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 varied 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 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 value it is going to incur to make use of each the fashions, assuming they each give the identical end result (or related efficiency).

Immediate: “A make-up firm is shedding its prospects to its rivals on account of 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()

consumer = 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 appropriate 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 = consumer.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 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.selections[0].message)
print("----------------=Whole 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)) 

Output:

API Value Evaluation

This implies, GPT-4.5 is roughly 15.4 occasions costlier than GPT-4o for a similar immediate! However is it price paying the value?

Is GPT-4.5 Definitely worth the Value?

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 type of social media put up. We may use these fashions for summarizing lengthy experiences or pdfs or making fast flowcharts or understanding some new ideas.

For such duties, that though make our lives easier, it usually doesn’t justify to pay 15 occasions greater than what we’re at present 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 pace and price matter, and GPT-4.5 for high-accuracy, advanced, or mission-critical duties.

Even OpenAI acknowledges that GPT-4.5 is pricey and never a substitute for GPT 4o. This official e mail from OpenAI additionally means that they could disable it in API to prioritise different developments.

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 data accuracy and emotional intelligence, GPT-4o stands out for cost-efficiency, and multimodal capabilities. Therefore GPT-4.5 appears to be a more sensible choice for duties the place precision and reasoning are crucial – similar to in authorized, monetary, or high-stakes analysis. However, GPT-4o is finest suited to duties enhancing productiveness and cost-efficient AI functions.

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

Finally, the selection between the 2 is determined by your wants, funds, and the complexity of your AI-powered workflows. If affordability and flexibility matter extra, GPT-4o is the best way to go.
