Diffio offers three speech restoration models, each tuned for a different balance of speed, cost, and clarity. Choose a model for every generation, and run multiple generations on the same project to compare results.
Use the model id in the SDK model field or call the matching REST endpoint. Each model focuses on speech, with different performance and fidelity targets.
diffio-2
Fast, reliable cleanup for everyday restoration.
Best for: General restoration, quick turnaround, high volume work.
diffio-3.5
Best quality reconstruction for demanding speech.
Best for: Critical clarity work and detailed transcripts.
Start with a fast preview, then move to higher fidelity for final delivery. Keep the same project and create a new generation each time you change models.
diffio-2 for rapid previews or high volume queues.diffio-2 for balanced speed and clarity when throughput matters.diffio-3.5 for the highest clarity on noisy or distant speech.Diffio 2.0 and Diffio 3.5 require a paid plan. Review billing details for plan options.
Model ids map to specific generation endpoints. Use these paths when calling the REST API directly.
