What is Clusy
Clusy is an agent-native notebook platform for machine learning and data science. You describe the outcome you want in plain language, and the Clusy agent plans the work, writes and runs notebook cells on cloud CPUs or GPUs, and returns results you can inspect, edit, and re-run. Every step stays visible in a real notebook, so you keep full code-level control.
How to use Clusy
- Describe your goal – Write a natural language prompt describing the outcome you want (e.g., "LoRA fine-tune a model").
- Agent plans and executes – The Clusy agent sources and inspects data, selects architecture and compute, writes and runs notebook cells on cloud sandboxes.
- Inspect and iterate – Review the generated notebook, edit cells, re-run steps, or fork the notebook to branch experiments.
- Queue follow-ups – While a notebook is executing, you can queue additional prompts to run in parallel.
Features of Clusy
- Agent-native notebook – An AI agent writes and runs code in a real notebook; you retain full code-level control.
- Cloud compute – Managed sandboxes with CPUs and GPUs (T4, L4, A10, L40S, A100, H100, H200) up to 141 GB VRAM.
- Experiment branching – Fork notebooks to compare different approaches side by side.
- Data connectivity – Upload files, pull public datasets (e.g., Hugging Face), or connect to Databricks and Snowflake warehouses.
- Multiple AI models – Choose from Auto, DeepSeek, Kimi, Anthropic Claude, OpenAI GPT depending on plan.
- End-to-end workflows – From dataset discovery and preprocessing to model training, evaluation, and fine-tuning.
Use Cases of Clusy
- LLM fine-tuning – Fine-tune models like LoRA with a single prompt, including dataset discovery, preprocessing, sandboxed training, and parallel experiments.
- Reproducing research – Reproduce models from papers by fetching public datasets and running experiments.
- Post-training models – Post-train open-weight models for custom systems (e.g., coding agents).
- Idea validation and market research – Use Clusy to analyze data and generate insights.
- Data science workflows – Build, branch, run, and evaluate ML and data science pipelines entirely in the cloud.

FAQ
What is Clusy? Clusy is an agent-native notebook platform for machine learning and data science. You describe the outcome you want in plain language, and the Clusy agent plans the work, writes and runs notebook cells on cloud CPUs or GPUs, and returns results you can inspect, edit, and re-run. Every step stays visible in a real notebook, so you keep full code-level control.
How is Clusy different from Jupyter or Google Colab? Traditional notebooks give you an empty editor; Clusy gives you an agent that does the work in the notebook with you. It sources and inspects data, selects architecture and compute, executes end-to-end, and supports branching so you can fork a notebook and compare experiments side by side. The output is still a real notebook you can read, edit, and share.
Which AI models can I use in Clusy? The Free plan includes the Auto model for fast, low-cost everyday work. Plus adds open models such as DeepSeek and Kimi. Pro and Max unlock every model, including Anthropic Claude (Sonnet and Opus) and OpenAI GPT.
What GPUs and compute does Clusy provide? Every plan runs on managed cloud sandboxes. Free starts with an 8 vCPU / 8 GB RAM CPU sandbox. Plus adds entry GPUs (T4, L4, A10) up to 24 GB VRAM, Pro adds mid-tier GPUs (L40S, A100) up to 80 GB VRAM, and Max unlocks top-end H100 and H200 GPUs up to 141 GB VRAM with up to 128 GB sandbox RAM.
Can Clusy connect to my own data? Yes. You can upload files, pull public datasets from sources like Hugging Face, or connect directly to your Databricks or Snowflake warehouse and work against live tables from the notebook.
Is there a free plan? Yes. Clusy is free to start — the Free plan includes the Auto model on a CPU sandbox with no credit card required. Paid plans start at $30/month (Plus), with Pro at $90/month and Max at $200/month, all with usage-based allowances and optional pay-as-you-go.
