BREAKING NEWS! 🚀 OpenAI’s GPT-4.1 API Models Are Here – Built for Developers OpenAI has launched GPT-4.1, GPT-4.1 Mini, and GPT-4.1 Nano—models engineered for real-world coding, instruction following, and long-context tasks.  🔧 Key Dev Features • Coding Performance: GPT-4.1 scores 54.6% on SWE-bench Verified, outperforming GPT-4o by 21.4% and GPT-4.5 by 26.6%. It handles diffs more precisely, reduces unnecessary edits, and adheres to formatting constraints.  • Long Context: All models support up to 1 million tokens—8x more than GPT-4o—enabling full repo analysis and deep document comprehension.  • Instruction Following: Improved multi-step reasoning and formatting accuracy, with a 10.5% gain over GPT-4o on MultiChallenge.  • Latency & Cost: GPT-4.1 is 40% faster and 80% cheaper per query than GPT-4o. Mini and Nano versions offer even greater speed and affordability.  🧠 Model Lineup Model Context Window Use Case Cost per 1M Tokens GPT-4.1 1M tokens Production-grade coding & agents $2.00 input / $8.00 output GPT-4.1 Mini 1M tokens Balanced performance, cost-sensitive apps $0.40 / $1.60 GPT-4.1 Nano 1M tokens Ultra-fast, lightweight tasks $0.10 / $0.40 🛠️ Access & Tools • API Only: Available via OpenAI API and Playground—ChatGPT remains on GPT-4o.  • Prompting Guide: Optimized prompts for agentic coding workflows.  • Benchmarks & Pricing: Detailed comparisons and cost breakdowns.
