Complete List: Check the Swagger UI docs on <your-proxy-url>/#/config.yaml (e.g. http://0.0.0.0:4000/#/config.yaml), for everything you can pass in the config.yaml.

Quick Start

Set a model alias for your deployments.

In the config.yaml the model_name parameter is the user-facing name to use for your deployment.

In the config below:

model_name: the name to pass TO litellm from the external client
litellm_params.model: the model string passed to the litellm.completion() function

E.g.:

model=vllm-models will route to openai/facebook/opt-125m.
model=gpt-3.5-turbo will load balance between azure/gpt-turbo-small-eu and azure/gpt-turbo-small-ca

model_list:

Step 2: Start Proxy with config

$ litellm --config /path/to/config.yaml

tip

Run with --detailed_debug if you need detailed debug logs

$ litellm --config /path/to/config.yaml --detailed_debug

Step 3: Test it

Sends request to model where model_name=gpt-3.5-turbo on config.yaml.

If multiple with model_name=gpt-3.5-turbo does Load Balancing

Langchain, OpenAI SDK Usage Examples

curl --location 'http://0.0.0.0:4000/chat/completions' \
--header 'Content-Type: application/json' \
--data ' {
      "model": "gpt-3.5-turbo",
      "messages": [
        {
          "role": "user",
          "content": "what llm are you"
        }
      ],
    }
'

LLM configs `model_list`

Model-specific params (API Base, Keys, Temperature, Max Tokens, Organization, Headers etc.)

You can use the config to save model-specific information like api_base, api_key, temperature, max_tokens, etc.

All input params

Step 1: Create a config.yaml file

model_list:
  - model_name: gpt-4-team1
    litellm_params: # params for litellm.completion() - https://docs.litellm.ai/docs/completion/input#input---request-body
      model: azure/chatgpt-v-2
      api_base: https://openai-gpt-4-test-v-1.openai.azure.com/
      api_version: "2023-05-15"
      azure_ad_token: eyJ0eXAiOiJ
      seed: 12
      max_tokens: 20
  - model_name: gpt-4-team2
    litellm_params:
      model: azure/gpt-4
      api_key: sk-123
      api_base: https://openai-gpt-4-test-v-2.openai.azure.com/
      temperature: 0.2
  - model_name: openai-gpt-3.5
    litellm_params:
      model: openai/gpt-3.5-turbo
      extra_headers: {"AI-Resource Group": "ishaan-resource"}
      api_key: sk-123
      organization: org-ikDc4ex8NB
      temperature: 0.2
  - model_name: mistral-7b
    litellm_params:
      model: ollama/mistral
      api_base: your_ollama_api_base

Step 2: Start server with config

$ litellm --config /path/to/config.yaml

Expected Logs:

Look for this line in your console logs to confirm the config.yaml was loaded in correctly.

LiteLLM: Proxy initialized with Config, Set models:

Embedding Models - Use Sagemaker, Bedrock, Azure, OpenAI, XInference

See supported Embedding Providers & Models here

model_list:
  - model_name: bedrock-cohere
    litellm_params:
      model: "bedrock/cohere.command-text-v14"
      aws_region_name: "us-west-2"
  - model_name: bedrock-cohere
    litellm_params:
      model: "bedrock/cohere.command-text-v14"
      aws_region_name: "us-east-2"
  - model_name: bedrock-cohere
    litellm_params:
      model: "bedrock/cohere.command-text-v14"
      aws_region_name: "us-east-1"

Here's how to route between GPT-J embedding (sagemaker endpoint), Amazon Titan embedding (Bedrock) and Azure OpenAI embedding on the proxy server:

model_list:
  - model_name: sagemaker-embeddings
    litellm_params: 
      model: "sagemaker/berri-benchmarking-gpt-j-6b-fp16"
  - model_name: amazon-embeddings
    litellm_params:
      model: "bedrock/amazon.titan-embed-text-v1"
  - model_name: azure-embeddings
    litellm_params: 
      model: "azure/azure-embedding-model"
      api_base: "os.environ/AZURE_API_BASE" # os.getenv("AZURE_API_BASE")
      api_key: "os.environ/AZURE_API_KEY" # os.getenv("AZURE_API_KEY")
      api_version: "2023-07-01-preview"

general_settings:
  master_key: sk-1234 # [OPTIONAL] if set all calls to proxy will require either this key or a valid generated token

LiteLLM Proxy supports all Feature-Extraction Embedding models.

