A small, real trial wallet for testing Gate 15 before you commit.
A paid account for builders who want model charges on their own provider accounts.
A predictable monthly wallet for regular building, with immediate correction follow-ups kept separate.
A larger model wallet you can size to the work ahead, with a clear edge on Gate 15-funded usage.

Free includes a one-time $3 build balance so you can run real tasks and test the workflow without entering a card. When it reaches $0, model-funded work stops until you choose a paid plan.
BYOK is $8 per month for provider-key access, with no Gate 15 model wallet. Anthropic is required for every session because it powers internal planning, compaction, and Auto. Add OpenAI, Google, or Z.ai for any manual models you use. Gate 15 never falls back to its own keys on this plan.
It is a separate allowance for an immediate follow-up when completed work comes back broken and you ask Gate 15 to retry or correct it. It is not another general-purpose wallet, so ordinary building cannot quietly consume that reserve.
Choose $100–$200 per month in $10 steps. Build balance is 85% of the commitment minus $10; the retry/correction reserve is 10%. That gives $85 total model credits at $100 and $180 at $200, with the exact split shown before checkout.
Yes. On Plus and Max, a configured provider key overrides the Gate 15 wallet for that provider. Leave it blank to use included credits. Keys are encrypted, write-only, and never exposed to the sandbox or agent.
Stripe hosts checkout and the billing portal. Gate 15 stores the plan and credit-ledger state needed to enforce your wallet, but card details stay with Stripe.
Your guest projects carry over to the full account automatically. Subscriptions require a full account so purchases, credits, and receipts stay attached to the right person.
Start with $3 in trial usage. BYOK from $8/month. Included model credits from $20/month.
