Anthropic has launched a public beta for its AI model Claude, featuring persistent memory, which could significantly impact its performance on the LMSYS leaderboard. This development comes as Polymarket contracts predict Anthropic will have the top AI model by the end of April 2026, with a 15% improvement expected. The contract, which settles on April 30, has seen low trading volume, suggesting that even small trades could influence market prices. Persistent memory allows AI models to retain contextual information across sessions, enhancing multi-round evaluations crucial for rankings. This capability positions Claude to better compete with rivals like OpenAI and Google DeepMind. As the final results approach, traders are advised to monitor Claude's leaderboard position closely, as any new model releases from competitors could affect outcomes.
