# Alpha 1.6.3 — NEXUS
> Deep release guide to Starfire AI Alpha 1.6.3 NEXUS: frontend, identity, Organizations 3.0, Billing 4.0, automation, Control Center 4.0, and Developer Platform expansion.
# Alpha 1.6.3 — NEXUS
**Alpha 1.6.3 — NEXUS** is the Starfire AI release line focused on turning the FORGE-era platform foundations into a more unified product: deeper identity, Organizations 3.0, Billing 4.0, expanded automation, a much larger Control Center, and a redesigned NEXUS frontend.
Rather than treating the web app, backend, billing, organizations, and administration as separate projects, NEXUS moves them toward one coherent operating model.
## Major release areas
### NEXUS frontend
The frontend overhaul expands Starfire beyond a chat-centric layout into a broader workspace for:
* NEXUS Home
* Chat & Models
* Projects
* Knowledge
* repositories
* FORGE
* Developer Platform
* Billing
* Organizations
* Agents
* Tasks and Workflows
* Schedules and Watchers
* Approvals
* Memory
* Control Center
The redesign also includes continuing responsive/mobile and navigation work.
### People & Identity 4.0
NEXUS expands the identity system from sign-in/profile fundamentals into deeper account operations:
* richer user detail
* account state
* sessions and devices
* security events
* organization membership context
* usage and credits
* feature/model overrides
* administrative access controls
The platform keeps personal identity separate from organization roles and platform-admin RBAC.
### Organizations 3.0
Organizations become a deeper ownership and policy boundary with work around:
* membership and invitations
* roles and permissions
* seats
* organization billing
* shared credits and usage
* projects and Knowledge
* policy controls
* developer ownership
The goal is for business resources to belong to the organization instead of depending on one employee's personal account.
### Billing 4.0
Billing 4.0 strengthens the entire subscription lifecycle:
* `BillingAccount` as the Starfire billing context
* Stripe customer linkage before checkout
* deterministic price-to-plan mappings
* idempotent webhook processing
* transactional provisioning
* organization billing and credits
* reconciliation and polling
* Stripe customer portal integration
* in-place plan and seat changes
* deeper Control Center billing diagnostics
The key principle is that Stripe payment state and Starfire entitlements should reconcile into one coherent account state.
### Agents, workflows, approvals & memory
NEXUS broadens Starfire's agent model toward structured automation:
* custom agents
* tasks
* workflows
* schedules
* watchers
* approval gates
* persistent memory concepts
* runtime budgets and limits
These systems can be staged independently from basic custom-agent chat behavior.
### Control Center 4.0
Control Center becomes a much deeper platform operating surface spanning:
* Users & Identity
* Organizations
* Models and Providers
* Routing and Fallbacks
* Intelligence workloads
* Developer Platform
* Billing
* Security & Audit
* Configuration
* System Health
* Incidents
The release moves normal administration away from direct database edits and source/config-file changes where dynamic administration is appropriate.
### Developer Platform expansion
NEXUS continues the v1 Developer Platform foundation around:
* versioned API resources
* API keys and scoped access
* applications and service accounts
* Responses and Runs
* Research APIs
* FORGE Build APIs
* Files and Artifacts
* Knowledge and Embeddings
* webhooks and delivery history
* logs and usage
* OpenAPI/SDK direction
The docs intentionally distinguish the designed Alpha contract from endpoints that are broadly enabled in a particular deployment.

## Stability and platform work
The 1.6.3 line also includes ongoing fixes and hardening around frontend hydration, mobile navigation/performance, plan switching, billing attachment/reconciliation, administrative workflows, and backend subsystem integration.
## Availability
Alpha 1.6.3 is a release line, not a promise that every listed capability is enabled for every account at the same moment. Features can depend on deployment state, migration state, plan, organization policy, feature flags, administrator rollout, and provider health.
