NVIDIA opens free Gemma 4 31B API

This is more distribution than breakthrough: the model launch already happened, and NVIDIA is mainly removing friction for developers who want to benchmark or prototype against it.

• –The free trial endpoint lowers the barrier to entry for teams that do not want to manage weights, quantization, or local GPU capacity
• –NVIDIA’s own docs frame it as a trial service, so it reads as prototyping access rather than a production-grade free tier
• –Gemma 4 31B is positioned for reasoning, code generation, agentic workflows, and multimodal inputs, which makes it a practical eval target for app builders
• –If the rumored 40 rpm limit holds, this is useful for experimentation but not for serious throughput or production traffic
• –The bigger signal is ecosystem support: Google’s open model now ships with first-party access through NVIDIA, which broadens where developers can adopt it
