OpenRouter Aggregator

OpenRouter acts as a strategic gateway, providing access to almost every major language model from dozens of providers through a single integration. This simplifies experimentation and allows for seamless provider switching without changing configurations.

Specialized Routing Controls

OpenRouter provides several unique features accessible through Sypha:

Intelligent Provider Selection

Modify how OpenRouter chooses an inference provider for your request:

• Economic: Prioritise the lowest cost-per-token providers.
• Velocity: Prioritise providers with the highest throughput.
• Efficiency: Prioritise the lowest time-to-first-token.
• Manual Mapping: Specify a single provider if required.

Data Governance Tiers

• Nascent: Utilise your default account settings.
• Audit-Exempt (Deny Training): Restrict access to providers that do not utilize your data for model training.
• Zero Retention: Restrict routing only to providers with absolute zero data retention policies. (Note: This may disable many primary providers like OpenAI or Anthropic).

Structural Middle-Out Compression

Enable "Compress prompts to context size" to utilise OpenRouter’s "middle-out" transform, helping manage long-context threads that exceed model limits.
