New Delhi, March 18 -- OpenAI has launched its new GPT-5.4 Mini and Nano models to its free users. Just weeks after launching the more powerful GPT-5.4 model, the AI startup's new GPT-5.4 Mini model is positioned as a 'smaller, cheaper' alternative in cases where speed and cost matter the most.

GPT-5.4 Mini is said to come with improved performance across a range of tasks like coding, reasoning, multimodal understanding and tool use. The model is said to be running over 2 times faster than its predecessor and have close performance to the GPT-5.4 model on certain benchmarks like SWE-Bench Pro and OSWorld-Verified.

Meanwhile, GPT-5.4 Nano is positioned as the smallest and cheapest version of GPT-5.4 for areas where speed and cost are imp...
