median across providers serving the model.

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

Task Fit Assessment

WorkloadRatingNotes
Complex reasoning & agentic workflowssuboptimalIntelligence score 3 is better suited for straightforward tasks than multi-step reasoning.
