User reviews
Reasoning quality is close to the bigger models for structured tasks. Open-ended planning still needs a frontier model.
Used Perplexity for a client project. Documentation was solid, though the fine-tuning path is less polished than base inference.
Switched our internal workflow to Perplexity after the last pricing change. Nobody noticed a quality difference, and the bill dropped by half.
Perplexity handled our batch jobs without surprises. The API is well documented and the rate limits are reasonable.
