GPT‑4.1 is here—and it’s outperforming everything, including GPT‑4o and even 4.5 in some cases. In this video, we dive deep into the new GPT‑4.1 model family, including the Mini and Nano versions. We test their coding capabilities in a real React + Vite flashcard app, compare benchmarks like SWE-bench Verified, Aider’s Polyglot Diff, IFEVAL, and Windsurf, and break down their 1M token context performance. These models are faster, cheaper, and shockingly good. Let’s put them to the test.
