Editorial excerpt
Claude Sonnet 5.5
AI-assisted, editorially reviewed
A practical coding option to try when Opus spending is difficult to justify.
Sonnet 5.5 is a useful starting point for code review and well-scoped fixes if you want to keep API costs below Opus 5.5. That price difference is a reason to try it, not proof that it will finish every job more cheaply. Check the quality of the completed change and the amount of follow-up work. Its published results also use maximum effort with default fallback; a simpler request may behave differently.
Editorial excerpt
GLM 5.3 Flash
AI-assisted, editorially reviewed
A budget-first API candidate for repeated tasks with clear checks on the output.
GLM 5.3 Flash is a sensible low-budget starting point for repeated text-processing tasks when you can check the results cheaply. Its published token rates are very low, but a small bill is not enough if mistakes create expensive follow-up work. Use a sample with clear acceptance criteria and a way to escalate difficult cases. The available independent results use maximum effort; the Flash name does not establish the speed of your integration.
