Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://lastmile-ai.gitbook.io/lastmile-ai-docs/models/intro-to-models.md). # 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** We currently support the following models: * 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 * 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 ## **Custom Models** 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
