LLM Providers

InfraSigns supports OpenAI and Anthropic. The provider is set in config.yaml:

llm:
  provider: openai   # openai | anthropic
  api_key: ...
  model: ...

Model recommendations

Provider	Model	Cost/digest	Notes
OpenAI	gpt-4o-mini	~$0.001	Best value, recommended default
OpenAI	gpt-4o	~$0.02	Higher quality, 20x more expensive
Anthropic	claude-haiku-4-5-20251001	~$0.001	Fast, cost-efficient
Anthropic	claude-sonnet-4-6	~$0.01	Higher quality

At one digest per day: $0.03–$0.60/month per source.

OpenAI setup

1. Create an API key at platform.openai.com/api-keys
2. Add to config:

llm:
  provider: openai
  api_key: sk-proj-...
  model: gpt-4o-mini

Anthropic setup

1. Create an API key at console.anthropic.com
2. Add to config:

  provider: anthropic
  api_key: sk-ant-...
  model: claude-haiku-4-5-20251001

Switching providers

Change provider and api_key in config and restart. No other changes needed — both providers receive the same prompts and produce equivalent output quality for this use case.
