Claude 3.5 Sonnet vs Inflection-2

Claude 3.5 Sonnet (Anthropic) and Inflection-2 (Inflection AI) are both frontier AI models. Claude 3.5 Sonnet was published in June 2024 and Inflection-2 in November 2023.

Claude 3.5 Sonnet was trained on 2.7×10²⁵ FLOP, about 2.7x the compute of Inflection-2 at 10²⁵ 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.
