GPT 4.1

GPT-4.1 is the most capable version of the GPT-4.1 series. It emphasizes depth and accuracy, with step-by-step reasoning that outperforms earlier GPT-4 models on complex benchmarks. The model handles large context windows, allowing it to process multi-document workflows, extended conversations, and repository-scale code without losing coherence. Multimodal capabilities mean it can interpret images, diagrams, and screenshots alongside text, producing grounded explanations or structured JSON outputs.

Enterprises use GPT-4.1 as the “heavy” model for high-stakes work: research copilots, business intelligence, advanced coding assistants, and retrieval-augmented systems that require trustworthy logic. While it is slower and more resource-intensive than its smaller siblings, it provides the highest accuracy and reasoning depth in OpenAI’s general model line.
