NeuralWatt
Hosted, OpenAI-compatible inference with energy-based pricing: pay a flat $5.00/kWh for actual GPU energy consumed (up to 95% cheaper on efficient models) instead of per-token, with real per-request energy metrics on every response. Standard per-token pricing and kWh-based monthly subscriptions ($20/$50/$100) are also available. Powered by Neuralwatt Optimize, also available for self-hosted vLLM via Neuralwatt Deploy.
