Amazon Titan vs Grok 3

Amazon Titan (Amazon) and Grok 3 (xAI) are both frontier AI models. Amazon Titan was published in September 2023 and Grok 3 in February 2025.

Grok 3 was trained on 3.5×10²⁶ FLOP, about 72.9x the compute of Amazon Titan at 4.8×10²⁴ FLOP. Training compute is the closest available proxy for how much was invested in a model, though it says nothing on its own about how well that compute was spent.

These two models share no benchmark on which both have been scored, so no direct performance comparison is possible here. The specification table below is a comparison of inputs, not of results.
