Choosing a Plan
A complete comparison of Free, Eco ($9/mo), Pro ($19/mo), and Ultra ($200/mo) tiers, rate limits, and credit budgets.
Transparent, Cost-Based Tiers
Most AI platforms charge arbitrary message limits (e.g., "40 messages every 3 hours"). ARMES is built differently: our plans provide generous monthly and daily cost budgets that directly reflect what underlying inference costs.
Whether you want private access without spending a dollar or complete enterprise frontier power, there is an ARMES plan designed for your workload.

Billing Cadence & Annual Savings
ARMES offers both monthly and annual billing across all paid plans. Choosing annual billing provides 2 months free (a 16.7% discount):
- Eco Annual: $90 / year (equivalent to $7.50 / month, saving $18 / year compared to monthly billing).
- Pro Annual: $190 / year (equivalent to $15.83 / month, saving $38 / year compared to the launch rate and $110 / year compared to the standard rate).
- Ultra Annual: $2,000 / year (equivalent to $166.67 / month, saving $400 / year).
Direct Subscriptions & Promotional Campaigns
ARMES subscriptions are direct, paid-upfront subscriptions with immediate access to your plan's full allowance. Subscriptions can be managed or canceled anytime via the Stripe billing portal with zero lock-in. During special marketing promotions or seasonal sprints, ARMES may offer promotional free trials on Eco and Pro plans.
Monthly Allowance Resets on Annual Plans
Annual subscribers receive a refreshed monthly compute allowance every 30 days throughout the 12-month billing period. This protects your quota and ensures sustained, predictable high-speed compute every single month.

What Happens When You Reach a Cap?
Unlike platforms that abruptly cut you off with an error screen, ARMES provides full transparency:
- Reset Timers: Your daily budget resets at midnight UTC, and your monthly budget resets with your billing cycle.
- AI Boost Credits: If you exceed your included plan cap, optional AI Credits (available in $5, $15, and $30 packs) take over automatically so your flow is never interrupted. AI Credits never expire and are only consumed when you exceed your plan allowance.
