OpenAI: GPT-5 Nano

The OpenAI GPT-5 Nano is equipped to handle diverse input modalities including text, images, and files, with a substantial context length of 400,000 tokens, making it versatile for complex tasks that require extensive data processing. It supports reasoning and tools integration, enhancing its problem-solving capabilities. However, the model does not offer structured output or open weights. When considering cost-effectiveness and performance, the GPT-5 Nano may be a good fit for those who need to process large volumes of diverse input data with moderate computational resources. Its blended benchmark score of 32.1 indicates solid performance across various benchmarks, though its coverage remains at full scope only in one benchmark as of August 13th, 2026. Given the pricing at $0.05 per million input tokens and $0.4 per million output tokens, it strikes a balance between cost and functionality for businesses or researchers willing to invest in its capabilities.
