Databricks CEO Ali Ghodsi shared internal benchmark results last week aimed at managing AI costs for its 3,000 software engineers. The tests compared the performance of different AI models on real programming tasks. The results showed that 'open-source models, especially GLM 5.2, can now handle the highest difficulty coding tasks' with total costs lower than proprietary models from Anthropic and OpenAI. GLM 5.2 comes from Chinese AI company Z.ai and is an open-weight model.
The tests also found that the choice of agentic coding tools (e.g., Codex, Claude Code) is as important as the model itself for cost. The open-source tool Pi performed best in context management, achieving the lowest cost while maintaining quality. Ghodsi concluded in his blog post: 'The lesson is not that one tool is always cheaper, or that native tools are worse; rather, model selection is only part of the puzzle.'
This finding reinforces Databricks' image as an advocate for enterprise AI cost control and also confirms a major trend in 2026: enterprises are increasingly adopting cheaper Chinese open-weight models.
