In 2025, OpenAI continues to push the frontier of intelligent systems with the release of GPT-4.1—a refined, multimodal upgrade to its groundbreaking GPT-4 model. Faster, more stable, and visually smarter, GPT-4.1 is designed for users who demand high performance, reliable results, and seamless tool integration. Whether you're coding, writing, researching, or automating, GPT-4.1 is ready to assist.
Even better, it’s available directly through Chat4O’s GPT-4.1 model page—no API key or coding needed.
What Is GPT-4.1?
GPT-4.1 is OpenAI’s improved successor to the original GPT-4, launched exclusively for ChatGPT Plus users and API customers. It’s a multimodal model, meaning it can process both text and image inputs. GPT-4.1 also comes with tool access, allowing it to use Python, the web browser, and image analysis—all to produce more accurate, context-aware answers.
It's not just smarter—it’s also more usable, making it ideal for real-world applications.
What's New in GPT-4.1?
Compared to its predecessor, GPT-4.1 offers several important enhancements:
- Stability: Fewer crashes, better session memory, and smoother interaction
- Speed: Optimized inference time, especially with tool use
- Visual IQ: More precise and descriptive image understanding
- Reasoning: Better handling of multi-step prompts and logical chains
- Safety: Improved alignment and lower hallucination rate
This makes GPT-4.1 not only a more powerful AI but also a more trustworthy one.
