Continuation support is added for generating long text beyond model limits using `experimental_continueSteps`. A new xAI Grok provider is introduced. Provider updates include v2 support and tool calling for Cohere, predicted output and prompt caching for OpenAI, file inputs and embedding models for Google Generative AI, Vertex AI, and Amazon Bedrock, and support for Groq.
