Muse Spark Open ✨, Microsoft’s 3T param model 🧠, d1-ultra 💡

GoDaddy’s Developer Platform now bundles hosting, domain registration, and professional email into a single workflow, aiming to streamline AI app deployment. Meanwhile, several new multimodal models have been announced: Muse Spark Open, an 816B‑parameter open‑weight model; Microsoft’s MAI‑Base‑2, a 2.8T‑parameter mixture‑of‑experts model; Liquid AI’s d1‑ultra, a decision model for defect detection; Nvidia’s Nemotron 3.5 series; and Black Forest Labs’ FLUX 3 Image Klein. These models emphasize larger context windows, higher accuracy, and lower costs for real‑world tasks.

GoDaddy’s Developer Platform now integrates hosting, domain registration, and professional email into a single workflow, allowing AI agents to deploy applications, register domains, and set up email with minimal screen switching. The platform’s APIs enable developers to move projects from build to online status efficiently. In parallel, several new multimodal models have been introduced. Muse Spark Open is an 816B‑parameter open‑weight model with 42B active parameters and a 1M‑token context window, designed for coding and long‑horizon agentic tasks, and can run locally on two Apple M5 Ultra Mac Studios using MLX. Microsoft detailed the training of MAI‑Base‑2, a 2.8T‑parameter mixture‑of‑experts model with 80B active parameters that surpassed every open‑weight model in held‑out pre‑training evaluations; the company plans to commercialize frontier models through Foundry. Liquid AI’s d1‑ultra is a multimodal decision model for tasks such as defect detection on circuit boards, processing text and images with better calibration and higher accuracy than earlier models, priced at $0.042 per million input tokens and soon available via Vercel and OpenRouter. Nvidia released Nemotron 3.5 Super VL, scoring 26.5 on the Artificial Analysis Intelligence Index while using fewer output tokens than its predecessor, along with the smaller Nemotron 3.5 Bolt 74B‑A9B and near‑lossless NVFP4 quantized weights. Black Forest Labs launched FLUX 3 Image Klein, a 5.6B‑parameter open‑weight model supporting text‑to‑image generation, editing, native 4K output, and up to ten reference images. These developments reflect a broader industry trend toward larger, more capable multimodal models and tools that lower the barrier to deploying sophisticated AI applications.

Why it matters

The convergence of powerful multimodal models with streamlined deployment tools signals a shift toward more accessible, high‑performance AI solutions for businesses and developers.
