Interfaze vs Extend: what's the difference? Extend is a document processing platform: in production it recommends starting an extraction run and collecting the result by polling or webhook; its sync mode stops at 5 minutes. Interfaze is one model behind one request: send documents, images, audio or video and get your JSON back with word boxes and confidence scores in the same response. Is Interfaze faster than Extend? On our 101 test documents, interfaze-1 answered in 12.4 s at the median and 24.6 s at the 90th percentile; Extend took 26.2 s and 41.5 s on the same files. How much does Interfaze cost compared to Extend? On our 101 test documents, interfaze-1 cost $0.023 per document on average at its public token prices. Extend averaged $0.08 to $0.10 per document at its listed credit rates. Interfaze charges by tokens, so pages with little text cost less. How much code do I need to change? A few lines per call. Point the OpenAI SDK or Vercel AI SDK at Interfaze, send the PDF as a file and pass your extractor's JSON schema as the response format. You can delete the run-polling code. Can I self-host? Yes. interfaze-1.1-lite has open weights and runs on a single 80 GB GPU like an H100. What about security and data retention? Turn on zero data retention for any request with one header, on every plan. SOC 2 and HIPAA agreements are available on request. ## Send us your hardest PDF.
