Key takeaways
  • GPT-5.6 Sol outperforms GPT-5.5 Pro on MineBench
  • GPT-5.6 Sol has longer inference times than GPT-5.5 Pro
  • GPT-5.6 Sol is significantly more expensive than GPT-5.5 Pro
Full story

GPT-5.6 Sol has been benchmarked on MineBench, showing improved performance compared to GPT-5.5 Pro. However, this comes at the cost of longer inference times and significantly higher costs. The total cost for 15 builds of GPT-5.6 Sol was $710.82, compared to $223.90 for GPT-5.5 Pro. These results suggest that GPT-5.6 Sol is a more powerful model, but also more resource-intensive.

The benchmark was conducted by a Reddit user, who thanked their supporters for helping fund the test. The results provide valuable insights into the performance of these two models and may be useful for developers and researchers looking to choose the best model for their needs.

The implications of these results are significant, as they highlight the trade-offs between model performance and cost. As AI models continue to evolve, it will be essential to consider these factors when selecting the best model for a particular task or application.
