The outcome

Answer authorized users from current source material without unsupported claims or cross-team leakage.

FastGPT is a Open-source AI application platform for knowledge bases, conversational agents, visual workflows, plugins, Agent V2, and OpenAI-compatible APIs. Building grounded Q&A applications from documents, composing visual AI workflows and plugins, and publishing controlled agents through web channels or APIs. This guide narrows that broad capability into one repeatable outcome, with checkpoints that keep the source material and your judgment in the loop.

Before you begin

Set the boundary before the tool starts.

Choose one real task, identify who will use the result, and decide what evidence or test will make the result acceptable. Gather only the source material needed for that task. If the work contains confidential, personal, regulated, or client-owned information, confirm that the platform and account are approved before sharing it.

Troiana principle

AI should make the work easier to inspect. If the workflow removes the source, the owner, or the review step, redesign the workflow.

Step by step

A workflow you can repeat.

  1. 01

    Define users, team, questions, source owners, data classes, document permissions, freshness, answer and citation rules, model and embedding choices, retention, and evaluation thresholds.

  2. 02

    Create an isolated knowledge base, ingest minimal approved documents, inspect parsed text and images, and record source, owner, rights, version, audience, and expiry metadata.

  3. 03

    Tune chunking and retrieval on labeled questions, add reranking only when measured, require cited evidence and abstention, and keep history and context within explicit limits.

  4. 04

    Test correct, ambiguous, no-answer, stale, conflicting, multilingual, permission-boundary, prompt-injection, poisoned-document, malformed-file, deletion, and provider-failure cases.

  5. 05

    Publish to a limited audience, monitor retrieval and feedback, reindex reviewed changes, audit team access, and support source correction, expiry, export, deletion, and incident response.

Working standard

What good use looks like.

  • Inspect parsed documents before indexing.
  • Require citations or abstention.
  • Test retrieval prompt injection.

FastGPT API keys act with the current member's access inside a team, so they may reach more than one app. OpenAI compatibility does not narrow that scope. Self-hosting requires secure cookies, origins, proxies, SSRF controls, databases, object and vector storage, code sandboxing, secrets, and patches. Isolate teams, minimize keys, validate uploads, constrain HTTP and tool nodes, require human approval, and test backup, restore, deletion, and billing.
