AI Coding Tools Cost Compared: Copilot, Cursor, Claude Code, and Codex

Four tools, four completely different answers to the same question: what does it cost to let AI write your code? GitHub Copilot bundles unlimited autocomplete with a credit pool. Cursor sells you a dollar-value pool and an unlimited router. Claude Code shares one usage budget across everything Anthropic makes. Codex rides along inside your ChatGPT plan. Same job, four billing philosophies.

And in 2026 they are quietly converging. All four have drifted toward usage-based, token-metered billing, where what you pay tracks how much AI work you actually do, not a flat monthly number. That makes a straight price comparison less useful than it looks, so this guide covers all four: their plans, how each one meters, what really drives the bill, and which is cheapest for the way you work.

How AI Coding Tools Charge in 2026

A year ago these tools sold flat subscriptions with fuzzy “fair use” limits. Now they meter. The shift, driven by the token cost of the models underneath, means every vendor separates cheap, high-frequency work from expensive, agentic work. Autocomplete and lightweight edits are usually free or unlimited; agent runs, chat, and frontier-model calls draw down a metered allowance. This is the same move to token-metered billing reshaping all of AI, which we cover in AI costs are cloud costs now. The upshot for buyers: your bill now depends on behavior, especially which model you point at each task.

The Four Tools at a Glance

Here is how the four compare on plans and billing model.

Cost Breakdown by Tool

GitHub Copilot

Copilot's individual plans are Free, Pro ($10), Pro+ ($39), and Max ($100); teams pay Business ($19) or Enterprise ($39) per seat. Since June 2026 it meters premium usage through GitHub AI Credits (1 credit = $0.01, billed by tokens), while code completions and next-edit suggestions stay free and unlimited on every paid plan. That split makes Copilot the most predictable of the four for autocomplete-first developers: at $10, Pro is the cheapest paid entry point anywhere, and you only touch credits when you use agent mode, chat, or premium models.

What drives cost

• Agent mode, chat, and code review draw credits; autocomplete does not.
• Premium and larger-context models spend credits faster.
• Enterprise seats require GitHub Enterprise Cloud (~$21/user), pushing the real cost near $60.

Cursor

Cursor's tiers are Hobby (free), Pro ($20), Pro+ ($60), and Ultra ($200), with Teams at $40 (Standard) or $120 (Premium) per seat. Since mid-2025 it bills on a usage-based credit pool equal to your plan price, Pro includes about $20 of model usage. The crucial detail, and Cursor's biggest cost lever, is that Auto mode, its built-in model router, is effectively unlimited and does not draw from the pool; you only consume credits when you manually pin a premium model like Claude Opus or a GPT-5-class model. Lean on Auto and Pro rarely runs out; pin frontier models for every edit and even Ultra's larger pool drains. Our Cursor pricing 2026 guide goes deeper.

What drives cost

• Manually pinning premium models; Auto mode is unlimited and free of the pool.
• Agent usage, Max Mode, and large context windows consume more.
• Pro+ and Ultra add pool size, not features, so upgrade only when credits run out.

Claude Code

Claude Code is included on Claude Pro ($20) and Max ($100 for 5x usage, $200 for 20x), or runs on the Anthropic API per token. On subscriptions it does not have its own price; it draws from your Claude usage, a rolling 5-hour window plus a weekly cap, and that pool is shared across Claude.ai chat and the desktop and mobile apps. So a heavy Claude Code session reduces your chat capacity and vice versa. Anthropic doubled Claude Code's 5-hour limits in May 2026, widening the shared pool. For programmatic use, it bills at Claude's token rates. See Anthropic vs OpenAI for the model context.

What drives cost

• Model choice: Opus-class work spends the shared budget faster than Sonnet or Haiku.
• The pool is shared with all Claude surfaces, so coding and chat compete.
• API use bills per token (Haiku $1/$5, Sonnet 5 $2/$10, Opus 4.8 $5/$25 per million).

OpenAI Codex

Codex is bundled into ChatGPT plans: Free, Go ($8), Plus ($20), Pro ($100 for 5x usage or $200 for 20x), and Business ($25/user). It runs on GPT-5.6, with a cheaper dedicated GPT-5.3-Codex model, and since April 2026 meters usage as token-based credits on a 5-hour window plus a weekly cap. Because it shares the ChatGPT subscription, Codex is close to free if you already pay for ChatGPT, which is much of its appeal. For programmatic use it bills at OpenAI's API rates. Our OpenAI Codex cost and savings guide covers it in depth.

What drives cost

• Included with ChatGPT plans, so no separate coding subscription if you already subscribe.
• Frontier GPT-5.6 spends the allowance faster than the cheaper Codex model.
• Autonomous cloud tasks and long agent runs consume more of the window.

Which Is Cheapest for You?

There is no single cheapest tool, only the cheapest fit for a workflow:

• Autocomplete-first, cost-sensitive: GitHub Copilot Pro at $10 is the cheapest paid plan and keeps completions unlimited and free.
• All-round daily coding at $20: Cursor Pro (lean on Auto mode), Claude Pro (for Claude Code), or ChatGPT Plus (for Codex) are close; pick on the model and editor you prefer.
• Already paying for ChatGPT: Codex is nearly free to add, the best value if you live in the OpenAI ecosystem.
• Heavy agent power users: the $100 to $200 tiers (Copilot Max, Cursor Ultra, Claude Max, Codex Pro) all exist for this; choose the model you trust on your codebase.
• Teams: Copilot Business at $19 per seat is the cheapest entry; Cursor Standard is $40, Codex Business $25, and Claude Team is per seat.

The Cost Lever They All Share: Model Choice

Whichever tool you pick, the same variable dominates the bill: which model runs each task. A frontier model on a routine edit is the fastest way to drain any of these pools, and a cheaper model or an auto-router on the same edit is the fastest way to preserve it. That is why Cursor's unlimited Auto mode, Copilot's free completions, and Claude's and Codex's lighter models all matter more than the sticker price. The discipline of routing work to the cheapest model that clears the bar is exactly what our LLM cost optimization and token economics and TokenOps guides teach, and it applies to coding tools as directly as to any API.

The Verdict

The interesting thing about comparing these four on price is how quickly price stops being the answer. Their entry tiers cluster at $10 to $20, their power tiers cluster at $100 to $200, and all four now meter the expensive part the same way. The sticker price tells you almost nothing about what you will actually pay, because that is decided by how you use the tool, how much you lean on agents, and above all which models you point at your work.

So do not shop these on the plan grid. Pick the tool whose editor and model you are most productive in, then be disciplined about model choice inside it, use the free or auto tiers for routine work and save frontier models for the problems that need them. Do that, and any of the four stays cheap. Ignore it, and all four will happily meter you into a bill that has nothing to do with the plan you thought you bought.
