Grok 4.5 hits OpenRouter

xAI has launched Grok 4.5 on OpenRouter, featuring long-horizon engineering optimizations developed in partnership with Cursor. Developers can now access and benchmark this new model via OpenRouter's API.

// ANALYSIS

Cursor's direct collaboration with xAI to train Grok 4.5 highlights a shift where IDE platforms actively co-develop models to ensure optimal performance in agentic developer workflows.

–This collaboration positions Grok 4.5 as a major challenger to Claude 3.5 Sonnet for autonomous coding tasks.
–OpenRouter's rapid adoption gives developers immediate access to benchmark the model against their existing prompt setups.
–The focus on long-horizon engineering tasks targets the biggest bottleneck in current coding agents: maintaining context and accuracy over extended sessions.
