Why HAI Gateway?
Six core advantages — simpler, more stable, and more cost-effective AI API calls.
01 · Unified Access
One Account, All Models
No more juggling multi-platform accounts. One HAI account accesses every leading model — zero ban anxiety. Switch models with a single parameter change, zero migration cost.
02 · Instant Sync
Instant Official Sync
Instantly syncs with the latest global model releases, priced exactly to official rates. New models available on day one — always on the AI frontier.
03 · Precise Billing
Crystal-Clear Billing
Pay per token, clear unit pricing, costs fully under control. Multiplier × official rate = your actual cost. No monthly fees, no minimums, no hidden charges. Top up and go.
04 · Observability
Visual Dashboard
Real-time dashboard with usage and spending details at a glance. Unified stats across models and API Keys, balance alerts pushed in real time — every penny fully accounted for.
Service Tiers
More top-ups, better rates
Your account automatically upgrades with cumulative top-ups. Multipliers vary by provider and channel — token-based billing keeps costs under control.
* Some models may not follow the discount tiers due to temporary compute constraints. Please refer to the HAI Gateway platform for the latest pricing.
Multipliers are applied to each provider’s official list price. Actual billing follows the tier active on the top-up date.
