GPT-4.1 can interpret both text and images in a single conversation, allowing it to describe visuals, analyze charts, or even understand handwriting. It’s like chatting with an AI that can see.
It remembers up to 128,000 tokens — equivalent to an entire book — meaning it can analyze long documents, hold more coherent conversations, and remember much more from earlier in your interaction.
GPT-4.1 shows major improvements in logic, math, and code generation. It’s far better at step-by-step problem-solving and understanding nuanced questions than previous versions.
If you’re using ChatGPT with memory turned on, GPT-4.1 can remember your name, preferences, and past tasks, making it feel more like a personalized assistant than ever before.
When used in ChatGPT Pro, GPT-4.1 can integrate tools like a code interpreter, image generation, and web browsing — meaning it can run code, look up current info, and even generate graphics, all on the fly.
