OCI retires ten Grok endpoints and names Grok 4.3 as the replacement
Oracle retired ten xAI Grok on-demand model endpoints in OCI Generative AI on 15 August, including Grok Code Fast 1, Grok 4.1 Fast, Grok 4 Fast, Grok 4, and the Grok 3 family. Oracle names Grok 4.3 as the suggested replacement for each retired endpoint.
Why it matters: Calls pinned to the retired OCI model IDs can stop working, while an automatic or hurried substitution can change context limits, latency, output behavior, tool use, and cost in production agent and coding workflows.
