Can you expand on what's "very limited" about the Bard version here? They look roughly equivalent, slightly less flowery language, different format (day planning rather than rough), similar level of detail. Unless the facts about Japan are just wrong, which I don't have the expertise to judge, it seems about the same?
The logical reasoning in Bard is off in this example (as its basically just putting each destination together with a list of attractions in each city). Additional prompting to tell it to correct the output doesn't seem to have the same effect as it does in the OpenAI models.
Arguably there's an issue in the Bard one in that it splits the Tokyo portion in two and has you return there to fly home, but also some people might prefer this to have a round-trip ticket to the same airport.
Maybe it's my lack of knowledge about Japan, but I'm just not seeing a difference between the two in terms of logical reasoning.
