Algorithmic pairing — assembled from recorded fields, not hand-checked
AI21 Labs
Agent platform
Planning system that runs multi-step tasks against a company's own data and validates the output against stated requirements.
Model API
Hosted developer platform providing API/SDK access to AI21's Jamba foundation models with metered token pricing, a playground, file library, and web/file search tools.
Anthropic
Agent platform
Hosted API offering a pre-built configurable agent harness with managed sandboxes and persistent sessions for long-running asynchronous agent tasks, billed separately from token usage.
Model API
No counterpart
AI21 Labs sells these in a stack layer with no product recorded for Anthropic yet — nothing on the other side to compare them against.
API service
A drop-in endpoint that sits in front of an agent's model calls and cuts token spend — adaptive routing, context compaction, trajectory-aware savings decisions and caching — while validating output quality against coding benchmarks.
Data service
A dedicated model-customization service in which AI21 trains specialized models on a client's own data, with methodology transfer so the client can run subsequent training rounds in-house.

Application
Assistant for chat, document analysis and coding, used in the browser and in desktop and mobile apps.
Lets users collaborate with Claude to create on-brand visual work (decks, prototypes, wireframes, marketing collateral) with design-system import and Claude Code integration via /design-sync.
Desktop application for scientific research that runs analyses, searches scientific databases and traces work from data wrangling through to publication.
Application that scans codebases for high-severity vulnerabilities, validates findings by adversarial verification and recommends patches for review, with a companion Claude Code plugin.
Claude working inside Excel, PowerPoint, Word and Outlook with context carried across the documents — preserving templates and house styles and showing every edit as tracked changes, highlighted cells or draft emails.
Claude tagged as @Claude inside Slack threads and channels: it reads thread context and replies in real time, analyses conversations, pulls data, drafts content, monitors channels, triages alerts and runs standing instructions without leaving Slack.
AI agent
Coding agent that works on a codebase from the terminal, an IDE extension and a desktop app.
Agentic task app in which Claude works asynchronously across a user's files and tools toward a stated goal, checked in on from desktop, web or phone.
Browser extension that lets Claude act inside Chrome on the user's behalf — reading pages, clicking, typing and filling forms to work through multi-step web tasks without approving each step, with the user keeping control of what it may do.
Developer tool
Python and TypeScript library that runs the same agent loop, tools and context management that power Claude Code, so developers can embed the loop in their own process rather than calling the API directly.
