API Responses rozszerza Chat Completions o stanowe konwersacje, wbudowane narzędzia, multimodalne wejścia plikowe oraz kontrolę rozumowania. Jest to zalecany endpoint dla modeli rozumujących OpenAI z serii o, serii GPT-5 oraz modeli Codex.

Różni dostawcy modeli obsługują różne parametry żądania i zwracają różne pola odpowiedzi. Nie wszystkie parametry wymienione w playgroundzie powyżej działają z każdym modelem w CometAPI.

Używaj stanowych konwersacji

Łącz odpowiedzi za pomocą previous_response_id zamiast samodzielnie zarządzać historią wiadomości:

from openai import OpenAI

client = OpenAI(
    base_url="https://api.cometapi.com/v1",
    api_key="<COMETAPI_KEY>",
)

# First turn
response = client.responses.create(
    model="gpt-5.4",
    input="What is quantum computing?",
)

# Second turn — previous context is included automatically
follow_up = client.responses.create(
    model="gpt-5.4",
    input="Can you explain that more simply?",
    previous_response_id=response.id,
)

print(follow_up.output_text)

Używaj wbudowanych narzędzi

API Responses zawiera narzędzia dostarczane przez platformę, które nie wymagają konfiguracji:

Narzędzie	Cel
`web_search_preview`	Przeszukuje internet w poszukiwaniu informacji w czasie rzeczywistym
`file_search`	Przeszukuje przesłane pliki
`code_interpreter`	Wykonuje kod Python w sandboxie

Aby włączyć wbudowane narzędzie, dodaj je do tablicy tools:

response = client.responses.create(
    model="gpt-5.4",
    input="Find the current price of Bitcoin",
    tools=[{"type": "web_search_preview"}],
)

print(response.output_text)

Wywołuj własne funkcje

Zdefiniuj funkcje, które model może wywoływać przy użyciu uporządkowanych argumentów:

response = client.responses.create(
    model="gpt-5.4",
    input="What's the weather in Tokyo?",
    tools=[{
        "type": "function",
        "name": "get_weather",
        "description": "Get current weather for a location",
        "parameters": {
            "type": "object",
            "properties": {
                "location": {"type": "string"}
            },
            "required": ["location"]
        }
    }],
)

Gdy model wywoła funkcję, tablica output w odpowiedzi zawiera element function_call z nazwą funkcji i sparsowanymi argumentami. Wykonaj funkcję i odeślij wynik w kolejnym żądaniu.

Żądaj uporządkowanego wyniku

Aby wymusić wynik JSON zgodny z określonym schematem, użyj parametru text.format:

response = client.responses.create(
    model="gpt-5.4",
    input="List 3 programming languages with their main use cases",
    text={
        "format": {
            "type": "json_schema",
            "name": "languages",
            "strict": True,
            "schema": {
                "type": "object",
                "properties": {
                    "languages": {
                        "type": "array",
                        "items": {
                            "type": "object",
                            "properties": {
                                "name": {"type": "string"},
                                "use_case": {"type": "string"}
                            },
                            "required": ["name", "use_case"],
                            "additionalProperties": False
                        }
                    }
                },
                "required": ["languages"],
                "additionalProperties": False
            }
        }
    },
)

Konfiguracja reasoning

Dla modeli z serii o i GPT-5 kontroluj głębokość reasoning za pomocą reasoning.effort:

response = client.responses.create(
    model="o3",
    input="Solve this step by step: if f(x) = x^3 - 6x^2 + 11x - 6, find all roots.",
    reasoning={"effort": "high"},  # "low", "medium", or "high"
)

print(response.output_text)

Wyższy poziom reasoning daje bardziej szczegółowe odpowiedzi, ale zużywa więcej tokenów. Użyj "low" dla prostych zapytań i "high" dla złożonych problemów wieloetapowych.

Streamowanie odpowiedzi

Aby otrzymywać przyrostowe dane wyjściowe, ustaw stream na true. API wysyła zdarzenia server-sent events (SSE) w tej kolejności:

response.created — Obiekt odpowiedzi zainicjalizowany
response.in_progress — Rozpoczęto generowanie
response.output_item.added — Nowy element wyjściowy (wiadomość lub wywołanie narzędzia)
response.content_part.added — Rozpoczęto część treści
response.output_text.delta — Fragment tekstu (zawiera pole delta)
response.output_text.done — Generowanie tekstu zakończone dla tej części treści
response.content_part.done — Zakończono część treści
response.output_item.done — Zakończono element wyjściowy
response.completed — Pełna odpowiedź z danymi usage

Streamuj odpowiedź za pomocą Python SDK:

stream = client.responses.create(
    model="gpt-5.4",
    input="Write a haiku about coding",
    stream=True,
)

for event in stream:
    if event.type == "response.output_text.delta":
        print(event.delta, end="")

Autoryzacje

Authorization

string

header

wymagane

Bearer token authentication. Use your CometAPI key.

Treść

application/json

model

string

wymagane

Model ID to use for this request. See the Models page for current options.

