The main conclusions from analysis were:

The Pareto frontier for coding tasks (i.e. best quality for a given cost) includes models from OpenAI, Anthropic, and open source. This means today, only a mix of tools can provide frontier performance.

Open models, and GLM 5.2 in particular, are now able to handle even the highest level of task difficulty.

The token price of a model is a poor indicator of actual costs incurred on end-to-end tasks. Larger models can be far more token efficient and have lower overall costs.

The harness a model is called from dramatically impacts cost and quality. In many cases, simple harnesses like Pi performed best on our workloads.
