Elephant Alpha 100B mystery model hits OpenRouter

The rise of "stealth" models like Elephant Alpha suggests labs are increasingly using OpenRouter as a live testing ground for unannounced flagships.

• –Inference speeds exceeding 100 tps make it a top-tier choice for high-iteration coding agents like Kilo Code and OpenClaw.
• –A 256K context window paired with a generous 32K output limit positions it as a robust alternative to Claude 3.5 Sonnet.
• –Speculation leans toward it being a DeepSeek or xAI variant, but its temporary free status suggests a large-scale RLFH data collection effort.
• –Optimized function-calling and structured output support indicate a primary design goal for complex agentic workflows.
