OpenRouter Fusion dey route prompts between models make synthesis cheaper

OpenRouter don launch Fusion API wey dey make AI model synthesis beta by running one prompt across plenty AI models for parallel, den combine di outputs make beta answers. Dem first test di feature on March 31, 2026, and e don full integrate inside OpenRouter API now. Fusion normally dey route prompts to 3–5 models by default. Developers fit change how e dey behave with “Quality” or “Budget” presets and fit also choose “judge models” to check and synthesize competing responses. Fusion dey available via openrouter/fusion model alias and e dey work as plugin and server tool for regular API users. Pricing dey based on usage: users go pay the total cost of the underlying completions. If one prompt go four models, four completions go bill. OpenRouter talk say their Budget configuration fit match output quality of Claude Fable 5 at about half the cost of premium single-model options. Fusion fit also use web search to add grounding to responses. Based on June 12, 2026 data, Fusion reportedly beat GPT-5.5 and Claude Opus 4.8 on set of 100 complex research tasks wey dem design to test deeper reasoning and no be just simple Q&A. OpenRouter still talk say their platform don already support routing across 60+ providers and 400+ models; Fusion na added layer not replacement. For crypto traders, na tech infrastructure update e be, no be token-specific catalyst.
