OpenAI launched a $100/month ChatGPT Pro tier yesterday. It is not subtle about who they are going after. TechCrunch quoted an OpenAI spokesperson directly: the new tier "delivers more coding capacity per dollar across paid tiers" compared to Claude Code. That is a direct shot at Anthropic.
So now you have two $100/month AI subscriptions fighting for the same developer wallet. Claude Max 5x has been at $100 since late 2024. OpenAI just matched it, priced identically, aimed at the same audience. Meanwhile Cursor Pro sits at $20 and does something different enough to deserve its own spot in this comparison.
If you are a solo developer or indie hacker trying to figure out where your subscription budget goes this month, here is the honest breakdown.
Quick verdict
| Tool | Price | Best for | Coding agent | Rating |
|---|---|---|---|---|
| ChatGPT Pro $100 | $100/month | Heavy Codex users switching from Claude | Codex (cloud + local) | ⭐⭐⭐⭐ |
| Claude Max 5x | $100/month | Developers already in the Claude ecosystem | Claude Code | ⭐⭐⭐⭐⭐ |
| Cursor Pro | $20/month | Daily IDE users who want AI inside their editor | Agent mode (in-editor) | ⭐⭐⭐⭐ |
If you are starting from scratch and want the most capable standalone AI coding agent, Claude Max still wins. If you are already deep in the OpenAI ecosystem or have been hitting Claude's usage limits, the new ChatGPT Pro tier is worth a real look. Cursor is a different product entirely and the right choice if you want AI inside your editor rather than running tasks in a terminal.
ChatGPT Pro $100: what you actually get
OpenAI's full plan lineup now looks like this: Free (with ads), Go ($8/month, with ads), Plus ($20/month), Pro $100 (new), Pro $200 (still exists, quietly).
The $100 tier gives you:
- 5x more Codex usage than the $20 Plus plan
- All Pro features including GPT-5.4 Pro model access
- Unlimited access to Instant and Thinking models
- Codex running both locally on your machine and as cloud tasks
- Bonus through May 31: 10x Codex usage instead of 5x during the launch promotion
Codex is OpenAI's agentic coding tool. It handles multi-file edits, runs shell commands, writes and executes tests, and works on tasks in the background while you do other things. Think of it as OpenAI's answer to Claude Code.
The naming is a mess. There are now two ChatGPT Pro plans, both called "Pro." The $100 one is for 5x usage, the $200 one is for 20x. OpenAI published an explainer about their own naming, which tells you everything about how clearly this was thought through.
The real reason this exists: Anthropic's Claude Code has been dominant in the agentic coding space. Anthropic's ARR reportedly topped $30 billion, driven largely by Claude Code adoption. OpenAI needed a competitive $100 tier. The timing is not a coincidence.
Who should use it: Developers who have been using ChatGPT Plus and hitting Codex limits regularly. Also worth considering if you were using Claude Code through a third-party harness that Anthropic restricted in early April and you are looking to switch.
The honest con: Codex is good but Claude Code has had a meaningful head start in the agentic coding market. The ecosystem, documentation, and community of tips around Claude Code is more mature. OpenAI's 10x launch promo through May 31 is designed to get you hooked before the limits drop back to 5x. Be aware of that before you cancel anything.
Claude Max 5x: the incumbent
Anthropic launched the Max plan in late 2024. At $100/month, Max 5x gives you:
- 5x the usage of Claude Pro ($20/month)
- Claude Code in the terminal, web, and desktop
- Full Opus 4.6 access (1 million token context window, agent teams)
- Persistent memory across conversations
- Priority access during peak hours
- Early access to new features
Claude Code is Anthropic's terminal-native coding agent. It reads your full project, plans changes across files, executes shell commands, handles multi-file refactors, and can run autonomous sessions. If you have used it for more than a few hours on a real project, you know why 3 million people a week use Codex and more are on Claude Code. They are genuinely different from autocomplete tools.
The Max 20x plan at $200/month takes limits off the table entirely for most developers. At that level, full-day coding sessions, parallel agent tasks, and heavy Opus 4.6 usage stop being a concern.
One developer tracked their usage over 8 months and found the Max plan saved over 93% compared to equivalent API costs. At heavy usage levels, the math strongly favors the subscription.
Who should use it: Developers who use AI coding tools as their primary development workflow and hit Pro rate limits more than twice a week. If you are building SaaS products solo and Claude Code is your main tool, Max 5x is the right call.
The honest con: Anthropic made a controversial move in early April blocking Claude subscriptions from powering third-party agentic harnesses. If you were relying on something like OpenClaw to extend Claude's functionality, that access is now restricted. This is part of why OpenAI's $100 tier is landing on fertile ground right now.
Cursor Pro: a different question entirely
Cursor is not a standalone coding agent. It is an AI-powered IDE built on VS Code. That distinction matters.
Cursor Pro at $20/month gives you:
- $20 monthly credit pool for frontier model access (Claude Sonnet, GPT-5.4, Gemini)
- Agent mode for multi-file edits inside the editor
- Auto mode (effectively unlimited, uses lower-cost models automatically)
- Background agents that run tasks while you work on something else
- Full codebase context awareness
The credit system confused a lot of people when Cursor introduced it in mid-2025. The short version: if you stick to Auto mode, Pro is effectively unlimited for most use cases. Credits only deplete when you manually select expensive frontier models on heavy tasks. Most developers never exhaust their monthly pool.
