Class Fireworks

Wrapper around Fireworks API for large language models

Fireworks API is compatible to the OpenAI API with some limitations described in https://readme.fireworks.ai/docs/openai-compatibility.

To use, you should have the openai package installed and the FIREWORKS_API_KEY environment variable set.

    Returns Fireworks

Properties

batchSize

batchSize: number = 20

Batch size to use when passing multiple documents to generate

frequencyPenalty

frequencyPenalty: number = 0

Penalizes repeated tokens according to frequency

maxTokens

maxTokens: number = 256

Maximum number of tokens to generate in the completion. -1 returns as many tokens as possible given the prompt and the model's maximum context size.

modelName

modelName: string = "gpt-3.5-turbo-instruct"

Model name to use

n

n: number = 1

Number of completions to generate for each prompt

presencePenalty

presencePenalty: number = 0

Penalizes repeated tokens

streaming

streaming: boolean = false

Whether to stream the results or not. Enabling disables tokenUsage reporting

temperature

temperature: number = 0.7

Sampling temperature to use

topP

topP: number = 1

Total probability mass of tokens to consider at each step

Optional azureOpenAIApiDeploymentName

azureOpenAIApiDeploymentName?: string

Azure OpenAI API deployment name to use for completions when making requests to Azure OpenAI. This is the name of the deployment you created in the Azure portal. e.g. "my-openai-deployment" this will be used in the endpoint URL: https://{InstanceName}.openai.azure.com/openai/deployments/my-openai-deployment/

Optional azureOpenAIApiInstanceName

azureOpenAIApiInstanceName?: string

Azure OpenAI API instance name to use when making requests to Azure OpenAI. this is the name of the instance you created in the Azure portal. e.g. "my-openai-instance" this will be used in the endpoint URL: https://my-openai-instance.openai.azure.com/openai/deployments/{DeploymentName}/

Optional azureOpenAIApiKey

azureOpenAIApiKey?: string

API key to use when making requests to Azure OpenAI.

Optional azureOpenAIApiVersion

azureOpenAIApiVersion?: string

API version to use when making requests to Azure OpenAI.

Optional azureOpenAIBasePath

azureOpenAIBasePath?: string

Custom endpoint for Azure OpenAI API. This is useful in case you have a deployment in another region. e.g. setting this value to "https://westeurope.api.cognitive.microsoft.com/openai/deployments" will be result in the endpoint URL: https://westeurope.api.cognitive.microsoft.com/openai/deployments/{DeploymentName}/

Optional bestOf

bestOf?: number

Generates bestOf completions server side and returns the "best"

Optional fireworksApiKey

fireworksApiKey?: string

Optional logitBias

logitBias?: Record<string, number>

Dictionary used to adjust the probability of specific tokens being generated

Optional modelKwargs

modelKwargs?: Record<string, any>

Holds any additional parameters that are valid to pass to openai.createCompletion that are not explicitly specified on this class.

Optional openAIApiKey

openAIApiKey?: string

API key to use when making requests to OpenAI. Defaults to the value of OPENAI_API_KEY environment variable.

Optional organization

organization?: string

Optional stop

stop?: string[]

List of stop words to use when generating

Optional timeout

timeout?: number

Timeout to use when making requests to OpenAI.

Optional user

user?: string

Unique string identifier representing your end-user, which can help OpenAI to monitor and detect abuse.
