Compare Altar-1 vs. Inkling

Aikido Altar represents a cutting-edge open-weight security framework designed to empower organizations with advanced defensive security intelligence tailored for their infrastructures. This model is particularly suited for environments requiring sovereign security where sensitive assets like source code, architectural documents, vulnerability assessments, and other confidential information must remain within the organization's confines and not be shared with external inference services. Built on the GLM-5.3 architecture, Altar employs techniques such as quantization and expert pruning to compress the model size from an extensive 1.51 TB in full precision down to a more manageable 328 GB, all while maintaining the majority of the original model's reasoning and security features. The model retains 168 out of the original 256 routed experts in each backbone expert layer and adopts a W4A16 representation, enhancing its practicality for security tasks that require handling extensive and evolving context windows. The calibration of expert selection was conducted using internal pentesting data and multilingual sources, ensuring that no client information was utilized, which upholds the integrity of cybersecurity, programming, and linguistic capabilities. This innovative approach not only streamlines deployment but also fortifies the organization's security posture against emerging threats.

Inkling is Thinking Machines’ open-weights foundation model built for customization, multimodal reasoning, and agentic AI workflows. The model uses a Mixture-of-Experts architecture with 975 billion total parameters and 41 billion active parameters, making it large in capacity while activating only a subset of experts per token. Inkling supports up to a 1 million token context window and was pretrained on 45 trillion tokens spanning text, images, audio, and video. It is designed as a broad generalist model with strengths across coding, reasoning, instruction following, factuality, tool use, vision, audio understanding, forecasting, and safety. Developers can tune its thinking effort to trade off latency, cost, and performance, which is useful for production systems that need efficient reasoning at scale. Inkling can be fine-tuned on Tinker, tested in the Inkling Playground, and deployed through partners such as TogetherAI, Fireworks, Modal, Databricks, Baseten, vLLM, SGLang, llama.cpp, and Hugging Face transformers. The model can generate applications, operate tools, create styled artifacts, reason over visual and audio inputs, and support long refinement loops for collaborative work. Thinking Machines also previewed Inkling-Small, a lighter Mixture-of-Experts model with 276 billion total parameters and 12 billion active parameters for lower-cost and lower-latency workloads. By combining open weights, multimodal training, agentic capabilities, efficient reasoning, and fine-tuning support, Inkling gives builders a flexible AI foundation for specialized products and workflows.
