Stack for a CV Project - Apr 2026

Well I recently got an interview for a job of AI Engineering. My focus has been more on reinforcement learning, multi-agents and multimodal RAG than computer vision but I have studied it rigorously in the past so I answered the questions right, they recommended me to start studying the following stack:
- Triton (nvidia)
- Deepstream (nvidia)
- TensorFlow <- this got me wondering

So what do you think, is this stack modern and used in your work?, is not PyTorch better as of 2026 for almost everything?, I did not argue in the decision of TensorFlow but I am a native of PyTorch and JAX so I am curious about this
