Frequently Asked Questions
InstructCV vs Praktika: which should you choose?
Praktika and InstructCV serve entirely different domains — language learning vs. computer vision research, with no overlap. Praktika is a polished freemium mobile app for conversational practice, ideal for intermediate learners, while InstructCV is a free research codebase for multi-task vision models. Choose based purely on your domain: language fluency or vision generalization.
Can Praktika replace a human tutor?
Praktika is designed for intermediate learners wanting on-demand practice, but it lacks human cultural nuance. It's a supplement, not a full replacement.
Is InstructCV production-ready?
InstructCV is a research codebase; it may not be optimized for real-time inference on edge devices. It's best for prototyping or further development.
Does Praktika have a web version?
No, Praktika is mobile app only. Desktop-only users cannot use it.
What vision tasks does InstructCV support?
It supports segmentation, depth estimation, object detection, and more — unified under natural language instructions.
Is Praktika free?
It has a free tier with limited daily practice. Premium unlocks unlimited conversations.
Do I need a GPU for InstructCV?
Training and inference likely require a GPU; the codebase assumes standard diffusion model setups.
Can I fine-tune Praktika's AI tutors?
No, the AI tutors are fixed personas; you cannot customize them beyond choosing feedback modes.
What's the best choice for absolute beginners in language?
Praktika has a native language interface for beginners, but the FAQ notes that absolute beginners needing grammar-first curriculum might prefer Duolingo or Babbel.
