Magistral vs. Inkling

Magistral marks the first language model family launched by Mistral AI, focusing on enhanced reasoning abilities and available in two distinct versions: Magistral Small, which is a 24 billion parameter model with open weights under the Apache 2.0 license and can be found on Hugging Face, and Magistral Medium, a more advanced version designed for enterprise use, accessible through Mistral's API, the Le Chat platform, and several leading cloud marketplaces. Tailored for specific sectors, this model excels at transparent, multilingual reasoning across a variety of tasks, including mathematics, physics, structured calculations, programmatic logic, decision trees, and rule-based systems, producing outputs that maintain a coherent thought process in the language preferred by the user, enabling easy tracking and validation of results. The launch of this model signifies a notable shift towards compact yet highly efficient AI reasoning capabilities that are easily interpretable. Presently, Magistral Medium is available in preview on platforms such as Le Chat, the API, SageMaker, WatsonX, Azure AI, and Google Cloud Marketplace. Its architecture is specifically designed for general-purpose tasks that require prolonged cognitive engagement and enhanced precision in comparison to conventional non-reasoning language models. The arrival of Magistral is a landmark achievement that showcases the ongoing evolution towards more sophisticated reasoning in artificial intelligence applications, setting new standards for performance and usability. As more organizations explore these capabilities, the potential impact of Magistral on various industries could be profound.

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.
