HydraFusion: choose a model workflow for a coding task

Three ways to handle a task

Single uses one model. Cascade can inspect an initial result and request repair. Critique uses other models to review work before revision. The October update adds more direct workspace inspection and parallel critics.

Read the history alongside the claims

September forum reports include difficulty seeing intermediate work, model-selection questions and one reported successful bug fix. These describe an earlier preview. They do not measure the current version’s cost or quality across a representative workload.

What Max changes

GitHub describes Max as using more reasoning effort for demanding work. Total cost and completion quality need to be measured on the same task and acceptance criteria before choosing an option.
