$20/month Pro; $100/month Max 5x; $200/month Max 20x; API from $5/$25 per million tokens

Project-level agentic operation — reads full codebase, plans multi-file changes, executes and tests at scale
Dreaming — agents review past sessions, extract patterns, write plain-text playbooks for future sessions (Harvey: 6x task completion)
Outcomes — self-grading rubrics: define success criteria, separate grader agent evaluates each run
Multi-Agent Orchestration — commander + parallel specialist agents with independent context windows; Netflix running hundreds of builds simultaneously
Native toolchain integration — GitHub CLI, Kubernetes, GitHub/GitLab CI monitoring and auto-fix
Enterprise deployment — Stripe across 1,370 engineers, zero-config enterprise binary
$20/month Pro / $100/month Max 5x / $200/month Max 20x / API from $5/$25 per million tokens

Project-level agentic operation — not line completion, full codebase planning and execution
Dreaming feature enables genuine self-improvement: agents learn from past sessions and write practical playbooks
Outcomes self-grading means measurable success criteria instead of "close enough"
Multi-agent orchestration handles parallel workloads at enterprise scale
Native GitHub/GitLab CLI integration eliminates manual command memorization
Production deployments with real metrics: 6x task completion (Harvey), 80% incident reduction (Ramp), 4-day Scala-to-Java migration at 10 engineer-weeks scale
"Letting Claude cook" reliably handles the full build-test-fix cycle for well-scoped tasks

Heavily AI-generated code requires rigorous human review — tool writes, you approve
Dreaming requires Managed Agents cloud setup — significantly different from standalone CLI usage
Multi-agent orchestration and outcomes are architecturally complex — not plug-and-play
Poorly scoped goals lead to productive but incorrect iterations that waste compute
No built-in code review UI — reviewing AI-generated code commit by commit is still manual
Max plans are cost-effective vs. API burns, but $100-200/month is material for individual developers
