Claude Code by Anthropic

Claude Code is a command-line AI coding agent built by Anthropic that runs directly in your terminal. It can read, write, and edit files across your entire codebase, run shell commands, execute tests, and work through multi-step engineering tasks with minimal hand-holding. It operates on top of Claude's Sonnet and Opus models and is designed to act as an autonomous software engineer rather than just a code autocomplete tool.

Made byAnthropic
Launched2025
CategoryAI Coding Agent / Developer Tool
Best forSoftware engineers who want an agent that can tackle large, multi-file refactors, debug failing test suites, scaffold entire features from a prompt, or investigate unfamiliar codebases — all without leaving the terminal. It is particularly strong for developers already comfortable with CLI workflows and who want less context-switching than browser-based tools require.
PricingUsage-based billing through Anthropic's API; no flat monthly fee for Claude Code itself, but you pay per token consumed by the underlying Claude model. Costs can add up fast on large tasks — a complex session can easily run $1–$10+ depending on context size and model chosen.

Models and pricing

Claude Code with claude-sonnet-4-5 (default)Approximately $0.003 per 1,000 input tokens and $0.015 per 1,000 output tokens (Sonnet 4.5 rates as of mid-2025; verify current rates on Anthropic's pricing page)

Everyday coding tasks: writing functions, fixing bugs, writing tests, moderate refactors

This is the default model Claude Code uses and the sweet spot for most developers. Fast enough to feel interactive, smart enough to handle real codebases, and cheaper than Opus. Start here.

Claude Code with claude-opus-4-5Approximately $0.015 per 1,000 input tokens and $0.075 per 1,000 output tokens (Opus 4.5 rates as of mid-2025; verify current rates on Anthropic's pricing page)

Highly complex architectural tasks, large-scale refactors, or tasks requiring deep multi-step reasoning across a big codebase

Noticeably more capable on hard problems but costs roughly 5x more than Sonnet. Reserve it for genuinely difficult tasks where Sonnet is falling short. A single long Opus session can cost several dollars quickly.

Claude Code via Claude.ai Pro/Max subscriptionClaude.ai Pro is $20/month; Max is $100/month. Claude Code usage counts against included usage limits on these plans.

Developers who want Claude Code access bundled into a flat monthly plan rather than pure API pay-as-you-go billing

If you already pay for Claude.ai Pro or Max, you can access Claude Code without a separate API key up to your plan's usage ceiling. Heavy users will likely hit limits and need API billing anyway. Check Anthropic's current terms — this bundling arrangement launched in 2025 and details may shift.

Which model should you use?

For most developers, use Claude Code with the default Sonnet model for day-to-day work and only switch to Opus when a task is genuinely stumping Sonnet — that single habit will keep your costs reasonable while still getting strong results.