Przykład:

"gpt-5.4"

input

wymagane

Text, image, or file inputs to the model, used to generate a response. Can be a simple string for text-only input, or an array of input items for multimodal content (images, files) and multi-turn conversations.

instructions

string

A system (or developer) message inserted into the model's context. When used with previous_response_id, instructions from the previous response are not carried over — this makes it easy to swap system messages between turns.

background

boolean

domyślnie:false

Whether to run the model response in the background. Background responses do not return output directly — you retrieve the result later via the response ID.

context_management

object[]

Context management configuration for this request. Controls how the model manages context when the conversation exceeds the context window.

Show child attributes

conversation

The conversation this response belongs to. Items from the conversation are prepended to input for context. Input and output items are automatically added to the conversation after the response completes. Cannot be used with previous_response_id.

include

enum<string>[]

Additional output data to include in the response. Use this to request extra information that is not included by default.

Dostępne opcje:

web_search_call.action.sources,

code_interpreter_call.outputs,

computer_call_output.output.image_url,

file_search_call.results,

message.input_image.image_url,

message.output_text.logprobs,

reasoning.encrypted_content

max_output_tokens

integer

An upper bound for the number of tokens that can be generated for a response, including visible output tokens and reasoning tokens.

max_tool_calls

integer

The maximum number of total calls to built-in tools that can be processed in a response. This limit applies across all built-in tool calls, not per individual tool. Any further tool call attempts by the model will be ignored.

metadata

object

Set of up to 16 key-value pairs that can be attached to the response. Useful for storing additional information in a structured format. Keys have a maximum length of 64 characters; values have a maximum length of 512 characters.

Show child attributes

parallel_tool_calls

boolean

domyślnie:true

Whether to allow the model to run tool calls in parallel.

previous_response_id

string

The unique ID of a previous response. Use this to create multi-turn conversations without manually managing conversation state. Cannot be used with conversation.

prompt

object

Reference to a prompt template and its variables.

Show child attributes

prompt_cache_key

string

A key used to cache responses for similar requests, helping optimize cache hit rates. Replaces the deprecated user field for caching purposes.

prompt_cache_retention

enum<string>

The retention policy for the prompt cache. Set to 24h to keep cached prefixes active for up to 24 hours.

Dostępne opcje:

in-memory,

24h

reasoning

object

Configuration options for reasoning models (o-series and gpt-5). Controls the depth of reasoning before generating a response.

Show child attributes

safety_identifier

string

A stable identifier for your end-users, used to help detect policy violations. Should be a hashed username or email — do not send identifying information directly.

Maximum string length: 64

service_tier

enum<string>

Specifies the processing tier for the request. When set, the response will include the actual service_tier used.

auto: Uses the tier configured in project settings (default behavior).
default: Standard pricing and performance.
flex: Flexible processing with potential cost savings.
priority: Priority processing with faster response times.

Dostępne opcje:

auto,

default,

flex,

priority

store

boolean

domyślnie:true

Whether to store the generated response for later retrieval via API.

stream

boolean

domyślnie:false

If set to true, the response data will be streamed to the client as it is generated using server-sent events (SSE). Events include response.created, response.output_text.delta, response.completed, and more.

stream_options

object

Options for streaming responses. Only set this when stream is true.

Show child attributes

temperature

number

domyślnie:1

Sampling temperature between 0 and 2. Higher values (e.g., 0.8) increase randomness; lower values (e.g., 0.2) make output more focused and deterministic. We recommend adjusting either this or top_p, but not both.

Wymagany zakres: 0 <= x <= 2

text

object

Configuration for text output. Use this to request structured JSON output via JSON mode or JSON Schema.

Show child attributes

tool_choice

domyślnie:auto

Controls how the model selects which tool(s) to call.

auto (default): The model decides whether and which tools to call.
none: The model will not call any tools.
required: The model must call at least one tool.
An object specifying a particular tool to use.

tools

object[]

An array of tools the model may call while generating a response. CometAPI supports three categories:

Built-in tools: Platform-provided tools like web_search_preview and file_search.
Function calls: Custom functions you define, enabling the model to call your own code with structured arguments.
MCP tools: Integrations with third-party systems via MCP servers.

top_logprobs

integer

Number of most likely tokens to return at each position (0–20), each with an associated log probability. Must include message.output_text.logprobs in the include parameter to receive logprobs.

Wymagany zakres: 0 <= x <= 20

top_p

number

domyślnie:1

Nucleus sampling parameter. The model considers tokens with top_p cumulative probability mass. For example, 0.1 means only the top 10% probability tokens are considered. We recommend adjusting either this or temperature, but not both.

Wymagany zakres: 0 <= x <= 1

truncation

enum<string>

domyślnie:disabled

The truncation strategy for handling inputs that exceed the model's context window.

auto: The model truncates the input by dropping items from the beginning of the conversation to fit.
disabled (default): The request fails with a 400 error if the input exceeds the context window.

Dostępne opcje:

auto,

disabled

user

string

przestarzałe

Deprecated. Use safety_identifier and prompt_cache_key instead. A stable identifier for your end-user.
