Deep dive
The capability footprint differs most on vision: AutoGLM Phone 9B Multilingual, multimodal input: AutoGLM Phone 9B Multilingual, reasoning mode: GLM-5.1, structured outputs: GLM-5.1, and code execution: GLM-5.1. Both models share function calling and tool use, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.
For cost, AutoGLM Phone 9B Multilingual lists $0.04/1M input and $0.14/1M output tokens on the cheapest tracked provider, while GLM-5.1 lists $0.98/1M input and $3.08/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts AutoGLM Phone 9B Multilingual lower by about $1.54 per million blended tokens. Availability is 1 providers versus 5, so concentration risk also matters.
Choose AutoGLM Phone 9B Multilingual when vision-heavy evaluation and lower input-token cost are central to the workload. Choose GLM-5.1 when coding workflow support, larger context windows, and broader provider choice are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship. This keeps the decision grounded in measurable tradeoffs instead of brand-level assumptions.
FAQ
Which has a larger context window, AutoGLM Phone 9B Multilingual or GLM-5.1?
GLM-5.1 supports 200k tokens, while AutoGLM Phone 9B Multilingual supports 66k tokens. That gap matters most for long documents, large codebases, retrieval-heavy agents, and conversations where earlier context must remain visible.
