ReqLLM.Providers.GoogleVertex.OpenAICompat (ReqLLM v1.14.0)

OpenAI-compatible model family support for Google Vertex AI.

Handles third-party MaaS (Model-as-a-Service) models on Vertex AI that use the OpenAI Chat Completions API format.

Currently supports:

GLM models (zai-org/glm-4.7-maas)
OpenAI OSS models (openai/gpt-oss-120b-maas, openai/gpt-oss-20b-maas)
Other future MaaS models using OpenAI-compatible format

These models are accessed via Vertex AI's endpoints/openapi/chat/completions endpoint and use standard OpenAI Chat Completions request/response format. The model ID (e.g., zai-org/glm-4.7-maas) is included in the request body.