model_list:
  - model_name: deployed-codebert-base
    litellm_params: 
      # send request to deployed hugging face inference endpoint
      model: huggingface/microsoft/codebert-base # add huggingface prefix so it routes to hugging face
      api_key: hf_LdS                            # api key for hugging face inference endpoint
      api_base: https://uysneno1wv2wd4lw.us-east-1.aws.endpoints.huggingface.cloud # your hf inference endpoint 
  - model_name: codebert-base
    litellm_params: 
      # no api_base set, sends request to hugging face free inference api https://api-inference.huggingface.co/models/
      model: huggingface/microsoft/codebert-base # add huggingface prefix so it routes to hugging face
      api_key: hf_LdS                            # api key for hugging face                     

model_list:
  - model_name: azure-embedding-model # model group
    litellm_params:
      model: azure/azure-embedding-model # model name for litellm.embedding(model=azure/azure-embedding-model) call
      api_base: your-azure-api-base
      api_key: your-api-key
      api_version: 2023-07-01-preview

model_list:
- model_name: text-embedding-ada-002 # model group
  litellm_params:
    model: text-embedding-ada-002 # model name for litellm.embedding(model=text-embedding-ada-002) 
    api_key: your-api-key-1
- model_name: text-embedding-ada-002 
  litellm_params:
    model: text-embedding-ada-002
    api_key: your-api-key-2

https://docs.litellm.ai/docs/providers/xinference

Note add xinference/ prefix to litellm_params: model so litellm knows to route to OpenAI

model_list:
- model_name: embedding-model  # model group
  litellm_params:
    model: xinference/bge-base-en   # model name for litellm.embedding(model=xinference/bge-base-en) 
    api_base: http://0.0.0.0:9997/v1

Use this for calling /embedding endpoints on OpenAI Compatible Servers.

Note add openai/ prefix to litellm_params: model so litellm knows to route to OpenAI

model_list:
- model_name: text-embedding-ada-002  # model group
  litellm_params:
    model: openai/<your-model-name>   # model name for litellm.embedding(model=text-embedding-ada-002) 
    api_base: <model-api-base>

Start Proxy

litellm --config config.yaml

Make Request

Sends Request to bedrock-cohere

curl --location 'http://0.0.0.0:4000/chat/completions' \
  --header 'Content-Type: application/json' \
  --data ' {
  "model": "bedrock-cohere",
  "messages": [
      {
      "role": "user",
      "content": "gm"
      }
  ]
}'

Multiple OpenAI Organizations

Add all openai models across all OpenAI organizations with just 1 model definition

  - model_name: *
    litellm_params:
      model: openai/*
      api_key: os.environ/OPENAI_API_KEY
      organization:
       - org-1 
       - org-2 
       - org-3

LiteLLM will automatically create separate deployments for each org.

Confirm this via

curl --location 'http://0.0.0.0:4000/v1/model/info' \
--header 'Authorization: Bearer ${LITELLM_KEY}' \
--data ''

Provider specific wildcard routing

Proxy all models from a provider

Use this if you want to proxy all models from a specific provider without defining them on the config.yaml

Step 1 - define provider specific routing on config.yaml

model_list:
  # provider specific wildcard routing
  - model_name: "anthropic/*"
    litellm_params:
      model: "anthropic/*"
      api_key: os.environ/ANTHROPIC_API_KEY
  - model_name: "groq/*"
    litellm_params:
      model: "groq/*"
      api_key: os.environ/GROQ_API_KEY
  - model_name: "fo::*:static::*" # all requests matching this pattern will be routed to this deployment, example: model="fo::hi::static::hi" will be routed to deployment: "openai/fo::*:static::*"
    litellm_params:
      model: "openai/fo::*:static::*"
      api_key: os.environ/OPENAI_API_KEY

Step 2 - Run litellm proxy

$ litellm --config /path/to/config.yaml

Step 3 Test it

Test with anthropic/ - all models with anthropic/ prefix will get routed to anthropic/*

curl http://localhost:4000/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer sk-1234" \
  -d '{
    "model": "anthropic/claude-3-sonnet-20240229",
    "messages": [
      {"role": "user", "content": "Hello, Claude!"}
    ]
  }'

Test with groq/ - all models with groq/ prefix will get routed to groq/*

curl http://localhost:4000/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer sk-1234" \
  -d '{
    "model": "groq/llama3-8b-8192",
    "messages": [
      {"role": "user", "content": "Hello, Claude!"}
    ]
  }'

Test with fo::*::static::* - all requests matching this pattern will be routed to openai/fo::*:static::*

curl http://localhost:4000/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer sk-1234" \
  -d '{
    "model": "fo::hi::static::hi",
    "messages": [
      {"role": "user", "content": "Hello, Claude!"}
    ]
  }'

Load Balancing

info

For more on this, go to this page

Use this to call multiple instances of the same model and configure things like routing strategy.

For optimal performance:

Set tpm/rpm per model deployment. Weighted picks are then based on the established tpm/rpm.
Select your optimal routing strategy in router_settings:routing_strategy.

