# Version 2 Release Notes

Version 2 is one multi-task LoRA adapter, distributed as matching PEFT and GGUF
representations. It replaces the current adapter for new integrations while the
v1 GGUF remains available for rollback.

## Changes

- Improves Food-101 strict accuracy from 86.80% to 87.60% on 500 held-out images.
- Adds experimental visible-ingredient and rough-gram JSON output.
- Keeps nutrition calculation outside the model through USDA FoodData Central
  mappings and application rules.
- Preserves rank 8, alpha 16, and the seven original target-module families.
- Validated with the existing Unsloth `UD-Q4_K_XL` base and `mmproj-F16.gguf`.

## iOS Migration

Update only the adapter download filename to:

```text
beforeat-food-nutrition-vision-lora-v2-f16.gguf
```

Continue to reuse the existing base GGUF and projector, and apply the adapter at
scale `1.0`. Do not load the historical v1 adapter at the same time.
