## 🔥 **Bonus Features (Beyond Proposals)**


MLMF delivers **8 additional enterprise capabilities** not in the original proposals:

### **1. Model Conversion System**

```rust
use mlmf::conversion::{convert_model, ConversionFormat};

// Direct format-to-format conversion with batch processing
convert_model(
    Path::new("model.safetensors"),
    Path::new("model.onnx"),
    ConversionFormat::ONNX,
    options,
)?;
```

### **2. LoRA Support**

```rust
use mlmf::lora;

// Load base model + LoRA adapter in one call
let model = lora::load_model_with_adapter(
    "./base-model",
    "./lora-adapter", 
    options
)?;
```

### **3. Multimodal Models**

```rust
use mlmf::multimodal::{MultiModalLoader, Modality};

// Handle text, image, audio, video modalities
let loader = MultiModalLoader::new(config, base_options)
    .with_modality_path(Modality::Text, "./text-model")
    .with_modality_path(Modality::Image, "./vision-model");
```

### **4. Distributed Loading**

```rust
use mlmf::distributed::{DistributedLoader, ShardingStrategy};

// Multi-node model sharding and inference
let distributed_loader = DistributedLoader::new(
    DistributedConfig::new()
        .sharding_strategy(ShardingStrategy::LayerWise)
)?;
```

### **5-8. Additional Systems**

- **Dynamic Quantization**: Runtime model compression/decompression
- **Metadata Management**: Rich model provenance and quality tracking  
- **Checkpoint Management**: Advanced versioning and rollback capabilities
- **Universal API**: Unified interface across all supported formats

---

## 💡 **Quick Integration Examples**


### **Basic Model Loading (Lightbulb Use Case)**

```rust
use mlmf::{LoadOptions, loader};
use candle_core::{Device, DType};

let options = LoadOptions {
    device: Device::cuda_if_available(0).unwrap_or(Device::Cpu),
    dtype: DType::F16,
    use_mmap: true,
    progress: Some(mlmf::progress::default_progress()),
    ..Default::default()
};

let loaded_model = loader::load_safetensors("./models/llama-7b", options)?;
```

### **Architecture Detection (Cognition Use Case)**  

```rust
use mlmf::name_mapping::{TensorNameMapper, Architecture};

let tensor_names = vec![
    "model.embed_tokens.weight".to_string(),
    "model.layers.0.self_attn.q_proj.weight".to_string(),
];

let mapper = TensorNameMapper::from_tensor_names(&tensor_names)?;
assert_eq!(mapper.architecture(), Architecture::LLaMA);

// Get mapped name for your format
let mapped = mapper.map_name("model.layers.0.self_attn.q_proj.weight");
```

### **Cached Loading (Performance Critical)**

```rust
use mlmf::cached_loader::{CachedModelLoader, CacheConfig};

let cache_config = CacheConfig::new()
    .max_models(10)
    .max_memory_gb(32)
    .ttl(Duration::from_hours(2));
    
let cached_loader = CachedModelLoader::with_config(cache_config);
let model = cached_loader.load("./model", options)?;

// Subsequent loads are instant from cache
```
