I Built a Game-Changing App for The Finals Using Opus 5 AI - Here's How It Works (2026)

In a world where gaming and technology constantly evolve, it's fascinating to witness the innovative ways individuals leverage AI to enhance their gaming experiences. This article delves into the story of a gamer who, with the help of Anthropic's Opus 5 model, created an app called FISH (Finals Interactive Study Helper) to improve their skills in the game 'The Finals.'

The Birth of FISH

FISH, an app designed to aid strategy and memorization, was born out of the creator's desire for efficiency and expedience in a highly dynamic game like 'The Finals.' Unlike traditional first-person shooters, 'The Finals' demands creative decision-making, and FISH steps in to provide random game scenarios for players to analyze and strategize.

The Power of Simulation

One of FISH's standout features is its ability to simulate comprehensive game scenarios. From player states to team compositions, FISH presents a wide range of possibilities, offering 'answers' or strategies for each situation. This not only helps players memorize game elements but also trains them to make quick, informed decisions.

Coding with Opus 5: A Mixed Bag

While Opus 5 proved efficient in sending more prompts before hitting time limits, it also presented challenges. The model's agents, though capable of setting up complex systems, struggled with basic tasks like web searches. Additionally, Opus 5 often failed to follow instructions outlined in its memories, leading to inconsistencies in its output.

Turning Pro Gameplay into Strategy Drills

A unique aspect of FISH is its ability to provide sophisticated advice based on pro gameplay. By analyzing transcripts from YouTube videos, Opus 5 created a strategy bible, which it then used to tag game states with relevant advice. This feature, though imperfect, offers a deeper level of strategy guidance, going beyond basic mechanics.

Impact on Gameplay

The creator of FISH notes that the app has significantly improved their understanding of 'The Finals.' From recalling a wide range of game elements to making quicker decisions, FISH has been a valuable tool. It reinforces principles and strategies, making it easier to apply them in actual gameplay. Despite being a novice, the creator has seen noticeable improvements in just a week of using FISH.

Final Thoughts

Opus 5, with its efficiency gains and competitive intelligence, is a model worth considering for coding projects. While it may not always outperform GPT-5.6, its strengths lie in certain areas, making it a viable alternative. The story of FISH showcases the potential of AI in gaming, offering a unique perspective on how technology can enhance our hobbies and passions.
