| Summary | ||
| Verdict | EU-ready OpenAI's first major open-weights release. Apache 2.0, MoE with 5.1B active over 117B total, MXFP4 quantised to fit a single 80GB GPU. Historic shift for a vendor that built its brand on closed weights. | EU-ready Fully open small model: Apache 2.0 weights, training data published, engineering blueprint public. 6 native languages (EN/FR/ES/DE/IT/PT) covers major EU markets. 128K context via YARN. Strong default for edge or on-prem EU deployments where transparency matters. |
