The outcome

Get into the official FastGPT experience with the right account and a setup you understand.

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

    Start at https://fastgpt.io/ and confirm the domain before entering account or payment information.

  2. 02

    For desktop use, follow the official download link. Current availability: FastGPT is used through a hosted or self-hosted web application and API rather than a standalone desktop client..

  3. 03

    A FastGPT cloud account or secured self-hosted stack, configured chat, embedding and optional reranking models, team and key permissions, approved documents, object and vector storage, backups, monitoring, and cost and workflow limits.

  4. 04

    Sign in with the account you intend to keep using, then review plan, data, notification, and permission settings.

  5. 05

    Run one low-risk test task before connecting sensitive files, repositories, or workspace data.

Working standard

What good use looks like.

  • Use official download pages.
  • Review permissions during setup.
  • Keep installers and applications updated.

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.
