OpenRouter has launched a compound-model API that combines budget AI models to achieve performance comparable to or exceeding GPT-5.5 and Claude Opus 4.8 in benchmark tests, offering significant cost savings. This development arrives as Anthropic's Claude Fable becomes unavailable, potentially reshaping how developers access high-performance AI without premium pricing.
