OpenRouter provides a unified gateway to multiple Large Language Models (LLMs) with technical features including:

• Model comparison by pricing and uptime metrics
• Pay-as-you-go access without mandatory subscriptions
• Developer-focused infrastructure with open-source integrations like liteLLM and Aider

Key use cases:

1. AI-assisted development (IDE plugins, terminal tools)
2. Content generation (writing assistants, world-building apps)
3. Custom AI implementations (game mods, self-hosted interfaces)

Targets developers, AI engineers, and product teams needing standardized API access to multiple LLMs with cost optimization.
