GPT-4.1

openai/gpt-4.1

GPT-4.1 is OpenAI's flagship non-reasoning model in the GPT-4.1 series, released in April 2025 alongside GPT-4.1 mini and nano, with text and image input and text output. OpenAI positions it for instruction following, tool calling and coding, with improved long-context comprehension across its 1M-token window and low latency because it skips a separate reasoning step. Pick it over the mini and nano tiers when output quality matters more than speed; OpenAI suggests GPT-5-class models for the most complex tasks.
