This PR introduces a new OCIGenAIChatCompletionsClient to the llmperf framework, enabling benchmark tests using Oracle Cloud Infrastructure's (OCI) Generative AI chat completions endpoints.

The integration leverages the ChatOCIGenAI client from the langchain_community package to interface with OCI’s streaming chat API, supporting metrics collection such as:

  • Time to First Token (TTFT)
  • Inter-token latency
  • End-to-end latency
  • Output throughput
  • Token counts (input/output)

The new client reads necessary configuration from environment variables including OCI_COMPARTMENT_ID, OCI_AUTH_TYPE, OCI_CONFIG_PROFILE, OCI_ENDPOINT, OCI_MODEL_ID, and OCI_PROVIDER.

This addition allows users to include OCI Generative AI in their LLM benchmark suites alongside other providers, improving coverage and flexibility in performance evaluations.
