What are ExLlamaV2 and Guidance?
ExLlamaV2
ExLlamaV2 is an inference library optimized for running quantized large language models efficiently on modern consumer GPUs. Its EXL2 quantization format allows flexible bitrates for the best speed-quality balance.
- EXL2 flexible quantization
- Fast single-GPU inference
- Low memory footprint
- Built-in server
Guidance
Guidance is a programming paradigm from Microsoft for steering language model output with interleaved generation, control flow, and constraints. It can run against locally hosted models to produce reliable structured results.
- Interleaved generation control
- Token healing
- Regex and grammar constraints
- Works with local models
