OpenAI Is Deprecating Custom GPTs. Here's the Migration Path.
On April 22, 2026, OpenAI introduced Workspace Agents — Codex-powered AI agents that run inside ChatGPT, connect to Slack, Salesforce, Gmail, and a growing list of enterprise tools, and execute multi-step workflows on a schedule. OpenAI's own framing called them "an evolution of GPTs."
The honest version is more pointed. Custom GPTs are being deprecated for Business, Enterprise, Edu, and Teachers accounts. A one-click conversion tool is reportedly on the way. Workspace Agents were free until May 6, 2026, after which credit-based pricing kicked in. Individual users on Plus, Pro, and Free plans can keep their custom GPTs for now, but every new feature is shipping into Workspace Agents. Custom GPTs are in maintenance mode.
If you built one and started thinking of it as your product, this is the moment to take a hard look at what you actually own.
What Changed
Workspace Agents are a new architecture for the same idea, with the lock-in made explicit.
The agent lives inside ChatGPT and can't be white-labeled or moved to your own domain. Pricing is credit-based, layered on top of the $20-per-user-per-month Business plan minimum. And the resale story is gone. Your audience or your agency client has to buy their own ChatGPT seat to access whatever you built.
That's the upgrade. More integrations, more capability, less ownership.
What Custom GPTs Always Were
Anyone who built a custom GPT and treated it as their product was making an assumption OpenAI never confirmed. The custom GPT lived inside ChatGPT, on OpenAI's runtime, behind OpenAI's login wall. The user was always renting access to a hosted feature.
Workspace Agents make that arrangement honest. The format is more powerful. The dependency is also deeper. Every agency or coach who treated custom GPTs as a productized layer of their offering now has a forced migration in front of them.
What This Means for Agencies
If you run a marketing agency, especially one serving a vertical niche, and you've been packaging custom GPTs into your client deliverables, the question worth asking is whether the GPTs are sellable assets or just features of a product you happen to use.
If they live inside ChatGPT, they're features. They're billed by OpenAI, accessible only through ChatGPT, and now on a deprecation timer for Business plans. Your client may be paying you for "AI-powered marketing tools," but the actual asset belongs to OpenAI.
That's a fragile foundation for an agency offering.
What This Means for Coaches and Knowledge Experts
For coaches, consultants, framework creators, and educators who built custom GPTs as part of their digital offering, the problem is the same in different clothes. Your audience can't access your GPTs without their own ChatGPT subscription. The GPT itself is hosted somewhere you don't control. And the format is being phased out.
The work you put into your custom GPT sits on OpenAI's runtime. When OpenAI changes the format, your asset changes with it. You don't get a vote.
The Migration Path
The obvious move is to get the work out of someone else's runtime and into something you actually own. That's the case for FormWise.
A FormWise CoPilot does what a custom GPT does. It runs on a system prompt, accepts conversation starters, references uploaded documents, and returns chat-style outputs. The difference is what surrounds it.
You can white-label the CoPilot under your brand, embed it on your own site, and sell access however you want. The asset belongs to you. The deployment surface belongs to you. So does the pricing model.
The migration itself takes about ten minutes. Paste your GPT instructions into the first node of the FormWise Agent Builder, add your conversation starters, and pick a model. Turn on web search if the agent needs it. That's it.
From there, you decide where it lives. You can put it inside a Toolset you sell to clients, embed it on your site, or paywall it as a standalone product. Outputs come back as downloadable Artifacts that end users can edit and refine, which means the experience feels like real software instead of a chatbot response.
What to Do Now
If you've built custom GPTs for your clients or your audience, the work is worth keeping. The runtime isn't.
Pull the system prompt out of ChatGPT. Save your conversation starters. Save any reference documents you uploaded. Then walk through the migration in FormWise and rebuild the agent as a CoPilot you own.
