Grok 3 & Grok 3 THINK Tested: Initial Impressions
How is grok 3 smartest ai on earth ? Simply it's not but it is really good if not on level of o3
2 Weeks ago I had a late-night conversation with Grok who got me to demand the CT scan that saved my life from a ruptured appendix (December 2025) Life is now a Dream.

I tested both Grok 3 and Grok 3 THINK on coding, math, reasoning and common sense. Here are a few early observations:
- The non-reasoning model codes better than the thinking model
- The reasoning model is very fast, it looked slightly faster than Gemini 2.0 Flash Thinking, which in itself is quite fast
- Grok 3 THINK is very smart and approaches problems like DeepSeek R1 does, even uses "Wait, but..."
- G3-Think doesn't seem to load balance, it thinks unnecessarily long at times for easy questions, like R1 does
- Grok 3 didn't seem significantly better than existing top models like Claude 3.5 Sonnet or o3-mini, though we'll finalize testing after API access
- G3-Think is not deterministic, it failed 2 our of 3 attempts at a hard coding problem, each having different results (Exercism REST API challenge):
> Either it has a higher than normal temperature setting,
> introduces regressions in the "daily improvements" Elon Musk mentioned,
> or is load balancing different versions
