## Summary

Recent updates to the Oh My Pi (omp) assistant tool require users to modify their custom model configurations in `models.yml` for version 18.2.7 and later. Users must rename custom providers from "local" to a unique name to avoid conflicts with omp's new built-in local provider for on-device models. Additionally, users running Qwen 3.8 models must add `qwenTemplateReasoningEffort: true` to the model's compatibility block to prevent the chat template from defaulting to maximum thinking effort.

The update also affects how omp handles inference servers like vLLM, llama.cpp, LM Studio, Ollama, and SGLang. To prevent omp from falling back to hosted models when local servers fail, users can implement an allowlist using the `enabledModels` setting in `config.yml`. A Python logging script can be used to debug and inspect the exact request payloads omp sends to these custom backends.

## Key points

- Users must rename custom local providers to avoid conflicts with the new built-in local provider in omp 18.2.7.
- Qwen 3.8 configurations require the qwenTemplateReasoningEffort parameter to prevent thinking effort from defaulting to maximum.
- An allowlist in config.yml can restrict omp to local models and prevent accidental fallbacks to paid hosted APIs.

## Why it matters

This update is critical for developers and enthusiasts running local AI models on personal hardware, ensuring their custom routing, thinking budgets, and privacy guardrails remain intact.
