NVIDIA: Nemotron 3.5 Super VL (free)

Nemotron 3.5 Super VL (free) is an NVIDIA model that accepts text, image, and video input and returns text. It offers a 1,000,000-token context window and allows up to 131,072 tokens per completion, which leaves room for long documents, lengthy transcripts, or large batches of visual material in a single request. It supports tool calling and a reasoning mode. The listing does not confirm structured output support or whether the weights are open, so verify both before depending on them. The main reason to shortlist it is cost: input and output are both priced at zero. That makes it a practical candidate for experimentation, high-volume multimodal workloads, or prototyping agent workflows with tools. Its blended benchmark score of 40.1 rests on a single independent benchmark, so its relative standing is not well established. Teams should run their own evaluations against paid alternatives before committing production work to it.
