NVIDIA's open Nemotron 3.5 Lightning has free versions on Vercel AI Gateway and OpenRouter, with $0 input and output. It has a 1M-token context, up to about 65K output tokens and tool calling. No end date has been announced, and the provider may keep prompts and responses from the free version for training.
Poolside’s coding-agent model Laguna S 2.1 has free endpoints on both OpenRouter and Vercel AI Gateway. The free tier offers roughly 256K–262K tokens of context—handy for trying the model before paying for the ~1M-context version.
