Introduction
AI models have revolutionized industries, enabling businesses to automate tasks, generate insights, and optimize workflows. However, as usage grows, so does the need for cost-efficient solutions. Choosing the right AI model isn’t just about performance—it’s also about affordability.
In this blog, we compare Amazon Nova Pro-v1.0 and OpenAI GPT-4o, two powerful models with different pricing structures, by evaluating their cost-effectiveness in a real-world summarization task.
Amazon Nova Pro-v1.0 is a cutting-edge AI model capable of processing and generating text, images, and videos, offering versatile applications across various industries. Recently unveiled at Amazon's re:Invent conference, it provides a cost-efficient solution for businesses seeking advanced GenAI capabilities.
Pricing Models
Before comparing, it’s crucial to understand how these models are priced. Both charge based on the number of tokens used:
- Input Tokens: The text provided to the model for processing.
- Output Tokens: The text generated by the model in response.
Here’s the on-demand pricing for each model:
| Model | Input Tokens ($/1M) | Output Tokens ($/1M) |
|---|---|---|
| OpenAI GPT-4o | $2.5 | $10.0 |
| Amazon Nova Pro-v1.0 | $0.8 | $3.2 |
These costs may seem negligible for small tasks, but they quickly add up when scaling operations. Thus, understanding token usage is key to managing costs effectively.
Summarization Task
To compare costs, we conducted a summarization task where both models were given the same input text—a narrative about an old clockmaker and his apprentice. The goal was to generate a concise summary of the story while analyzing the token usage and associated costs.

The Clockmaker’s Apprentice
(In the quaint town of Willowshade, nestled between rolling hills and meandering streams, there lived an old clockmaker named Elias. His shop, filled with the soft ticking of countless clocks, was a sanctuary of time. Each clock was a masterpiece, intricately designed with brass gears, golden hands, and polished wood. But Elias was growing old, and his hands, once steady as the earth’s rotation, had begun to tremble.
One frosty morning, a young boy named Finn appeared at the shop’s door. His clothes were tattered, his cheeks flushed with cold, but his eyes sparkled with curiosity.
“Sir, I want to learn to fix time,” Finn declared, clutching a broken pocket watch. Elias chuckled at the boy’s earnestness.
“You can’t fix time, lad,” Elias said. “But you can mend the tools that keep it.”
Finn became Elias’s apprentice. Day by day, he learned the art of clockmaking. He polished gears, measured springs, and practiced the delicate dance of assembling a clock. His favorite was a grand pendulum clock that stood in the corner of the shop, its deep chime echoing through the room every hour.
One evening, as the sun dipped below the horizon, Elias took Finn to the attic. There, covered in a layer of dust, lay a peculiar clock. Its face was blank, and its hands moved erratically, spinning forward, then backward.
“This,” Elias whispered, “is the Clock of Lost Moments. It doesn’t measure hours or minutes. It measures moments forgotten, regrets, or times we wish we could relive.”
Finn stared in awe. “Can it bring back moments?”
Elias shook his head. “No. It’s a reminder, boy. Time moves only forward. We can’t reclaim it, but we can choose to make the most of the moments we’re given.”
Over the years, Finn became a master clockmaker. When Elias passed, Finn inherited the shop. He restored the Clock of Lost Moments and placed it in the shop window, where its mysterious movements fascinated passersby. People began to visit, not just to buy clocks, but to share their stories of moments they cherished or wished to forget.
And so, the little clock shop became more than a place to mend timepieces—it became a place to mend hearts.)
Both models produced summaries of similar quality, but their token usage and costs varied significantly. Let’s examine this in detail.

Summary:
In the charming town of Willowshade, an aging clockmaker named Elias, renowned for his intricate clocks, takes in a curious boy named Finn as his apprentice. Finn learns the delicate art of clockmaking and discovers a mysterious “Clock of Lost Moments” in the attic, which measures forgotten or regretful moments but cannot bring them back. Elias teaches Finn the value of cherishing present moments. After Elias’s passing, Finn inherits the shop, restores the peculiar clock, and places it in the window. The shop evolves into a haven where people come not only to repair clocks but also to share and mend their own cherished or regretful memories.

Response:
In the town of Willowshade, an old clockmaker named Elias runs a shop filled with intricate clocks. As he ages and his hands tremble, a young boy named Finn arrives, eager to learn the craft. Elias becomes his mentor, teaching him the art of clockmaking. Among the clocks, there is a peculiar one called the Clock of Lost Moments, which measures forgotten moments and regrets rather than time. Elias explains that while time can't be reclaimed, one can make the most of the present. Finn eventually becomes a master clockmaker, inherits the shop after Elias's passing, and restores the Clock of Lost Moments, turning the shop into a place where people share their cherished and regretted moments, thus mending hearts as well as clocks.
