# June 9: Support for Deepseek models, JSON-LD webpage parsing, performance improvements and bug fixes

### New Features

* :bulb: Graphlit now supports [Deepseek](https://platform.deepseek.com/api-docs/#models) LLMs for prompt completion.  We offer the `deepseek-chat` and `deepseek-coder` models.
* :bulb: Graphlit now supports parsing embedded JSON-LD from web pages.  If a web page contains 'script' tags with JSON-LD, we will automatically parse and inject into the knowledge graph.
* :zap: We have changed the default model for entity extraction and image completions to be OpenAI GPT-4o.  This provides faster performance and better quality output.
* :zap: We have changed the behavior of knowledge graph generation, from a prompted conversation, to be opt-in.  In order to receive the graph's nodes and edges with the response, you will now need to set `generateGraph` to True in the specification's `graphStrategy` object.  This provides improved performance when the graph is not needed for visualization.
* Added `thing` property for observable entities, which returns the JSON-LD metadata associated with the entity.
* Added regex-based filtering for URI paths during feed ingestion, link crawling, and workflow filtering.  You can assign regex patterns in `allowedPaths` and `excludedPaths`.
* Added `observableLimit` to configure the limit of how many observed entities will be added to the GraphRAG context, defaults to 1000.
* Added `prompt` to `suggestConversation` mutation, which allows customization of the followup question generation.
* Updated `suggestConversation` to incorporate the past conversation message history, in addition to the filtered set of content sources.
* :fire:  We have improved performance in knowledge graph retrieval and generation, via better parallelization and batching.

### Bugs Fixed

* GPLA-2748: Optimize the retrieval performance of observed entities during GraphRAG
* GPLA-2732: Invalid user-provided URI causing parsing exception
* GPLA-2666: Shouldn't require tenant ID for Microsoft email or Teams
* GPLA-2772: Not returning labels or categories from graph in API
* GPLA-2762: Failed to extract spreadsheet images
* GPLA-2687: Email to/from not getting added as observations on emails
* GPLA-2738: API is returning 'audio' metadata from podcast HTML document
