With Plexe, you can build complex models by describing them in natural language, eliminating the need for extensive manual coding. It leverages an intelligent multi-agent architecture to automate the entire model development lifecycle, from intent definition to deployment.\n\nWhether you're predicting sentiment, housing prices, or customer churn, Plexe transforms your description into a fully functional ML model, making AI development more accessible and efficient.\n\n## Installation\n\nGetting started with Plexe is straightforward. You can install it via pip:\n\nbash\npip install plexe                  # Standard installation, minimal dependencies\npip install plexe[transformers]    # Support for transformers, tokenizers, etc.\npip install plexe[chatui]          # Local chat UI for model interaction\npip install plexe[all]             # All optional dependencies\n\n\nPlexe integrates with various LLM providers. Ensure you set your preferred provider's API key as an environment variable:\n\nbash\nexport OPENAI_API_KEY=<your-key>\nexport ANTHROPIC_API_KEY=<your-key>\nexport GEMINI_API_KEY=<your-key>\n\n\nFor a comprehensive list of providers and their environment variables, refer to the [LiteLLM documentation](https://docs.litellm.ai/docs/providers){target=\"_blank\"}.\n\n## Examples\n\nDefining and using a model with Plexe is intuitive:\n\npython\nimport plexe\n\n# 1. Define the model using natural language and schemas\nmodel = plexe.Model(\n    intent=\"Predict sentiment from news articles\",\n    input_schema={\"headline\": str, \"content\": str},\n    output_schema={\"sentiment\": str}\n)\n\n# 2. Build and train the model\nmodel.build(\n    datasets=[your_dataset],\n    provider=\"openai/gpt-4o-mini\",\n    max_iterations=10\n)\n\n# 3. Use the model to make predictions\nprediction = model.predict({\n    \"headline\": \"New breakthrough in renewable energy\",\n    \"content\": \"Scientists announced a major advancement...\"\n})\n\nprint(f\"Sentiment prediction: {prediction['sentiment']}\")\n\n# 4. Save and load the model\nplexe.save_model(model, \"sentiment-model\")\nloaded_model = plexe.load_model(\"sentiment-model.tar.gz\")\n\n\nYou can also define models with more complex intents, and Plexe will infer the schema if not provided:\n\npython\nmodel = plexe.Model(\n    intent=\"Predict housing prices based on features like size, location, number of bedrooms, etc.\"\n)\n# Schema can be automatically inferred during build if not explicitly provided\nmodel.build(provider=\"openai/gpt-4o-mini\")\n\n\n## Why Use Plexe?\n\nPlexe offers a suite of powerful features that make it an indispensable tool for ML development:\n\n*   **Natural Language Model Definition**: Describe your models in plain English, and Plexe handles the implementation complexity.\n*   **Multi-Agent Architecture**: A system of specialized AI agents analyzes requirements, plans solutions, generates code, tests and evaluates, and packages the model for deployment.\n*   **Automated Model Building**: Build complete models with a single method call, significantly accelerating the experimentation and development process.\n*   **Distributed Training with Ray**: Leverage Ray for distributed model training and evaluation, enabling faster parallel processing and efficient exploration of model variants.\n*   **Data Generation & Schema Inference**: Generate synthetic data or let Plexe automatically infer input and output schemas based on your intent.\n*   **Multi-Provider Support**: Use your preferred LLM provider, including OpenAI, Anthropic, Ollama, and Hugging Face, with seamless integration via LiteLLM.\n\n## Links\n\n*   **GitHub Repository**: [plexe-ai/plexe](https://github.com/plexe-ai/plexe){target=\"_blank\"}\n*   **Official Documentation**: [docs.plexe.ai](https://docs.plexe.ai){target=\"_blank\"}\n*   **Discord Community**: [Join our Discord](https://discord.gg/SefZDepGMv){target=\"_blank\"}\n*   **YouTube Demo**: [Watch the demo on YouTube](https://www.youtube.com/watch?v=bUwCSglhcXY){target=\"_blank\"}","metrics":{"detailViews":1,"githubClicks":1},"dates":{"published":null,"modified":"2025-10-13T23:01:52.000Z"}}
