Grok upgrades
xlr8harder@xlr8harder· Nov 7, 2025Someone from xAI reached out and asked me to retest grok-4-fast, because they've improved the injected system prompts. Huge improvement!
grok-4-fast-reasoning: 77.5% -> 94.1%
grok-4-fast-non-reasoning: 77.9 -> 97.9%
I really appreciate that xAI takes this topic seriously.
