+- **gpt4all-backend**: The GPT4All backend maintains and exposes a universal, performance optimized C API for running inference with multi-billion parameter Transformer Decoders.
 This C API is then bound to any higher level programming language such as C++, Python, Go, etc.
 - **gpt4all-bindings**: GPT4All bindings contain a variety of high-level programming languages that implement the C API. Each directory is a bound programming language. The [CLI](gpt4all_cli.md) is included here, as well.
 - **gpt4all-api**: The GPT4All API (under initial development) exposes REST API endpoints for gathering completions and embeddings from large language models.

 GPT4All models are artifacts produced through a process known as neural network quantization.

 It is not advised to prompt local LLMs with large chunks of context as their inference speed will heavily degrade.
 You will likely want to run GPT4All models on GPU if you would like to utilize context windows larger than 750 tokens. Native GPU support for GPT4All models is planned.
 
-**Inference Performance**
+**Inference Performance:**
 Which model is best? That question depends on your use-case. The ability of an LLM to faithfully follow instructions is conditioned
 on the quantity and diversity of the pre-training data it trained on and the diversity, quality and factuality of the data the LLM
 was fine-tuned on. A goal of GPT4All is to bring the most powerful local assistant model to your desktop and Nomic AI is actively
