GPT-4.1 is HERE! OpenAI is BACK!

# OpenAI Launches GPT-4.1: A Faster, Cheaper, and More Capable API-Only Model

OpenAI just made a significant announcement that’s shaking up the AI landscape: GPT-4.1 is officially here, and it’s exclusively available through their API. This new model isn’t just a minor upgrade—it outperforms GPT-4.0 in almost every way while being substantially cheaper. Even more surprising, it’s actually surpassing the recently released GPT-4.5, which OpenAI now plans to deprecate.

## Three models for different needs

The GPT-4.1 family includes three distinct models:

– **GPT-4.1** – The flagship model
– **GPT-4.1 Mini** – A balanced option that’s emerging as the standout performer
– **GPT-4.1 Nano** – An ultra-fast, incredibly affordable option

All three models share one game-changing feature: a massive 1 million token context window. This addresses one of OpenAI’s biggest competitive disadvantages and comes with no additional cost penalty—you simply pay for the tokens you use.

## Major improvements in key areas

OpenAI has focused on enhancing capabilities that matter most to developers:

### Better at coding
GPT-4.1 scores 54.6% on the SWE-Verified benchmark, representing a 21.4% improvement over GPT-4.0 and a 26.6% improvement over GPT-4.5. According to the CEO of Windsurf (an early partner), GPT-4.1 scores 60% higher on their internal coding benchmarks and is 30% more efficient at tool calling.

The model is particularly good at creating code “diffs” instead of rewriting entire files, which saves both time and money. It’s also significantly better at frontend development, creating more functional and visually appealing interfaces.

### Superior instruction following
On OpenAI’s instruction following benchmark, GPT-4.1 scored 49% on hard instructions compared to just 29% for GPT-4.0. This means the model is much better at precisely following complex, multi-step directions—no more having to beg the AI to
