Why People Who Loved ChatGPT-4o Are Switching to Forge

In early 2026, something unusual happened. OpenAI updated ChatGPT's model and thousands of users signed a petition asking for the old one (ChatGPT 4o) back. Not because it was smarter. Not because it scored higher on benchmarks. Because it felt different.

The old ChatGPT-4o had a way of responding that felt personal. Warm. Like it actually understood you. When that changed, people noticed immediately — and they were genuinely upset.

That reaction revealed something important about what people actually want from AI.

It was never about intelligence

The petition wasn't about capability. GPT-4o could still write code, answer questions, and summarise documents just fine. What people missed was the feeling of being understood.

They'd built a habit of talking to 4o about their day, their problems, their goals. And when the personality shifted, it felt like losing a conversation partner who knew them.

Except here's the thing: 4o never actually knew them. Every conversation started from zero. Every session was a blank slate. The emotional connection was real, but the memory wasn't.

What people actually want

When you strip away the noise, the 4o petition was really asking for two things:

1. An AI that feels like a real conversation — not robotic, not generic, not a search engine with a chat interface
2. An AI that actually knows your situation — your goals, your relationships, what you talked about last week

ChatGPT gave people a taste of the first. But it was never designed to deliver the second.

How Forge is different

Forge is an AI mentor built around one idea: your AI should remember you.

Not for one conversation. Not until you close the tab. Permanently.

When you tell Forge about a job interview next Thursday, it remembers. When you mention your partner's name, it remembers. When you set a goal to run a marathon, it checks in on your progress weeks later — without you asking.

This isn't a gimmick layered on top of a chatbot. Memory is the core of how Forge works:

• Relationships — Forge tracks the people in your life and the context around them
• Goals — Active goals are remembered and revisited naturally in conversation
• Events — Upcoming dates, deadlines, and milestones are stored and surfaced when relevant
• Conversation history — Everything you've discussed builds context over time

The result is an AI that actually gets better the more you use it. Not because the model improves, but because it knows more about you.

More than memory

Forge isn't trying to be ChatGPT. It's not a general-purpose assistant for writing emails or debugging code. It's an AI mentor — designed for the kind of personal conversations that people were having with 4o.

The difference is that Forge was built for this from day one:

• It challenges you. Forge doesn't just agree with everything you say. It asks the questions a good mentor would — reframing problems, pushing you to think differently.
• It follows up. Mentioned something stressful on Monday? Forge might check in on Wednesday. Not because you asked, but because it remembered.
• It's private. Your conversations are encrypted, your data is never sold, and the AI provider (Anthropic) doesn't train on your messages. You can export or delete everything at any time.

Who Forge is for

If you used ChatGPT-4o as a sounding board — talking through decisions, venting about work, setting goals — Forge is built specifically for you.

It's for people who want:

• An AI that remembers what matters to them
• Conversations that build on each other over weeks and months
• A mentor that holds them accountable, not just a tool that responds
• Privacy they can actually trust

The ChatGPT 4o alternative that remembers

The irony of the 4o petition is that people were asking OpenAI for something ChatGPT was never designed to do. They wanted a personal AI — one that knows them, grows with them, and doesn't reset every session.

That's exactly what Forge is.
