    "description": "The definitive OpenRouter integration for Open WebUI. Full catalog (chat / TTS / audio / image / video / embeddings), with native rendering for every output modality: image-gen models (flux, gemini-image-preview, ...) materialize generated data URLs to internal OWUI files and embed as ![](/api/v1/files/.../content); video-gen models (veo, kling, sora, seedance, hailuo, wan, grok-imagine) route through the async /api/v1/videos endpoint with polling, then re-host the MP4 and embed via OWUI's block-HTML <video> token; audio-gen models (lyria, gpt-audio with auto pcm16 → WAV wrap) stream base64 chunks via /chat/completions modalities=['text','audio'] and embed as block-HTML <audio>. SSRF-guarded media downloads (openrouter.ai-only whitelist + 100MiB/50MiB byte caps + MIME post-download whitelist). Variant routing (:nitro/:exacto/:thinking/:online/:free/:extended), web search plugin with domain filters, server-side category filter, deprecation warnings, extended reasoning (minimal→xhigh + max_tokens + summary), Anthropic interleaved thinking + cache TTL, ZDR enforcement, tool/free-tier filters, provider preferences (only/quantizations/max_price/allow_fallbacks), service tier routing (flex/priority), generation-ID auditability, cached-input cost breakdown, model fallbacks, middle-out compression, citations (URL-scheme filtered), auto-discovered provider icons. Per-user API keys and preferences via UserValves, with at-rest key encryption (Fernet, keyed on WEBUI_SECRET_KEY) and cached decrypt. Native function/tool calling (parallel execution, streaming + non-streaming) with a tool-iteration cap, and an opt-in OpenRouter remaining-credit footer (pre-warmed off the event loop so the SSE stream is never blocked). Transient 429/5xx retries with Retry-After awareness, HTTPAdapter pool sized for concurrent users, atomic routing-set swap so concurrent refreshes never expose an empty model list.",
