Together Open Data ScientistOpen-source ReAct agent that runs Python to explore data, build models, and generate analysis reports

Together Open Data Scientist is an open-source, AI-powered data analysis agent released by Together AI on GitHub. It follows the ReAct (Reasoning + Acting) framework, alternating between language-model reasoning steps and concrete Python code execution to carry out end-to-end data science tasks such as exploring datasets, computing summary statistics, building models, and producing detailed written analysis reports. The agent can execute Python in one of two modes. The "internal" mode runs code locally inside a Docker container, which is suited to single-user local development, while the "tci" mode offloads execution to Together Code Interpreter (TCI), a cloud sandbox accessed through the Together AI API. Users can upload a data directory for automatic ingestion, set a maximum number of reasoning iterations, and pick which underlying model drives the agent — DeepSeek-V3 is the default, but Llama models and others available through Together's platform can be specified. It is distributed as a pip-installable package (open-data-scientist) and exposes both a command-line interface and a Python API. The CLI supports options such as --write-report to generate a Markdown analysis report, --save-trace to log the full query and execution trace, and session reuse via session IDs. The Python API centers on a ReActDataScienceAgent class that takes a natural-language task and returns results. The project is explicitly labeled experimental software. Because all code and analysis are AI-generated, outputs may contain errors or suboptimal approaches and are best treated as a starting point for exploration and learning rather than production decision-making. The maintainers stress that human oversight and validation are required, especially for critical business or research applications. Compared with commercial AI data-analysis assistants like ChatGPT's Advanced Data Analysis or notebook copilots, Together Open Data Scientist is differentiated by being fully open source, self-hostable, model-agnostic within Together's ecosystem, and capable of autonomously chaining many code-execution steps toward a complete report rather than a single one-shot answer.
