What is Nemotron 3.5 Bolt?

NVIDIA Nemotron 3.5 Bolt is a family of open artificial intelligence models developed to provide efficient reasoning, autonomous agent capabilities, and conversational intelligence on local computing hardware. Introduced in October 2026, the series includes Nemotron 3.5 Bolt 74B-A9B 24GB and Nemotron 3.5 Bolt E4B 4GB. The 74B-A9B variant uses a mixture-of-experts architecture containing 74 billion total parameters, with approximately 9 billion parameters activated during inference. Its native 2-bit quantization enables deployment within approximately 24GB of memory while preserving resources for other applications. The model is designed for agentic workflows that require reasoning, instruction following, tool interactions, and execution of multiple connected tasks. Developers can use Bolt 74B-A9B with local agent frameworks to conduct web research, generate software, analyze code, investigate programming errors, and perform debugging activities. NVIDIA reports strong results on agent benchmarks including PinchBench and BrowseComp, which evaluate autonomous task completion and information retrieval capabilities. The smaller Bolt E4B variant is designed for low-latency conversational AI, supporting local voice assistants, interactive game characters, and embedded interfaces. Its 4GB memory footprint makes it suitable for compatible GeForce RTX, NVIDIA Jetson, and DGX Spark systems that require efficient local inference. Running these models locally allows organizations to retain greater control over sensitive application data, reduce dependence on cloud inference, and integrate AI capabilities into existing software environments. Nemotron 3.5 Bolt 74B-A9B is available through Hugging Face with support for llama.cpp, Ollama, LM Studio, Unsloth, and vLLM, while Bolt E4B is scheduled for release on October 23, 2026.

What is Holo2?

The Holo2 model series from H Company strikes an excellent balance between cost-effectiveness and high performance in vision-language models tailored for computer-based agents capable of navigating, localizing interface elements, and operating across web, desktop, and mobile environments. This latest lineup, which features configurations of 4 billion, 8 billion, and 30 billion parameters, builds on the groundwork established by the previous Holo1 and Holo1.5 models, ensuring a solid foundation in user interface interaction while significantly enhancing navigation capabilities. By employing a mixture-of-experts (MoE) architecture, the Holo2 models selectively activate only the parameters essential for specific tasks, thereby optimizing operational efficiency. Trained on meticulously selected datasets centered on localization and agent functionality, these models are set to seamlessly succeed their predecessors. They also support smooth inference in environments that are compatible with Qwen3-VL models and can be effortlessly integrated into agentic workflows, such as Surfer 2. In performance tests, the Holo2-30B-A3B model achieved remarkable benchmarks, scoring 66.1% on the ScreenSpot-Pro evaluation and 76.1% on the OSWorld-G benchmark, firmly positioning itself as a frontrunner in the UI localization field. The technological advancements embedded in the Holo2 models not only enhance their capabilities but also make them an attractive option for developers aiming to boost the performance and efficiency of their applications. As the demand for sophisticated user interface solutions continues to grow, the Holo2 models stand ready to meet the diverse needs of the market.
