Scores are vendor-reported unless marked independent, as of September 2026. Labs use different agent harnesses, reasoning settings, and benchmark versions, so treat cross-lab gaps of a few points as roughly equal and test on your own workload.
Which should you use?
DeepSeek V4.1 leans toward long-context code generation, while GLM 5.3 is a strong pick for repo-scale coding & terminal agents. Because both run on kryyt behind one API, you can route each request to whichever fits — no second integration.
FAQ
Is DeepSeek V4.1 better than GLM 5.3?
They target different strengths. DeepSeek V4.1 is strong at long-context code generation; GLM 5.3 at repo-scale coding & terminal agents. The best choice depends on your task, and kryyt lets you use both.
Can I use DeepSeek V4.1 and GLM 5.3 together?
Yes. Both are available through the same kryyt endpoint and key — switch by changing the model string per request.
How are they priced on kryyt?
