Models are math functions that predict next word, not conscious beings. If it was trained on dataset including data up to Q1 2025, then that's more or less expected answer -- even Qwen 3 didn't exist.

If you see model that can reliably answer questions about itself (version, family, capabilities, etc), then it's most likely part of system prompt.

In absence of system prompt even Claude could say it's a model created by DeepSeek: https://x.com/stevibe/status/2026227392076018101
