# Qwen Model Policy for JackAILocal

JackAILocal uses Qwen3.5 as the practical default family and Qwen3.6-27B as a power profile for high-end machines.

## Default pack

The default pack is not the ceiling. It is a sensible offline default designed to run on ordinary laptops without forcing the user to understand model size, quantization, VRAM, context length, or backend selection.

Default candidates:

- Qwen3.5 2B for low-spec machines.
- Qwen3.5 4B for normal laptops.
- Qwen3.5 9B as the default smart offline assistant.
- Qwen3.5 27B when the machine has enough memory.

## Power pack

Qwen3.6-27B is included as a power profile candidate.

Use it when:

- the machine has RTX 3090-class hardware or better;
- the machine has roughly 24 GB VRAM or enough RAM for a quantized fallback;
- the user selected the Power package;
- the use case benefits from stronger coding, reasoning, vision, or agentic workflows.

Do not use Qwen3.6-27B as the default for ordinary laptops.

## Hackathon rule

The hackathon rule is not "Qwen 9B only". The rule is that the Space must be powered by models under the 32B parameter limit. Qwen3.6-27B is eligible by parameter count. Avoid ambiguous models whose published parameter count is over the limit.

## Backend policy

Qwen3.5 models can be used through Ollama when the selected tag is available. They can also be provided as GGUF files for llama.cpp.

Qwen3.6-27B is packaged through its Ollama model reference when that model is selected. A GGUF quantization may also be used for an explicitly supplied local `llama.cpp` server if the artifact and hash are pinned in the manifest.

## Context policy

Do not default to the maximum native context. Long contexts increase memory usage and can cause out-of-memory errors.

USB defaults:

- normal profiles: 4K to 8K context;
- power profiles: 8K to 16K context;
- long-context mode: explicit advanced option only.

## Product wording

Use this wording:

> JackAILocal ships with a practical Qwen3.5 default pack for ordinary laptops, then unlocks Qwen3.6-27B and other power models when the detected machine can run them.

Do not say:

> JackAILocal is limited to Qwen 9B.
