Since the advent of mainstream conversational AI with ChatGPT, Google has been eager for a slice of the action. Well, Bard is here now, and continues growing exponentially. Like its OpenAI-led rival, Bard has produced laughable responses to basic arithmetic and logical reasoning questions. However, Google has been developing another language model separately, which has now been fused with Bard to help with logic capabilities and even pave the way for autonomous code generation in the future.

If you aren’t familiar, Bard is based on Google’s Language Model for Dialogue Application (LaMDA), and as the name suggests, it is better at holding conversation than being your pocket logician. In 2021, Google announced its long-term vision for a new Pathways model, and in 2022, introduced the Pathways Language Model (PaLM). At the time, PaLM was a 540-billion-parameter language model trained using Pathways. Now, Google is fusing PaLM with Bard (via 9to5Google).

PaLM’s logical capabilities include arithmetic, code completion, semantic parsing, summarization, logical inference, common-sense reasoning, pattern recognition, translation, an understanding of physics, and even joke explanation. Here are a few examples Google shared last year, demonstrating these capabilities Bard lacked until recently:
