[FEATURE] Add SAP BTP GenAI Hub model provider support

[ashivadi]

Problem Statement

Feature Request: SAP BTP GenAI Hub Model Provider

Problem Statement

SAP customers using SAP BTP with GenAI Hub currently use Strands Agents with their SAP-hosted models using DIY approach provided here. SAP GenAI Hub provides access to foundation models (Nova, Claude, Titan) via Bedrock through SAP's AI Core infrastructure.

Proposed Solution

Add a new official model provider SAPGenAIHubModel that integrates with SAP BTP GenAI Hub.

pip install strands-agents 'sap-ai-sdk-gen[all]' strands-agents-tools

from strands import Agent
from strands.models.sap_genai_hub import SAPGenAIHubModel
from strands_tools import calculator

# Initialize SAP GenAI Hub model (requires ~/.aicore/config.json with credentials)
model = SAPGenAIHubModel(
    model_id="amazon--nova-lite",  # or see available models below
    temperature=0.7,
    max_tokens=1000,
    top_p=0.9
)

agent = Agent(model=model, tools=[calculator])
response = agent("What is 2+2?")
print(response.message)

Benefits

• Enables SAP customers to use Strands Agents with their SAP BTP infrastructure
• Extends Strands' reach to SAP ecosystem
• Follows existing patterns from Bedrock model provider

Proposed Solution

#1263

Use Case

Allow users to build with strands agents sdk while consuming tokens from Bedrock via SAP GenAI hub as shown in examples here: https://github.com/aws-samples/sample-sap-genai-hub-bedrock/blob/main/04-strands-agent-with-sap-genai-hub.ipynb

Alternatives Solutions

Users can clone the custom class repo and manually import in their projects, but this approach will help it officially install via strands
