APIPark vs Velos (formerly GradientJ)

APIPark is an open-source LLM gateway and API developer portal for enterprises that need one place to call, govern, and bill AI models and internal APIs. It routes traffic to 200+ large language models through a single OpenAI-compatible endpoint, so teams stop wiring separate vendor SDKs for every model they add.

Where most API gateways only forward requests, APIPark also treats models and APIs as tradable assets. It bundles unified authentication, approval workflows, recharge billing, multi-level distribution, and profit reporting so platform teams can sell surplus model capacity or package business APIs without building a separate marketplace stack.

Platform engineers and AI teams use it to set per-tenant quotas, rate limits, and masking rules before production traffic hits upstream models. API managers get portals for publishing APIs, tracking usage, and approving access requests. The Community Edition covers core gateway and portal features; the Enterprise Edition adds advanced governance, runtime statistics, and premium support.

Velos is a managed automation platform for back-office teams that want to replace outsourced manual work with software. It targets insurance carriers, MGAs, and finance operations that still rely on BPOs or internal staff for document-heavy workflows like bordereaux, policy servicing, and month-end close.

The company learns your process rules, tests against your real data, and turns recurring work into auditable workflows that combine code with large language models. Velos handles design, deployment, and ongoing management so teams get faster turnaround without adding headcount every time volume spikes.

It is built for organizations handling sensitive, high-volume operations where accuracy matters. Customers include commercial insurance teams, private equity firms, and fractional CFO shops looking to automate multi-hour processes that used to require offshore teams or manual spreadsheets.
