Rent up 150%.
Compute cut in half.
Same seat. New terms.
At OpenAI DevDay 2026 (Business Insider, Sept. 29), the $200/month Pro plan reopened with half the compute allowance — GPT-6 Pro chat messages cut from 200 to 100 per week — while the new $500/month Pro 500 tier takes its place at the top of the price ladder. One product announcement, two directions of squeeze, one direction of dependency.
Your costs go up. Your capacity goes down. Their pricing.
The price ladder has no ceiling
Prior top plan: $200/month. New top plan: $500/month — a 150% step for the same desk. Nothing in the architecture prevents a third tier; the only constraint is how many re-pricings your budget survives.
Allowances are rationed by discretion, not contract
GPT-6 Pro chat dropped from 200 to 100 messages per week. The $200 plan's compute allowance fell from 20x Plus to 10x. No outage, no negotiation: the allotment you built your workflow on simply got smaller in a product update.
Your roadmap is their pricing page
When capacity, rate limits, and tiers are all decided server-side by one vendor, your five-year cost model is a guess. Sovereign local compute is the only line item that stays fixed while their prices move.
Subscription rent compounds. Hardware depreciates once, then works.
A written AI-use policy is one forgetful user away from the same failure. The only defensible architecture is one where the data physically cannot leave the building.
// The cloud-AI exposure
- + Top tier $500/mo/seat and climbing — no contractual ceiling
- + Allotments shrink at platform discretion (20x to 10x; 200 to 100 msg/week)
- + Per-seat rent never capitalizes: nothing on the balance sheet
- + Pricing power is 100% on their side of the API
// The Aradia posture
- + Zero egress — air-gapped default, zero open inbound ports
- + Capacity is owned, not rented: fixed CapEx, $0 per token forever
- + Frozen model versions: audited, reproducible, defensible
- + One CapEx line item, depreciable under IRS Section 179

? YOU BUILT WORKFLOWS ON AN ALLOTMENT
Any workflow sized to 'the current plan' is sized to a number that already moved once this year. When the allowance shrinks, the workflow does not get slower — it gets interrupted.
? YOUR COST MODEL IS AN ESTIMATE OF THEIR MOOD
If the answer to 'what will AI compute cost us in 24 months' depends on what a single vendor announces next quarter, you do not have a cost model. You have an exposure.
? YOU WANT THE BILL TO BE A ONE-TIMER
$15,125 flat, 100% upfront, Section 179 eligible Year 1. 1–5 concurrent users or agents, 128 GB coherent memory, $0 per token forever. Twelve months of a $500/mo/seat subscription is roughly the machine.
