ran Opus 5.5 and GPT-6 Sol side by side, here's what actually separates them
Opus 5.5:
- Anthropic's frontier model, beats Fable 5.1 across nearly every benchmark, agentic coding 66.4% vs 55.8% - 40% cheaper than Opus 5, $4/$20 per million tokens - noticeably less verbose, leads with the actual answer instead of burying it - takes longer on complex tasks, 35 min and ~200K output tokens on a Blender scene, but the extra thinking shows in the output, full walkable game environments, near-exact SVG logo recreation
GPT-6 Sol:
- sits below GPT-6 Astra, a cheaper, faster tier, not OpenAI's top m
