Two $100 tiers landed within three weeks of each other

The ChatGPT Pro plan at $100 a month is not the headline OpenAI shipped last quarter — that was the $200 Pro tier from late 2024. The new one, announced on April 9, 2026, sits in the awkward middle: between the $20 Plus and the $200 Pro, aimed squarely at people who outgrew Plus on Codex but never wanted the $200 ceiling. It maps almost line-for-line against Anthropic’s Claude Max 5x, which Anthropic added at $100 after the initial Max launch on April 9, 2025 — exactly one year to the day before OpenAI’s matching tier. For the first time both labs are pricing a “5x of base” tier at the exact same number.

I am not on either of these tiers. I currently pay for Claude Pro and ChatGPT Plus — the $20 each side of the ledger. So this is a Mode B read: I’m walking through what would push me to swap, not pretending I’ve benchmarked a quarter on each. The reason I’m writing it now and not in three months is the May 31 promo window, which is the one part of this story that is genuinely time-bound for solo operators on the fence.

What the ChatGPT Pro plan actually unlocks

OpenAI was unusually direct about who this is for. From their own announcement: this is not a generalist upgrade — it is a Codex tier with a side of GPT-5 access. The headline numbers, pulled from the OpenAI product page and the April 9 launch post:

  • 5x Codex usage versus the $20 Plus plan (permanent baseline).
  • 2x Codex on top of that, through May 31, 2026 — so during the promo window the $100 tier is effectively running 10x Plus on Codex sessions.
  • Unlimited GPT-5, Pro model access, Thinking and Instant models, and the same model suite as the $200 Pro tier.
  • The remaining $200 Pro tier sits at roughly 20x Plus — so the ChatGPT Pro plan is positioned as “half the headroom for half the price.”

The TechCrunch coverage frames it as the plan OpenAI “should have shipped a year ago.” That feels right from the outside. Plus users who run long Codex sessions have been complaining loudly about hitting weekly caps, and a $20-to-$200 jump was never going to convert any of them.

How Claude Max 5x compares on usage

Anthropic’s Max 5x at $100 is older, broader, and worded differently. From the Claude help center docs and Anthropic’s pricing page:

  • 5x the usage limits of Claude Pro ($20 base), measured on a weekly window.
  • Two parallel weekly caps — one across all models, one specifically for Sonnet — which means you can blow through the high-end model budget without losing your everyday model headroom.
  • Priority access to new models and features, including Claude Code on the terminal and Cowork for multi-step task handoff. This is the line that doesn’t have a clean ChatGPT Pro plan equivalent yet.
  • Real-world capacity, per Anthropic’s own framing: roughly 50–800 prompts a week depending on whether you’re chatting or running long agentic sessions.

The shape is different. Where ChatGPT’s $100 is a Codex-shaped tier with general-purpose models thrown in, Claude Max is a general-purpose tier with Claude Code and priority access thrown in.

ChatGPT Pro plan vs Claude Max: the five differences I’d weigh

If a solo operator asked me — and a few have, since the April announcement — these are the five places the ChatGPT Pro plan and Claude Max actually diverge, in the order I think they matter for someone running client work alone.

1. The headline workload. The new OpenAI tier is built for Codex. Claude Max is built for “I use this model all day across many tasks.” If your week is dominated by long agentic coding runs, the ChatGPT Pro plan is the cleaner answer. If your week is split across briefs, research, drafting, and a little code, Max is more honest about that mix.

2. The cap structure. Max’s split between an all-models cap and a Sonnet-only cap is genuinely useful for a freelancer — you stop rationing your Sonnet drafts because you burned Opus on one research run. The ChatGPT Pro plan publishes one number (“5x Plus”) and lets you discover the boundaries inside that. I prefer the Max framing on transparency.

