About Ren AI
Building software engineering intelligence.
Ren AI is the company. Astra is the model. Ren Code is the product. We are building AI that understands software systems as a whole — and improving it in the open.
What we are building.
Ren AI is an AI research company. Our core work is Astra — our flagship language model, built for reasoning, software engineering, long-context understanding, and agentic workflows. Astra is the intelligence layer powering every Ren AI product.
Ren Code is the first product powered by Astra: AI software engineering that reads your codebase before it changes a line of it. You describe a change. Ren Code produces a pull request you review. You stay in control of what merges.
How we work.
We publish progress honestly. Capability numbers arrive only with the evaluation harness that produces them. Negative results enter the record. The roadmap is real.
The goal is a research organization that compounds: own data, own adapters, own evaluation, own pretraining — built with the discipline installed from day one.
Intelligence through reasoning
We build systems that understand software, not systems that guess at it. Astra is designed to read a codebase as a whole and reason about changes the way an engineer would.
Honest about the stage
Ren AI is in active development. We publish progress as it is, not as we wish it were. The roadmap is real, the work is ongoing, and we say so.
Review, not automation
Every change Ren Code produces is a pull request you read. We build for human review, not blind automation. Your judgment is part of the design.
Compounding from day one
We are building Ren AI to grow: own model, own evaluation, own data discipline — installed from the start rather than retrofitted.
