Product / UX / UI & API

OpenRouter

Commercial API gateway that exposes 400+ models from 60+ providers (OpenAI, Anthropic, Google, Meta, DeepSeek, plus open-weights hosts) behind a single OpenAI-compatible endpoint with automatic failover and unified billing. The dominant closed-source LLM aggregator: ~$50M annualized revenue and reportedly raising $120M at a $1.3B valuation (CapitalG-led) in early 2026.

OpenRouter unified LLM API gateway/router, live June 2026 (openrouter.ai homepage). Routes/aggregates API calls across 400+ models and 60+ providers behind one OpenAI-compatible API; not a chat UI but a routing gateway, squarely the ui_api gateway slot alongside the LiteLLM anchor. Proprietary hosted service.

Adoption

4 high confidence

4.0

Vendor homepage (primary) reports 100T monthly tokens processed and 8M+ global users; ~250k+ apps. Token volume corroborated by external coverage (~25T tokens/week, ~1.5 quadrillion/yr run-rate; Menlo, TechCrunch on $1.3B valuation / $113M raise May 2026). Reach placed at 1M-10M on the 8M user figure; usage-volume signal is genuinely massive.

Capability

5 high confidence

5.0

Frontier-defining for the gateway slot, broadest provider coverage + routing/fallback at the largest measured token scale; the closed counterpart that sets the bar LiteLLM (C4) approaches on the open side.
