We’re introducing custom instructions so that you can tailor ChatGPT to better meet your needs. This feature will be available in beta starting with the Plus plan today, expanding to all users in the coming weeks. Custom instructions allow you to add preferences or requirements that you’d like ChatGPT to consider when generating its responses.
We’ve heard your feedback about the friction of starting each ChatGPT conversation afresh. Through our conversations with users across 22 countries, we’ve deepened our understanding of the essential role steerability plays in enabling our models to effectively reflect the diverse contexts and unique needs of each person.
ChatGPT will consider your custom instructions for every conversation going forward. The model will consider the instructions every time it responds, so you won’t have to repeat your preferences or information in every conversation.
For example, a teacher crafting a lesson plan no longer has to repeat that they’re teaching 3rd grade science. A developer preferring efficient code in a language that’s not Python – they can say it once, and it’s understood. Grocery shopping for a big family becomes easier, with the model accounting for 6 servings in the grocery list.

What would be three important things to teach about the moon?
- Formation and Structure: One of the most important aspects to teach about the Moon is its formation and structure. It’s believed that the Moon was formed about 4.5 billion years ago, shortly after the formation of the Solar System. A popular theory is the Giant Impact Hypothesis, which suggests that a Mars-sized body, referred to as Theia, collided with Earth, and the debris from this collision eventually coalesced to form the Moon. In terms of structure, the Moon has a thin crust, a mantle, and a small, partly molten core, similar to Earth but much less geologically active.
- Moon Phases and Tides: Understanding the phases of the Moon is a crucial aspect of astronomy. The Moon orbits Earth about once every 27.3 days, and as it does, the angle at which sunlight hits it changes, causing the visible portion from Earth to cycle through phases: new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, and waning crescent. Additionally, the Moon’s gravitational pull affects Earth’s oceans, causing tides. The Moon, in conjunction with the Sun, causes high and low tides, an effect that has significant implications for marine life and human activities.
- The Moon and Space Exploration: The Moon plays a crucial role in human space exploration. The Apollo missions of the 1960s and 1970s marked a significant milestone in space exploration, with Apollo 11 landing the first two people on the Moon in 1969. These missions brought back lunar rocks that have greatly contributed to our understanding of the Moon and the Solar System. The Moon continues to be a focal point for future space exploration missions, as establishing a human base there could serve as a stepping stone for further exploration into the Solar System, including Mars.
What would be three important things to teach about the moon?
Teaching third-grade students about the moon involves several core concepts. Here are three key topics to consider:
- Phases of the Moon
- The Moon’s Relationship with the Earth
- Physical Features of the Moon
| Topic | Pros | Cons |
| Phases of the Moon | Helps students understand cyclical patterns and time. It’s also quite observable, offering an immediate connection to their own experiences. | It may be a slightly complex concept for some students to grasp initially, particularly the reasons behind the moon’s different phases. |
| The Moon’s Relationship with the Earth | This topic is vital for explaining concepts like gravity, tides, and how the moon orbits the earth. It can also lead to further discussions about the solar system. | Understanding the moon’s impact on Earth requires some basic understanding of physical science, which may be challenging for some third graders. |
| Physical Features of the Moon | Students usually find this interesting, particularly topics like craters and the absence of atmosphere. This can lead to discussions about space exploration. | Without proper visual aids (like high-quality images or models), this topic can be somewhat abstract for third-grade students. |
Ultimately, your choice of what to emphasize will depend on your students’ existing knowledge, the curriculum you are following, and the resources you have available.

Write me code for getting the nth number in the Fibonacci sequence
Sure, here is a simple Python function to compute the nth number in the Fibonacci sequence using a recursive method:
def fibonacci_recursive(n):
if n ≤ 0:
print("Input should be a positive integer")
return None
elif n == 1:
return 0
elif n == 2:
return 1
else:
return fibonacci_recursive(n-1) + fibonacci_recursive(n-2)
# Test
print(fibonacci_recursive(10))
This recursive solution, however, is not very efficient (it has an exponential time complexity due to repeated calculations), especially for larger values of n.
Here’s a more efficient version using dynamic programming (this has linear time complexity):
def fibonacci_dp(n):
if n ≤ 0:
print("Input should be a positive integer")
return None
elif n == 1:
return 0
elif n == 2:
return 1
fib = [0, 1]
while len(fib) < n:
fib.append(fib[-1] + fib[-2])
return fib[-1]
# Test
print(fibonacci_dp(10))
In these functions, n=1 corresponds to the first number in the Fibonacci sequence (which is 0), n=2 corresponds to the second number (which is 1), and so on.
Write me code for getting the nth number in the Fibonacci sequence
package main
import "fmt"
func Fibonacci(n int) int {
if n ≤ 1 {
return n
}
a, b := 0, 1
for i := 2; i ≤ n; i++ {
a, b = b, a+b
}
return b
}
func main() {
fmt.Println(Fibonacci(10)) // replace 10 with the nth number
}
