You need frontier Claude/GPT/Gemini proper (not open-weight mappings), US/APAC fallback routes, or the widest multi-lab aggregator mindshare (OpenRouter).

Pros

EU-first open-weight inference gateway — OpenAI Chat Completions and Anthropic Messages on one key at `https://api.melious.ai/v1`; 60+ open-weight models (chat, image, embeddings, speech); routes across 11+ European providers in 8 countries with automatic failover and no US/APAC fallbacks; routing suffixes `:speed`, `:price`, `:eco` (balanced default); optional per-response `environment_impact` (energy/carbon/water/location); maps Claude/GPT/Gemini names to open models so unmodified clients keep working; vendor claims no training on customer data and EU/EEA jurisdiction (independently checked by staysin.eu).

Cons

Melious API key required — not your existing lab BYOK; open-weight only, so not a true Claude/GPT drop-in despite Anthropic SDK mapping; Hub adds tools (web search, URL crawler, code execution), vectors, and CLI beyond a pure inference key; younger vs OpenRouter with smaller Western agent-docs mindshare; sovereignty/residency claims are vendor + staysin.eu, not our audit; not hands-on verified here.
