Hello, my question is in the title: what are the main differences between a project and a custom GPT

Hi @limber trench. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Certainly! Here are the main differences between a Project and a Custom GPT in ChatGPT:

Projects

  • Purpose: Projects are designed to help you organize and manage multiple chats, files, and context under a shared objective or workflow (e.g., "Wedding Planning" or "App Redesign").
  • Features: Within a project, you can:
    • Group related chats and files together.
    • Set project-specific instructions that override your global ChatGPT custom instructions.
    • Upload files (PDFs, spreadsheets, images) for context.
    • Use built-in tools like Canvas, Advanced Data Analysis, DALL·E, and Search.
    • Share individual chats from a project (but not the whole project or its files/instructions).
  • Collaboration: Primarily for personal organization, but you can share individual chats via links.
  • Model: Chats in projects use GPT-4o and support the latest features available to your plan.
  • Access: Available to Plus, Pro, and Team users, with Enterprise and Edu support rolling out soon.
  • No Coding Required: Projects are managed entirely through the ChatGPT interface—no coding needed.

Custom GPTs

#
  • Purpose: Custom GPTs are specialized versions of ChatGPT that you can tailor for specific tasks, topics, or workflows (e.g., a coding assistant, a language tutor, or a support bot).
  • Features: When creating a custom GPT, you can:
    • Set detailed instructions and behavior.
    • Upload files as knowledge sources for the GPT to reference.
    • Enable or disable specific capabilities (web browsing, image generation, code interpreter, custom actions via APIs).
    • Share your GPT with others, publish it to the GPT Store, or keep it private.
  • Collaboration: Custom GPTs can be shared with individuals, your workspace, or the public via the GPT Store.
  • Model: You can select from a range of models (e.g., GPT-4o, o3, o4-mini) for your GPT, depending on your needs and plan. GPTs with custom actions are currently limited to GPT-4o and 4.1.
  • No Coding Required (Basic): You can create and configure GPTs without coding, but advanced features (like custom actions) may require some technical setup.
  • Access: Available to Plus, Pro, Team, Enterprise, and Edu users for creation; Free users can use GPTs from the store with some limitations.

Summary Table

#
Feature Projects Custom GPTs
Main Use Organize chats/files for a goal/workflow Create specialized assistants for tasks/topics
Instructions Project-specific, override global settings GPT-specific, define behavior and knowledge
File Uploads For context in all project chats For knowledge base of the GPT
Tools Built-in (Canvas, DALL·E, Data Analysis, etc.) Selectable per GPT (Browsing, APIs, etc.)
Sharing Share individual chats Share/publish the entire GPT
Model Selection Uses GPT-4o Choose from available models
Coding Required No No (unless using advanced custom actions)
Access Plus, Pro, Team (Enterprise/Edu soon) Plus, Pro, Team, Enterprise, Edu (creation)

In short:

  • Projects are for organizing and contextualizing your work within ChatGPT.
  • Custom GPTs are for building and sharing specialized AI assistants with custom behaviors and knowledge.
