Newsroom
Announcements, transparency reports, research highlights, and engineering deep-dives from across Curos. Everything is written for people, not for a press cycle.
The newsroom is where we talk about what we are building and why. If you prefer the short version, the annual report and the transparency page carry the numbers.
The case for accountable AI infrastructure
A year and a half in, the argument behind Curos — and what it will take to keep it true.
Corus is out of preview: what changed
Two weeks of public use taught us where the fair-use limits were wrong. We fixed them, and published the evaluation report.
Introducing Corus, our frontier model
Our most capable model is now available to every Ichnus user, free of charge.
A field guide to our evaluation suite
A practical how-to for reading our evaluation reports and benchmark tables — what the numbers mean and where they come from.
How Curos is funded
A plain-language look at where our funding comes from — and where it doesn't.
Scaling interpretability: our roadmap
How the interpretability team's findings feed into release decisions — and where we are taking the work next.
Curos's approach to model evaluations
How we test Ichnus for safety and capability before every release — the four layers, the release gates, and the published reports.
Mantus 3 is here
The default Ichnus model gets a new version — and the release notes are in plain language.
Our 2025 annual report
The audited numbers for Curos's first full year: $8.4M raised, where it came from, and where it went.
Mantus 2 improves long-context reasoning
The reasoning team's work on compositional reasoning under distraction shaped Mantus 2 — here is what changed.
Krus 2 and a faster Ichnus
A deep dive into what makes Krus 2 cheaper and faster to run — and why that is the whole point.
How we keep Ichnus free
Free is not the absence of cost — it is a decision about who pays. Here is the economics behind Ichnus.
A look inside Ichnus's safety evals
How the evaluation suite works, what it catches, what it does not, and why a release can be delayed by a committee.
Meet Krus, our fast everyday model
The smallest model in the Ichnus family does the most work. Here is why a fast tier matters for free access.
Our first transparency report
Six weeks after launch, the numbers: where Ichnus's funding comes from, what we spent it on, and what we refuse to take.
Introducing Ichnus: a free assistant from a non-profit
Ichnus is live — a free AI assistant powered by three model tiers, built by a non-profit with no ads and no data sales.
Why Curos chose to be a non-profit
The argument that AI is becoming infrastructure, and infrastructure should answer to the public — not to a quarterly earnings call.
Curos is coming out of stealth
A group of researchers and engineers spent a year asking whether AI could be built as a public good. Today we can tell you what came of it.
