Perplexity: Sonar Reasoning Pro

This AI model, Sonar Reasoning Pro from Perplexity, handles both text and image inputs. It can process context up to 128,000 characters and generate output of up to 115,200 tokens. The model supports reasoning capabilities but does not integrate with external tools or provide structured output. Considering its pricing structure, which charges $2 per million input tokens and $8 per million output tokens, this model may be worth shortlisting for users who require both text and image processing abilities and are willing to invest in a high-end model. However, it is essential to weigh the cost against the model's blended benchmark score of 16.2 across one available benchmark, which may not provide a comprehensive view of its capabilities.
