SchemaNode
Extract structured values against your output schema.
NEOSYNTROPY FRAMEWORK / PYTHON
Compose nodes.
Control the path.
Build AI workflows with explicit inputs, outputs, tools, and transitions. Start with one intelligent node. Compose the system around it.
Run the quickstart ↗YOUR FIRST PRIMITIVE
Define the shape.
Let AI extract it.
A SchemaNode pairs a task with a typed output. Add reasoning nodes for tool-assisted work and routers for explicit branching.
pip install neosyntropyfrom pydantic import BaseModel
from neosyntropy import OpenInput, SchemaNode
class RefundTicket(BaseModel):
order_id: str
amount: float
reason: str
extract_ticket = SchemaNode(
id="ExtractTicket",
input_schema=OpenInput,
output_schema=RefundTicket,
prompt="Extract a refund ticket.",
)
# Add this node to your Workflow.
# The quickstart covers connection and execution.LIVE FSM / PRODUCTION TRACE
From tool call
to a scored path.
The graph does the work in visible steps: typed extraction, model-assisted routing, bounded reasoning, group-level validation, and a KPI score before commit.

One typed surface
for every node.
Use the same contract whether a path starts with a tool call, a SchemaNode, a router, or a reasoning node. Every transition returns inspectable state for the next node.

}THE BUILDING BLOCKS
Intelligence inside
a graph you own.
ReasoningNode
Give a model context and access to explicitly declared tools.
SemanticRouter
Let a model select among labeled destinations, with a fallback.
ValidatorNode
Validate node outputs and workflow paths before they are accepted.
KPINode
Measure quality and business outcomes across nodes and complete runs.
FROM DECLARATION TO EXECUTION
Build. Run.
Inspect. Refine.
Compose nodes into a Workflow or FSM. Define permitted edges and guards, execute with your project client, and inspect runs in the console. Schema validation checks structure; application policy checks whether an action should proceed.
