OpenRouter Monthly Traffic Trends
OpenRouter experienced a 12.6% decline in traffic, with a drop of 1.3M visits. The rise of Grok Code, which now captures 46.4% of coding traffic, might have diverted users from other models on the platform. Additionally, the introduction of GPT-5 and enhanced multimodal capabilities in August 2025 did not significantly impact traffic, suggesting that user retention may be affected by factors beyond new features.
