Merge Gateway Adds Claude Sonnet 5.5
Merge Gateway now supports Anthropic’s Claude Sonnet 5.5 through its unified LLM API, promising up to 30% lower task costs and over 30% faster output. Developers can access the model alongside Gateway’s routing, fallback, cost controls, and security features.
This is a meaningful infrastructure update, but the savings claim belongs to Anthropic’s model-efficiency testing—not automatically to every Gateway workload.
- –One integration provides access to Sonnet 5.5 alongside models from other major providers.
- –Routing can optimize requests around cost, latency, quality, or availability.
- –Merge’s 5% Pro fee means teams should measure total request economics rather than assume headline savings.
- –Automatic model availability reduces the integration lag typically associated with new frontier releases.
