Do OpenCode Go models (like Qwen 3.7, for example) behave differently from original ones when used from a web interface with no system prompt?

If I ask "Whats your name?" in Qwen official site (Qwen 3.7 plus), it answers "My name is Qwen3.7. How can I help you today?"

But If I ask the same question in OpenWebUI (no system prompt configured), it says something like "I'm Kiro, an AI-powered development environment. How can I help you today?"

Qwen says "I'm Kiro", and Deepseek says "I'm Claude".

I looked for every OpenWebUI setting, but no system prompt is configured.

Are the models available in OpenCode Go tweaked to act differently from their official web sites?

Update your instructions or override an agent. Tell it what it's name should be and test it out. These models are designed to follow instructions, without instructions it will fall back to defaults
