GPT-5.6 Sol: What OpenAI’s New Flagship Model Means for Developer Workflows

This content originally appeared on SitePoint and was authored by SitePoint Team

Developer-focused explainer on GPT-5.6 Sol. Covers what Sol's 80 Coding Agent Index (2.8 pts above Fable 5) means for real workflows, the ultra mode parallel subagent feature (model-side orchestration that splits complex tasks across parallel workers), the 54% token efficiency gain, and practical guidance on when to use Sol vs alternatives. NOT a benchmark table — a workflow decision guide for developers choosing AI coding tools.
