JouleCloud places every request on the lowest-cost node that is passing live health checks — power-cost-aware routing across a fleet of GPUs, behind one OpenAI-compatible endpoint. Change one base_url; keep your existing SDK, code, and models.

Change one line. Same request and response shapes, same SDKs.
The full live catalog is visible in your console after sign-in. See all models.
Every request lands on the cheapest node that is currently healthy — cost and health scored together, per request.
Same request and response shapes as the OpenAI API. Change one base URL and keep your SDK, code, and prompts.
If the chosen node fails a health check, the same request retries on the next-cheapest healthy node. The caller sees one response.
Select any served model with the model field. One endpoint, one key, several open-weight models.
Create an account and an organization. Your key, budget, and usage are scoped to the org.
One gateway key is minted on demand in the console. Reveal, copy, or rotate it any time.
Point your existing OpenAI client at https://api.jouledns.com/v1 and start calling models.
Each incoming request is placed on the cheapest node that is currently healthy — cost and health are scored together, per request.
“Healthy” means the node is passing live health checks: it is reachable, serving the model, and responding within bounds.
If the chosen node fails, the same request retries on the next-cheapest healthy node. The caller sees one response — the failover is transparent.
JouleCloud serves open-weight models on its own GPU fleet — currently Qwen2.5 Instruct (7B and 3B). See the models page.
Usage-based, per token — $0.20 per 1M input tokens and $0.60 per 1M output tokens, one rate across all models. No tiers or minimums. See pricing.
Yes — same request and response shapes. Point the official OpenAI SDKs at our base URL and pass your org key. See the docs.
JouleCloud is in private preview. The served catalog is intentionally small, streaming is in preview, and each org has a single shared key today. We only advertise what we actually run.