Cursor Pro+ at $60/month triples your credit pool. Ultra at $200/month gives you $400 in credits.
Who should use it: Developers who want AI integrated directly into their editor experience. Cursor is better than Claude Code if you want to stay in an IDE, use multiple AI models interchangeably, and prefer in-context editing over terminal-based agents. It is also the right answer if $20/month is your actual budget.
The honest con: Cursor requires you to abandon your current editor. If you are on JetBrains, real Vim, or anything that is not VS Code-based, the switch cost is real. The credit system also caused genuine billing surprises when it launched. Turn on spend limits before you start using frontier models manually.
Head-to-head: the dimensions that actually matter
Coding agent capability: Claude Code and Codex are both serious agentic tools. Claude Code has been in the market longer, has more community resources, and handles complex multi-file refactors well. Codex is newer as a standalone product but OpenAI has invested heavily. Cursor's agent mode is capable but lives inside an editor rather than running fully autonomously.
Usage limits at $100: Both Claude Max 5x and ChatGPT Pro $100 offer 5x their base plan. The difference is what the base plan actually allows. OpenAI is "rebalancing" Plus limits as part of this launch, which effectively means Plus users get slightly less so the $100 tier looks more valuable. Through May 31, ChatGPT Pro $100 users get 10x, but that is temporary.
Model access: Claude Max 5x includes Opus 4.6, which is Anthropic's best model. ChatGPT Pro $100 includes GPT-5.4 Pro. Both are flagship-tier models at this price point.
Price: ChatGPT Pro $100 and Claude Max 5x are identical at $100/month. Cursor Pro is $20. The question is whether you need a standalone coding agent ($100 tier tools) or IDE-integrated AI ($20 with Cursor).
The competitive context: OpenAI explicitly launched this tier to compete with Anthropic. One person emailed Tibo at Codex saying they would cancel their Claude Max plan the moment a $100 Codex option launched. They did. That is the audience OpenAI is targeting. If you are loyal to neither ecosystem, the honest advice is to trial both and see which agent works better on your actual codebase.
Which one should you use?
Use ChatGPT Pro $100 if: You are currently on ChatGPT Plus and hitting Codex limits, you have recently switched away from Claude due to the third-party harness restrictions, or you want to try Codex during the 10x promo period (through May 31) before committing.
Use Claude Max 5x if: Claude Code is already your primary development tool and you hit Pro rate limits regularly. The ecosystem is more mature, the community is larger, and Opus 4.6 is genuinely excellent at complex multi-file work. Do not switch because of one frustrating rate limit day.
Use Cursor Pro if: You want AI deeply integrated into your editor rather than running in a terminal. $20/month is a real number for your budget. You prefer switching between Claude, GPT, and Gemini models depending on the task. Or you primarily need autocomplete and in-editor chat rather than long autonomous coding sessions.
Do not subscribe to two $100 tools. The temptation to stack Claude Max and ChatGPT Pro is real, especially during the Codex promo. That is $200/month on two tools that largely overlap. Pick one agent, stick with it for a month, and see where you hit friction.
FAQ
Is ChatGPT Pro $100 the same as the old Pro $200?
No. There are now two ChatGPT Pro plans. The new $100 tier gives you 5x Codex usage vs Plus. The $200 tier still exists and gives you 20x. OpenAI buried the $200 plan in their pricing page but confirmed it still works.
Does Claude Max include Claude Code?
Yes. Claude Code is included in Claude Pro ($20), Claude Max 5x ($100), and Claude Max 20x ($200). The difference between tiers is how much you can use it before hitting rate limits.
Is Cursor a replacement for Claude Code or Codex?
Not really. Cursor is an IDE with AI built in. Claude Code and Codex are standalone agents that work outside your editor. Many developers use Cursor for in-editor work and Claude Code for autonomous background tasks. They are complementary more than competitive.
Which has better limits, ChatGPT Pro $100 or Claude Max 5x?
Both offer 5x their base plan. The actual token counts vary by model and task type. Through May 31, ChatGPT Pro $100 temporarily offers 10x, but that promotional limit goes away.
Can I use my own API key with Cursor to avoid credit limits?
Yes. Cursor supports bring-your-own-API-key for OpenAI, Anthropic, and other providers. This bypasses Cursor's credit system entirely and you pay the model provider directly. Worth doing if you already have API access through your company.
Bottom line
OpenAI's $100 tier is a real product aimed at a real problem. The timing is strategic and the competition is good for developers. Both companies are now accountable to a clear price point.
If you are happy with Claude Code and not hitting limits constantly, stay on Max. Nothing in the Codex launch changes the quality of what you are already using. If you have been frustrated with Claude's recent restrictions or want to try Codex during the generous promo period, the $100 ChatGPT Pro tier is worth a month's trial.
For most solo developers on a realistic budget, Cursor Pro at $20 and Claude Pro at $20 together still costs less than one $100 tier subscription and covers most coding needs. The $100 tier is for developers who have outgrown that setup and need more.
