A knowledge-based AI application platform with visual workflows, editable document chunks and shareable chat or API outputs, available through a free self-hosted community edition.
FastGPT helps turn reference material and model calls into an application people can use repeatedly. Its community route combines knowledge-base processing, retrieval and visual workflow orchestration, with sharing links or APIs for delivery. It is particularly relevant when someone needs to maintain the material behind an answer rather than merely send a one-off prompt.
The product name does not mean it is a free hosted version of a particular GPT model. You still select and configure the model services. Start with a small internal question-answering app and a known collection of documents. As the application becomes useful, inspect missing knowledge, retrieval behavior and workflow branches before making it more autonomous.

Example prompt or task: Answer only from the approved FAQ. Give the applicable rule and its exceptions, then identify the supporting source. If the user has not specified the product edition, ask for it before describing edition-specific behavior.
This suggested workflow is an editorial example. It does not claim that a community deployment includes every advanced evaluation or administration feature shown in commercial documentation.
Some administration, permission and evaluation features belong to commercial offerings. Check the edition comparison.
The self-hosted community edition provides the free software path. Compute, storage, model calls, embeddings and third-party tools can still incur costs. Managed deployment and commercial support are different purchases from downloading the community project.
The official edition comparison lists workflows, knowledge bases, sharing links and APIs in the community route. Features such as SSO, team spaces and permissions, file-level knowledge permissions and certain evaluation or operational dashboards are not universally community features. Check the current matrix for the specific capability you need.
It provides a free self-hosted software route under the project license. Hosting, inference and external services are separate.
No. FastGPT is an application platform. Model availability and cost depend on the providers or local model servers you configure.
Knowledge chunks can be maintained and corrected. Keep changes consistent with the original approved source and test affected questions afterward.
No. The FastGPT license adds conditions concerning similar multi-tenant SaaS services and console branding. Read the full license before commercial redistribution.
The current edition comparison places these enterprise capabilities in commercial offerings. Verify the exact feature and edition before designing around it.
Check document processing, knowledge records, retrieval and prompt context separately. Switching to a larger model is not the only possible remedy.
The project supports sharing, embedding and API-oriented delivery. Use a collection appropriate for that audience and validate access before distributing the entry point.
Explore platforms, inputs and outputs, licensing, and access requirements.
FastGPT is used through a browser after deployment. The Docker guide covers multiple components, so plan for database and application persistence rather than backing up only the visible configuration. Use release-matched instructions when upgrading a working installation.
Input files become knowledge records used by retrieval and generation. The resulting application can deliver conversational answers or structured output according to its flow. Automated ingestion is not an assurance that every spreadsheet layout, scan or slide is understood correctly; inspect a representative example before importing a whole archive.
A self-hosted database can keep stored knowledge under your control, while a cloud model or embedding service still receives the material required for its requests. Review the selected services and the scope of shared apps rather than relying on the word private deployment alone.
FastGPT’s license is based on Apache-2.0 with additional conditions. Similar multi-tenant SaaS operation and removal or modification of console branding can require commercial authorization. This page describes available product paths without replacing the current license or edition matrix.
