RateLimiting

RateLimiting configuration allows you to rate limit requests to a specified tokens/requests per minute/hour/day for certain sets of requests. The rate limiting configuration contains an array of rules. Every request is evaluated against the set of rules, and only the first matching rule is applied—subsequent rules are ignored. So keep generic ones at bottom, specialised configs at top.

For each rule, we have three sections:

when
1. subjects: An array of user, teams or service accounts from which requests is originated - for e.g. user:[email protected], team:team1, serviceaccount:serviceaccountname
2. models: An array of model ids which will be used to filter the requests. The model ids are the same as what we pass in the model field in the request.
3. metadata.
limit_to: Integer value which along with unit specifies the limit (for e.g. 100000 tokens per minute)
unit: Possible values are requests_per_minute, requests_per_hour, requests_per_day, tokens_per_minute, tokens_per_hour, tokens_per_day

An example of a rate limiting config is as follows:

name: ratelimiting-config
type: gateway-rate-limiting-config
# The rules are evaluated in order, and all matching rules are considered.
# If any one of them causes a rate limit, the corresponding ID will be returned.
rules:
  # Limit all requests to gpt4 model from openai-main account for user:[email protected] to
  # 1000 requests per day
  - id: "openai-gpt4-dev-env"
    when: 
      subjects: ["user:[email protected]"]
      models: ["openai-main/gpt4"]
    limit_to: 1000
    unit: requests_per_day
  # Limit all requests to gpt4 model for team:backend to 20000 tokens per minute
  - id: "openai-gpt4-dev-env"
    when: 
      subjects: ["team:backend"]
      models: ["openai-main/gpt4"]
    limit_to: 20000
    unit: tokens_per_minute
  # Limit all requests to gpt4 model for serviceaccount:serviceaccount1 to 20000 tokens per minute
  - id: "openai-gpt4-dev-env"
    when: 
      subjects: ["serviceaccount:serviceaccount1"]
      models: ["openai-main/gpt4"]
    limit_to: 20000
    unit: tokens_per_minute
  # Limit all models to have a limit of 1000000 tokens per day 
  - id: "{model}-daily-limit"
 		when: {}
    limit_to: 1000000
    unit: tokens_per_day
  # Limit all users to have a limit of 1000000 tokens per day 
  - id: "{user}-daily-limit"
  	when:{}
    limit_to: 1000000
  # Limit all users to have a limit of 1000000 tokens per day for each model 
  - id: "{user}-{model}-daily-limit"
  	when: {}
    limit_to: 1000000
    unit: tokens_per_day
