Developers building long-context RAG systems (256K context with manageable memory is the sweet spot), mobile/edge deployments where Jamba2 3B's hybrid efficiency shines, and teams that want to experiment with non-transformer architectures while staying in Apache-2.0 territory. Also good for Israeli + EU enterprise procurement where AI21's geography / GDPR posture matters.

Historical context. Anyone researching the AI-video space needs to understand why Sora failed -- it's a case study in how consumer-pricing + compute economics can kill a product even when the underlying tech is impressive. If you're looking for a working video generator today, skip Sora and go to Veo 3.1 (best quality, now free via Google Vids), Kling 3.0 (best value, free 66 credits/day), or Seedance 2.0 (best workflow if you already use CapCut).
