LiteLLM: Traffic Mirroring, Batch Completions, and Traffic to Two Providers
0 (0)

21 August 2026

We’re getting ready to launch a self-hosted LLM, and at the testing stage the general idea is to send client requests simultaneously both to the “default production model” like GPT-5.6 and to the model running on our own server. And after getting the responses, we’ll compare them with Phoenix or Opik, and gradually tune our… Read More: LiteLLM: Traffic Mirroring, Batch Completions, and Traffic to Two Providers0… »

We have a server where we’re going to run self-hosted LLMs. We spent quite a while choosing what exactly to use for running the models – vLLM, SGLang, or llama.cpp, and eventually settled on llama.cpp – at least for now.

A few days ago, I ran into an interesting situation with LiteLLM: on the one hand, the metrics showed a lot of errors “from the provider”, while on the other hand, the traces and alerts showed only a single error. I had to dig into it a bit and figure out some nuances of how… Read More: LiteLLM: Metrics, Traces, and Debugging exception_class=”ValueError”0 (0) »

NixOS: Getting Started, Installing Packages, and Configuring the System
0 (0)

5 August 2026

We got a new instance, a hardware server that will run our self-hosted LLMs. The server will run NixOS – not my choice, but the system looks interesting. I’ve been hearing about it for a long time, and now I have a great opportunity to get familiar with it. For now, my part is only… Read More: NixOS: Getting Started, Installing Packages, and Configuring the System0 (0) »
