Custom GPT Alternatives (2026): 6 Places to Move Your GPTs

OpenAI is retiring Custom GPTs on December 11, 2026. FedRAMP workspaces and Enterprise workspaces with an approved deferral get until February 11, 2027. OpenAI’s built-in path turns each GPT into a ChatGPT plugin, but custom actions, the GPT’s selected model and its sharing audience don’t carry over on their own. If you rely on GPTs, you are rebuilding part of each one either way. The best Custom GPT alternative is TypingMind. Each GPT becomes an AI agent with the same instructions, files and API calls, and it runs on any model. AI agents come with personal TypingMind and with TypingMind Teams, so this works for one person or a whole company.

​

What happens to Custom GPTs

From OpenAI’s Custom GPT retirement FAQ, updated in November 2026:

• Retirement date: December 11, 2026 for most accounts. On that date, Custom GPTs and their GPT pages become inaccessible.
• Migration to plugins: the GPT’s instructions become a skill, its knowledge files become reference files, and connected apps are added as apps. Migration uses the latest published version; drafts don’t transfer.
• What doesn’t carry over: custom actions, the selected model, and the sharing audience. A migrated plugin starts private.
• After migration: the original GPT becomes read-only and its creator can’t delete it.
• Past chats: existing conversations with Custom GPTs stay accessible after retirement, but can’t be moved into a project.
• Enterprise: new GPT creation ended on October 26, 2026 in affected Enterprise workspaces.

​

How we compared these options

We checked each option on five things:

1. Custom actions: can a rebuilt GPT still call your APIs?
2. Models: can each assistant run on the model that suits it best?
3. Sharing and control: can you share assistants with the right people, and limit access and cost?
4. Where it runs: the vendor’s cloud, or your own servers.
5. Price: what it costs to get started.

​

Custom GPT alternatives at a glance

TypingMind and LibreChat need API usage from your AI providers on top of the price above.

​

1. TypingMind: agents that keep every part of your GPT

Best for: anyone whose GPTs call APIs or need a specific model, from one person to a whole company. AI agents are TypingMind’s version of Custom GPTs: reusable assistants with their own instructions, knowledge and tools. They come with personal TypingMind and with TypingMind Teams. Every part of a GPT has a place:

​

Your custom actions keep working

Each custom action becomes a plugin that calls the same API, with API key or OAuth authentication. You can also connect MCP servers, install Agent Skills and run code in the Code Sandbox.

​

Any model for each agent

Run one agent on Claude and another on GPT or Gemini, each with its own parameters. Switch an agent to a newer model in a few clicks when one comes out.

​

For teams: control who uses each agent, and what it costs

On TypingMind Teams, share agents with your workspace or limit them to user groups. On the Professional plan, set usage limits per model, agent, plugin or user, and turn on SSO, roles, chat logs and audit logs.

​

Bring your chat history

Each person can import their ChatGPT export under App Settings → All Data → Import From OpenAI, so old conversations sit next to the new agents. If your company’s data must stay in-house, TypingMind Teams can run on your own servers.

​

2. ChatGPT plugins and projects: OpenAI’s own path

Best for: GPTs that are only instructions and files, for teams staying on ChatGPT. When migration is available for your account, open My GPTs and select Migrate to plugin. Instructions become a skill, knowledge files become reference files, and connected apps come along. For GPTs you used for ongoing work, OpenAI also suggests a ChatGPT project, which keeps chats, files and instructions together. Good to know:

• Custom actions don’t transfer. Rebuilding them may need a custom MCP server and technical setup.
• The GPT’s selected model doesn’t carry over.
• A migrated plugin starts private, and the original GPT becomes read-only.

Pricing: included in your ChatGPT plan. ChatGPT Business is $25 per user per month ($20 billed annually).

​

3. Claude Projects: if your team is moving to Claude

Best for: teams that want to switch from OpenAI to Anthropic. Claude Team gives you Projects, which keep instructions, files and chats together, plus connectors for remote and local tools, SSO and admin controls for connectors. Good to know:

• Anthropic models only.
• Role-based access, SCIM and audit logs are on the Enterprise plan, with a 20-seat minimum.

Pricing: $25 per user per month ($20 billed annually). See Claude Team alternatives.

​

4. Gemini Gems: if your team is on Google Workspace

Best for: companies already on Google Workspace. Gems are custom versions of Gemini with their own instructions and files. Workspace users can share Gems with people in their organization, and admins can turn Gem sharing on or off. Good to know:

• Google models only.
• Google’s pricing page doesn’t list a way to call your own APIs from a Gem.

Pricing: Business Standard is $14 per user per month with a 1-year commitment. Business Plus is $22.

​

5. Copilot agents: if your team is on Microsoft 365

Best for: companies already on Microsoft 365. Microsoft 365 Copilot lets you build agents with Agent Builder and Copilot Studio, connect external data through Copilot connectors, and use them inside Word, Excel, Outlook and Teams. Good to know:

• The Copilot Business add-on needs an eligible Microsoft 365 Business plan.
• Some advanced AI features are billed by usage on top of the license.

Pricing: Copilot Business add-on $21 per user per month, paid yearly ($18 on a first-year promotion until December 31, 2026).

​

6. LibreChat agents: if you want to self-host for free

Best for: engineering teams that want to run the code themselves. LibreChat is a free, open-source platform under the MIT license. It lets you build agents with your files, tools and reusable skills, and supports many providers and local models. Good to know: you install, update, secure and back up the server yourself. Pricing: free; you pay for your server and API usage. TypingMind gives you agents without that work, and TypingMind Teams can still be self-hosted.

​

Before December 11: a checklist

1. List your GPTs. Note which ones your team uses, who owns each one, and who needs access.
2. Save each GPT’s parts. Copy the instructions and conversation starters, download the knowledge files, and export the OpenAPI schema of every custom action.
3. Save test prompts. Keep a few prompts per GPT, including one hard case, to compare the new version.
4. Pick the new home for each GPT, then rebuild and test it with the saved prompts.
5. Share it with the right people, and tell them where to find it.

To rebuild in TypingMind, follow the migration guide.

• Your team is moving to Claude: Claude Projects.
• Your company runs on Google Workspace: Gemini Gems.
• Your company runs on Microsoft 365: Copilot agents.
• You want a free, self-hosted setup and have an engineer to run it: LibreChat.
