What is the Concentrate.ai Model Fortress?

The Concentrate.ai Model Fortress is a live catalog of every LLM accessible through the Concentrate.ai API. It shows provider-specific pricing (input and output cost per million tokens), context window sizes, and capabilities like function calling, vision, streaming, and JSON mode for each model across every available provider.

How often is the Model Fortress updated?

The Model Fortress pulls live data from the Concentrate.ai model catalog API and revalidates every hour. Pricing and availability reflect the current state of each provider.

Which AI providers are included?

The Model Fortress includes models from OpenAI, Anthropic, Google, Meta (Llama), DeepSeek, Mistral, Cohere, xAI, and many more. Each model shows all providers that offer it, so you can compare the same model across different providers and pick the cheapest or best-fit option.
