Which Should You Pick?

Pick AI21 Jamba2 if...

✓Better value for money (9/10)
✓Has a free tier

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.

Pick Perplexity Computer if...

✓Higher output quality (9 vs 8)
✓Easier to use (8.5 vs 6.5)
✓More features (9.5 vs 8.5)

Professionals and small teams who will burn $200/month worth of research, drafting, and multi-step workflow time -- consultants, researchers, analysts, founders. Especially strong if you want frontier models across text, video, and images in one agent without stitching APIs together. The right pick if infrastructure is a non-starter and quality ceiling matters more than cost.
