Where the larger specialist starts.

Born2-35B-A3B-Review builds on Qwen3.6-35B-A3B. These are the upstream checkpoint’s published scores, the floor our review post-training starts from. Born2’s own results will come with their methodology.

Where is the API served from?

Europe. Inference is managed by Critique.sh, part of Leemer Group, in Europe.

When will Born2-9B-Gaeilge and Born2-35B-A3B-Review arrive?

Both are in post-training at Leemer Labs. They will join the API when their evaluations are ready to publish, and platform accounts will hear first.

Can I run the models myself?

Open weights are planned for the Born2 models, with a model card and evaluation methods. The API preview comes first.

Born2-9B results, prices and throughput targets are reported by Leemer Labs and are preliminary. External scores are developer-reported and use different harnesses. Prices are set in euros as of October 2026; pounds and dollars are shown at reference rates. Prices may change before general availability.
