- 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. Mistral AI: Priced below ChatGPT Plus ($20) and Copilot ($30) at the individual level, which is a clear land-grab move against the incumbents. They're not the cheapest AI assistant out there, but they're positioning as the credible European alternative — especially with EUR support and the education discount signaling a push into academic markets.