LiteLLM supports

["simple-shuffle", "least-busy", "usage-based-routing","latency-based-routing"], default="simple-shuffle"`

When tpm/rpm is set + routing_strategy==simple-shuffle litellm will use a weighted pick based on set tpm/rpm. In our load tests setting tpm/rpm for all deployments + routing_strategy==simple-shuffle maximized throughput

When using multiple LiteLLM Servers / Kubernetes set redis settings router_settings:redis_host etc

model_list:
  - model_name: zephyr-beta

Load API Keys / config values from Environment

If you have secrets saved in your environment, and don't want to expose them in the config.yaml, here's how to load model-specific keys from the environment. This works for ANY value on the config.yaml

os.environ/<YOUR-ENV-VAR> # runs os.getenv("YOUR-ENV-VAR")

model_list:
  - model_name: gpt-4-team1
    litellm_params: # params for litellm.completion() - https://docs.litellm.ai/docs/completion/input#input---request-body
      model: azure/chatgpt-v-2
      api_base: https://openai-gpt-4-test-v-1.openai.azure.com/
      api_version: "2023-05-15"
      api_key: os.environ/AZURE_NORTH_AMERICA_API_KEY # 👈 KEY CHANGE

See Code

s/o to @David Manouchehri for helping with this.

Load API Keys from Secret Managers (Azure Vault, etc)

Using Secret Managers with LiteLLM Proxy

Set Supported Environments for a model - `production`, `staging`, `development`

Use this if you want to control which model is exposed on a specific litellm environment

Supported Environments:

production
staging
development

Set LITELLM_ENVIRONMENT="<environment>" in your environment. Can be one of production, staging or development

For each model set the list of supported environments in model_info.supported_environments

model_list:
 - model_name: gpt-3.5-turbo
   litellm_params:
     model: openai/gpt-3.5-turbo
     api_key: os.environ/OPENAI_API_KEY
   model_info:
     supported_environments: ["development", "production", "staging"]
 - model_name: gpt-4
   litellm_params:
     model: openai/gpt-4
     api_key: os.environ/OPENAI_API_KEY
   model_info:
     supported_environments: ["production", "staging"]
 - model_name: gpt-4o
   litellm_params:
     model: openai/gpt-4o
     api_key: os.environ/OPENAI_API_KEY
   model_info:
     supported_environments: ["production"]

Set Custom Prompt Templates

LiteLLM by default checks if a model has a prompt template and applies it (e.g. if a huggingface model has a saved chat template in it's tokenizer_config.json). However, you can also set a custom prompt template on your proxy in the config.yaml:

Step 1: Save your prompt template in a config.yaml

# Model-specific parameters
model_list:
  - model_name: mistral-7b # model alias
    litellm_params: # actual params for litellm.completion()
      model: "huggingface/mistralai/Mistral-7B-Instruct-v0.1" 
      api_base: "<your-api-base>"
      api_key: "<your-api-key>" # [OPTIONAL] for hf inference endpoints
      initial_prompt_value: "\n"
      roles: {"system":{"pre_message":"<|im_start|>system\n", "post_message":"<|im_end|>"}, "assistant":{"pre_message":"<|im_start|>assistant\n","post_message":"<|im_end|>"}, "user":{"pre_message":"<|im_start|>user\n","post_message":"<|im_end|>"}}
      final_prompt_value: "\n"
      bos_token: " "
      eos_token: " "
      max_tokens: 4096

Step 2: Start server with config

$ litellm --config /path/to/config.yaml

General Settings `general_settings` (DB Connection, etc)

Configure DB Pool Limits + Connection Timeouts

general_settings:

Extras

Disable Swagger UI

To disable the Swagger docs from the base url, set

NO_DOCS="True"

in your environment, and restart the proxy.

Use CONFIG_FILE_PATH for proxy (Easier Azure container deployment)

Setup config.yaml

model_list:
  - model_name: gpt-3.5-turbo
    litellm_params:
      model: gpt-3.5-turbo
      api_key: os.environ/OPENAI_API_KEY

Store filepath as env var

CONFIG_FILE_PATH="/path/to/config.yaml"

Start Proxy

$ litellm 

# RUNNING on http://0.0.0.0:4000

Providing LiteLLM config.yaml file as a s3, GCS Bucket Object/url

Use this if you cannot mount a config file on your deployment service (example - AWS Fargate, Railway etc)

LiteLLM Proxy will read your config.yaml from an s3 Bucket or GCS Bucket

GCS Bucket
s3

Set the following .env vars

LITELLM_CONFIG_BUCKET_TYPE = "gcs"                              # set this to "gcs"         
LITELLM_CONFIG_BUCKET_NAME = "litellm-proxy"                    # your bucket name on GCS
LITELLM_CONFIG_BUCKET_OBJECT_KEY = "proxy_config.yaml"         # object key on GCS

Start litellm proxy with these env vars - litellm will read your config from GCS

docker run --name litellm-proxy \
   -e DATABASE_URL=<database_url> \
   -e LITELLM_CONFIG_BUCKET_NAME=<bucket_name> \
   -e LITELLM_CONFIG_BUCKET_OBJECT_KEY="<object_key>> \
   -e LITELLM_CONFIG_BUCKET_TYPE="gcs" \
   -p 4000:4000 \
