OpenAI Is Retiring Custom GPTs — and It Tells You Everything About Where AI Platforms Are Going
OpenAI has announced that custom GPTs — the personalized mini-apps built on top of ChatGPT — are being retired from the creation interface. If you built a custom GPT, this is the end of the road for that particular platform feature.
But the bigger story isn't about GPTs themselves. It's about what this decision reveals about the economics of AI platforms and the tension between open ecosystems and walled gardens.
The Rise and Fall of Custom GPTs
When OpenAI launched custom GPTs in late 2023, it was positioned as the beginning of an app store for AI. Anyone could build a custom chatbot with specific instructions, knowledge files, and capabilities. There was a GPT Store. There were promises of revenue sharing for popular GPTs.
The reality didn't match the vision. Most custom GPTs were trivial — wrappers that added a system prompt to ChatGPT. The few genuinely useful ones (coding assistants, writing tools, data analyzers) were largely duplicative of features that ChatGPT itself was evolving to include natively.
The GPT Store never became the App Store equivalent OpenAI hoped for. Discovery was poor, monetization was absent, and users generally preferred to just talk to ChatGPT directly rather than route through a custom GPT.
Why GPTs Failed
Several factors killed custom GPTs:
Base model improvement. As GPT-4 and later models got smarter, the gap between "ChatGPT with a custom prompt" and "ChatGPT with good instructions" narrowed. Why use a custom coding GPT when base ChatGPT is already an excellent coding assistant?
No real monetization. OpenAI promised a revenue-sharing program but delivered something complicated and limited. Without meaningful income, creators had no incentive to invest in high-quality GPTs.
Competition from agents. The industry moved from "custom chatbots" to "AI agents" — systems that don't just chat but take actions. A custom GPT that answers questions about your product is less useful than an agent that can actually interact with your product's API.
Platform lock-in concerns. Building a business on someone else's platform is always risky. OpenAI's decision to retire GPTs validates this concern. Creators who invested time in custom GPTs now have nothing to show for it.
What Replaces GPTs?
The feature isn't disappearing entirely — it's being absorbed into the base product. ChatGPT's custom instructions, projects, and memory features now cover most of what custom GPTs offered. The shift is from "build a separate mini-app" to "configure your main ChatGPT experience."
This mirrors a broader pattern in AI platforms. Google's Gemini is following a similar path — fewer separate tools, more integrated capabilities. The "app store for AI" model hasn't worked because AI isn't like mobile apps. You don't need a separate app for each task when one model can handle all of them.
The Platform Lesson
For developers, the retirement of GPTs is a cautionary tale about building on AI platforms:
Don't build your business on someone else's AI platform. If OpenAI can retire GPTs, they can retire any feature. Your custom GPT, your API integration, your plugin — none of it is permanent.
Open-source is the hedge. Tools like Ollama, vLLM, and open-weights models (Llama, Qwen, DeepSeek) give you control over your AI stack. You can't be deplatformed if you're running the model yourself.
Agents are the future, not chatbots. The energy in the AI ecosystem has moved from "custom chatbots" to "autonomous agents." Frameworks like LangGraph, CrewAI, and the Strands SDK represent the next platform layer — and they're more open than GPTs ever were.
What This Means for the App Store Dream
The "AI app store" idea isn't dead, but it's evolving. Instead of custom chatbots, the next iteration will likely be:
- Agent marketplaces where you buy or subscribe to AI agents that perform specific tasks (bookkeeping, customer support, data analysis)
- Model fine-tuning services where you get a custom-tuned model for your domain
- Tool/integration ecosystems where the value is in what the AI can connect to, not how it talks
OpenAI's retreat from GPTs is an admission that the first generation of AI platforms didn't work as expected. The next generation is being built right now — and this time, developers are paying attention to who controls the platform.
