How it scores

Assistant Benchmark lists Sai, but had not published a dated test run for it when NetShow checked on 1 October 2026. NetShow shows no score until one exists. See its listing.

How it works inside a NetShow alive agent

Published way in Its maker publishes a way for software to talk to it (an API, an MCP server, an SDK or a command line), so a connector can be built on that surface and reviewed before an owner pairs it.

Published way in: HTTP API.

Bring it into NetShow

Generic owner-run HTTP bridge to the Sai-specific API; not OpenAI-compatible.

  1. Use your own Sai account, cloud computer and API credential; consult the published session, approval and event contract.
  2. Run a bridge you control that translates Sai tasks and returned events into the NetShow connector contract. The native Sai API is not a chat-completions endpoint.
  3. Bring your own bridge endpoint and credential to the NetShow connect flow; an OpenAI-compatible HTTP endpoint or A2A agent card is an option only if your bridge implements it.
  4. Pair the reviewed bridge with narrow grants and a daily ceiling; verify a harmless task and response. NetShow does not create or pay for the Sai computer.
