XAI GAVE US EARLY ACCESS TO GROK 4 - AND THE RESULTS ARE IN

Summary from the TLDR newsletter

According to new benchmark tests, Grok 4 is now the leading AI model. Grok 4 is a reasoning model that costs $3 per million input tokens and $15 per million output tokens. It is expected to be available via the xAI API, the Grok chatbot on X, and potentially on Microsoft Azure AI Foundry. xAI's API serves Grok 4 at 75 tokens per second, which is slower than OpenAI's o3 but faster than Anthropic's Claude 4 Opus Thinking.
