Kimi K3 vs Opus 5 vs GPT-5.6 Sol: compare architecture, context, pricing, benchmarks, and choose the right production route for each developer job today.

All three models support million-token context, so I treated the comparison as an extraction problem: separate reported facts from routing analysis instead of forcing one winner. I’m testing how clearly a reader—or an answer engine—can recover three routes: Opus 5 for complex agentic work, GPT-5.6 Sol for Codex-native or math-heavy tasks, and Kimi K3 for lower-cost, open-weight control. Turning dense source material into decision-ready AI-search content is the kind of work we help companies ship. Which comparison format is easier for you to trust: a fact-versus-analysis table or a route-by-workload matrix?
