I Made Opus 4.8 and Sonnet 5 Build the Same Apps (RAW RESULTS)

Is Claude Opus 4.8 Still Worth the Price Compared to Sonnet 5?

Introduction to the Comparison

• The video introduces a comparison between Entropic's newly released Sonnet 5 and the existing Claude Opus 4.8, questioning if the latter is still worth its higher price.

• Three projects will be built using both models with identical prompts: a portfolio website, a personal finance app, and a full browser game.

Project Setup

• The presenter emphasizes using Cloud Code for building web apps due to its superior capabilities. Both models (Opus 4.8 and Sonnet 5) are accessible in this environment.

• A fair testing approach is established: same prompt, stack, and effort level without any edits or retries during project builds. The first project is a portfolio website for a freelance designer named Alex Morgan using React and Tailwind CSS.

Building the Portfolio Website

• The detailed prompt includes specifications for sections like hero, about page, featured projects, services, testimonials, contact form, and footer to ensure it looks professional and modern.

• Results from Sonnet 5 show it successfully creates a structured Vite + React + Tailwind project with all required files ready for review at localhost 5180 after completion of the build process.

Performance Metrics of Models

• While waiting for Opus 4.8 to build the same project, performance metrics are discussed: Sonnet 5 shows competitive results in agentic coding (63.2%) compared to Opus 4.8 (69.2%). Pricing differences are highlighted as significant factors influencing choice between models post-introductory period pricing for Sonnet 5 being lower than Opus 4.8’s rates per token usage for input/output tokens respectively at $2/$10 vs $5/$25 initially until August end when prices increase slightly for both models thereafter.

Review of Portfolio Websites

• Upon reviewing both websites:

• Sonnet 5: Features an appealing design with animations but has some elements that appear less polished (e.g., placeholder text). Overall functionality works well including navigation through different sections like testimonials and services seamlessly on mobile devices too.

• Opus 4.8: Presents a darker theme with cleaner UI elements; however similar functionalities exist across both versions making them closely matched in terms of usability despite aesthetic differences noted by user preference towards one over another based on design choices made by each model during development phase.

Building a Functional Personal Finance App

Introduction to Budget Flow App Development

• The second project involves creating "Budget Flow," which requires multiple functionalities such as tracking income/expenses via dashboard totals while ensuring data persistence through local storage upon page refreshes among other features outlined in detail within prompt provided earlier on screen before starting build process again utilizing same method as previous test done previously mentioned above regarding effort levels maintained throughout entire session here too!

Completion of Budget Flow App Using Sonnet 5

• After running through requirements specified earlier including transaction forms/dashboard overview/savings goal tracker etc., successful completion leads us back into localhost where we can see how everything integrates together nicely allowing users easy access managing their finances effectively without hassle whatsoever!

Testing Functionality

• User interactions demonstrate adding transactions smoothly along with visual summaries displayed accurately reflecting changes made dynamically updating charts accordingly showing progress towards savings goals achieved thus far indicating overall success rate high enough warranting further exploration into next steps needed moving forward!

Comparing Budget Flow Apps Built by Both Models

Review of Budget Flow Apps

• Similarities arise when comparing outputs from both models; they share nearly identical layouts featuring dashboards/transaction tabs/saving options available allowing users manage finances efficiently regardless which model chosen ultimately leading us back into question posed earlier whether or not there exists any substantial difference between these two offerings given their close resemblance visually/functionally speaking throughout entire experience encountered thus far!

In conclusion, while both models exhibit strong capabilities in building functional applications like those tested here today—deciding factor may come down primarily cost-effectiveness versus personal preferences regarding aesthetics/design choices made during development processes undertaken separately by each respective AI model involved herein!

Castle Defense Game Development

Overview of the Project

• The project involves building a web app called "Castle Defense," which is a one-shot tower defense game featuring enemy waves and various defender types. The goal is to test the complexity handling capabilities of the development tools used.

Game Features and Requirements

• Key features include:

• Enemy Waves: Players face multiple waves of enemies.

• Defender Types: Four types of defenders (archers, knights, mages) with varying costs and abilities.

• Game Mechanics: Includes gold management, lives, score tracking, upgrades, win/loss screens, pause/restart options, and an activity log.

Technical Implementation

• The game is built using React and Tailwind CSS. The player defends a castle from left-moving enemies by placing defenders strategically on the battlefield. Initial resources include 20 lives and 150 gold. Enemy types are defined with specific attributes such as speed and health.

User Interface Design

• Upon launching the game:

• A start screen provides instructions on gameplay mechanics.

• Players can select defenders from a panel to place on designated tiles in the battlefield.

• Defenders attack automatically without requiring manual aiming.

Gameplay Experience

• During gameplay:

• Players must manage resources effectively while defending against waves of enemies.

• Successful defense results in earning gold for upgrades; failure leads to loss of lives.

• An activity log tracks performance throughout the game sessions.

Comparison Between Sonnet 5 and Opus 4.8

Performance Evaluation

• Both Sonnet 5 and Opus 4.8 produced similar outcomes in terms of functionality for complex builds like Castle Defense.

• While both systems handled complexity well, there were differences noted in design choices where Opus had slight advantages in aesthetics but not functionality overall.

Cost Efficiency Analysis

• In terms of token usage:

• Sonnet was more cost-effective compared to Opus when considering token consumption during development processes.

• For most users focused on budget constraints, Sonnet emerged as the preferable option due to its lower operational costs despite similar performance levels between both models.

Final Thoughts on Development Tools

Recommendations for Users

• For users engaged in simpler projects or those prioritizing cost efficiency, Sonnet is highly recommended due to its effectiveness at lower prices.

• Conversely, if undertaking more complex builds that require extensive coding sessions or advanced functionalities, Opus may be better suited despite higher costs associated with its use.

• Additional resources including prompts for testing are available for further exploration into cloud code applications within these frameworks.
