Claude and Claude Code

Claude is a family of large language models and service developed and hosted by Anthropic, an AI safety and research company building reliable, interpretable, and steerable AI systems. Available through Anthropic's web chat products and a commercial API, Claude accepts text prompts and structured inputs or file attachments via the API and returns natural-language and code outputs for tasks such as coding, summarization, document Q&A, and general business and productivity workflows. It is used inside Anthropic products such as Claude Code, by third-party services via Anthropic's API and enterprise agreements, and as an alternative model provider for the model-agnostic Strands Agents framework. Claude can also power applications such as banking assistants, whose generations can be traced as part of an AI application evaluation workflow.

Claude 5.1 is described in the supplied video evidence as an Anthropic AI model for programming, scientific research, and agentic tasks. The video claims that it can work continuously for dozens of hours on codebases and multistep research, with separate lower pricing for cached, ordinary, and complex agent tasks.

Claude for Excel is an AI tool that brings Claude into Microsoft Excel. The video describes it as helping Citadel's investment professionals test, build, and trust their spreadsheet work.

Claude for Financial Services is an Anthropic repository of reference agents, skills, slash commands, and data connectors for investment banking, equity research, private equity, fund administration, wealth management, and related financial-services workflows. Its named agents cover tasks such as pitch-deck preparation, market research, earnings review, financial modeling, valuation review, general-ledger reconciliation, month-end close, statement auditing, and KYC screening. The components can be installed as Claude Cowork or Claude Code plugins, or deployed as Claude Managed Agents through the Anthropic API. Agents bundle workflow-specific skills; vertical plugins provide reusable skills and commands such as comparable-company analysis, DCF and LBO modeling, Excel auditing, earnings analysis, diligence checklists, and investment-committee memo drafting. Centralized MCP connectors link the skills to external financial-data and document providers, subject to each provider's subscription or API-key requirements. The repository also includes managed-agent cookbooks, deployment and validation scripts, partner-authored plugins, and tooling for provisioning the Claude Microsoft 365 add-in. It is file-based, using Markdown, YAML, and JSON without a build step, and is distributed under the Apache License 2.0. The repository states that its agents draft work product for qualified-professional review and do not make investment recommendations, execute transactions, bind risk, post to a ledger, or approve onboarding.

Claude Opus is an AI model developed by Anthropic, the company behind the Claude assistant. It is part of the Claude family and is designed for complex language tasks, including research and content generation. The model is available through Anthropic's platform.
