[Jan](https://jan.ai) is a desktop-native inference environment that allows you to run local LLMs with a polished UI, cross-platform support, and tight integration with quantized model formats.
While easier to use than CLI runtimes, Jan inherits common problems: unstable context handling, schema drift, citation loss, and device-specific crashes.
This page gives WFGY-based fixes to stabilize Jan deployments.

## Fix in 60 seconds

1. **Run warm-up**: issue a small dummy query to stabilize device kernels.
2. **Schema enforce**: lock JSON outputs for tools and citations.
3. **Trace citations**: enforce cite-then-explain.
4. **Measure ΔS and λ**: if ΔS ≥ 0.60, rebuild index with proper embedding metric.
5. **Watch entropy**: reset conversation memory after 4k–8k tokens or entropy rise.

## Diagnostic prompt (copy-paste)

```txt
I am using Jan to run a local GGUF/GGML model.
Question: "{user_question}"

Return:
- ΔS(question, retrieved)
- λ across paraphrases and seeds
- JSON schema compliance
- Which WFGY fix page to open if ΔS ≥ 0.60
```
