Providers

Scaleway Paris, Tensorix Frankfurt, AWS Bedrock `eu-central-1` — what each one hosts.

CleverRouter routes to three EU-resident inference providers. Every model runs in a European data centre. No US fallback, no us-east-1, no non-EU shadow routing.

At a glance

Provider	Region	Strengths	Activation
Scaleway	Paris (`fr-par`)	Chat, embed, audio, Pixtral vision	Always on
Tensorix	Frankfurt	Chat, embed, fast Whisper	If `TENSORIX_API_KEY` set
AWS Bedrock	`eu-central-1`	Cohere embed + rerank, Amazon Nova	If `AWS_BEDROCK_API_KEY` set

Scaleway (Paris, FR)

OpenAI-compatible passthrough to https://api.scaleway.ai/<project-id>/v1.

Endpoint	Notes
Chat	Streaming, tool calls, vision (Pixtral), JSON mode
Embeddings	`baai/bge-multilingual-gemma2`, `qwen/qwen3-embedding`
Audio	`openai/whisper-large-v3`
Rerank	Not supported

Tensorix (Frankfurt, DE)

OpenAI-compatible passthrough to https://api.tensorix.ai/v1. The fast-whisper variant beats vanilla Whisper on throughput.

Endpoint	Notes
Chat	Streaming, tool calls
Embeddings	`qwen/qwen3-embedding-8b`
Audio	`systran/faster-whisper-large-v3`
Rerank	Not supported

AWS Bedrock (`eu-central-1`)

Special case: Bearer API key (ABSK format, not SigV4) plus a custom Converse-schema mapping. Active when the gateway has AWS_BEDROCK_API_KEY set.

Endpoint	Notes
Chat	Streaming, tool calls, vision (Anthropic, Nova)
Embeddings	`cohere/embed-v4`
Audio	Not supported
Rerank	`cohere/rerank-v3-5`, `amazon/rerank-v1`

Bedrock model IDs

Bedrock model IDs always use the eu. or global. regional prefix — never us.*. CleverRouter refuses to route to non-EU Bedrock models at request validation.

EU-only invariant

EU-only routing is an architectural constraint, not a setting:

No US providers. No US fallback. No multi-region failover that crosses the EU border.
Bedrock model IDs validated against the eu.* / global.* prefix.
All gateway containers run in Scaleway Paris (fr-par).

See Trust → Zero data retention and GDPR & DPA for the full data-flow story including sub-processors.

How a provider is chosen per request

For models hosted by more than one provider, the gateway picks in order:

Explicit pin (X-CleverRouter-Provider) — see Provider pinning.
Priority sort (model_providers.priority ASC, lowest wins).
Health filter — providers marked down in the last health probe are skipped (unless all are down).
Disabled or deprecated mappings are ignored.

What's coming

More EU regions on Bedrock — pending AWS rollout of additional Anthropic models in eu-central-1.
Possible OVH / Bento.AI integration when they cover models we don't already have through Scaleway or Tensorix.
