Inkling vs. GLM-4.5V

Inkling is an open-weights multimodal AI model from Thinking Machines built to support customization, agentic workflows, coding, reasoning, vision, audio, and enterprise AI use cases. The model is a Mixture-of-Experts transformer with 975 billion total parameters, 41 billion active parameters, 256 routed experts per MoE layer, and six routed experts active per token. It supports context windows up to 1 million tokens and was pretrained on 45 trillion tokens across text, images, audio, and video. Inkling is designed as a broad foundation model rather than a narrowly optimized benchmark model, giving it balanced capabilities across reasoning, coding, factuality, instruction following, vision, audio, tool use, and safety. Its controllable thinking effort lets developers adjust how much computation and generated reasoning the model uses, helping teams balance quality, latency, and cost for different production needs. The model can run agentic coding tasks, use tools, create web apps, generate polished multi-page artifacts, reason over long contexts, and work through iterative refinement loops. For multimodal tasks, Inkling can process images, answer questions about visual content, transcribe and reason over audio, follow spoken instructions, and combine visual reasoning with code-based tools such as Python. Thinking Machines trained Inkling for calibration, instruction following, factual reliability, refusal behavior, and safety across multiple modalities, including evaluations for dangerous capabilities and human-AI threat vectors. Inkling is available on Tinker for fine-tuning, with 64K and 256K context options, an Inkling Playground for testing, cookbook recipes, and support for multimodal post-training workflows. Its full weights are available on Hugging Face, and deployment support is available through APIs and infrastructure partners such as TogetherAI, Fireworks, Modal, Databricks, Baseten, SGLang, vLLM, llama.cpp, and transformers.

The GLM-4.5V model emerges as a significant advancement over its predecessor, the GLM-4.5-Air, featuring a sophisticated Mixture-of-Experts (MoE) architecture that includes an impressive total of 106 billion parameters, with 12 billion allocated specifically for activation purposes. This model is distinguished by its superior performance among open-source vision-language models (VLMs) of similar scale, excelling in 42 public benchmarks across a wide range of applications, including images, videos, documents, and GUI interactions. It offers a comprehensive suite of multimodal capabilities, tackling image reasoning tasks like scene understanding, spatial recognition, and multi-image analysis, while also addressing video comprehension challenges such as segmentation and event recognition. In addition, it demonstrates remarkable proficiency in deciphering intricate charts and lengthy documents, which supports GUI-agent workflows through functionalities like screen reading and desktop automation, along with providing precise visual grounding by identifying objects and creating bounding boxes. The introduction of a unique "Thinking Mode" switch further enhances the user experience, enabling users to choose between quick responses or more deliberate reasoning tailored to specific situations. This innovative addition not only underscores the versatility of GLM-4.5V but also highlights its adaptability to meet diverse user requirements, making it a powerful tool in the realm of multimodal AI solutions. Furthermore, the model’s ability to seamlessly integrate into various applications signifies its potential for widespread adoption in both research and practical environments.
