OpenRouter

Introducing the Fusion API, the smartest compound model in the market. Fusion achieves Fable-level intelligence at half the price. How it works 👇

Plus: docs search now runs on @mintlify, read-only tools no longer trigger permission prompts, and every tool renamed to a clean verb-noun format. Get started in 30 seconds: openrouter.ai/mcp

Two new tools: generate-image (works on Desktop apps that can view images, billed to your key) and send-feedback (report a bad generation straight to the OpenRouter team, no support form).

We just shipped a number of updates to the OpenRouter MCP - 2 weeks of OpenRouter MCP updates in one thread + demo. Your agent can now discover, rank, test, and report on models without leaving your editor 🧵

New: separate leaderboards for open-weight models and closed-weight models on openrouter.ai/rankings

New favorite Codex workflow for non-technical work: "Please use @OpenRouter to ask 3-4 other smart models to challenge your conclusions, and to help decide on the correct answer, update your answer accordingly"

10 weeks since launch. @poolsideai's Laguna M.1 is #11 among open models and #18 across ALL models on @OpenRouter by monthly usage, holding rank in one of the fastest-moving leaderboards in AI. 🔥 Just getting started.

Learn how to use service tiers: openrouter.ai/docs/guides/fe…

Service tiers are now first-class on OpenRouter. See tier-specific latency and throughput in `/v1/models/endpoints` so you know exactly what you’re paying for. Route with copyable slugs like `openai/flex` and `xai/priority`, or keep using the existing `service_tier` param.

hot take: choosing the best coding model is easy but for everything else - translations, summarization, data extraction, etc - it's all based on vibes we just shipped task type insights on @OpenRouter mcp - see what models ppl are using for specific tasks, backed by prod usage

Read our story about the rebrand: openrouter.ai/blog/announcem…

OpenRouter has a new look. As we’ve grown into the infrastructure powering the intelligence era, our brand needed to evolve too. Built on clarity, precision, and purpose. For developers. For enterprises. For everyone turning intelligence into impact.

GPT-5.6 Luna: the fast, low-cost tier. Tuned for high-volume, latency-sensitive work like chat, classification, and lightweight agents, with real GPT-5.6 reasoning. openrouter.ai/openai/gpt-5.6…

GPT-5.6 Terra: the balanced everyday driver. Coding, reasoning, and agentic tasks at GPT-5.5-competitive quality for roughly 2x lower cost. openrouter.ai/openai/gpt-5.6…

GPT-5.6 is live on OpenRouter! Sol (flagship), Terra (balanced), and Luna (fast + low-cost). In our early testing, the 5.6 models were more token efficient, leading to lower cost and faster time to task completion. AA's results agree. More on Sol, Terra, and Luna below 🧵
