Claude Opus 4.7 — our take
Claude Opus 4.7 is a hosted-only model from Anthropic, so using it means choosing a host rather than running it yourself. Its measured strength is set-piece reasoning and maths; agentic work in an existing codebase is where it measures weakest.
full breakdown →GLM 5.3 Flash — our take
GLM 5.3 Flash is a downloadable model you can run yourself, and it is at its best when the job is agentic: picking the right tool and finishing the task. It is at its worst when the job is holding to a format under instruction, and we list no licence for it, so the terms need checking at the source.
