Shares are measured among model nodes in workflows that entered the corpus in the period, so they reflect current choices rather than the installed base. Anthropic holds 18% of model nodes in Sep 2026 versus 12% in Mar 2026; Google Gemini 15% versus 16%.
OpenRouter at 10% of model nodes means some teams want to swap models without rebuilding workflows. Local models through Ollama account for 4%.
