Efficiency Comparability Abstract

GPT-4.5 vs GPT-4o: API Comparability

Within the final part, now we have seen the efficiency of GPT-4.5 vs GPT-4o for numerous duties on their internet interface. Now let’s talk about their APIs. GPT-4o API has been in use for the final two years, proving to be price environment friendly whereas offering good efficiency.

With GPT-4.5, the enter and output token price are respectively 30 and 15 occasions dearer in comparison with GPT 4o!

How a lot of an influence does this imply on our pockets? To determine that out, we’ll first immediate GPT-4o API to assist me with a activity. Primarily based on the tokens consumed, we are going to estimate the value it would incur to make use of each the fashions, assuming they each give the identical consequence (or related efficiency).

Immediate: “A make-up firm is dropping its prospects to its rivals attributable to lack of product selection. They don’t have the sources but to scale up and add extra merchandise, plan a technique for them utilizing which they will leverage their present merchandise to retain their prospects.”

Enter Code:

from openai import OpenAI
import time
import tiktoken
from IPython.show import show, Markdown
with open("path_to_api_key") as file:
api_key = file.learn().strip()

task1_start_time = time.time()

shopper = OpenAI(api_key=api_key)

messages = [
{
"role": "system",
"content": """You are an expert an useful assistant"""
},
{
"role": "user",
"content": """A makeup company is losing its customers to its competitors due to lack of product variety.
They do not have the resources yet to scale up and add more products, plan a strategy for them using which they can leverage their existing products to retain their customers.
"""
}
]

# Use a suitable encoding (cl100k_base is the best choice for brand new OpenAI fashions)
encoding = tiktoken.get_encoding("cl100k_base")

# Calculate token counts
input_tokens = sum(len(encoding.encode(msg["content"])) for msg in messages)

completion = shopper.chat.completions.create(
mannequin="gpt-4o",
messages=messages
)

output_tokens = len(encoding.encode(completion.decisions[0].message.content material))

task1_end_time = time.time()


input_cost_per_1m = 2.5 # Instance: $2.5 per 1M enter tokens
output_cost_per_1m = 10 # Instance: $10 per 1M output tokens

# Calculate price
input_cost = (input_tokens / 1000000) * input_cost_per_1m
output_cost = (output_tokens / 1000000) * output_cost_per_1m
total_cost = input_cost + output_cost


# Print outcomes
print(completion.decisions[0].message)
print("----------------=Complete Time Taken for activity 1:----------------- ", task1_end_time - task1_start_time)
print(f"Enter Tokens: {input_tokens}, Output Tokens: {output_tokens}")
print(f"Estimated Price: ${total_cost:.6f}")

# Show consequence
from IPython.show import Markdown
show(Markdown(completion.decisions[0].message.content material))
