And now a new DeepSeek model, and appears to be fully open weights. Good benchmarks, but with open models, that isn't always as meaningful. …

The open-source nature of the model makes it potentially more accessible for research and deployment, despite questions about benchmark meaningfulness in evaluating open versus proprietary models.
