“What: Starting today, you can try out Bard with Gemini Pro for text-based prompts in the UK. We’ve specifically tuned Gemini Pro in Bard to be far more capable at things like understanding and summarising, reasoning, coding, and planning.”
“Why: Earlier this month, Google introduced Gemini, the most capable AI model in the world. Gemini unlocks new ways to create, interact and collaborate with Bard. We are working hard to make this broadly available, expanding to the UK in English today and more countries and languages over time.”
I’ve done some preliminary tests of Bard, now that it’s been updated with Gemini Pro, and my initial thoughts are that it’s much better than PaLM 2 (not surprising), but probably on par with GPT-4 (disappointing). Your mileage may vary, depending on what you’re using it for.
