CAJAL

What is CAJAL?

CAJAL is an open-source project for writing scientific papers on your own computer instead of through a hosted chatbot. The GitHub page describes a Qwen 27B model fine-tuned for academic writing that can run offline on a single RTX 3090 graphics card, and the project connects to any Ollama-compatible local model. It drafts papers in the usual academic layout, looks up references through arXiv and CrossRef, and passes each draft to a panel of AI judges it calls a tribunal, which gives a quick peer-review style score. The repository also mentions a CognitionBoard and a token-compression feature, plus kits for agent frameworks and editors such as VS Code and Jupyter. Researchers and graduate students use it to get a first draft or a rough review without sending unpublished work to a cloud service. The code is free to use, so the real cost is the hardware and the time spent checking the output.

Use cases

• Draft a structured research paper
• Pull references from arXiv and CrossRef
• Score a draft with AI reviewers
• Write academic text offline
• Add paper writing to agent workflows

Who it's for

• Researchers
• Graduate students
• Python developers
• Open-source users

Why use CAJAL

• Keeps prompts and unpublished research on your own machine rather than a third-party API.
• No subscription or per-token bill, since the model runs on hardware you control.
• The judge panel gives a first-pass critique before you ask a colleague to read the draft.
• Framework and editor kits let you call paper generation from tools you already use.

How to get started with CAJAL

1. Install a local model runtime such as Ollama and download a compatible model.
2. Clone the CAJAL repository from GitHub and follow its setup steps.
3. Give it a research topic and let it draft the paper section by section.
4. Read the judge scores and the references it found, then edit and verify the draft yourself.

CAJAL limitations

• Self-hosted: you supply the GPU and the local model
• The large fine-tuned model targets a high-end consumer GPU such as an RTX 3090
• Generated papers need careful human checking of claims and citations
