Shutterai

Shutterai (branded ShuttleAI) is an AI LLM gateway tool that gives developers a single unified API to call multiple large language models for text generation, image generation, and agent building. Instead of integrating each provider separately, teams route requests through one OpenAI-compatible endpoint that reaches models including GPT-5.2, GPT-5, Claude Opus 4.6, Claude Sonnet 4.6, Claude Haiku 4.5, and open-source GPT-OSS 20B and 120B. A "ShuttleAI Auto" dynamic router can pick a model per request, and the platform curates a smaller set of reliable models rather than exposing every option. Access is subscription-based rather than pure pay-per-token: plans set both a request-per-minute rate limit and a context-window ceiling, from Free (2 req/min, 8K context, 1,000 requests/month) up to Scale (80 req/min, 128K context). It ships API documentation, examples, and SDKs to shorten setup. Shutterai fits developers and small teams who want multi-provider model access behind one billing relationship and one integration. Note the tool is early and thinly documented publicly, and the api.shutterai.win host was unreachable at review time, so verify current models and limits on the official site before committing.

Developers and small teams use Shutterai to access multiple LLMs (GPT, Claude, open models) through one unified API with flat subscription pricing.
