💰 Budgets, Rate Limits
Requirements:
Set Budgets
You can set budgets at 3 levels:
- For the proxy
- For a user
- For a 'user' passed to
/chat/completions
,/embeddings
etc - For a key
- For a key (model specific budgets)
- For Proxy
- For User
- For Team
- For 'user' passed to /chat/completions
- For Key
- For Key (model specific)
Apply a budget across all calls on the proxy
Step 1. Modify config.yaml
general_settings:
master_key: sk-1234
litellm_settings:
# other litellm settings
max_budget: 0 # (float) sets max budget as $0 USD
budget_duration: 30d # (str) frequency of reset - You can set duration as seconds ("30s"), minutes ("30m"), hours ("30h"), days ("30d").
Step 2. Start proxy
litellm /path/to/config.yaml
Step 3. Send test call
curl --location 'http://0.0.0.0:4000/chat/completions' \
--header 'Autherization: Bearer sk-1234' \
--header 'Content-Type: application/json' \
--data '{
"model": "gpt-3.5-turbo",
"messages": [
{
"role": "user",
"content": "what llm are you"
}
],
}'
Apply a budget across multiple keys.
LiteLLM exposes a /user/new
endpoint to create budgets for this.
You can:
By default the max_budget
is set to null
and is not checked for keys
Add budgets to users
curl --location 'http://localhost:4000/user/new' \
--header 'Authorization: Bearer <your-master-key>' \
--header 'Content-Type: application/json' \
--data-raw '{"models": ["azure-models"], "max_budget": 0, "user_id": "krrish3@berri.ai"}'
Sample Response
{
"key": "sk-YF2OxDbrgd1y2KgwxmEA2w",
"expires": "2023-12-22T09:53:13.861000Z",
"user_id": "krrish3@berri.ai",
"max_budget": 0.0
}
Add budget duration to users
budget_duration
: Budget is reset at the end of specified duration. If not set, budget is never reset. You can set duration as seconds ("30s"), minutes ("30m"), hours ("30h"), days ("30d").
curl 'http://0.0.0.0:4000/user/new' \
--header 'Authorization: Bearer <your-master-key>' \
--header 'Content-Type: application/json' \
--data-raw '{
"team_id": "core-infra", # [OPTIONAL]
"max_budget": 10,
"budget_duration": 10s,
}'
Create new keys for existing user
Now you can just call /key/generate
with that user_id (i.e. krrish3@berri.ai) and:
- Budget Check: krrish3@berri.ai's budget (i.e. $10) will be checked for this key
- Spend Tracking: spend for this key will update krrish3@berri.ai's spend as well
curl --location 'http://0.0.0.0:4000/key/generate' \
--header 'Authorization: Bearer <your-master-key>' \
--header 'Content-Type: application/json' \
--data '{"models": ["azure-models"], "user_id": "krrish3@berri.ai"}'
Add budgets to users
curl --location 'http://localhost:4000/team/new' \
--header 'Authorization: Bearer <your-master-key>' \
--header 'Content-Type: application/json' \
--data-raw '{
"team_alias": "my-new-team_4",
"members_with_roles": [{"role": "admin", "user_id": "5c4a0aa3-a1e1-43dc-bd87-3c2da8382a3a"}],
"rpm_limit": 99
}'
Sample Response
{
"team_alias": "my-new-team_4",
"team_id": "13e83b19-f851-43fe-8e93-f96e21033100",
"admins": [],
"members": [],
"members_with_roles": [
{
"role": "admin",
"user_id": "5c4a0aa3-a1e1-43dc-bd87-3c2da8382a3a"
}
],
"metadata": {},
"tpm_limit": null,
"rpm_limit": 99,
"max_budget": null,
"models": [],
"spend": 0.0,
"max_parallel_requests": null,
"budget_duration": null,
"budget_reset_at": null
}
Use this to budget user
passed to /chat/completions
, without needing to create a key for every user
Step 1. Modify config.yaml
Define litellm.max_user_budget
general_settings:
master_key: sk-1234
litellm_settings:
max_budget: 10 # global budget for proxy
max_user_budget: 0.0001 # budget for 'user' passed to /chat/completions
- Make a /chat/completions call, pass 'user' - First call Works
curl --location 'http://0.0.0.0:4000/chat/completions' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer sk-zi5onDRdHGD24v0Zdn7VBA' \
--data ' {
"model": "azure-gpt-3.5",
"user": "ishaan3",
"messages": [
{
"role": "user",
"content": "what time is it"
}
]
}'
- Make a /chat/completions call, pass 'user' - Call Fails, since 'ishaan3' over budget
curl --location 'http://0.0.0.0:4000/chat/completions' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer sk-zi5onDRdHGD24v0Zdn7VBA' \
--data ' {
"model": "azure-gpt-3.5",
"user": "ishaan3",
"messages": [
{
"role": "user",
"content": "what time is it"
}
]
}'
Error
{"error":{"message":"Authentication Error, ExceededBudget: User ishaan3 has exceeded their budget. Current spend: 0.0008869999999999999; Max Budget: 0.0001","type":"auth_error","param":"None","code":401}}%
Apply a budget on a key.
