CU are managed work units
Use CU when you want Meridian to handle managed routing, optimization, compression, and execution strategy for heavier work.
Meridian Credits
Credit Units fund Meridian-managed execution.
Use CUs when you want Meridian to carry more of the routing, optimization, and managed model execution workload.
Choose the subscription that fits your workflow, then add credits when you need more managed throughput.
Your plan controls access
Each plan unlocks a managed execution range. Choose the subscription first, then add CU when the workload grows.
BYOK is separate
Keep provider billing under your own keys when direct control matters. Use CU when Meridian-managed execution is the better fit.
Turn any AI request into plans, artifacts, audits, and finished work
Ari is the guided experience; Meridian is the execution system underneath it
Route phases across frontier, fast, local, and visual model types with multi-vendor support

Core Model
Use credits for managed execution.
Credit Units support Meridian-managed routing, model use, compression, retrieval, and execution work.
Bring your own keys (BYOK) when you want direct provider billing
BYOK lets Meridian run through your own model accounts so you keep direct provider billing and account-level visibility.
- Change to BYOK at any time.
- Best for buyers who want direct vendor billing and provider-level visibility
- Available in every tier, including Free
- Useful as fallback when managed CU inventory is low - you can use both at the same time
Use Meridian-managed execution when you want a easier path
CUs use Meridian-managed keys so Meridian can optimize the execution path for better workflow density, cleaner handoffs, and less operational friction.
- Credit Units (CUs) are units of work, not raw token buckets
- Built to produce more usable work per spend than simple pass-through usage
- Ideal when you want less setup friction and faster starts - default setting
Blend managed CUs and BYOK when you want flexibility
Hybrid mode lets Meridian use CUs first while keeping your own keys available when you want direct-provider access or a clean fallback path. This means if run out of CUs, you can still run the request with your own keys with no downtime.
- CUs-first keeps the easiest path in front of the you or your team
- You or your team can still prefer your own keys when you want BYOK priority
- Useful for teams that want resilience without forcing one billing model
Eligibility
Credit access by plan
Each plan opens a different managed execution range, from guided preview through governed volume.
Free guided preview access
Free starts with a guided managed preview built to deliver a fast, tangible first win. After that, Free can extend the experience with Starter and Small CU blocks.
- Guided preview after signup, then Starter and Small CU only.
- Preview-focused managed execution with lower-cost models, tighter routing limits, lighter artifacts, and shallow optimization depth.
Builder managed execution access
Builder turns the guided preview into real repeatable delivery. It keeps BYOK available, reduces setup friction, and opens Starter, Small, and Medium CU blocks.
- Starter, Small, and Medium CU blocks. Founding Builder Preview annual includes one-time Small Block through September 30, 2026. Large and above require Pro+.
- Stronger routing, richer artifacts, more continuation room, and better model flexibility than Free without opening the full Pro+ plan.
Pro+ full individual CU access
Pro+ is where Meridian-managed execution becomes a primary workflow choice, with deeper research, richer artifacts, guided builds, and the strongest individual Founding offer.
- Monthly Founding Builder Preview includes one-time Starter Block. Annual Founding Builder Preview includes one-time Medium Block plus Small Block on annual renewal through September 30, 2026, then the full individual CU range through 3XL.
- Full individual managed-execution profile with deeper compression, broader routing, stronger previews, and richer artifact support.
Team pooled CU inventory
Teams buy pooled managed throughput for shared execution, faster coordination, manager visibility, and parallel delivery across the group.
- Access to pooled team CU with a 2-seat minimum. Founding Team Preview annual includes 1,000 pooled CU per seat, capped at 5,000 pooled CU, on activation and annual renewal through September 30, 2026.
- Shared managed routing, team coordination controls, and pooled operational inventory.
Business pooled corporate CU inventory
Business adds corporate auth, stronger security controls, and a serious shared operating model for companies that want annual purchasing without full enterprise procurement.
- Access to pooled team CU with a 5-seat annual minimum. Founding Partner Preview annual includes 5,000 pooled CU through September 30, 2026.
- Shared managed routing with corporate auth, security controls, policy oversight, and pooled operational inventory.
