Response to same query from ChatGPT 3.5 legacy: "Halley's Comet is a periodic comet that appears in our sky approximately once every 76 years. It was last visible from Earth in 1986 and is expected to return in 2061. In the 15th century, Halley's Comet appeared in the year 1456. In the 16th century, it appeared in the year 1531 and again in 1532." And ChatGPT 3.5 default: "Halley's Comet, also known as Comet Halley, made several appearances in the 15th and 16th centuries. In the 15th century, the comet was recorded as having appeared in 1456 and 1470. The appearance in 1456 was particularly notable as it occurred shortly before the fall of Constantinople to the Ottoman Empire, and was seen as a bad omen by many. In the 16th century, Halley's Comet was recorded as having appeared in 1531, 1607, and 1618. The appearance in 1607 was particularly well-documented, with the astronomer Johannes Kepler making detailed observations of the comet's motion." It would seem that the ChatGPT plugins is rather unpredictably less reliable than other versions.
