"""
Creates a model response for the given chat conversation.
Args:
messages: A list of messages comprising the conversation so far.
[Example Python code](https://cookbook.openai.com/examples/how_to_format_inputs_to_chatgpt_models).
model: ID of the model to use. See the
[model endpoint compatibility](https://platform.openai.com/docs/models/model-endpoint-compatibility)
table for details on which models work with the Chat API.
frequency_penalty: Number between -2.0 and 2.0. Positive values penalize new tokens based on their
existing frequency in the text so far, decreasing the model's likelihood to
repeat the same line verbatim.
[See more information about frequency and presence penalties.](https://platform.openai.com/docs/guides/text-generation/parameter-details)
function_call: Deprecated in favor of `tool_choice`.
Controls which (if any) function is called by the model. `none` means the model
will not call a function and instead generates a message. `auto` means the model
can pick between generating a message or calling a function. Specifying a
particular function via `{"name": "my_function"}` forces the model to call that
function.
`none` is the default when no functions are present. `auto` is the default if
functions are present.
functions: Deprecated in favor of `tools`.
A list of functions the model may generate JSON inputs for.
logit_bias: Modify the likelihood of specified tokens appearing in the completion.
Accepts a JSON object that maps tokens (specified by their token ID in the
tokenizer) to an associated bias value from -100 to 100. Mathematically, the
bias is added to the logits generated by the model prior to sampling. The exact
effect will vary per model, but values between -1 and 1 should decrease or
increase likelihood of selection; values like -100 or 100 should result in a ban
or exclusive selection of the relevant token.
logprobs: Whether to return log probabilities of the output tokens or not. If true,
returns the log probabilities of each output token returned in the `content` of
`message`.
max_tokens: The maximum number of [tokens](/tokenizer) that can be generated in the chat
completion.
The total length of input tokens and generated tokens is limited by the model's
context length.
[Example Python code](https://cookbook.openai.com/examples/how_to_count_tokens_with_tiktoken)
for counting tokens.
n: How many chat completion choices to generate for each input message. Note that
you will be charged based on the number of generated tokens across all of the
choices. Keep `n` as `1` to minimize costs.
parallel_tool_calls: Whether to enable
[parallel function calling](https://platform.openai.com/docs/guides/function-calling/parallel-function-calling)
during tool use.
presence_penalty: Number between -2.0 and 2.0. Positive values penalize new tokens based on
whether they appear in the text so far, increasing the model's likelihood to
talk about new topics.
[See more information about frequency and presence penalties.](https://platform.openai.com/docs/guides/text-generation/parameter-details)
response_format: An object specifying the format that the model must output. Compatible with
[GPT-4o](https://platform.openai.com/docs/models/gpt-4o),
[GPT-4o mini](https://platform.openai.com/docs/models/gpt-4o-mini),
[GPT-4 Turbo](https://platform.openai.com/docs/models/gpt-4-and-gpt-4-turbo) and
all GPT-3.5 Turbo models newer than `gpt-3.5-turbo-1106`.
Setting to `{ "type": "json_schema", "json_schema": {...} }` enables Structured
Outputs which guarantees the model will match your supplied JSON schema. Learn
more in the
[Structured Outputs guide](https://platform.openai.com/docs/guides/structured-outputs).
Setting to `{ "type": "json_object" }` enables JSON mode, which guarantees the
message the model generates is valid JSON.
**Important:** when using JSON mode, you **must** also instruct the model to
produce JSON yourself via a system or user message. Without this, the model may
generate an unending stream of whitespace until the generation reaches the token
limit, resulting in a long-running and seemingly "stuck" request. Also note that
the message content may be partially cut off if `finish_reason="length"`, which
indicates the generation exceeded `max_tokens` or the conversation exceeded the
max context length.
seed: This feature is in Beta. If specified, our system will make a best effort to
sample deterministically, such that repeated requests with the same `seed` and
parameters should return the same result. Determinism is not guaranteed, and you
should refer to the `system_fingerprint` response parameter to monitor changes
in the backend.
service_tier: Specifies the latency tier to use for processing the request. This parameter is
relevant for customers subscribed to the scale tier service:
- If set to 'auto', the system will utilize scale tier credits until they are
exhausted.
- If set to 'default', the request will be processed using the default service
tier with a lower uptime SLA and no latency guarentee.
- When not set, the default behavior is 'auto'.
When this parameter is set, the response body will include the `service_tier`
utilized.
stop: Up to 4 sequences where the API will stop generating further tokens.
stream: If set, partial message deltas will be sent, like in ChatGPT. Tokens will be
sent as data-only
[server-sent events](https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events/Using_server-sent_events#Event_stream_format)
as they become available, with the stream terminated by a `data: [DONE]`
message.
[Example Python code](https://cookbook.openai.com/examples/how_to_stream_completions).
stream_options: Options for streaming response. Only set this when you set `stream: true`.
temperature: What sampling temperature to use, between 0 and 2. Higher values like 0.8 will
make the output more random, while lower values like 0.2 will make it more
focused and deterministic.
We generally recommend altering this or `top_p` but not both.
tool_choice: Controls which (if any) tool is called by the model. `none` means the model will
not call any tool and instead generates a message. `auto` means the model can
pick between generating a message or calling one or more tools. `required` means
the model must call one or more tools. Specifying a particular tool via
`{"type": "function", "function": {"name": "my_function"}}` forces the model to
call that tool.
`none` is the default when no tools are present. `auto` is the default if tools
are present.
tools: A list of tools the model may call. Currently, only functions are supported as a
tool. Use this to provide a list of functions the model may generate JSON inputs
for. A max of 128 functions are supported.
top_logprobs: An integer between 0 and 20 specifying the number of most likely tokens to
return at each token position, each with an associated log probability.
`logprobs` must be set to `true` if this parameter is used.
top_p: An alternative to sampling with temperature, called nucleus sampling, where the
model considers the results of the tokens with top_p probability mass. So 0.1
means only the tokens comprising the top 10% probability mass are considered.
We generally recommend altering this or `temperature` but not both.
user: A unique identifier representing your end-user, which can help OpenAI to monitor
and detect abuse.

