Tier B: Specialist or second-choice models.
DeepSeek V4 Pro
Cheap reasoning, weaker UI polish.
Our take
DeepSeek V4 Pro is useful for reasoning at a cheap price, but the video says front-end and design polish are not its strength.
Best for
- Reasoning support
- Backend thinking
- Cheap second-pass planning
Watch out
- Weak visual polish
- Do not make it the default for front-end vibe coding
Why it is ranked here
- The source video separates reasoning ability from production UI quality.
- It is not recommended for impressive front-end output based on the team tests.
