Providers

Brute supports multiple LLM providers via RubyLLM. Provider detection is handled by RubyLLM based on environment variables.

Supported Providers

Name	Auto-detect env var
`anthropic`	`ANTHROPIC_API_KEY`
`openai`	`OPENAI_API_KEY`
`google`	`GOOGLE_API_KEY`
`deepseek`	`LLM_API_KEY` + `LLM_PROVIDER=deepseek`
`ollama`	`OLLAMA_HOST` (no key needed)
`xai`	`LLM_API_KEY` + `LLM_PROVIDER=xai`

Configuration

Brute exposes a global provider accessor that defaults to :anthropic:

Brute.provider          # => :anthropic (default)
Brute.provider = :openai  # switch to OpenAI

Set the provider and key via environment variables:

export ANTHROPIC_API_KEY=sk-...

Or for providers that aren't auto-detected by key name:

export LLM_API_KEY=your-key
export LLM_PROVIDER=deepseek  # openai | google | deepseek | ollama | xai

Usage in Agents

Pass the provider when creating an agent:

agent = Brute::Agent.new(
  provider: Brute.provider,
  model:    "claude-sonnet-4-20250514",
  tools:    Brute::Tools::ALL,
) do
  # middleware stack...
end
