A product post tells you what shipped and who can use it. A system card tells you how the lab says it behaves under abuse and where it refuses. A paper or technical report tells you the method, the data, and the comparison. Carbon-A has a blog post, a Hub model, and a technical report. Odyssey-3, so far, is a lab post and a preview. Those are different evidence grades.
We do not treat an internal evaluation as a public leaderboard. OpenAI’s speed and quality figures for GPT-6 are labeled as internal. They can still be the right numbers to quote, with that label attached.
