Introducing GPT-5.4 Mini and Nano Models
OpenAI unveils GPT-5.4 mini and nano, the latest iterations of their model lineup. The mini version boasts over twice the speed of GPT-5 mini and is tailored for coding and multimodal tasks, while the nano version offers a lightweight and cost-effective solution for simpler tasks.
We’re introducing GPT-5.4 mini and nano, our most capable small models yet.
GPT-5.4 mini is more than 2x faster than GPT-5 mini. Optimized for coding, computer use, multimodal understanding, and subagents.
For lighter-weight tasks, GPT-5.4 nano is our smallest and cheapest https://t.co/cdp5HWtM2M
