Properties

OptionalapiKey

apiKey?: string

API key for Perplexity. Defaults to the value of PERPLEXITY_API_KEY environment variable.

Optionalcache

cache?: boolean | BaseCache<Generation[]>

OptionalcallbackManager

callbackManager?: CallbackManager

Deprecated

Use callbacks instead

Optionalcallbacks

callbacks?: Callbacks

OptionaldisableSearch

disableSearch?: boolean

When set to true, disables web search completely and the model will only use its training data to respond. This is useful when you want deterministic responses without external information.

OptionaldisableStreaming

disableStreaming?: boolean

Whether to disable streaming.

If streaming is bypassed, then stream() will defer to invoke().

  • If true, will always bypass streaming case.
  • If false (default), will always use streaming case if available.

OptionalenableSearchClassifier

enableSearchClassifier?: boolean

Enables a classifier that decides if web search is needed based on your query.

OptionalfrequencyPenalty

frequencyPenalty?: number

Frequency penalty greater than 0

OptionallastUpdatedAfterFilter

lastUpdatedAfterFilter?: string

Filters search results to only include content last updated after this date.

OptionallastUpdatedBeforeFilter

lastUpdatedBeforeFilter?: string

Filters search results to only include content last updated before this date.

OptionalmaxConcurrency

maxConcurrency?: number

The maximum number of concurrent calls that can be made. Defaults to Infinity, which means no limit.

OptionalmaxRetries

maxRetries?: number

The maximum number of retries that can be made for a single call, with an exponential backoff between each attempt. Defaults to 6.

OptionalmaxTokens

maxTokens?: number

Maximum number of tokens to generate

Optionalmetadata

metadata?: Record<string, unknown>

model

model: string

Model name to use

OptionalonFailedAttempt

onFailedAttempt?: FailedAttemptHandler

Custom handler to handle failed attempts. Takes the originally thrown error object as input, and should itself throw an error if the input error is not retryable.

OptionalpresencePenalty

presencePenalty?: number

Presence penalty between -2 and 2

OptionalreasoningEffort

reasoningEffort?: "low" | "medium" | "high"

Controls how much computational effort the AI dedicates to each query for deep research models. Only applicable for sonar-deep-research.

OptionalreturnImages

returnImages?: boolean

Whether to return images

OptionalreturnRelatedQuestions

returnRelatedQuestions?: boolean

Determines whether or not a request to an online model should return related questions.

OptionalsearchAfterDateFilter
