How AI Generates Battle Narratives in TextFight
A deep dive into the technology behind TextFight battle narratives. Learn how OpenAI models evaluate fighter descriptions, weigh strategic factors, and produce unique stories for every fight.

The Engine Behind Every Battle
When two fighters step into the TextFight arena, something remarkable happens behind the scenes. Within seconds, an advanced AI model reads both fighter descriptions, evaluates dozens of factors, and produces a battle narrative that reads like a short story. The process is fast, but the engineering that makes it possible is anything but simple.
TextFight uses OpenAI large language models as its narrative engine. These models have been trained on vast amounts of text data, which gives them an intuitive understanding of storytelling structure, cause and effect, and the way fictional fighters interact. The TextFight team layers custom prompts and evaluation criteria on top of this foundation to create a judging system tailored specifically for competitive text battles.
Prompt Engineering and Battle Instructions
The quality of an AI-generated narrative depends heavily on the instructions the model receives. In TextFight, the battle prompt is a carefully crafted document that tells the AI exactly how to behave. It specifies the evaluation criteria, the tone of the narrative, and the format of the output. This prompt has been refined through thousands of test battles to ensure consistent, fair, and entertaining results.
The prompt instructs the AI to evaluate fighters across several dimensions. Creativity is weighted heavily because the game rewards original thinking. Strategic coherence matters because a fighter whose abilities logically complement each other should outperform one with random, disconnected powers. Fighter consistency ensures that the description paints a believable figure, even in a fantastical setting. And narrative potential measures how interesting the resulting story can be when both fighters collide.
These criteria work together to prevent simple power escalation. A fighter described as an omnipotent god who destroys everything will score poorly on creativity and narrative potential because there is no interesting story to tell. Meanwhile, a street magician who uses misdirection and sleight of hand in combat creates rich narrative opportunities that the AI recognizes and rewards.
How the AI Reads Fighter Descriptions
When the AI receives two fighter descriptions, it does not simply compare word counts or scan for keywords. It builds an internal representation of each fighter, understanding their abilities, personality, weaknesses, and fighting style. This is possible because large language models excel at reading comprehension and inference.
For example, if a fighter is described as a frost mage who draws power from emotional calm, the AI understands that this fighter would be vulnerable to opponents who specialize in psychological disruption. If the opposing fighter is a chaos demon that feeds on fear and confusion, the AI can construct a narrative around that natural tension. These emergent interactions are what make battles feel organic rather than formulaic.
The 300-character limit plays an important role here. It forces players to be concise, which actually helps the AI. Shorter, focused descriptions with clear details are easier for the model to parse accurately than long, rambling passages full of contradictions. This alignment between game design and AI capability is deliberate.
Narrative Generation Step by Step
Once the AI has analyzed both fighters, it generates the battle narrative in a structured sequence. First, it establishes the setting, describing the arena or environment where the fight takes place. This adds variety and context, even though the players did not specify a location.
Next, the narrative introduces both fighters, often highlighting the contrast between them. A hulking mechanical war machine facing off against a tiny woodland sprite creates immediate dramatic tension that the AI uses to hook the reader.
The middle of the narrative depicts the exchange of abilities and strategies. The AI shows how each fighter attempts to use their strengths while coping with the opponent. This section is where the most creative writing happens, because the AI needs to invent specific moments and turning points that feel natural given the source descriptions.
Finally, the narrative reaches a climax and delivers a verdict. The winner is announced, but the losing fighter is treated with respect. The AI explains what the loser did well and why the winner ultimately prevailed. This approach keeps both players engaged and encourages them to refine their fighters rather than feel frustrated by a loss.
Ensuring Fairness and Reducing Bias
One of the biggest challenges in AI-judged competition is ensuring that the model does not favor certain types of descriptions over others for reasons unrelated to quality. The TextFight team addresses this through several mechanisms.
Position randomization is one technique. The order in which fighters are presented to the AI is shuffled so that neither player benefits from being read first or second. Prompt calibration involves running large batches of test battles with known quality levels and adjusting the instructions until the AI consistently ranks them correctly.
The team also monitors aggregate statistics. If a certain category of fighter, say sci-fi robots, starts winning at a disproportionate rate, the prompts are reviewed to ensure the AI is not biased toward that genre. The goal is a system where any well-crafted fighter has a fair shot regardless of theme or setting.
Why Every Battle Feels Different
A common concern with AI-generated content is repetition. If the same two fighters fight multiple times, will the narrative be identical? In TextFight, the answer is no. Large language models incorporate a degree of randomness in their text generation controlled by a parameter called temperature. This means that even with identical inputs, the output will vary.
Beyond temperature, the richness of the prompt and the open-ended nature of storytelling mean that the AI has many valid paths it can take. One battle might focus on a dramatic opening salvo, while a rematch between the same fighters might emphasize a slow tactical buildup. This variability keeps the game feeling fresh and encourages players to experiment with the same fighters across multiple fights.
The Continuous Evolution of the Battle Engine
The narrative engine is not a static system. The TextFight development team continuously refines the prompts, tests new model versions, and incorporates player feedback. When players report that a narrative felt unfair or that the AI misunderstood a fighter, that feedback is used to improve future battles.
As AI technology advances, the narratives will only get better. Models with larger context windows can consider more information. Models with improved reasoning can make more nuanced judgments. And models with better creative writing capabilities can produce stories that rival human-authored fiction. For TextFight players, this means the game will keep getting more engaging over time without requiring any changes to the core gameplay loop.
Understanding how the AI works does not diminish the magic of a great battle narrative. If anything, it deepens your appreciation for the craft involved in writing a winning fighter description, because you begin to see the game not just as a contest of imagination but as a dialogue between human creativity and artificial intelligence.
