FIMCompletionParams

class FIMCompletionParams : DeepSeekParams

Parameters for configuring Fill-in-the-Middle (FIM) completion requests to DeepSeek models.

FIM allows the model to complete text where you provide both a prefix and a suffix, making it useful for code completion, text infilling, and template-based generation.

Example:

val params = fimCompletionParams {
    temperature = 0.7
    maxTokens = 200
    suffix = "}"  // The code should end with a closing bracket
}

val completion = client.fim(params, "function calculateArea(radius) {")
println(completion.choices.first().text)

Types

Builder

class Builder

Builder for creating FIMCompletionParams with standard (non-streaming) configuration.

StreamBuilder

class StreamBuilder

Builder for creating FIMCompletionParams specifically configured for streaming responses.

Properties

echo

val echo: Boolean?

Whether to include the prompt in the returned completion

frequencyPenalty

val frequencyPenalty: Double?

Reduces repetition by penalizing tokens based on their frequency in the text. Expected range: -2.0..2.0.

logprobs

val logprobs: Int?

Maximum number of log probabilities to return (up to 20)

maxTokens

val maxTokens: Int?

Maximum number of tokens to generate in the response. Expected range: 1..8192.

presencePenalty

val presencePenalty: Double?

Reduces repetition by penalizing tokens that have appeared in the text. Expected range: -2.0..2.0.

stop

val stop: StopReason?

Custom stop sequences that cause the model to stop generating further tokens.

stream

val stream: Boolean?

Whether to stream the response back piece by piece

streamOptions

val streamOptions: StreamOptions?

Configuration options for streaming responses

suffix

val suffix: String?

Text that the model should complete towards (the ending part in FIM)

temperature

val temperature: Double?

Controls randomness in output generation (higher = more random). Expected range: 0.0..2.0.

topP

val topP: Double?

Controls diversity via nucleus sampling (consider only tokens with top_p probability mass). Expected range: 0.0..1.0.
