The PaLM and PaLM 2 Models:
PaLM Model:
- Developed by Google in April 2022.
- The largest language model to date with 540 billion parameters.
- Trained on a vast multilingual dataset with over 780 billion tokens from more than 100 languages, with over 75% in English.
- Capable of performing tasks such as question answering, language understanding, and arithmetic.
- Achieved the best performance on standard benchmarks for natural language understanding and natural language generation.
PaLM 2 Model:
- Released by Google in May 2023.
- No specific information about model size or training data disclosed.
- Trained on more than 100 languages, with enhanced capabilities in understanding and generating complex text.
- Surpassed advanced English proficiency exams at the mastery level.
- Trained on a large quantity of publicly available programming code, improving reasoning and logical thinking abilities compared to the original PaLM model.
- Can run on mobile devices, expanding Google’s capabilities in products like Gmail and Google Docs.
