Description

Ultramarine 1 Flash is a powerful hosted large language model that developers and organizations can access via an API, specifically tailored for enhancing AI-driven professional workflows. It caters to various knowledge work sectors including finance, law, consulting, and operations, facilitating tasks such as research, detailed analysis, and the preparation of documentation. Users can submit prompts to the application and receive either streamed or standard responses, while also utilizing reasoning controls, custom tool calls, and the option to request structured outputs. The API is capable of processing image inputs and is compatible with both OpenAI's chat-completion formats and Anthropic Messages, ensuring versatile integration. Developers can interface with the model through several SDKs, including those from OpenAI and Anthropic, as well as the Claude Agent SDK and Claude Code, and can effectively employ it alongside Paper Instruments' suite of tools for Word, PowerPoint, and Excel. Additionally, the billing structure is based on token usage against a prepaid balance, allowing for flexible financial management of resources. This model represents a significant step forward in the automation of high-level professional tasks, pushing the boundaries of what AI can accomplish in workplace settings.
