Grok Updates
ALPrompt scores (base model/non-reasoning):
2024H1=5/5
2024H2=2/5 (4/5 with reasoning)
2025H1=1/5. First frontier model to consistently admit that it doesn’t know the answer to something.
GPQA Grok-3=75.4%, Grok-3 + reasoning + ITC=84.6%
MMLU-Pro Grok-3=79.9%
13/Feb/2025: xAI CEO: ‘Grok 3 has very powerful reasoning capabilities, so in the tests that we’ve done thus far, Grok 3 is outperforming anything that’s been released, that we’re aware of, so that’s a good sign’ (Reuters, 13/Feb/2025)
9/Feb/2025: On Chatbot Arena (formerly LMSYS), ‘Chocolate’ model (said to be Grok-3) performs very poorly. For ALPrompt2024H2, GPT-4o=4/5. Chocolate=1/5.
8/Dec/2024: xAI developer Chris Park: ‘Grok 2 + Aurora [xAI’s own image generator] is now available with your X app in the model selector. Oh, by the way, Grok 3 is coming.’
