# rlx-models-core
Shared config, weight loading, compile profiles, and packed GGUF prefill helpers for RLX model crates (published on crates.io as **`rlx-models-core`**; import as `rlx_core`).
**Version 0.2.1** adds packed GGUF support:
| [`packed_gguf_compile_guard`](src/flow_bridge.rs) | Metal `RLX_DISABLE_MPSGRAPH`, MLX `RLX_MLX_MODE=eager` during compile |
| [`compile_options_for_packed_gguf_prefill_with_profile`](src/flow_bridge.rs) | Fusion off on wgpu/CUDA/ROCm for `FusedResidualRmsNorm` gaps |
| [`packed_gguf_execution_device`](src/flow_bridge.rs) | Route MLX/wgpu/CUDA packed prefill to CPU when needed |
Used by `rlx-llama32`, `rlx-qwen3`, `rlx-gemma`, and `rlx-minicpm5`.