[Example Python code](https://cookbook.openai.com/examples/how_to_stream_completions).
frequency_penalty: Number between -2.0 and 2.0. Positive values penalize new tokens based on their

repeat the same line verbatim.
[See more information about frequency and presence penalties.](https://platform.openai.com/docs/guides/text-generation/parameter-details)
function_call: Deprecated in favor of `tool_choice`.
Controls which (if any) function is called by the model. `none` means the model
will not call a function and instead generates a message. `auto` means the model

functions: Deprecated in favor of `tools`.
A list of functions the model may generate JSON inputs for.
logit_bias: Modify the likelihood of specified tokens appearing in the completion.
Accepts a JSON object that maps tokens (specified by their token ID in the
tokenizer) to an associated bias value from -100 to 100. Mathematically, the
bias is added to the logits generated by the model prior to sampling. The exact
effect will vary per model, but values between -1 and 1 should decrease or
increase likelihood of selection; values like -100 or 100 should result in a ban
or exclusive selection of the relevant token.
logprobs: Whether to return log probabilities of the output tokens or not. If true,
returns the log probabilities of each output token returned in the `content` of
`message`.
max_tokens: The maximum number of [tokens](/tokenizer) that can be generated in the chat
completion.
The total length of input tokens and generated tokens is limited by the model's
context length.
[Example Python code](https://cookbook.openai.com/examples/how_to_count_tokens_with_tiktoken)
for counting tokens.
n: How many chat completion choices to generate for each input message. Note that
you will be charged based on the number of generated tokens across all of the
choices. Keep `n` as `1` to minimize costs.
parallel_tool_calls: Whether to enable
[parallel function calling](https://platform.openai.com/docs/guides/function-calling/parallel-function-calling)
during tool use.
presence_penalty: Number between -2.0 and 2.0. Positive values penalize new tokens based on
whether they appear in the text so far, increasing the model's likelihood to
talk about new topics.
[See more information about frequency and presence penalties.](https://platform.openai.com/docs/guides/text-generation/parameter-details)
response_format: An object specifying the format that the model must output. Compatible with
[GPT-4o](https://platform.openai.com/docs/models/gpt-4o),
[GPT-4o mini](https://platform.openai.com/docs/models/gpt-4o-mini),
[GPT-4 Turbo](https://platform.openai.com/docs/models/gpt-4-and-gpt-4-turbo) and
all GPT-3.5 Turbo models newer than `gpt-3.5-turbo-1106`.
Setting to `{ "type": "json_schema", "json_schema": {...} }` enables Structured
Outputs which guarantees the model will match your supplied JSON schema. Learn
more in the
[Structured Outputs guide](https://platform.openai.com/docs/guides/structured-outputs).
Setting to `{ "type": "json_object" }` enables JSON mode, which guarantees the
message the model generates is valid JSON.
**Important:** when using JSON mode, you **must** also instruct the model to
produce JSON yourself via a system or user message. Without this, the model may
generate an unending stream of whitespace until the generation reaches the token
limit, resulting in a long-running and seemingly "stuck" request. Also note that
the message content may be partially cut off if `finish_reason="length"`, which
indicates the generation exceeded `max_tokens` or the conversation exceeded the
max context length.
seed: This feature is in Beta. If specified, our system will make a best effort to
sample deterministically, such that repeated requests with the same `seed` and
parameters should return the same result. Determinism is not guaranteed, and you
should refer to the `system_fingerprint` response parameter to monitor changes
in the backend.

