How is "BERT" pronounced?
BERT (Bidirectional Encoder Representations from Transformers) is pronounced "burt" /bɜːrt/ — one syllable, exactly like the name Bert. The vowel is /ɜː/ (like "bird" or "herb"). It is treated as a single word, not spelled out as letters. Google researchers introduced this pronunciation alongside the paper. In a sentence: "Fine-tuning BERT on a domain-specific corpus improved our NER accuracy by 12 percentage points."
2 / 5
How is "CLIP" pronounced?
CLIP (Contrastive Language–Image Pre-training) is pronounced "klip" /klɪp/ — a single syllable, rhyming with "tip" or "ship." The vowel is short /ɪ/. It is said as a word, not spelled out letter-by-letter. The consonant cluster kl- is the same as in "climb." In a sentence: "We used CLIP embeddings to build a semantic image search engine without labelled training data."
3 / 5
How is "RLHF" pronounced?
RLHF (Reinforcement Learning from Human Feedback) is pronounced "AR-EL-AITCH-EF" /ɑːr ɛl eɪtʃ ɛf/ — each of the four letters spelled out individually. Unlike BERT or CLIP, RLHF is not typically blended into a word. It is a relatively newer term so the letter-by-letter style has stuck. Equal stress across all letters. In a sentence: "RLHF was a key alignment technique used in training the early versions of ChatGPT."
4 / 5
How is "RAG" pronounced?
RAG (Retrieval-Augmented Generation) is pronounced "rag" /ræɡ/ — one syllable, rhyming with "bag" or "flag." The vowel is short /æ/. It is spoken as a word, not as individual letters, in the AI community. In a sentence: "We implemented a RAG pipeline so the chatbot can answer questions about proprietary documents not in its training data."

How is "GPT" pronounced?
GPT (Generative Pre-trained Transformer) is pronounced "JEE-PEE-TEE" /dʒiː piː tiː/ — three letter names spoken individually with even stress. The G is the letter name /dʒiː/ ("gee"), not a hard consonant. It is always spelled out; never blended into a word. In a sentence: "The application calls the GPT-4o API endpoint to generate personalised product descriptions."
