To request successfully, it is mandatory to enter a **Personal API Key** (e.g. flp_XXX) value in the **Bearer Token** field.
Refer to the [authentication section](/openapi/introduction#authentication) on our introduction page to learn how to acquire this variable and [visit here](https://friendli.ai/suite/~/setting/keys) to generate your API Key.
When streaming mode is used (i.e., `stream` option is set to `true`), the response is in MIME type `text/event-stream`. Otherwise, the content type is `application/json`.
You can view the schema of the streamed sequence of chunk objects in streaming mode [here](/openapi/model-apis/tool-assisted-chat-completions-chunk-object).
You can explore examples on the [Friendli Model APIs](https://friendli.ai/get-started/model-apis) playground and adjust settings with just a few clicks.
Tool assisted chat completions does not fully support parallel tool calls now.
This API is currently in **Beta**.
While we strive to provide a stable and reliable experience, this feature is still under active development.
As a result, you may encounter unexpected behavior or limitations.
We encourage you to provide feedback to help us improve the feature before its official release.

logit_bias:
anyOf:
- additionalProperties: true
type: object
- type: 'null'
title: Logit Bias
description: Accepts a JSON object that maps tokens to an associated bias value. Mathematically, the bias is added to the logits generated by the model prior to sampling. The exact effect will vary per model.
logprobs:
anyOf:
- type: boolean
- type: 'null'
title: Logprobs
description: Whether to return log probabilities of the output tokens or not.
max_tokens:
anyOf:
- type: integer
- type: 'null'
title: Max Tokens
description: The maximum number of tokens to generate. For decoder-only models like GPT, the length of your input tokens plus `max_tokens` should not exceed the model's maximum length (e.g., 2048 for OpenAI GPT-3). For encoder-decoder models like T5 or BlenderBot, `max_tokens` should not exceed the model's maximum output length. This is similar to Hugging Face's [`max_new_tokens`](https://huggingface.co/docs/transformers/v4.26.0/en/main_classes/text_generation#transformers.GenerationConfig.max_new_tokens) argument.
min_p:
anyOf:
- type: number
- type: 'null'
title: Min P
description: A scaling factor used to determine the minimum token probability threshold. This threshold is calculated as `min_p` multiplied by the probability of the most likely token. Tokens with probabilities below this scaled threshold are excluded from sampling. Values range from 0.0 (inclusive) to 1.0 (inclusive). Higher values result in stricter filtering, while lower values allow for greater diversity. The default value of 0.0 disables filtering, allowing all tokens to be considered for sampling.
n:
anyOf:
- type: integer
- type: 'null'
title: N
description: The number of independently generated results for the prompt. Defaults to 1. This is similar to Hugging Face's [`num_return_sequences`](https://huggingface.co/docs/transformers/v4.26.0/en/main_classes/text_generation#transformers.GenerationConfig.num_return_sequences) argument.
parallel_tool_calls:
anyOf:
- type: boolean
- type: 'null'
title: Parallel Tool Calls
description: Whether to enable parallel function calling.
presence_penalty:
anyOf:
- type: number
- type: 'null'
title: Presence Penalty
description: Number between -2.0 and 2.0. Positive values penalizes tokens that have been sampled at least once in the existing text.
repetition_penalty:
anyOf:
- type: number
- type: 'null'
title: Repetition Penalty
description: Penalizes tokens that have already appeared in the generated result (plus the input tokens for decoder-only models). Should be positive value (1.0 means no penalty). See [keskar et al., 2019](https://arxiv.org/abs/1909.05858) for more details. This is similar to Hugging Face's [`repetition_penalty`](https://huggingface.co/docs/transformers/v4.26.0/en/main_classes/text_generation#transformers.generationconfig.repetition_penalty) argument.
reasoning_effort:
anyOf:
- type: string
enum:
- minimal
- low
- medium
- high
- xhigh
- max
- ultracode
- type: 'null'
title: Reasoning Effort
description: Sets how much reasoning the model does before answering. Higher values give more thorough responses but take longer. This affects reasoning models only, and the available options depend on the model.
reasoning_budget:
anyOf:
- type: integer
- type: 'null'
title: Reasoning Budget
description: Specifies a positive integer that defines a limit on the number of tokens used for internal reasoning tokens. This parameter is only effective for reasoning models.
seed:
anyOf:
- items:
type: integer
type: array
- type: integer
- type: 'null'
title: Seed
description: Seed to control random procedure. If nothing is given, random seed is used for sampling, and return the seed along with the generated result. When using the `n` argument, you can pass a list of seed values to control all of the independent generations.
stop:
anyOf:
- items:
type: string
type: array
- type: 'null'
title: Stop
description: When one of the stop phrases appears in the generation result, the API will stop generation. The stop phrases are excluded from the result. Defaults to empty list.

- type: 'null'
title: Stream
description: Whether to stream the generation result. When set to `true`, each token is sent as [server-sent events](https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events/Using_server-sent_events#event_stream_format) once generated.
default: false

description: 'Determines the tool calling behavior of the model.
When set to `none`, the model will bypass tool execution and generate a response directly.
In `auto` mode (the default), the model dynamically decides whether to call a tool or respond with a message.
Alternatively, setting `required` ensures that the model invokes at least one tool before responding to the user.
You can also specify a particular tool by `{"type": "function", "function": {"name": "my_function"}}`.

title: Xtc Threshold
description: A probability threshold used to identify “top choice” tokens for exclusion in XTC (Exclude Top Choices) sampling. Tokens with probabilities at or above this threshold are considered viable candidates, and all but the least likely viable token are excluded from sampling. This option reduces the dominance of highly probable tokens while preserving some diversity by keeping the least confident “top choice.” Values range from 0.0 (inclusive) to 1.0 (inclusive). Higher values make the filtering more selective by requiring higher probabilities to trigger exclusion, while lower values apply filtering more broadly. The default value of 0.0 disables XTC filtering entirely.
xtc_probability:
anyOf:

title: Xtc Probability
description: The probability that XTC (Exclude Top Choices) filtering will be applied for each sampling decision. When XTC is triggered, high-probability tokens above the `xtc_threshold` are excluded except for the least likely viable token. This stochastic activation allows for a balance between standard sampling and creativity-boosting exclusion filtering. Values range from 0.0 (inclusive) to 1.0 (inclusive), where 0.0 means XTC is never applied, 1.0 means XTC is always applied when viable tokens exist, and intermediate values provide probabilistic activation. The default value of 0.0 disables XTC filtering.
