## Decision facts: gpt4all

- **Adopt for:** GPT4All is an open-source project designed to facilitate the local deployment of large language models (LLMs). It supports commercial usage with a permissive MIT license and is implemented in C++.

## Choose when

### Choose shimmy if…

- shimmy is primarily Rust; gpt4all is C++.
- License: shimmy is Apache-2.0, gpt4all is MIT.
- Tags unique to shimmy: api-server, command-line-tool, developer-tools, gguf.
- Also covers Model Training.

### Choose gpt4all if…

- gpt4all is primarily C++; shimmy is Rust.
- License: gpt4all is MIT, shimmy is Apache-2.0.
- Tags unique to gpt4all: ai-chat, llm-inference.
- - When you require on-device inference capabilities without reliance on cloud services.

## When NOT to use shimmy

- Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.

## When NOT to use gpt4all

- - In environments strictly requiring models supported by mainstream frameworks like TensorFlow or PyTorch, as GPT4All focuses on its standalone implementation.
- - When the project demands seamless integration with popular cloud infrastructures that don't align well with local deployments.
