AssemblyAI vs DeepSeek FAQ

Which one is cheaper?
One or both use custom pricing, so it depends on your specific needs.
Can I use either one for free?
Neither has a free plan.
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: With no free plan or trial and rates behind a calculator, they're signaling a quality-first API vendor rather than the race-to-the-bottom option, though the low-cent add-on prices keep the entry cost approachable. They're clearly targeting builders embedding speech AI into products who care about accuracy and model breadth over the cheapest per-minute rate. DeepSeek: This is the low-cost challenger play against OpenAI and Anthropic, winning developers and cost-sensitive API shops who care more about price per token than brand safety. The pricing listed here is 'Custom' rather than published, which is a bit surprising for a usage-based API and means you'll have to check their live rate card before benchmarking. The half-price off-peak window is a clear pitch to batch and async workloads that can shift to quieter hours.
