Efficiency Comparability Abstract

GPT-4.5 vs GPT-4o: API Comparability

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

With GPT-4.5, the enter and output token value are respectively 30 and 15 instances costlier in comparison with GPT 4o!

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

Immediate: “A make-up firm is dropping its clients to its rivals resulting from lack of product selection. They don’t have the assets but to scale up and add extra merchandise, plan a method for them utilizing which they’ll leverage their current merchandise to retain their clients.”

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 most suitable choice for brand spanking 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.selections[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 value
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.selections[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 Value: ${total_cost:.6f}")

# Show end result
from IPython.show import Markdown
show(Markdown(completion.selections[0].message.content material))

Is GPT-4.5 Well worth the Worth?

Each GPT-4.5 and GPT-4o are for on a regular basis duties like content material creation – which for many of us means – writing or proofreading our emails, or creating some form of social media put up. We can also use these fashions for summarizing lengthy stories or pdfs or making fast flowcharts or understanding some new ideas.

For such duties, that though make our lives less complicated, it typically doesn’t justify to pay 15 instances greater than what we’re at the moment paying! So the conundrum rises: when to make use of GPT-4.5 and when to make use of GPT-4.0?

Thus, use GPT-4o for on a regular basis duties the place velocity and price matter, and GPT-4.5 for high-accuracy, advanced, or mission-critical duties.

Conclusion

This GPT-4.5 vs GPT-4o comparability highlighted the strengths and trade-offs of each the fashions. Whereas GPT-4.5 excels in information accuracy and emotional intelligence, GPT-4o stands out for cost-efficiency, and multimodal capabilities. Therefore GPT-4.5 appears to be a better option for duties the place precision and reasoning are crucial – comparable to in authorized, monetary, or high-stakes analysis. Alternatively, GPT-4o is finest suited to duties enhancing productiveness and cost-efficient AI functions.

That being mentioned, essentially the most important differentiating issue is pricing. GPT-4.5 is over 15 instances costlier than GPT-4o for comparable duties, which makes it much less viable for informal customers and companies targeted on cost-effective AI integration.
