What each model is
GLM 5.3 Open
GLM-5.3 is a large-scale reasoning model from Z.ai, built for complex software engineering and long-horizon agent tasks. It supports text input and output with a 1M-token context window, and improves...
o1-pro (batch) Paid
The o1 series of models are trained with reinforcement learning to think before they answer and perform complex reasoning. The o1-pro model uses more compute to think harder and provide...

Frequently asked questions
Is GLM 5.3 as good as o1-pro (batch)?
GLM 5.3 is open-weight and competitive on many tasks, but o1-pro (batch) may still lead on the hardest reasoning and agentic work. The gap keeps narrowing — benchmark both on your actual use case before deciding.
Can I run GLM 5.3 locally?
Yes. GLM 5.3 has open weights, so you can self-host it on your own GPUs or run it via a low-cost API. o1-pro (batch) is API-only and cannot be self-hosted.
How much cheaper is GLM 5.3?
GLM 5.3 costs $4.4/M output vs $300/M for o1-pro (batch) — roughly 68x cheaper via API, and free if you self-host.
GLM 5.3 vs o1-pro (batch) — which should I pick in 2026?
Choose GLM 5.3 if you want to self-host, keep your data private and skip per-token fees — it's open-weight and runs on your own hardware. Choose o1-pro (batch) if you want frontier capability through a managed API with zero infrastructure to run.
