Could you build this?
Partial A basic LLM router/proxy is easy to vibe-code, but autonomous online post-training and continuous RL/eval loops based on enterprise telemetry require advanced ML infra.
What it would actually take: A basic implementation is a proxy API in Rust or Go that routes prompts based on cost and heuristics. The complex component is the autonomous post-training feedback loop: curating production prompt/completion logs, synthesizing evaluation pairs, and orchestrating distributed LoRA fine-tuning and DPO jobs on open-source weights (vLLM/DeepSpeed). This demands seasoned ML infrastructure engineers and GPU cluster management.
