DeepSeek-V4-Flash-YoloSwag-420-preview

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.

What it looks like

Two unedited responses from coding sessions:

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.
