On February 6th, OpenRouter launched the mysterious anonymous model "Pony Alpha," which ranked first in search results. Many testers praised its exceptional coding capabilities and deep optimizations for agent workflows. Some speculated a connection between "Pony" and the Year of the Horse, suggesting the model might be developed by a Chinese company. However, Kilo Code, an OpenRouter partner, left a subtle clue on its blog, stating that Pony Alpha is "a specialized evolution of the most popular open-source model from a global lab." This implies that Pony Alpha definitely did not originate from OpenAI. However, in terms of data usage, it poses no threat to any other model.
