PaLM 2

Compute-optimal training: Trained compute-optimally on a larger, higher-quality, more multilingual corpus than PaLM 1.

Multilingual strength: Major improvement in 100+ languages; supports translation, generation, and reasoning across a much broader language set.

Reasoning competitive with GPT-4: Particularly strong on mathematical reasoning, approaching GPT-4 on several benchmarks.

Flan-PaLM 2: The instruction-tuned version performs well on MMLU, BIG-bench Hard, and code generation - powering Google's consumer AI products.
