Running Research Experiments on DGX Spark: Why Smaller VRAM Can Be Cheaper for Iterative AI — Why H100s are overkill for iterative research — and how DGX Spark at $0.65/hr lets you run 5–8x more experiment variants for the same budget.
Run AI Agents Locally: OpenClaw, Local LLMs, and Why the Cloud Should Be Yours — Why building AI agents on API calls is expensive and insecure — and how running OpenClaw with local LLMs on Spark Cloud keeps your data private while cutting costs by half.
Does Size Matter? Just Because a Model Fits Doesn’t Mean It Runs Well — Why fitting an LLM in memory is not the same as running it well — and what teams should optimize for instead when choosing models and infrastructure.
Why AI Agents Need Their Own Cloud — Why the next bottleneck for AI agents is not model quality, but the environment they run in — memory, tools, permissions, and persistent infrastructure.
Why Every Company Will Need an AI Cloud — Why AI is shifting from a chatbot tab into company infrastructure — and why every business will eventually want its own dedicated AI environment.
