Amazon Titan (Amazon) and Grok-2 (xAI) are both frontier AI models. Amazon Titan was published in September 2023 and Grok-2 in August 2024.
Grok-2 was trained on 3 x 10^25 FLOP, about 6.2x the compute of Amazon Titan at 4.8 x 10^24 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.
