[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. --- ## Open these first * Architecture recovery: [RAG Architecture & Recovery](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rag-architecture-and-recovery.md) * Retrieval knobs: [retrieval-playbook.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-playbook.md) * Embedding sanity: [embedding-vs-semantic.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/embedding-vs-semantic.md) * Context stability: [context-drift.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/context-drift.md), [entropy-collapse.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/entropy-collapse.md) * Safety and schema: [prompt-injection.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/prompt-injection.md), [logic-collapse.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/logic-collapse.md) * Boot/deploy: [bootstrap-ordering.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/bootstrap-ordering.md), [predeploy-collapse.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/predeploy-collapse.md) --- ## Core acceptance * ΔS(question, retrieved) ≤ 0.45 * Coverage ≥ 0.70 for the target section * λ convergent across 3 paraphrases × 2 seeds * JSON schema locked for tool calls * Observability of ΔS and λ logged per run --- ## Common Jan breakpoints | Symptom | Likely Cause | Fix | | ------------------------------------- | --------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | First run fails on GPU device | CUDA/Metal init order | [bootstrap-ordering.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/bootstrap-ordering.md) | | Correct snippets but drifting answers | Schema mismatch in local context buffer | [retrieval-traceability.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md), [data-contracts.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md) | | Answers alternate between runs | λ flip, unstable headers | [context-drift.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/context-drift.md) | | JSON parse breaks | Inconsistent serialization in UI layer | [logic-collapse.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/logic-collapse.md) | | Safety refusal hides citations | Missing citation-first prompting | [retrieval-traceability.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md) | --- ## 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.
