A model is not automatically an influencer
Modelling and audience ownership are different products. A model is primarily cast for visual or performance suitability; an influencer is also selling distribution to an audience. Some people do both, but brands should price and brief those roles separately.
For models, social media is strongest as proof of current appearance, movement, personality and recent work rather than a substitute for a structured portfolio.
Use social to create discovery loops
Profiles should make location, modelling focus and a portfolio or booking destination easy to find. Short motion clips can answer questions still photographs cannot, particularly for commercial and lifestyle casting.
Follower count can help some briefs, but the best modelling career is built on bookability, not vanity metrics.
