GPT-4.1 is HERE! OpenAI is BACK!

# OpenAI’s GPT-4.1: The Model That Makes GPT-4.5 Obsolete

OpenAI just dropped a bombshell on the AI community with the release of GPT-4.1, a new model family that outperforms its predecessors while being significantly cheaper. And here’s the kicker – it’s only available via API. Let’s dive into what makes this release so significant for business users and developers.

## The GPT-4.1 Family: Three Tiers of Power

OpenAI is introducing three versions of GPT-4.1:
– **GPT-4.1**: The flagship model
– **GPT-4.1 Mini**: The standout performer in the family
– **GPT-4.1 Nano**: The first “nano” model in OpenAI’s history

All three models come with a massive **1 million token context window** – without charging extra for that extended context, unlike competitors who typically upcharge for longer contexts.

## GPT-4.5 Gets Sidelined

In a surprising twist, OpenAI announced they’re deprecating GPT-4.5 (released just weeks ago) in favor of 4.1. Why? According to Kevin Wheel, OpenAI’s Chief Product Officer, they simply need the GPUs. GPT-4.5 was resource-intensive, and 4.1 delivers comparable performance at much lower cost and latency.

Developers using GPT-4.5 have three months to transition before it’s turned off on July 14, 2025.

## Performance That Matters for Business

The benchmarks are impressive:

– **Coding**: GPT-4.1 scores 54.6% on SWE-Bench Verified, a 21.4% improvement over GPT-4.0 and 26.6% over GPT-4.5
– **Instruction following**: 10.5% increase over GPT-4.0
– **Long context understanding**: State-of-the-art results on processing video content

What’s particularly noteworthy for enterprise users is how effectively these models handle document understanding:
