Download PyGPT
PyGPT is an all-in-one desktop AI assistant that provides direct interaction with OpenAI language models, including GPT-5, GPT-4, o1, and o3, through the OpenAI API. Beyond OpenAI, the application supports alternative large language models via SDKs and LlamaIndex, including models from HuggingFace, locally available models through Ollama (such as Llama 3, Mistral, DeepSeek V3/R1, and Bielik), and cloud-based models like Google Gemini, Anthropic Claude, Perplexity / Sonar, and xAI Grok. This consolidated approach allows users to access numerous AI models through a single local interface, with the user controlling which model receives each request.
The program offers multiple operation modes tailored to different tasks, including standard chat, specialized assistants, autonomous agents, raw text completions, vision analysis, and image generation. PyGPT extends beyond text-only responses through filesystem integration, enabling the AI to read files from local storage, write generated content to specified locations, and manage file transfers between conversations and the host system. A built-in code execution engine runs Python scripts for data processing, automation, and calculations, while web search capabilities through DuckDuckGo, Google, and Microsoft Bing retrieve current information from the internet. Speech recognition powered by OpenAI Whisper, Google, and Bing enables voice-driven conversations, and speech synthesis from Microsoft Azure, Google Cloud, Eleven Labs, and OpenAI Text-To-Speech converts responses into natural-sounding audio.
For flexible customization, PyGPT features a preset system for managing prompts, model parameters, and interaction templates, along with persistent context memory with save and load functionality to preserve conversation states across sessions. The plugin architecture supports custom extensions and third-party modules, while LlamaIndex integration enables document-based conversations where the assistant retrieves relevant information from user-provided files. PyGPT is a free product ($0.00 USD) available for Windows and Linux, operating as a self-contained desktop tool focused on model orchestration and local execution, with a codebase available for inspection and modification.
