xAI Launches Cost-Efficient Grok 4.5
Grok 4.5 costs $2 per million input tokens, undercutting competitors like GPT-5.5 and Fable 5. While it trails in coding benchmarks, it requires 4.2 times fewer tokens than Opus 4.8. xAI trained the model on thousands of Nvidia GB300 GPUs. This pricing strategy prioritizes affordability over raw performance for developers.
