Verdict: This model is genuinely best at cost efficiency (Cost efficiency 96.5/100) and weakest at multimodal work (images, audio, video), complex, multi-step reasoning, agentic tool use (Multimodal 15.5, Reasoning 62.4, Tool use 65.7/100).

Auto-derived from average scores (strengths ≥ 90, weaknesses < 75; cost included).
