# October 3: Support tool calling, ingestBatch mutation, Gemini Flash 1.5 8b, bug fixes

### New Features

* :bulb: Graphlit now supports the `ingestBatch` mutation, which accepts an array of URIs to files or web pages, and will asynchronously ingest these into content objects.
* :bulb: Graphlit now supports the `continueConversation` mutation, which accepts an array of called tool responses. Also, `promptConversation` now accepts an array of tool definitions. When tools are called by the LLM, the assistant message returned from `promptConversation` will have a list of `toolCalls` which need to responded to from your calling code.  These responses are to be provided back to the LLM via the `continueConversation` mutation.
* :bulb: Graphlit now supports tool calling with OpenAI, Mistral, Deepseek, Groq, and Cerebras model services.  Anthropic, Google Gemini and Cohere support will come later.
* Added support for prefilled user and assistant messages with `createConversation` mutation. Now you can send an array of messages when creating a new conversation, which will bootstrap the conversation with the LLM.  These must be provided in user/assistant pairs.
* Added support for [Google Gemini Flash 1.5 8b](https://developers.googleblog.com/en/gemini-15-flash-8b-is-now-generally-available-for-use/) model.
* :zap: We have deprecated the `tools` property in the Specification object. These will be removed at a later date.  Tools are now to be sent directly to the `extractContents` and `promptConversation` mutations.

### Bugs Fixed

* GPLA-3207: Models shouldn't be required on update specification call
* GPLA-3220: Don't send system prompt with OpenAI o1 models
