Claude's $200 Plan Carries About 5× the Seat Value of ChatGPT Pro 200. Which Allowance Lines Go on the Order Form?

Two $200 seats. One carries about five times the work. Most order forms treat them as the same line.

SemiAnalysis limit-tested every major AI subscription and published the results on Oct 5 2026 (SemiAnalysis). If you buy AI seats for a revenue team, read this before your next renewal. The allowance you buy today will not hold still.

What SemiAnalysis measured

They ran experiments that isolate one token type at a time (input, cache write, cache read, output), watched how far each plan's usage meter moved, and converted that to API-equivalent dollars for an agentic workload based on their own September usage (SemiAnalysis). Their example: use 1% of a $200 plan's monthly limit and you used $2 of value.

Their rule for reading any plan: value only makes sense as the full (plan, model, workload) tuple. One plan can be worth very different amounts depending on which model your team runs and how.

The gap

• Daily driver: about 5×. On Claude Opus 5.5 vs GPT-6.1 Sol, the mid-tier models both labs market as the daily driver, Anthropic's $200 plan offers ~5× the API-equivalent value of OpenAI's $200 plan "across the board" (SemiAnalysis). Sol is cheaper per token, and the gap still holds on raw token counts.
• Top tier: close. OpenAI's $200 plan is used up after $2,897 of GPT-6 Astra. Anthropic's $200 plan still has 50% left after $2,485 of Fable 5.1, because Fable can only use half the limit (SemiAnalysis).
• Per dollar: after last week's cut, OpenAI's Pro 100, 200, and 500 give the same tokens per dollar on every model. Anthropic already gave every tier the same per-dollar value (SemiAnalysis).

What moved last week

• OpenAI halved its $200 plan. SemiAnalysis tracking confirmed a ~50% cut in API-equivalent value and a new $500 tier. The $500 plan gives 21% more Astra than the old $200 plan (SemiAnalysis).
• Grandfather window. Pro 200 subscribers active any time from Sep 22 through 10 a.m. PT Sep 29 2026 keep the previous allowance through Oct 29 2026, then move to the lower allowance at the same $200 (OpenAI Help).
• Sol price cut, flat limits. GPT-6.1 Sol cut cache reads 50%, and OpenAI left Sol token limits on the $200 plan unchanged. API-equivalent value fell ~30% (SemiAnalysis).
• Anthropic raised Opus limits. With the Opus 5.5 price cut (input and output -20%, cache reads -60% vs Opus 5), Anthropic raised Opus token limits ~20% on Max and ~50% on Pro. SemiAnalysis says that did not fully offset the API price cut (SemiAnalysis).

The cut mechanics are covered in Pro 200 usage cut and Pro 500 Ultrafast. This piece is about what each seat is worth after the dust settles.

Heavy users run the vendor at a loss

SemiAnalysis models a Claude plan at 92% API gross margin. A user who maxes out Opus 5.5 runs it at -369% gross margin. At a more realistic 20% utilization it is about 6%. The same math on Fable 5.1 gives 1% maxed and 80% at 20% (SemiAnalysis).

Subscriptions are about 10% of Anthropic revenue but can take over 40% of its inference compute, lowering blended revenue per megawatt by ~$36M, per SemiAnalysis estimates (SemiAnalysis).

Your heaviest agent users are the vendor's most expensive customers. That is where allowances get trimmed next. SemiAnalysis also caught one provider running an “extremely tiny” A/B test with ~20% lower limits on one of three identical accounts. Limits can change without an announcement.

Order Form checklist

1. Workload profile. Pull model mix and token shape (input, cache, output) per user for two to four weeks before you buy seats.
2. Price on allowance. Convert each plan to API-equivalent value on your workload. Two $200 seats can sit about 5× apart.
3. Allowance floor. Minimum included usage per model, per plan, written on the form.
4. Change notice. Days of written notice before limits or credit costs drop, with a credit or exit if they do.
5. Grandfather term. How long the current allowance holds after a cut. OpenAI's runs through Oct 29.
6. Premium-model cap. The share of the plan the top model can use. Fable 5.1 stops at 50%.
7. Heavy-user route. Agent and automation users who max the seat move to metered API with a commitment. Commitment terms: Anthropic commitment cliff vs OpenAI grace.
8. Monthly re-test. Run a light meter check or get usage data from the vendor every month.

Keep the meters apart

• Seat allowance (this piece): what a $200 subscription carries, per model and workload.
• Pro 200 cut and Pro 500: the DevDay decoder.
• API serving tiers: Astra Ultrafast at 6× Standard list is a per-token API line. See Astra Ultrafast at 6×.
• API commitments: Anthropic commitment cliff vs OpenAI grace.

Soft opens

• All SemiAnalysis figures are modeled estimates from its limit tests. Full tables sit in its paid Tokenomics Model. Confirm on your own account.
• SemiAnalysis uses ~5× in the head-to-head and ~4× in a later note on OpenAI's lack of a five-hour limit. We use about 5× from the head-to-head.
• Dollar values for Opus 5.5 and Sol are not in the public section. We use the ratio only.
• The comparison covers individual plans. Team and Enterprise seat allowances can differ. Get yours in writing.
