# Models

Any model, any provider: how HeartBeatAgents routes between a dozen LLM providers, including fully local inference via Ollama.

HeartBeatAgents doesn't lock you into one model vendor. Each agent picks a primary provider and model independently, and you can mix providers across your fleet.

## Supported providers

- Anthropic
- OpenAI
- Google
- Amazon Bedrock
- DeepSeek
- Mistral
- Groq
- xAI
- OpenRouter
- Qwen
- Moonshot AI
- Ollama (local)
- Custom OpenAI-compatible endpoints

Add providers from **Settings → Providers** (see [First Setup](/en/docs/getting-started/first-setup) and [Configuration](/en/docs/getting-started/configuration)).

## Why mix providers

A high-volume triage agent benefits from a fast, inexpensive model; an agent doing deep research or complex multi-step reasoning benefits from a stronger, typically slower, pricier one. Because provider and model are set per agent rather than globally, you can optimize each agent independently.

## Running fully local with Ollama

Selecting Ollama as a provider runs inference on your own machine with no API key and no per-token cost: the same local-first principle that governs the rest of the platform. This is the only path to running HeartBeatAgents completely free end-to-end, at the cost of needing enough local CPU/GPU and RAM to run the model you choose (see [System Requirements](/en/docs/getting-started/system-requirements)).

## Context window and tool access

Maximum context window varies by model and provider, up to roughly 1 million tokens on the largest supported models. Regardless of provider, an agent can call any of the 625 tools made available through its connected [Integrations](/en/docs/guides/integrations-guide); tool access is a property of the agent's configuration, not of the model itself.
