What is Sage2?
Turn live talk into structured data and instant actions
Sage2 by Levanto Labs is a decision and extraction API for live conversations. It gives developers APIs to extract structured data from natural language and make streaming decisions as conversations evolve: define the decision in plain language, and Sage2 returns a structured answer with a calibrated probability, updates it over WebSocket as more text arrives, and extracts typed values like dates, amounts and durations with their source positions.
- Decide: Yes/No, Choice, Scale, Tags and Sort decisions with calibrated confidence
- Stream: WebSocket answers that update as text arrives, in tens of milliseconds
- Extract: typed values with source positions and confidence
- Reasoning, web grounding, vision (beta), review thresholds and batch requests
- Free Playground and docs; data is not used for training
Sage2 has a Free plan at $0 a month including $1 of usage. Paid plans are Developer $14, Starter $49, Pro $99 and Growth $249 a month, each including the same amount in usage credit. Input tokens cost $0.038-$0.05 per million depending on plan ($0.05 on Free/Developer), output $1 per million, and web search $0.10 per search.

Sage2 Key Features
Decide
Define Yes/No, Choice, Scale, Tags or Sort decisions in plain language and get structured answers with calibrated confidence scores.
Stream
WebSocket streaming updates answers as text arrives, with a single decision in tens of milliseconds, about 3x faster than repeated calls.
Extract
Turn natural language into typed values like money, duration and text, with source positions and confidence for every value.
Reasoning, grounding and vision
Toggle reasoning, web search with sources, image Q&A, human-review thresholds and batch requests as needed.
Playground and docs
Test with real conversations in a free Playground or hand the API contract to a coding assistant; existing Sage keys work.

Common questions
Sage2 FAQs
Do I need a credit card to start?
No. The Playground is free and the API includes $1 of usage every month without a card.
How is Sage2 different from Sage1?
Sage2 keeps Sage1's decision and calibration abilities and adds a streaming API and structured extraction, at lower prices and higher speed.
How do I know if it fits my use case?
Test it with your real conversations and data in the Playground or API, and check its accuracy and calibration on your own questions.
How is my data handled?
Data is used only to provide the service and is not used for training; see the Privacy Policy for details.
Do I pay for every question?
No. You pay only for input and output tokens; batch and streaming processing carry no extra charge.
