GPT-5.4 Nano is Here. Here's What Indie Hackers Need to Know
OpenAI just dropped two new models that should be on every indie hacker’s radar: GPT-5.4 mini and GPT-5.4 nano, announced March 17, 2026. If you’re building AI-powered products, these aren’t just incremental updates — they’re a meaningful shift in what you can ship at what price point. The Numbers That Matter Here’s the quick rundown: GPT-5.4 mini: $0.75 per 1M input tokens, $4.50 per 1M output. 400k context window. 2x faster than GPT-5 mini. Approaches GPT-5.4 on SWE-Bench Pro (54.4% vs 57.7%) and GPQA Diamond (88.0% vs 93.0%). GPT-5.4 nano: $0.20 per 1M input tokens, $1.25 per 1M output. The cheapest GPT-5.4 variant yet. Built for classification, data extraction, ranking, and simpler subagent tasks. For context, GPT-5.4 nano costs less than a fifth of GPT-5.4 while handling a surprising range of tasks. If you’ve been hesitating to add AI features because of API costs, this changes the math. ...
