Inkling vs. GPT-5.4 mini

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.

GPT-5.4 mini is a high-performance, efficient AI model designed to handle complex tasks while maintaining low latency and cost. It is part of the GPT-5.4 model family and brings many of the strengths of larger models into a more lightweight and faster format. The model is optimized for coding, reasoning, and multimodal tasks, allowing it to work with both text and image inputs effectively. It supports advanced features such as tool calling, function execution, and integration with external systems, making it highly adaptable for real-world applications. GPT-5.4 mini is particularly effective in scenarios where speed is critical, such as coding assistants, real-time decision systems, and interactive AI tools. It significantly improves upon earlier mini models by delivering faster response times and stronger performance across multiple benchmarks. The model is also well-suited for use in subagent systems, where it can handle smaller, specialized tasks within a larger AI workflow. This allows developers to combine it with larger models for more efficient and scalable architectures. GPT-5.4 mini performs well in tasks such as code generation, debugging, data processing, and automation. Its ability to interpret screenshots and visual data further enhances its usefulness in multimodal applications. With a large context window and strong reasoning capabilities, it can handle complex inputs and long-form interactions. At the same time, its efficiency makes it cost-effective for high-volume deployments. By balancing speed, capability, and scalability, GPT-5.4 mini enables developers to build powerful AI solutions that are both responsive and economical.
