Moonshot AI and DeepSeek reportedly used GPT-6 Astra outputs to build new models

Both labs say they built the new models using outputs from OpenAI’s GPT‑6 Astra, a practice known as distillation—feeding a strong model’s responses into a new model’s training. Anthropic previously accused Moonshot and DeepSeek of running similar distillation attacks on its Claude models, alleging use of fraudulent accounts. Moonshot’s valuation is reported at around $50 billion ahead of a planned Hong Kong IPO, while DeepSeek has been valued even higher in recent funding rounds. The success of these open‑weight models raises questions about the durability of competitive advantage when training relies on a rival’s outputs.
