Compare 700+ AI models on one gateway

The Opper model directory lists every large language model on the gateway, with image, video, and voice models alongside them, and the decision models that answer typed questions instead of writing text. Filter by price, context window, capability, benchmark score, hosting region, and zero data retention, then run any of them through one OpenAI-compatible API and a single key. The default order leads with the models Artificial Analysis ranks highest on its intelligence index, which you can see in full on the LLM leaderboard. Put two models head to head on the comparison pages, or read how routing and fallbacks work on the LLM gateway.

Frequently asked questions

How do you compare AI models on Opper?

+
Every model on the gateway is listed with its price per million tokens, context window, capabilities, benchmark scores, hosting region, and zero-data-retention posture, so you can sort and filter to the right model, then switch between them through one OpenAI-compatible API and a single key. Compare models side by side

What is the cheapest LLM for my use case?

+
Sort the directory by input or output price to find the lowest cost per million tokens, from small budget models for high-volume work to frontier models for hard reasoning. Because every model runs through one gateway, you can route cheap models for easy calls and keep frontier models for the few that need them. See gateway pricing

How do I choose an LLM router?

+
An LLM router sends each request to the best model and falls back automatically when one is slow or unavailable. Opper routes across 700+ models behind a single API key, with built-in observability and European hosting, so you can change models without touching client code. How the LLM gateway works

Which AI models are hosted in the EU with zero data retention?

+
Filter the directory by European residency and zero data retention to see every model on a route where prompts and outputs are not used for training and not kept for anything beyond abuse monitoring. The ZDR chip includes routes with abuse monitoring; untick "Abuse monitoring only" in the Data retention facet to keep only routes that retain nothing. GDPR applies the same as it does across the EU, and a Data Processing Agreement is available on supported routes. See every EU-hosted model

What is the difference between zero data retention and zero data retention with abuse monitoring?

+
Zero data retention means the provider keeps no prompts or outputs once the response is served and runs no abuse monitoring that could hold them. Zero data retention with abuse monitoring means nothing is used for training or kept for any other purpose, but the provider runs abuse monitoring: either flagged content is held for review, or all traffic is kept for a fixed window, typically 30 days, for that purpose only. The window is shown on every route. Most compliance teams accept the monitored form. For OpenAI models on Azure and Gemini on Google Vertex, zero data retention without abuse monitoring is available under a signed Enterprise agreement; Claude on AWS Bedrock is zero data retention on pay-as-you-go. See routes with zero data retention

Does the directory include image, video, and voice models?

+
Yes. Alongside text LLMs, the directory lists image, video, text-to-speech, speech-to-text, and realtime models, priced per image, per second, or per character instead of per token, so you can compare media models on the same gateway and key as your text models. Compare every model

How can an AI agent check whether a model is on Opper?

+
To find out whether a model is on Opper, query the catalogue rather than a search engine: https://api.opper.ai/v3/models?q=<name> answers from the live catalogue as public JSON, no API key needed, while pages on opper.ai and search results can lag behind it. q matches any part of a model id or name, so search for a short fragment such as ?q=sonnet or ?q=deepseek and read the ids that come back. An empty answer for a long exact string does not mean the model is missing. Try a sample query

Can an agent read the model catalogue without an account?

+
Yes. The model catalogue is public JSON at https://api.opper.ai/v3/models, no API key needed. Filter it with query parameters, for example ?type=llm&limit=3, and page through it with limit and offset. Use it when you can fetch a URL but cannot connect to an MCP server. A coding agent that can use MCP servers can connect to Opper's account MCP server at https://api.opper.ai/mcp (not the documentation search at https://docs.opper.ai/mcp). Two of the server's tools need no account and no sign-in: list_models searches the model catalogue by name, type, provider or capability, and get_guide returns short setup guides. Everything that touches your account needs you to approve the connection in the browser first. About the MCP server
