After Musk's Grok canceled the $150 monthly giveaway, the only official platform now offering free access is Google Cloud Vertex.
Google Cloud Vertex currently provides new registered users with a $300 usage credit, which can be used in Roo Code to access the latest and most advanced Gemini 2.5 series models.
Additionally, Cloud Run under Google Cloud Vertex now fully supports NVIDIA L4 GPUs as of today, which can be used with the aforementioned credit.
Cloud Run supports GPU acceleration directly in five regions, suitable for real-time AI inference, batch tasks, and model fine-tuning. For details, refer to the official homepage.
Prerequisites: A valid new Google account with an activated Google Cloud billing account.
However, using the web version of Google Cloud Vertex can be quite complex, requiring configuration of project permissions and other settings, which can be confusing. Below, we introduce a relatively simpler, more programmatic configuration method: the command line tool Google Cloud CLI.
