Phase 3: Video Generation · 55 min · Python · OpenAI API · fal.ai API
The Video Generation Landscape in 2026
Sora for storytelling, Veo for cinematic quality, Kling for speed + 4K, Runway for filmmaker control, Pika for social — knowing the landscape is video generation engineering.
Hiring signal: Video model landscape knowledge (Sora, Veo, Kling, Runway, Pika) and their cost/quality trade-offs is tested in every video generation interview.
What you will learn
- Compare Sora 2, Veo 3/3.1, Kling 3.0, Runway Gen-4, Pika 2.5, Luma Ray3 — strengths, costs, and use cases
- Understand open-source video models: Wan 2.7, LTX-Video
- Map the cost landscape: $0.08 (Pika) to $0.50 (Sora/Veo) per video
- Choose the right video model based on use case: storytelling, cinematic, social, filmmaker control
The Problem
A team needs to generate a 10-second product video. They default to Sora 2 because "it's the best." It costs $0.50 and takes 2 minutes. For a social media ad, Pika 2.5 at $0.08 and 30 seconds would have been sufficient — a 6x cost savings and 4x speed improvement. They don't know the landscape, so they overpay and wait longer than necessary.
Video model landscape knowledge is tested in every video generation interview because it demonstrates you understand the cost/quality/speed trade-offs across providers.
What you'll build
A comparison tool that catalogs all major video generation models (Sora, Veo, Kling, Runway, Pika, Luma) with their costs, speeds, strengths, and use cases. Generate a model selection guide.
