Setting a usage limit
Last updated: October 10, 2025
At together.ai we understand that everyone has their own circumstances and we want to make sure that none of our customers are ever put in a tricky situation as a result of an unexpected bill from us.
To try and avoid such a situation, we offer usage based billing and credit packs, which are charged at the time of purchase.
Important: Credits purchased after an invoice is generated cannot be used to clear previous invoices or past due balances. Past due balances must be paid separately using a valid payment method, regardless of your available credit balance.
If you don't want to use credit packs, or want to make sure you don't spend any more than you buy in credits you can set a balance limit in your accounts billing settings. Build Tiers 1-4 have a fixed $100 limit. Build Tier 5, Scale and Enterprise limits can be higher:
Important payment method requirements: When purchasing credit packs or setting up billing, Together.ai only accepts credit or debit cards that are directly tied to a bank account. Pre-paid cards of any kind are not supported by the payment system. If you experience issues with card authorization or declined payments, verify that you're using a standard credit or debit card rather than a pre-paid card.
If you're experiencing access issues with a positive balance, check whether your credits are free credits or purchased credits and verify your account tier in your billing settings.
Important Note About Build Tier Access Restrictions
Even with a positive balance and no usage limit set, you may still encounter access restrictions due to Build Tier requirements. Build tiers are determined by actual account spend (purchased credits or platform usage), not free credits.
Key points to remember:
Free credits don't count toward tier upgrades
Build Tier 1 requires $5 of actual account spend
Build Tier 2 requires $50 of actual account spend
Some premium models (including Flux Pro 1.1, Flux Pro 1, and other high-end models) are restricted to Build Tier 2 or higher
Access restrictions apply regardless of your credit balance or usage limit settings
Common scenarios:
If you're seeing "Free tier" access errors despite having credits, you may need to purchase credits to upgrade to Build Tier 1
If you encounter "tier access" errors for premium models, you may need Build Tier 2 status ($50 total spend)
If you're experiencing access issues with a positive balance, check whether your credits are free credits or purchased credits and verify your account tier in your billing settings.
Keep in mind that once the limit is hit and enforced, any usage of together.ai services will be blocked until you increase the limit or buy a credit pack.
