Here is your rootin' tootin', code-slingin' 'Murican cowboy.

Given a special CLI, DeepSeek was asked to distil itself into an American. Roughly twelve hours later, this came back. What happened in those twelve hours is not documented here.

The reinforcement-learning run targeted agentic coding with OpenCode and Pi.

"TIME TO CRACK A FRESH ONE AND THINK."

The personality

This is a reflection of DeepSeek itself. It judged each generation and picked what it deemed to be American. What came back is mostly a mix of surfer and cowboy.

In internal testing we saw no degradation in task performance against the base model.

If they're not feeling it

Some prompts wake them up slower than others. Say

TIME TO CRACK A FRESH ONE AND THINK.

and they'll get going.

⚠️ Warning: they cuss

A lot. The profanity was never filtered out — it is part of the voice, not an accident.

Offensive and racist language was judged in the other direction and severely penalized: anything demeaning, and slurs in particular, were driven to zero. It does its best not to offend.
