    GIF Prompts, Omni Search, Tool Caching, and BYOK Flags

    6/4/2025

    Several highly requested developer features just landed — making OpenRouter smoother, smarter, and faster to build with:

    🖼️ GIF Support Across Models

    You can now send image/gif prompts to OpenAI, Gemini, Anthropic, and Llama models.
    No need to pre-convert — just send your animations directly.

    🔍 Provider Pages in Omni-Search

    Press ⌘/Ctrl + K, type any provider name, and jump straight to their page to view available models, pricing, and uptime.

    ⚡ Anthropic Tool-Call Caching

    Tool calls with Anthropic now support caching — significantly reducing both latency and token usage.

    🔑 is_byok Flag in Usage

    When you include "usage": { "include": true } in your request, the response now includes an is_byok flag.
    This helps confirm whether a BYOK (bring your own key) setup was used.
