SAP Cloud SDK for AI (Python)

Package rename: The PyPI package generative-ai-hub-sdk is deprecated (v4.12.4 is the last release). Its successor is sap-ai-sdk-gen (currently v6.10.0 per public PyPI registry evidence from 2026-06-15). Code and tutorials referencing generative-ai-hub-sdk should migrate to sap-ai-sdk-gen; the import name remains gen_ai_hub.

The official Python SDK for SAP Generative AI Hub and Orchestration Service. It wraps the native SDKs of model providers (OpenAI, Amazon Bedrock, Google GenAI) and offers a harmonised LangChain integration and a full Orchestration client — all routed through SAP AI Core with unified authentication. Package freshness is registry-verified; AI Core runtime behavior and exact model availability still require target-tenant validation.

When to Use This Skill

Use this skill when:

• Building Python applications that call LLMs through SAP AI Core / Generative AI Hub
• Using the gen_ai_hub Python package (installed as sap-ai-sdk-gen)
• Integrating OpenAI, Amazon Bedrock, or Google GenAI models via SAP's proxy
• Implementing LangChain chains with SAP AI Core as the backend
• Using the Orchestration Service from Python (templating, filtering, masking, grounding)
• Migrating code from the deprecated generative-ai-hub-sdk to sap-ai-sdk-gen
• Generating embeddings through SAP AI Core
• Working with SAP RPT-1 (Relational Pretrained Transformer) for tabular predictions

Quick Start

Native OpenAI Chat Completion

from gen_ai_hub.proxy.native.openai import chat

messages = [
    {"role": "system", "content": "You are a helpful assistant."},
    {"role": "user", "content": "What is SAP BTP?"}
]

response = chat.completions.create(
    model_name="gpt-4o-mini",
    messages=messages
)
print(response.choices[0].message.content)

Orchestration Service

from gen_ai_hub.orchestration_v2 import (
    OrchestrationConfig, OrchestrationService,
    ModuleConfig, PromptTemplatingModuleConfig,
    Template, UserMessage, LLMModelDetails
)

config = OrchestrationConfig(
    modules=ModuleConfig(
        prompt_templating=PromptTemplatingModuleConfig(
            prompt=Template(
                template=[UserMessage(role="user", content="{{?question}}")]
            ),
            model=LLMModelDetails(name="gpt-4o-mini")
        )
    )
)

service = OrchestrationService(config=config)
response = service.run(placeholder_values={"question": "What is SAP?"})
print(response.final_result.choices[0].message.content)

Installation

# All providers + LangChain support
pip install "sap-ai-sdk-gen[all]"

# Default (OpenAI only, no LangChain)
pip install sap-ai-sdk-gen

# Specific providers (without LangChain)
pip install "sap-ai-sdk-gen[google, amazon]"

Authentication

The SDK reads credentials via AICoreV2Client.from_env(), which resolves credentials in this order:

1. Keyword arguments passed to GenAIHubProxyClient(...)
2. Environment variables — AICORE_CLIENT_ID, AICORE_CLIENT_SECRET, AICORE_AUTH_URL, AICORE_BASE_URL, AICORE_RESOURCE_GROUP
3. Config file — $AICORE_HOME/config.json (or path set by AICORE_CONFIG); use AICORE_PROFILE to select a named profile
4. VCAP_SERVICES — automatic on Cloud Foundry/Kyma when the AI Core service is bound

Local Development (Environment Variables)
