What is Ultramarine 1 Flash?

Ultramarine 1 Flash serves as a robust hosted large language model accessible to both developers and organizations through an API, designed specifically to enhance workflows driven by AI in professional environments. It supports a range of industries such as finance, law, consulting, and operations, aiding in activities like research, comprehensive analysis, and document preparation. Users can interact with the application by submitting prompts and can expect either streamed or standard responses, while also having access to reasoning controls, custom tool calls, and structured output options. The API additionally supports the processing of image inputs and is compatible with OpenAI's chat-completion formats as well as Anthropic Messages, promoting flexible integration across various platforms. Developers can connect with the model using multiple SDKs, including those from OpenAI and Anthropic, as well as the Claude Agent SDK and Claude Code, allowing for seamless collaboration with Paper Instruments' tools for Word, PowerPoint, and Excel. Furthermore, the billing system operates on a token-based model against a prepaid balance, providing users with flexible financial resource management. This model not only advances the automation of sophisticated professional tasks but also challenges the conventional limits of AI capabilities in workplace scenarios. As a result, it encourages organizations to rethink their approach to integrating AI technologies into their daily operations.

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.
