Description
Claude Opus 5.5 is a frontier AI model from Anthropic built for coding, research, business analysis, computer use, and complex agentic workflows. The model is particularly suited to long-running software engineering tasks such as codebase migrations, audits, debugging, optimization, and large-scale refactoring. Anthropic also positions Opus 5.5 for professional knowledge work including financial analysis, legal workflows, research reports, spreadsheets, presentations, and business automation. Compared with Claude Opus 5, the model is designed to use fewer tokens, generate responses more quickly, and reduce typical workload costs. Its communication style has also been refined to make outputs clearer, easier to scan, and more consistent with user-defined writing requirements. Opus 5.5 includes stronger defenses against prompt injection and is less likely to take irreversible or out-of-bounds actions during autonomous tasks. Enterprise safety features include action classification, an auditable open-source sandbox, code review capabilities, preserved thinking protections, and configurable safeguards for sensitive domains. The model supports zero data retention and is available with additional verification programs for vetted life sciences and cybersecurity organizations. Claude Opus 5.5 is accessible through Anthropic’s applications and API as well as AWS, Google Cloud, and Microsoft Azure.
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.
