# trip-optimizer-mutator

MLX LoRA adapter for **Qwen3-4B-Instruct-2507** that generates targeted, structured
itinerary mutations for [trip-optimizer](https://github.com/michaelpersonal/trip-optimizer).

## Task

Given a trip profile, current plan, optimization goal, and constraints, the model
outputs a scoped RFC 6902 JSON Patch proposal — one change at a time.
trip-optimizer applies the patch deterministically and validates the result.

Input task field: `mutate_plan`

Supported mutation types: `swap_activity`, `upgrade_meal`, `reorder_day`,
`simplify_day`, `time_adjust`, `clarify`

## Usage with mlx-lm

```bash
pip install mlx-lm
```

```python
from mlx_lm import load, generate

model, tokenizer = load(
    "Qwen/Qwen3-4B-Instruct-2507",
    adapter_path="esc511/trip-optimizer-mutator",
)
```

## Usage with trip-optimizer

```bash
# After installing trip-optimizer
trip-optimizer setup   # pulls via Ollama
```
