GPT-4.1
The "Context King"—Optimized for massive document analysis and reliable instruction following.
About the Model
GPT-4.1 is the 2025/2026 "reliability update" to the GPT-4 family. While newer models focus on "thinking," GPT-4.1 focuses on precision and context. It features a standardized 1-million-token context window and is significantly cheaper and faster than the older GPT-4o. It is preferred by developers who need a model that "just follows the rules" without over-explaining.
