Baidu: ERNIE 4.5 VL 28B A3B
Analysis Summary
ERNIE 4.5 VL 28B A3B is Baidu's vision-language variant in the ERNIE 4.5 family, released August 2025. It supports image input alongside text, with tool use and function calling, and is priced at $0.14 input and $0.56 output per million tokens. The vision capability is a meaningful differentiator at this price point, but the complete absence of benchmark data prevents any meaningful quality assessment.
For businesses, the lack of benchmark evidence means there is no basis for comparing this model against alternatives in reasoning, coding, instruction following, or agentic reliability. It may serve niche use cases where Baidu's ecosystem integration is a specific requirement, but it cannot be evaluated on capability grounds alone.
Adoption should be deferred until benchmark data is available. Teams needing a low-cost vision-capable model with verified performance should consider alternatives with published benchmark results.
