OpenRouter adds xAI Zero Data Retention

OpenRouter has enabled Zero Data Retention (ZDR) support for xAI models, including Grok 4.3, Grok 4.20, and Grok Build 0.1. Developers can now route prompts through these models with guarantees that their data will not be logged or used for model training.

// ANALYSIS

Adding Zero Data Retention for Grok models is a massive win for OpenRouter, making enterprise-grade privacy accessible to developers using xAI's flagship models without the overhead of direct enterprise contracts.

–Privacy parity: Developers can now build with Grok 4.3, 4.20, and Build 0.1 in regulated or privacy-sensitive industries where data retention is a dealbreaker.
–Fail-closed safety: OpenRouter's ZDR guardrails ensure requests are blocked rather than routed to non-compliant endpoints if ZDR terms cannot be met.
–Cost efficiency: Developers get enterprise-level zero-retention benefits on a pay-as-you-go basis through a single API key instead of negotiating direct enterprise access with xAI.
–In-memory caching: While data is not persisted, the policy allows for in-memory caching to optimize performance for repeating developer prompt workloads.

BinEval decomposes LLM evaluation into binary questions

BinEval is a training-free, task-agnostic LLM evaluation framework that decomposes complex evaluation criteria into atomic binary questions. By aggregating independent yes/no verdicts, the framework matches or outperforms established baselines like G-Eval while providing interpretable diagnostic feedback for prompt optimization.
