| # 🚅 litellm | |
| A light 100 line package to simplify calling OpenAI, Azure, Cohere, Anthropic APIs | |
| ###### litellm manages: | |
| * Calling all LLM APIs using the OpenAI format - `completion(model, messages)` | |
| * Consistent output for all LLM APIs, text responses will always be available at `['choices'][0]['message']['content']` | |
| * Consistent Exceptions for all LLM APIs, we map RateLimit, Context Window, and Authentication Error exceptions across all providers to their OpenAI equivalents. [see Code](https://github.com/BerriAI/litellm/blob/ba1079ff6698ef238c5c7f771dd2b698ec76f8d9/litellm/utils.py#L250) | |
| ###### observability: | |
| * Logging - see exactly what the raw model request/response is by plugging in your own function `completion(.., logger_fn=your_logging_fn)` and/or print statements from the package `litellm.set_verbose=True` | |
| * Callbacks - automatically send your data to Helicone, Sentry, Posthog, Slack - `litellm.success_callbacks`, `litellm.failure_callbacks` [see Callbacks](https://litellm.readthedocs.io/en/latest/advanced/) | |
| ## Quick Start | |

| pip install litellm | |
| ``` | |
| ### Usage | |
| ```python | |
| from litellm import completion | |
| ## set ENV variables | |
| os.environ["OPENAI_API_KEY"] = "openai key" | |
| os.environ["COHERE_API_KEY"] = "cohere key" | |
| messages = [{ "content": "Hello, how are you?","role": "user"}] | |
| # openai call | |
| response = completion(model="gpt-3.5-turbo", messages=messages) | |
| # cohere call | |
| response = completion("command-nightly", messages) | |
| ``` | |

| ## Why did we build liteLLM | |
| - **Need for simplicity**: Our code started to get extremely complicated managing & translating calls between Azure, OpenAI, Cohere | |
