While often discussed for privacy, running models on-device eliminates API latency and costs. This allows for near-instant, high-volume processing for free, a key advantage over cloud-based AI services.

Daytona initially built dev environment automation for human engineers but quickly pivoted. Early feedback from AI agent builders revealed that agent infrastructure has fundamentally different requirements for speed, statefulness, and scale—a non-obvious distinction at the time that proved critical to finding product-market fit.

While total generation time might be similar to API calls, local models offer a superior user experience by starting responses almost immediately. This eliminates the unpredictable network latency and random slowdowns common with APIs, making the interaction feel smoother and more reliable.

By building their own data centers, Railway achieves a payback period of just three months on hardware costs versus renting from hyperscalers. This dramatic cost advantage is a strategic enabler for offering resource-intensive services, like parallel AI agent execution, at a viable price.

Instead of using local machines like Mac Minis, host client agents in isolated cloud virtual machines (e.g., via Orgo). This provides a secure, sandboxed environment and allows you (and your own management agent) to remotely access, debug, and update all client agents from a single platform, making fulfillment vastly more efficient.

While cloud hosting for AI agents seems cheap and easy, a local machine like a Mac Mini offers key advantages. It provides direct control over the agent's environment, easy access to local tools, and the ability to observe its actions in real-time, which dramatically accelerates your learning and ability to use it effectively.

To operate thousands of GPUs across multiple clouds and data centers, Fal found Kubernetes insufficient. They had to build their own proprietary stack, including a custom orchestration layer, distributed file system, and container runtimes to achieve the necessary performance and scale.

Instead of giving an LLM hundreds of specific tools, a more scalable "cyborg" approach is to provide one tool: a sandboxed code execution environment. The LLM writes code against a company's SDK, which is more context-efficient, faster, and more flexible than multiple API round-trips.

The DBOS project, co-founded by Stonebraker, argues operating systems primarily manage data at scale. Replacing core OS components (like the file system and scheduler) with a database engine can lead to faster performance, built-in high availability, and transactional guarantees for system operations, with "really no downside."
