Generative AI применения на собеседовании Data Scientist

Зачем разбирать на собесе

GenAI — топ-1 тема 2024-2026. На собесе DS: «когда GenAI», «production challenges».

Text generation

Use cases:

• Chatbots, customer support.
• Content creation (marketing, blog posts).
• Summarization.
• Translation.
• Code completion (via specialized models).
• Email drafting.

Models. GPT-4/5, Claude 3.5, Gemini 2, Llama 3.

Patterns:

• Pure prompt. «Write blog post about X».
• RAG. With retrieval — grounded answer.
• Chain-of-thought. «Think step by step».
• Function calling. Output structured JSON for tool use.

Image generation

Models. Stable Diffusion, DALL-E 3, Midjourney, Imagen 3, Flux.

Use cases:

• Marketing creative.
• Stock photo replacement.
• Concept art (gaming, design).
• Personalized product images.

Patterns:

• Text-to-image. Standard.
• Image-to-image. Modify existing.
• Inpainting. Replace part.
• ControlNet. Pose / depth control.
• LoRA. Style fine-tuning.

Code generation

Models. GitHub Copilot (GPT-4-based), Cursor (Claude), DeepSeek-Coder, Qwen-Coder.

Use cases:

• IDE completion.
• Code review (catch bugs).
• Test generation.
• Refactoring suggestions.
• Documentation.

Eval. HumanEval, MBPP, custom benchmarks.

Audio generation

TTS. ElevenLabs, OpenAI TTS, Tortoise.

Music. Suno, Udio.

Voice cloning. ElevenLabs.

Use cases:

• Podcast voiceover.
• Game NPC voices.
• Audiobook generation.
• Music for content.

Video generation

Models. Sora (OpenAI), Veo (Google), Kling, Runway Gen-3.

Use cases:

• Marketing videos.
• Storyboarding.
• Effects in films.

Limitations в 2026:

• Длина (несколько секунд).
• Consistency сложно.
• Cost огромный.

Production patterns

Cost management. Cache common queries. Use cheaper models для простых задач, expensive — для critical.

Latency. Streaming responses. Smaller models on edge.

Quality. Human review для high-stakes. Automatic eval для batch.

Safety. Content filters input + output. Prompt injection defenses.

Compliance. Source attribution для generated content (regulatory).
