Overview

Freshness note: Model capabilities, limits, and pricing can change quickly. This profile is a point-in-time snapshot last verified on February 15, 2026.

GPT-4.1 is a versatile long-context model for mixed tasks across analysis, generation, and workflow automation. OpenAI retired GPT-4.1 from ChatGPT on February 13, 2026 while leaving API availability unchanged, so it now fits better as a legacy compatibility option than as a current public-facing default.

Capabilities

The model handles long-document synthesis, instruction-following, and mixed business/engineering tasks well. It is effective for structured outputs and assistant behaviors where consistency is more important than extreme reasoning depth.

Technical Details

GPT-4.1 emphasizes broad compatibility and long context usage. It supports multimodal-style workflows in API ecosystems that allow mixed input types, with strong utility in enterprise document-heavy pipelines.

Pricing & Access

Accessible via OpenAI API products and partner environments that surface OpenAI models. Pricing and feature sets can vary, so teams should validate current plan details from official OpenAI documentation.

Best Use Cases

Best for enterprise copilots and compatibility-sensitive API systems that still rely on GPT-4.1 behavior. For new default deployments, OpenAI’s GPT-5 family is the more current path.

Comparisons

Compared with GPT-5.3, GPT-4.1 is the older general-purpose route in OpenAI’s lineup. Compared with GPT-5.4, it is less aligned with the current premium path. Compared with Gemini 2.5 Pro, choice depends on multimodal needs, cost targets, and integration context.
