[FEATURE] Native Oracle Cloud (OCI) Generative AI Integration

[fede-kamel]

Feature Request

Add native support for Oracle Cloud Infrastructure (OCI) Generative AI as a first-class provider in CrewAI.

Why

OCI GenAI is one of the few cloud platforms hosting multiple model families under one roof — Meta Llama, Google Gemini, OpenAI GPT (4o, 5, OSS), xAI Grok, and Cohere — all accessible through a single API surface. Enterprise teams on OCI currently have no native path to use these models with CrewAI without custom workarounds.

Adding native OCI support would:

• Give CrewAI access to Oracle's enterprise customer base
• Enable crews to use 50+ models across 6 model families on OCI
• Support embeddings (Cohere models) for RAG workflows
• Support tool/function calling for agentic workflows
• Provide an alternative to OpenAI/Anthropic for enterprises with Oracle cloud commitments

Implementation

PR #4885 provides a complete implementation including:

• OciLLM class with chat, streaming, and tool calling
• OciEmbedding class for Cohere embedding models
• OCI API key authentication with request signing
• Model-specific parameter handling across all families
• Full test coverage
