Why are AI pipelines still rebuilding everything when only one thing changed?

aimake 2.0 is an open-source incremental build system for AI/ML pipelines, addressing the inefficiency of rebuilding entire pipelines when only a small change occurs. It uses SHA-256 content fingerprints to identify changes, building a dependency graph to reuse cached components and rebuild only affected steps. Key features include parallel builds, content-addressed caching, cost estimation, interactive TUI, web dashboard, Python/TypeScript SDKs, and plugins for Hugging Face, W&B, DVC, Docker, and Ollama.
