What is Doubleword?
Doubleword is an AI inference platform that provides high-volume async and batch processing for open-weight models. It offers a cost-effective alternative to real-time APIs, with pricing based on delivery windows (realtime, async, or 24-hour batch). The platform is designed for long-horizon agents, batch pipelines, and high-volume tasks, claiming up to 90% cost savings.
How to use Doubleword?
- To use Doubleword, you can switch from existing OpenAI or Anthropic SDKs by updating your base URL to api.doubleword.ai. The API is OpenAI-compatible, so no code rewrites are required. You can then choose your delivery window (realtime, async, or batch) and start sending requests. For large-scale workloads, Doubleword offers webhook triggers and supports strict JSON schemas for structured outputs.
