# Intro to Models

The **Models page** contains all the generative AI models available through LastMile AI. These include both standard models and custom models.

## **Standard Models**&#x20;

We currently support the following models:&#x20;

* GPT-3.5-Turbo (ChatGPT) - A large language model (LLM) by OpenAI that is capable of generating human-like responses based on given prompts.
* GPT-4 - Similar to ChatGPT, an LLM that is capable of generating human-like responses based on given prompts. GPT4 generally has higher quality responses on more complex tasks at the expense of slower speed.
* Bark - A speech synthesis model (TTS) developed by SunoAI that generates realistic sounding voices from text.
* Whisper - An automatic speech recognition system developed by OpenAI that transcribes audio into text
* PaLm - An LLM developed by Google for language tasks such as classification, summarization, and entity extraction.
* PaLm Chat - An LLM by Google that is fine tuned for multi-turn chat&#x20;
* DALL-E 2 - An image generation model developed by OpenAI that creates unique images from textual descriptions
* Stable Diffusion v1.5 - An image generation (diffusion) model that can generate high quality images in a stable manner if provided with a seed&#x20;

## **Custom Models**&#x20;

Custom models are models that you created on LastMile AI by adding your own data to a supported model. All custom models are only accessible to the user who creates it. Custom models can be configured inside workbooks to use any of the following chatGPT models:

* GPT 3.5 Turbo
* GPT 3.5 Turbo 16k
* GPT 4
