## What it is
Entropix is a research project implementing entropy-based sampling and parallel chain-of-thought decoding for large language models, aiming to improve output quality via inference-time compute. It includes an inference stack and sampler, with planned splits into a local single-GPU/Apple Silicon version and a multi-GPU/TPU large-model version.

## Use cases
- improve llm output quality with entropy-aware sampling
- simulate o1-style chain of thought reasoning at inference time
- experiment with parallel cot decoding
- research adaptive sampling strategies for transformers
- run reasoning experiments on local gpus or apple silicon
- serve large models across multiple h100s or tpus

## When to choose
- you are an ml researcher exploring sampling and decoding techniques
- you want to experiment with entropy-based inference-time compute on small models
- you need a testbed for prototyping sampler ideas in jax, pytorch, or mlx

## When to avoid
- you need a stable production inference server today
- you want a turnkey chat product with support and guarantees
- you cannot tolerate frequent breaking changes in a research codebase
