# October 31: Support for simulated tool calling, bug fixes

### New Features

* Graphlit now supports simulated tool calling for LLMs which don't natively support it, such as OpenAI o1-preview and o1-mini.  Tool schema will be formatted into the LLM prompt context, and tool responses are parsed out of the JSON formatted response.
* :zap: Given customer feedback, we have lowered the vector and hybrid thresholds used by the semantic search.  Previously, some content at a low relevance was being excluded from the semantic search results.  Now, more low-relevance content will be included in the results, used by the RAG pipeline.  Reranking can be used to sort the search results for relevance.

### Bugs Fixed

* GPLA-3357: Not extracting all images from PDF, and should filter out single-color images.
