GPT-4.1 has revealed GPT-4.1, a model that shatters coding benchmarks with impressive gains over its predecessors. The new standard scored 54.6% on SWE-bench Verified, demolishing GPT-4o by 21.4 percentage points and GPT-4.5 by a whopping 26.6%. Yeah, that’s right—this thing was built specifically to crush coding tasks. Developers collaborated with OpenAI to optimize it for real-world utility, and it shows.

A coding revolution that doesn’t just impress on paper—it actually delivers what developers need.

The improvements aren’t just about raw performance. GPT-4.1 follows diff formats more reliably, letting devs output only changed lines instead of entire files. Less bloat, more efficiency. It’s also gotten way better at following instructions—10.5% better than GPT-4o on the MultiChallenge benchmark. Crazy what happens when you actually listen to what people want, right?

Context handling got a massive upgrade too. One million tokens? That’s 8 times what GPT-4o could handle. Imagine processing entire codebases in one go. No more chopping things up into confusing bits. The model also makes fewer unnecessary edits and sticks to the structure you specify. Finally.

Code generation capabilities jumped considerably, especially for frontend work and agentic problem-solving. It’s better at exploring repositories, writing tests, and producing code that actually works. Novel concept! The model supports precise code wrapping with various options and handles a massive 32,768 output tokens, double what GPT-4o offered. This dramatic reduction in extraneous code edits from 9% to 2% represents a significant quality improvement for developers. The model excels when using apply_patch tool for making precise code modifications with a unique diff format.

Integration with tools is smoother now. GPT-4.1 uses the API’s dedicated ‘tools’ field more effectively, ensuring consistent tool usage during complex tasks. The knowledge cutoff extends to June 2024, so it’s working with fresher information.

For developers tired of half-baked solutions, this upgrade feels substantial. Better instruction following, improved formatting adherence, and enhanced reasoning capabilities make GPT-4.1 a considerable leap forward. It’s designed to be helpful, not just impressive on paper. And in the coding world, that’s what matters.