You can:
Expected Behaviour
- Costs Per key get auto-populated in
LiteLLM_VerificationToken
Table - After the key crosses it's
max_budget
, requests fail - If duration set, spend is reset at the end of the duration
By default the max_budget
is set to null
and is not checked for keys
Add budgets to keys
curl 'http://0.0.0.0:4000/key/generate' \
--header 'Authorization: Bearer <your-master-key>' \
--header 'Content-Type: application/json' \
--data-raw '{
"team_id": "core-infra", # [OPTIONAL]
"max_budget": 10,
}'
Example Request to /chat/completions
when key has crossed budget
curl --location 'http://0.0.0.0:4000/chat/completions' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer <generated-key>' \
--data ' {
"model": "azure-gpt-3.5",
"user": "e09b4da8-ed80-4b05-ac93-e16d9eb56fca",
"messages": [
{
"role": "user",
"content": "respond in 50 lines"
}
],
}'
Expected Response from /chat/completions
when key has crossed budget
{
"detail":"Authentication Error, ExceededTokenBudget: Current spend for token: 7.2e-05; Max Budget for Token: 2e-07"
}
Add budget duration to keys
budget_duration
: Budget is reset at the end of specified duration. If not set, budget is never reset. You can set duration as seconds ("30s"), minutes ("30m"), hours ("30h"), days ("30d").
curl 'http://0.0.0.0:4000/key/generate' \
--header 'Authorization: Bearer <your-master-key>' \
--header 'Content-Type: application/json' \
--data-raw '{
"team_id": "core-infra", # [OPTIONAL]
"max_budget": 10,
"budget_duration": 10s,
}'
Apply model specific budgets on a key.
Expected Behaviour
model_spend
gets auto-populated inLiteLLM_VerificationToken
Table- After the key crosses the budget set for the
model
inmodel_max_budget
, calls fail
By default the model_max_budget
is set to {}
and is not checked for keys
- LiteLLM will track the cost/budgets for the
model
passed to LLM endpoints (/chat/completions
,/embeddings
)
Add model specific budgets to keys
curl 'http://0.0.0.0:4000/key/generate' \
--header 'Authorization: Bearer <your-master-key>' \
--header 'Content-Type: application/json' \
--data-raw '{
model_max_budget={"gpt4": 0.5, "gpt-5": 0.01}
}'
Set Rate Limits
You can set:
- tpm limits (tokens per minute)
- rpm limits (requests per minute)
- max parallel requests
- Per User
- Per Key
Use /user/new
, to persist rate limits across multiple keys.
curl --location 'http://0.0.0.0:4000/user/new' \
--header 'Authorization: Bearer sk-1234' \
--header 'Content-Type: application/json' \
--data '{"user_id": "krrish@berri.ai", "max_parallel_requests": 10, "tpm_limit": 20, "rpm_limit": 4}'
Expected Response
{
"key": "sk-sA7VDkyhlQ7m8Gt77Mbt3Q",
"expires": "2024-01-19T01:21:12.816168",
"user_id": "krrish@berri.ai",
}
Use /key/generate
, if you want them for just that key.
curl --location 'http://0.0.0.0:4000/key/generate' \
--header 'Authorization: Bearer sk-1234' \
--header 'Content-Type: application/json' \
--data '{"max_parallel_requests": 10, "tpm_limit": 20, "rpm_limit": 4}'
Expected Response
{
"key": "sk-ulGNRXWtv7M0lFnnsQk0wQ",
"expires": "2024-01-18T20:48:44.297973",
"user_id": "78c2c8fc-c233-43b9-b0c3-eb931da27b84" // 👈 auto-generated
}
Grant Access to new model
Use model access groups to give users access to select models, and add new ones to it over time (e.g. mistral, llama-2, etc.).
Difference between doing this with /key/generate
vs. /user/new
? If you do it on /user/new
it'll persist across multiple keys generated for that user.
Step 1. Assign model, access group in config.yaml
model_list:
- model_name: text-embedding-ada-002
litellm_params:
model: azure/azure-embedding-model
api_base: "os.environ/AZURE_API_BASE"
api_key: "os.environ/AZURE_API_KEY"
api_version: "2023-07-01-preview"
model_info:
access_groups: ["beta-models"] # 👈 Model Access Group
Step 2. Create key with access group
curl --location 'http://localhost:4000/user/new' \
-H 'Authorization: Bearer <your-master-key>' \
-H 'Content-Type: application/json' \
-d '{"models": ["beta-models"], # 👈 Model Access Group
"max_budget": 0}'
Create new keys for existing user
Just include user_id in the /key/generate
request.
curl --location 'http://0.0.0.0:4000/key/generate' \
--header 'Authorization: Bearer <your-master-key>' \
--header 'Content-Type: application/json' \
--data '{"models": ["azure-models"], "user_id": "krrish@berri.ai"}'
