Async inference API for long-horizon AI agents, serving leading open-source models through OpenAI- and Anthropic-compatible endpoints.
Sail's inference API runs leading open-source models behind OpenAI- and Anthropic-compatible Responses, Chat Completions, and Messages endpoints, so existing agent code can migrate with minimal change. A per-request completion window lets callers trade response latency for token price, with background tiers priced well below immediate-response options.
Self-serve users start with monthly free credits and prepaid usage-based billing, while enterprise customers contract for volume pricing, HIPAA-region isolation, and uptime SLAs. The platform targets asynchronous, long-running agent workloads such as deep research, code review, and evaluation pipelines.
