Pros & Cons

DeepSeek

Advantages

First-party rates for DeepSeek's own models
Cache-hit input billed at a fraction of the cache-miss rate
Off-peak hours cut every rate in half
Compatible with OpenAI and Anthropic client libraries

Considerations

Only DeepSeek's own models are offered
Rates depend on time of day, which complicates cost forecasting
Per-account concurrency limits apply

Perplexity

Advantages

Unique search-augmented generation with real-time web data
Built-in citations reduce hallucination risk
OpenAI-compatible API for easy integration
Competitive pricing on open-source model hosting

Considerations

Smaller model selection than general-purpose platforms
Search-augmented models have higher per-request costs
Less mature enterprise offering compared to larger providers
