Auditable agent infrastructure with SERV Reasoning
Works with the OpenAI and Anthropic SDKs by changing only the base URL and API key, so existing prompts and code carry over without migration.
Routes every model call through typed, validated reasoning steps, which OpenServ reports as lower cost per 100 calls, fewer failures, and faster inference.
A dashboard tracks every decision, cost, and step an agent takes, making AI-driven outcomes traceable and easier to defend to stakeholders.
Teams can assemble and deploy agents without writing orchestration code, then graduate to the API when they need more control.