3. The terminal story. Claude Code on the Max tier is currently the more mature terminal-native coding workflow, and Anthropic has shipped tooling for solo developers (subagents, hooks, MCP) that OpenAI’s Codex CLI has not matched feature-for-feature yet. If a non-trivial part of your week is “Claude Code agents inside repos,” that’s a real point against the ChatGPT Pro plan.

The ChatGPT Pro plan and Claude Max are priced identically, but they are not interchangeable products — they are two different bets on what a $100/month AI subscriber actually does for a living.

4. The promo window. Through May 31, 2026, the ChatGPT Pro plan runs at 2x its base Codex limit — effectively 10x Plus. After June 1 it settles back to 5x Plus. Anyone evaluating the upgrade right now is sampling an inflated version of the product. I’d discount that 2x bonus mentally before deciding.

5. The ecosystem stickiness. ChatGPT’s ecosystem (custom GPTs, Operator, the broader connector library) is wider in 2026, and a $100 Pro subscription stretches across all of that. Anthropic’s ecosystem is narrower but more focused — Cowork, Skills, and an API tier I trust more for client data routing. Wider versus deeper is the actual choice underneath the $100 line.

The promo window that quietly shifts the math

The piece of this story that almost no comparison post is calling out clearly: the ChatGPT Pro plan you would test in May is not the ChatGPT Pro plan you would pay for in July. Through May 31, OpenAI doubles Codex on the new tier as a launch incentive. From June 1, it’s back to baseline.

If you’re going to evaluate the ChatGPT Pro plan honestly, the cleanest way is to assume the 5x baseline, not the 10x promo, and decide on that. Anything else is buying a sale and hoping the regular price still feels worth it later. I’ve been burned by that pattern on tooling subscriptions before — the upgrade-during-promo-then-fail-to-cancel cycle is its own line item by year-end.

The Claude Max comparison stays flat. No promo, no escalator, the tier is what it is. That’s a small but real argument for evaluating Max in May and ChatGPT Pro plan in June.

Where I land for now

For me, I’m staying on ChatGPT Plus + Claude Pro through this window. My weekly hit-rate against Plus’s Codex caps is low — I’m not running long agentic coding sessions on OpenAI’s stack — and my Claude Pro usage is already shaped around Sonnet for drafts and Opus for research, which is exactly the split Max formalizes but doesn’t change.

The decision tree I’d give another freelancer in the same week: if more than two days a week look like “Codex doing real work on a real repo,” try the ChatGPT Pro plan during the promo and re-decide June 1. If your week looks like mine — long Claude drafts, Sonnet for client briefs, occasional Cursor or Claude Code spikes — Claude Max is the upgrade path that fits the workload. Either way, $100 is a real line on a freelance P&L, and the right move this week might be: neither yet.

FAQ

Is the ChatGPT Pro plan worth it for non-coders?

No, not at $100/month. The plan’s only meaningful differentiator over Plus is Codex usage, and Plus already covers GPT-5 and the standard model suite at usable caps. A non-coder upgrading from Plus to the ChatGPT Pro plan is paying 5x for 5x more of the one feature they don’t use.

Does Claude Max include Claude Code on every machine?

Yes. The Max tier includes terminal-based Claude Code access, with priority on new models and features. Solo operators who want Claude Code as a daily driver get the cleanest path through Max — Anthropic ships the IDE/terminal tooling and the model usage on the same subscription line.

Should I downgrade from $200 ChatGPT Pro to the new $100 ChatGPT Pro plan?

It depends on Codex usage. The $200 tier still offers roughly 4x more headroom than the $100 ChatGPT Pro plan. If you regularly hit Pro’s caps, the downgrade will hurt. If you’ve never come close to them, the new $100 ChatGPT Pro plan is the obvious move and the savings round-trip the difference in two months.

Does the May 31 ChatGPT Pro plan promo auto-renew at 2x?

Not yet confirmed. OpenAI’s wording in the launch post specifies the 2x bonus runs through May 31, 2026, then resets to 5x Plus. Treat it as a temporary boost, not a permanent baseline, and budget against the post-promo number.
