openai: OpenAI GPT-4.1 Nano

For tasks that demand low latency, GPT-4.1 nano is the fastest and cheapest model in the GPT-4.1 series. It delivers exceptional performance at a small size with its 1 million token context window, and scores 80.1% on MMLU, 50.3% on GPQA, and 9.8% on Aider polyglot coding – even higher than GPT-4o mini. It's ideal for tasks like classification or autocompletion.
