Compare Grok 4.6 vs. Inkling

Grok 4.6 is an upcoming AI model from xAI that is expected to feature 2 trillion parameters and extend the Grok family’s emphasis on advanced reasoning, coding, agentic systems, and knowledge-based work. Although xAI has not yet released a dedicated product page or complete technical details, public reports indicate that Elon Musk has confirmed the model is under development. Grok 4.6 is expected to expand on Grok 4.5, which xAI positions as its most capable model for software development, autonomous workflows, and complex knowledge tasks. The wider Grok platform already supports conversational assistance, coding, image generation, real-time information from the web and X, and API access for developers. Once officially released, Grok 4.6 could support use cases such as software engineering, research, workflow automation, AI agents, and business productivity. Intended for developers, organizations, and early adopters of xAI technology, it represents the anticipated next stage in the company’s rapidly evolving model lineup.

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.
