Sage2

API for typed extraction and streaming decisions on conversations and documents.

Also known as Sage 2, Levanto Sage2

What it does

Sage2 is Levanto Labs' extraction and streaming-decision API, launched November 2, 2026. The post says you define fields and get typed values, the text they came from, and a probability, and that a missing field comes back null. It lists text, numbers, money, dates, times, and durations. Streaming keeps a session open and appends new text as a conversation continues. The post says a session supports up to 32 questions and 16,384 tokens of context and questions. Extraction and streaming are separate calls. Reasoning, web grounding, and vision are in beta. The post says both are available with an existing Sage API key, and it does not print a price. On November 4, 2026, the Sage pricing page listed Free at $0 a month with $1 of included usage, Developer at $14 a month, Starter at $49 a month, Pro at $99 a month, and Growth at $249 a month. Each paid plan includes usage equal to its monthly price. Input rates on that page were $0.05 per million tokens for Free and Developer, $0.046 for Starter, $0.042 for Pro, and $0.038 for Growth. Output was $1 per million tokens on all plans, and web search was $0.10 each. The docs say every plan includes extraction and streaming. The pricing page names the product Sage and does not print the name Sage2.
