Could you build this?
Partial While wrapping Ollama as a reverse proxy is straightforward, managing dynamic OS memory pressure, dynamic Metal buffer resizing, and quantization transitions without crashing local inference requires non-trivial systems programming.
What it would actually take: Built as an HTTP proxy in Python or Go intercepting Ollama's API, calculating prompt token lengths, and inspecting host memory stats via OS syscalls (e.g., mach APIs on macOS or /proc/meminfo on Linux). The difficult challenge is reliably predicting KV cache memory overhead, tuning Metal/CUDA buffer buckets to prevent memory fragmentation, and cleanly orchestrating model reloads or context trims without corrupting ongoing token generation streams.
