Two new benchmarks, MTEB-PT and MTEB-PT (Brazilian Portuguese), have been released to evaluate text embedding models specifically for the Portuguese language. These benchmarks address the underrepresentation of Portuguese in existing evaluations, which often rely on translated datasets or multilingual averages. The new benchmarks comprise numerous native Portuguese tasks across various categories, including semantic textual similarity, classification, retrieval, and reranking. Initial evaluations show that model performance is highly task-dependent, and rankings on multilingual benchmarks do not reliably predict Portuguese-specific performance, highlighting the need for language-native evaluations.

IMPACT These benchmarks will enable more accurate evaluation of language models for Portuguese, leading to better model selection and development for this language.
