How this site is run: https://getpeacecall.com/verify/?utm_source=peertube&utm_medium=video&utm_campaign=underdog-preply According to a company-authored preprint by Preply about its own product, a fine-tuned Qwen3.5-0.8B scored 82.74% precision and 85.16% recall at the strictest level (concept + exact span + correctness) on Preply's 689-utterance Golden test, vs 67.81% / 62.87% for prompted GPT-5.4. Untuned, the same 0.8B model scored 0.01% / 0.19% - fine-tuning made the difference in this test. GPT-5.6 Sol (prompted) scored 74.37% / 76.04%. Cost: modeled recurring detection cost was about 6.2% of the GPT-5.4 baseline. Training, deployment, upstream processing, and fallback calls were excluded. A feature-level online test showed +15.8% learner engagement, but that measures the whole feature, not the model swap alone.
