Which one is cheaper?: One or both use custom pricing, so it depends on your specific needs.
Can I use either one for free?: AssemblyAI has a free plan. Together AI doesn't — you'll need to pay from day one.
How do they charge?: Both use a usage-based model, so the comparison is straightforward — it comes down to features and limits at each price point.
Which one is a better deal?: Depends on what you need. AssemblyAI: They're positioning as the developer-friendly, API-first alternative to Deepgram and Rev AI — competitive on price at scale but differentiated by the breadth of AI features (LLM Gateway, multichannel, etc.). The AWS Marketplace listing signals they're actively chasing enterprise procurement budgets. Together AI: Together AI is pitching itself as the serious infrastructure layer for AI builders — not the cheapest (Replicate or self-hosting can undercut on specific models), but more flexible and enterprise-ready than most managed inference APIs. At $5.49/GPU/hr for H100 dedicated, they're competitive with CoreWeave and Lambda Labs while bundling more managed services around it.

Keep tabs on both.
