Multi-Challenge
MultiChallenge is a realistic multi-turn conversation evaluation benchmark that challenges frontier LLMs across four key categories: instruction retention (maintaining instructions throughout conversations), inference memory (recalling and connecting details from previous turns), reliable versioned editing (adapting to evolving instructions during collaborative editing), and self-coherence (avoiding contradictions in responses). The benchmark evaluates models on sustained, contextually complex dialogues across diverse topics including travel planning, technical documentation, and professional communication.
GPT-5 from OpenAI currently leads the Multi-Challenge leaderboard with a score of 0.696 across 24 evaluated AI models.
GPT-5 leads with 69.6%, followed by 
Qwen3.5-397B-A17B at 67.6% and 
Step3-VL-10B at 62.6%.
