Met a few devs this weekend…
They still didn’t know about Grok 4 Fast..
Grok 4 Fast is a game-changer:
It has the Highest intelligence density ever - outperforms top models
Ultra cost-effective: Up to 98% cheaper than alternatives
Super-fast output = more productivity, less waiting
It’s wild that this isn’t mainstream yet
If you’re not using Grok 4 Fast, you’re burning both time and money
Grok 4 Fast delivers GPT-5 (High) performance - for just 5% of the cost (95.7% cheaper)... Insane value
Grok 4 Fast costs
- Input tokens: 84% cheaper
- Output tokens: 95% cheaper
- Output speed: 150% faster
GPT-5: $1.25/M input, $10/M output
Grok 4 Fast: $0.20/M input, $0.50/M output
Grok: 344 tokens/s
GPT-5: ~138 tokens/s
Let them know... If anything, Grok 4 Fast’s value is still under-appreciated
