About the model
This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below.
GLM 4.1V 9B Thinking is Z.ai’s reasoning-focused vision-language model built from the GLM 4 9B 0414 foundation. The maker describes a thinking-oriented approach with reinforcement learning to connect visual perception with more complex reasoning. Its published card supports a 64K context and image processing with arbitrary aspect ratios up to 4K resolution.
Connect visible details with the question
Supply an image and a written task that identifies the information to return. A diagram can prompt an explanation of particular relationships; a photograph can ask which visible details support a conclusion. Keep the observation and the interpretation separate so the answer can be checked against the source.
The maker’s inference example combines one image with a question asking for its description. For a more focused task, name the region, object or relationship that matters. Provide conditions that are not visible in the image as separate written facts.
Prepare the image and reasoning task
Use a legible source that preserves the relevant labels and detail. Arbitrary aspect-ratio support helps retain the original composition, while the exact interface determines the input format and preprocessing available for a request. A resolution allowance does not make obscured or missing information visible.
Ask for the required final artifact, such as a description, a comparison or a justified answer. If part of the source is unclear, request that uncertainty alongside the result. A follow-up can identify one disputed detail without changing the underlying question.
Context and edition
The exact hosted profile lists a 64,000-token context and a 32,000-token completion allowance; the maker describes its context as 64K. Use the selected interface’s documented input and response limits for the actual task.
Keep the 9B Thinking identity with the visual sources and answer. The Base model and the separately named Flash profiles have their own identities. The maker’s sample generation budget illustrates one inference task and is not a universal output ceiling.
Practical task
Reason from a written diagram description
Technical example in English
Reason from a written diagram description
Use this written description of diagram D1: tank A feeds filter F; filter F feeds valve V; valve V feeds tank B. A bypass pipe runs from A directly to B. If V is closed, explain which described route could still reach B and what information is missing before concluding liquid actually flows. No image is attached.Expected result
A diagram-linked route explanation separating connectivity from unknown operating conditions.Check the result
The bypass route is identified, while pressure, bypass state and actual flow remain unasserted.Ailoot Ultra · OpenAI Chat POST /v1/chat/completions Pro/THUDM/GLM-4.1V-9B-Thinking
