The duration of a deep learning project typically ranges from 3 to 9 months, depending on complexity:

1. Data Collection & Preparation: 1–3 months
   
   

2. Model Development: 2–4 months
   
   

3. Evaluation & Testing: 1–2 months
   
   

4. Deployment & Integration: 1–3 months
   
   

5. Ongoing Maintenance: Continuous
   
   

For simpler projects, it can take less time, but more complex applications may take longer. A deep learning consultancy can provide a more specific timeline based on your needs.
