Google Gemini’s Pokémon Win: The Hidden Downsides
▼ Summary
– Anthropic’s Claude model struggled to beat Pokémon Red, while Google’s Gemini 2.5 completed Pokémon Blue after 106,000 actions.
– Gemini’s success shouldn’t be used to directly compare AI models due to significant outside help it received.
– The developer notes Pokémon is an unreliable benchmark for LLMs, as models like Claude and Gemini use different tools and frameworks.
– Gemini’s performance benefited from a custom “agent harness” that provided extra game information and memory aids.
– The agent harness helped Gemini summarize past actions and interact with the game more effectively than Claude.
Google’s Gemini AI recently made headlines by completing Pokémon Blue, but the achievement comes with important qualifications that reveal limitations in current AI capabilities. While the milestone impressed many—including Google’s top executives—the victory wasn’t solely due to raw artificial intelligence. The system relied heavily on specialized tools and frameworks unavailable to other models attempting similar gaming challenges.
The project’s creator, independent developer JoelZ, emphasizes that Pokémon makes a poor benchmark for comparing large language models. Each AI system operates with distinct frameworks and receives different types of game data, making direct performance comparisons meaningless. Claude’s earlier attempts struggled partly because its technical setup lacked critical features that Gemini’s implementation enjoyed.
What truly set Gemini apart was its custom “agent harness”—a sophisticated support system feeding the AI crucial gameplay information. This framework continuously updated the model about in-game conditions, helped maintain context about previous actions, and provided fundamental navigation tools. Without this specialized assistance, Gemini would have faced the same struggles as other models in interpreting the game’s basic mechanics.
The achievement highlights how external scaffolding often determines AI performance more than the underlying model’s intelligence. While impressive, Gemini’s Pokémon victory says less about general AI capabilities and more about how carefully engineered support systems can enable specific accomplishments. As researchers continue pushing boundaries, such distinctions become increasingly important for understanding true progress in artificial intelligence development.
