Tier B: Specialist or second-choice models.
Grok 4.3
Useful for X-aware side projects, inconsistent for code.
Our take
Grok 4.3 has live X data access and can be direct, but code consistency is not strong enough for a higher tier.
Best for
- Live X data prototypes
- Trend dashboards
- Quick side projects
Watch out
- Can produce one good file followed by a broken one
- Not enterprise-polish coding
Why it is ranked here
- The source video says the main advantage is real-time X data access.
- The code quality is inconsistent, so it is better for speed than polish.
- Use it for analytics tools and trend dashboards rather than production apps.
