OpenAI has launched its new GPT-4.1 models, including GPT-4.1 mini and nano, designed specifically for coding and instruction following. These multimodal models offer a remarkable 1-million-token context window, allowing them to process extensive text inputs. Competing with Google’s Gemini 2.5 Pro and Anthropic’s Claude 3.7 Sonnet, GPT-4.1 aims to create advanced AI capable of complex software engineering tasks. Despite impressive benchmarks, OpenAI acknowledges challenges with reliability and accuracy, particularly as input size increases. GPT-4.1's pricing is competitive, making it accessible for developers.
