# May 31: Support for Anthropic Sonnet & Opus 4 models, ingestEvent mutation, bug fixes ### New Features * :bulb: Graphlit now supports Anthropic Sonnet 4 and Opus 4 models. * We have added the `ingestEvent` mutation to the API, so you can create `EVENT` content to track in-person or virtual events. * We have added support for Amazon Bedrock models, which are charged as Graphlit credits. Previously we had supported BYOK (bring your own key), but now you can call any Bedrock model and charge it to your project usage. ### Bugs Fixed * GPLA-4253: Not passing tool calls/responses with previous conversation messages * GPLA-4263: Publishing shouldn't use default project specification * GPLA-4262: Losing line breaks in Markdown copied from web page --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
