New Features: Reasoning Streams, Crypto Invoices, End-User IDs & More

We're actively expanding Claude 4 and Gemini 2.5 capacity — but in the meantime, several highly requested features are now available:

🧠 o3 Reasoning Summary Streaming

OpenAI’s o3 and o4-mini models now support streaming reasoning summaries via the OpenRouter Chat Completions API.

🧑‍🤝‍🧑 Submit End-User IDs

You can now include optional user fields with each request to help prevent abuse, improve moderation, and enable per-user usage tracking.

📜 Crypto Invoices

You can now generate an invoice in one click to pay with crypto directly from the /credits page.

🔑 Require Your 3rd-Party Key

Ensure only your API key is used for a specific provider (e.g., your own OpenAI key) by toggling this setting from the model config.
