AI Providers

Zuplo's AI Gateway supports integration with various AI providers, allowing you to leverage different models and services for your apps.

Supported Providers

Zuplo currently supports the following AI providers:

• OpenAI
• Anthropic
• Google
• Mistral
• xAI (Grok)
• Bedrock Mantle—Amazon Bedrock's compatible-APIs endpoint, serving both OpenAI-compatible and Claude models
• Zuplo Demo—a free, keyless provider for trying the gateway
• OpenAI-compatible Custom Providers (such as Qwen, Kimi, etc)

The following capabilities are supported across providers:

Provider	Chat Completions	Embeddings	Responses	Messages
OpenAI	✅	✅	✅	❌
Anthropic	✅	❌	❌	✅
Google	✅	✅	❌	❌
Mistral	✅	✅	❌	❌
xAI	✅	✅	❌	❌
Bedrock Mantle	✅	✅	❌	✅
Zuplo Demo	✅	❌	❌	❌
OpenAI-compatible (Custom)	✅	✅	❌	❌

Responses is the OpenAI Responses API (/v1/responses), and Messages is the native Anthropic Messages API (/v1/messages). See the Universal API for the endpoint each capability maps to.

A custom provider must serve chat completions and embeddings under a /v1 path segment on its API URL, and you enter that URL as an origin root—without the /v1 suffix vendors usually publish. See Custom Providers for the exact contract.

Apps reference a provider's models as providerName/model—for example openai/gpt-5-mini or anthropic/claude-sonnet-4-6—where providerName is the name you give the provider configuration. See the Universal API.

Bedrock Mantle

Bedrock Mantle is Amazon Bedrock's compatible-APIs endpoint. It serves two model families from one host and one credential, so which capabilities apply depends on the model you call:

• OpenAI-compatible models (for example openai.gpt-oss-120b) serve chat completions and embeddings.
• Claude models serve the native Anthropic Messages API, and chat completions through the gateway's translation.

Mantle endpoints are regional, so the provider dialog asks for an AWS Region instead of an endpoint URL and builds https://bedrock-mantle.<region>.api.aws from it. Enter a standard region code such as us-east-1.

Zuplo Demo

Zuplo Demo is a free provider that Zuplo operates so you can try the AI Gateway without an account with an LLM provider. Add it like any other provider—see Managing Providers—but skip the API key: the dialog doesn't ask for one, because your gateway authenticates to the demo service itself.

The provider serves three demo persona models as chat completions, at no cost:

• zuplodemo/pirate
• zuplodemo/wizard
• zuplodemo/space-cowboy
