Who it's for

Built for teams that already ship multi-model apps.

If you're comparing providers, watching token spend, or adding budgets and BYOK, this is the layer above your existing SDK.

NextModel turns model choice, routing, budgets, and BYOK into one visible control layer above the SDK. That gives product and platform teams a place to shortlist models, keep unit economics honest, and switch providers without reworking the app.

OpenAI migrationsKeep the SDK

Change base_url and compare providers without reworking the call shape.

Growing spendSee cost early

Budget by project, key, and team before traffic multiplies.

Provider mixChina + global

Keep domestic and global models in the same shortlist.

why nextmodel

One gateway.
More control over spend.

Keep model choice, budget rules, source comparison, and usage reporting out of application code. The API stays familiar while the decision layer becomes visible to product and platform teams.

01 · one sdk

OpenAI SDK, many model sources.

Already using OpenAI? Change base_url, keep chat completions, streaming, tools, and JSON-oriented workflows.

client = OpenAI(

02 · routing

Policies before production traffic.

Route by workload, source, budget, latency, or capability instead of scattering rules across services.

03 · billing

Spend by key, project, and team.

See which application paths drive token cost and turn model selection into an operational decision.

Quickstart

Three steps from an existing SDK to visible spend control.

StepCreate an API key

Issue a key for the project, environment, or workload you want to track.

StepChange base_url

Set the OpenAI SDK base URL to https://api.nextmodel.app/v1.

StepStart calling models

Use a model ID from the catalog, then compare cost and output quality.

Cost governance

Keep budgets, BYOK, teams, and reports visible before scale.

This is the layer product and platform teams use once model count and spend start to grow.

Usage analyticsProject + key

Understand which applications and environments are driving model spend.

Budget policyBefore rollout

Set budget expectations before product traffic multiplies request volume.

Governance workflows

  • Route workloads through one OpenAI-compatible interface.
  • Compare domestic and global providers by price and capability.
  • Use BYOK for teams with existing provider accounts.
  • Build monthly reports from usage and model pricing.

Featured models

Shortlist a few models before routing production traffic.

New benchmark

Before you enable caching, measure whether reuse is safe.

CacheSafety Bench checks safe hit rate, bad hit rate, semantic trap failures, and cost savings before teams trust a cache layer.

CacheSafety Bench helps teams compare safe hit rate, bad hit rate, semantic trap failures, and cost savings before they trust a cache layer in production.
