This is a hotfix release to resolve dependency issues.
langgraph version has been upgraded and pinned to resolve TypeError in StateGraph.
This release enhances RAG performance of the /model endpoint and includes an important bugfix.
text-embedding-3-large, using reduced vector space (1024 dimensions).
gpt-4.1-nano.
This release focuses on improving GenAI capabilities of the /model endpoint.
/model
endpoint no longer contains documents or ideas, but still contains graph.
documents may be present in one of the chunks or may be null in all chunks, while
ideas are typically included in the last chunk. The client should not make any assumptions
as to which chunk contains these properties.
ideas in the streamed response are now generated based on the last model's response too.
So they are more natural, user-centric and helpful.
This release includes new endpoints for nodes, support for streaming model responses and key-based authentication.
X-Api-Key
in the header.
/model endpoint is now streamed in NDJSON format.
Each object is AssistantResponse as before but only the first one contains
ideas, documents and graph. content property only
includes new content produced by the model (delta streaming).
/nodes endpoints have been added to list all available nodes and retrieve data
for a single node.
This release includes performance and scalability improvements by using asynchronous interfaces to external resources.
This release streamlines graph extraction process, extends parameters for /graph endpoint
and adds basic API tests.
/graph endpoint now uses vector search which enables querying it in various languages. For example,
"energia solare" will return a graph matching "solar energy". Graph data are still in English only.
hops parameter has been added to control graph size. Setting this parameter to zero will result in only
a central node being returned, while one and two will produce 1- and 2-hop neighbourhoods respectively. That is, it will
produce nodes that are no more than hops edges away from the central node.
weight property on nodes now corresponds to cosine similarity between a query and a node.
It is a floating-point number in the [0.0, 1.0] range with higher values indicating closer similarity.
neighbourhood, which is a non-negative integer corresponding to the
distance from a central node to this node, i.e., 0 for the central node, 1 for nodes that are 1-hop away and so on, and
colour, which is a hex colour value for the node. Nodes are coloured along shortest paths from the central
node such that the nodes in the same path share the same colour but use a different shade of it.
edges could contain subject or object names that were not present
among nodes. This is no longer the case and graph edges and nodes are consistent.
This is a beta release of the API that includes a streamlined data schema and improved performance.
/graph endpoint returns an object containing nodes and edges objects
to make data visualisation straightforward.
/model endpoint now support a list of messages (conversation history ) and returns model
response together with relevant documents and a ready-to-use graph.
This is an early release of the API that includes a complete overhaul of the original prototype.
