When does this happen?

IF Multiple LLM providers have different SDKs, authentication patterns, and request formats, causing integration friction.

How others solved it

THEN Use LiteLLM as an open-source AI Gateway that provides a single, unified interface via the OpenAI format. Install the Python SDK and call any LLM by specifying a provider/model prefix (e.g., openai/gpt-4o or anthropic/claude-sonnet-4-20250514). This eliminates the need to manage multiple provider-specific SDKs and simplifies switching or fallback.

from litellm import completion; response = completion(model='openai/gpt-4o', messages=[{'role':'user','content':'Hello'}]); # or for Anthropic: model='anthropic/claude-sonnet-4-20250514'
