WHY NEWTON’S

Everything you need to move from idea to request.

01

03

OPENAI-COMPATIBLE

MODELS

One interface for the models you use.

Available models appear here with their current prices. If a model is not listed, it is not ready to use through Newton’s.

CHECKING AVAILABILITY

Available models appear here first.

We list a model when its name, price, and current availability are clear. If it is not listed yet, it is not ready to use through Newton’s.

Check model availability →

Prices are based on each provider’s published billing units.
Open a model page to see the current rate before making a request.

FEATURED APPS

Builders use the same interfaces; Newton’s keeps the rail and usage boundaries.

Codex / ChatGPT

Test Newton’s experimental Responses route with a non-sensitive Codex task before changing a real workflow.

Claude Code

Use Newton’s Anthropic gateway after ANTHROPIC_BASE_URL + gateway credential verification.

SDK + tools

Keep your existing coding stack. Test each path with one request before switching flow.

Model clients

OpenAI-compatible endpoint + model IDs, then review usage in Activity.
