LiteLLM manages:
|
||
- Translate inputs to provider's `completion` and `embedding` endpoints
|
||
- [Consistent output](https://docs.litellm.ai/docs/completion/output), text responses will always be available at `['choices'][0]['message']['content']`
|
||
- Load-balance multiple deployments (e.g. Azure/OpenAI) - `Router` **1k+ requests/second**

# Usage ([**Docs**](https://docs.litellm.ai/docs/))
|
||
> [!IMPORTANT]
|
||
> LiteLLM v1.0.0 now requires `openai>=1.0.0`. Migration guide [here](https://docs.litellm.ai/docs/migration)

</a>
|
||
|
||
|
||
```shell
|
||
pip install litellm
|
||
```
|
||
|
||
```python
|
||
from litellm import completion
|
||
import os
|
||
|
||
## set ENV variables
|
||
os.environ["OPENAI_API_KEY"] = "your-openai-key"
|
||
os.environ["COHERE_API_KEY"] = "your-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(model="command-nightly", messages=messages)
|
||
print(response)
|
||
```
|
||
|
||
## Async ([Docs](https://docs.litellm.ai/docs/completion/stream#async-completion))
|
||
|
||
```python
|
||
from litellm import acompletion
|
||
import asyncio
|
||
|
||
async def test_get_response():
|
||
user_message = "Hello, how are you?"
|
||
messages = [{"content": user_message, "role": "user"}]
|
||
response = await acompletion(model="gpt-3.5-turbo", messages=messages)
|
||
return response
|
||
|
||
response = asyncio.run(test_get_response())
|
||
print(response)
|
||
```
|
||
|
||
## Streaming ([Docs](https://docs.litellm.ai/docs/completion/stream))
|
||
liteLLM supports streaming the model response back, pass `stream=True` to get a streaming iterator in response.
|
||
Streaming is supported for all models (Bedrock, Huggingface, TogetherAI, Azure, OpenAI, etc.)
|
||
```python
|
||
from litellm import completion
|
||
response = completion(model="gpt-3.5-turbo", messages=messages, stream=True)
|
||
for part in response:
|
||
print(part.choices[0].delta.content or "")
|
||
|
||
# claude 2
|
||
response = completion('claude-2', messages, stream=True)
|
||
for part in response:
|
||
print(part.choices[0].delta.content or "")
|
||
```
|
||
|
||
## Logging Observability ([Docs](https://docs.litellm.ai/docs/observability/callbacks))
|
||
LiteLLM exposes pre defined callbacks to send data to Langfuse, LLMonitor, Helicone, Promptlayer, Traceloop, Slack
|
||
```python
|
||
from litellm import completion
|
||
|
||
## set env variables for logging tools
|
||
os.environ["LANGFUSE_PUBLIC_KEY"] = ""
|
||
os.environ["LANGFUSE_SECRET_KEY"] = ""
|
||
os.environ["LLMONITOR_APP_ID"] = "your-llmonitor-app-id"
|
||
|
||
os.environ["OPENAI_API_KEY"]
|
||
|
||
# set callbacks
|
||
litellm.success_callback = ["langfuse", "llmonitor"] # log input/output to langfuse, llmonitor, supabase
|
||
|
||
#openai call
|
||
response = completion(model="gpt-3.5-turbo", messages=[{"role": "user", "content": "Hi 👋 - i'm openai"}])
|
||
```

# OpenAI Proxy - ([Docs](https://docs.litellm.ai/docs/simple_proxy))
|
||
|
||
Track spend across multiple projects/people
|
||
|
||
## 📖 Proxy Endpoints - [Swagger Docs](https://litellm-api.up.railway.app/)
|
||
|
||
## Quick Start Proxy - CLI
|
||
|
||
```shell
|
||
pip install litellm[proxy]
|
||
```
|
||
|
||
### Step 1: Start litellm proxy
|
||
```shell
|
||
$ litellm --model huggingface/bigcode/starcoder
|
||
|
||
#INFO: Proxy running on http://0.0.0.0:8000
|
||
```
|
||
|
||
### Step 2: Make ChatCompletions Request to Proxy
|
||
```python
|
||
import openai # openai v1.0.0+
|
||
client = openai.OpenAI(api_key="anything",base_url="http://0.0.0.0:8000") # set proxy to base_url
|
||
# request sent to model set on litellm proxy, `litellm --model`
|
||
response = client.chat.completions.create(model="gpt-3.5-turbo", messages = [
|
||
{
|
||
"role": "user",
|
||
"content": "this is a test request, write a short poem"
|
||
}
|
||
])
|
||
|
||
print(response)
|
||
```
|
||
|
||
## Proxy Key Management ([Docs](https://docs.litellm.ai/docs/proxy/virtual_keys))
|
||
Track Spend, Set budgets and create virtual keys for the proxy
|
||
`POST /key/generate`
|
||
|
||
### Request
|
||
```shell
|
||
curl 'http://0.0.0.0:8000/key/generate' \
|
||
--header 'Authorization: Bearer sk-1234' \
|
||
--header 'Content-Type: application/json' \
|
||
--data-raw '{"models": ["gpt-3.5-turbo", "gpt-4", "claude-2"], "duration": "20m","metadata": {"user": "ishaan@berri.ai", "team": "core-infra"}}'
|
||
```
|
||
|
||
### Expected Response
|
||
```shell
|
||
{
|
||
"key": "sk-kdEXbIqZRwEeEiHwdg7sFA", # Bearer token
|
||
"expires": "2023-11-19T01:38:25.838000+00:00" # datetime object
|
||
}
|
||
```
|
||
|
||
