Big AI release from OpenAI today: GPT-4.1 is officially live, bringing some major upgrades over GPT-4o and GPT-4.5. Here’s what’s new and why it matters: 📖 Massive Context Boost: GPT-4.1 now handles a 1 million token context (previously 128k in GPT-4o). Perfect for deep dives into massive documents, detailed analyses, or extensive codebases. 💻 Coding Excellence: Scored 54.6% on SWE-bench Verified, 21.4% better than GPT-4o and 26.6% ahead of GPT-4.5. Clearly a new gold standard for AI-assisted coding tasks. 🎯 Sharper Instruction Handling: 10.5% better at following complex instructions than GPT-4o, making it a powerhouse for precise, detailed tasks. ⚡️ Faster & Cheaper: GPT-4.1 mini cuts latency nearly in half and costs by a huge 83%. The nano variant is even faster and more affordable, ideal for real-time and low-latency apps. 📅 Data Freshness: Knowledge cutoff updated to June 2024, ensuring more timely, relevant responses. Practical wins here: • Autonomous AI agents get more powerful • Long-form content like legal docs, research papers become much easier to handle • Real-time use cases get significantly cheaper and faster Interesting note: GPT-4 API retires April 30, GPT-4.5 API deprecated by July 14. OpenAI sees GPT-4.1 as the clear upgrade path. Full details below 👇
