XFreeze · x · 2026-07-15
Grok 4.5 secured first place on the Long-Horizon Terminal-Bench, outperforming Claude Fable 5, Claude Opus 4.8, and GPT-5.6-sol.
This benchmark tests whether an AI agent can continuously advance tasks without losing context during up to 90 minutes of terminal operations involving hundreds of dependent steps. The author notes that across 46 high-difficulty tasks and 18 frontier models, Grok 4.5 achieved the highest average reward of 0.505.
The post emphasizes that this demonstrates Grok 4.5's superior performance in complex agentic workflows, real-world coding automation, and difficult engineering tasks.