[Example Python code](https://cookbook.openai.com/examples/how_to_count_tokens_with_tiktoken)
for counting tokens.
n: How many chat completion choices to generate for each input message. Note that
you will be charged based on the number of generated tokens across all of the
choices. Keep `n` as `1` to minimize costs.
parallel_tool_calls: Whether to enable
[parallel function calling](https://platform.openai.com/docs/guides/function-calling/parallel-function-calling)
during tool use.
presence_penalty: Number between -2.0 and 2.0. Positive values penalize new tokens based on
whether they appear in the text so far, increasing the model's likelihood to
talk about new topics.
[See more information about frequency and presence penalties.](https://platform.openai.com/docs/guides/text-generation/parameter-details)
response_format: An object specifying the format that the model must output. Compatible with
[GPT-4o](https://platform.openai.com/docs/models/gpt-4o),
[GPT-4o mini](https://platform.openai.com/docs/models/gpt-4o-mini),
[GPT-4 Turbo](https://platform.openai.com/docs/models/gpt-4-and-gpt-4-turbo) and
all GPT-3.5 Turbo models newer than `gpt-3.5-turbo-1106`.
Setting to `{ "type": "json_schema", "json_schema": {...} }` enables Structured
Outputs which guarantees the model will match your supplied JSON schema. Learn
more in the
[Structured Outputs guide](https://platform.openai.com/docs/guides/structured-outputs).
Setting to `{ "type": "json_object" }` enables JSON mode, which guarantees the
message the model generates is valid JSON.
**Important:** when using JSON mode, you **must** also instruct the model to
produce JSON yourself via a system or user message. Without this, the model may
generate an unending stream of whitespace until the generation reaches the token
limit, resulting in a long-running and seemingly "stuck" request. Also note that
the message content may be partially cut off if `finish_reason="length"`, which
indicates the generation exceeded `max_tokens` or the conversation exceeded the
max context length.
seed: This feature is in Beta. If specified, our system will make a best effort to
sample deterministically, such that repeated requests with the same `seed` and
parameters should return the same result. Determinism is not guaranteed, and you
should refer to the `system_fingerprint` response parameter to monitor changes
in the backend.
service_tier: Specifies the latency tier to use for processing the request. This parameter is
relevant for customers subscribed to the scale tier service:
- If set to 'auto', the system will utilize scale tier credits until they are
exhausted.
- If set to 'default', the request will be processed using the default service
tier with a lower uptime SLA and no latency guarentee.
- When not set, the default behavior is 'auto'.
When this parameter is set, the response body will include the `service_tier`
utilized.
stop: Up to 4 sequences where the API will stop generating further tokens.
stream: If set, partial message deltas will be sent, like in ChatGPT. Tokens will be
sent as data-only
[server-sent events](https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events/Using_server-sent_events#Event_stream_format)
as they become available, with the stream terminated by a `data: [DONE]`
message.
[Example Python code](https://cookbook.openai.com/examples/how_to_stream_completions).
stream_options: Options for streaming response. Only set this when you set `stream: true`.
temperature: What sampling temperature to use, between 0 and 2. Higher values like 0.8 will
make the output more random, while lower values like 0.2 will make it more
focused and deterministic.
We generally recommend altering this or `top_p` but not both.
tool_choice: Controls which (if any) tool is called by the model. `none` means the model will
not call any tool and instead generates a message. `auto` means the model can
pick between generating a message or calling one or more tools. `required` means
the model must call one or more tools. Specifying a particular tool via
`{"type": "function", "function": {"name": "my_function"}}` forces the model to
call that tool.
`none` is the default when no tools are present. `auto` is the default if tools
are present.
tools: A list of tools the model may call. Currently, only functions are supported as a
tool. Use this to provide a list of functions the model may generate JSON inputs
for. A max of 128 functions are supported.
top_logprobs: An integer between 0 and 20 specifying the number of most likely tokens to
return at each token position, each with an associated log probability.
`logprobs` must be set to `true` if this parameter is used.
top_p: An alternative to sampling with temperature, called nucleus sampling, where the
model considers the results of the tokens with top_p probability mass. So 0.1
means only the tokens comprising the top 10% probability mass are considered.
We generally recommend altering this or `temperature` but not both.
user: A unique identifier representing your end-user, which can help OpenAI to monitor
and detect abuse.

extra_headers: Send extra headers
extra_query: Add additional query parameters to the request
extra_body: Add additional JSON properties to the request
timeout: Override the client-level default timeout for this request, in seconds

Creates a model response for the given chat conversation.
Args:
messages: A list of messages comprising the conversation so far.
[Example Python code](https://cookbook.openai.com/examples/how_to_format_inputs_to_chatgpt_models).
model: ID of the model to use. See the
[model endpoint compatibility](https://platform.openai.com/docs/models/model-endpoint-compatibility)
table for details on which models work with the Chat API.
stream: If set, partial message deltas will be sent, like in ChatGPT. Tokens will be
sent as data-only

as they become available, with the stream terminated by a `data: [DONE]`
message.
[Example Python code](https://cookbook.openai.com/examples/how_to_stream_completions).
frequency_penalty: Number between -2.0 and 2.0. Positive values penalize new tokens based on their
existing frequency in the text so far, decreasing the model's likelihood to
repeat the same line verbatim.
[See more information about frequency and presence penalties.](https://platform.openai.com/docs/guides/text-generation/parameter-details)
function_call: Deprecated in favor of `tool_choice`.
Controls which (if any) function is called by the model. `none` means the model
will not call a function and instead generates a message. `auto` means the model
can pick between generating a message or calling a function. Specifying a
particular function via `{"name": "my_function"}` forces the model to call that
function.
`none` is the default when no functions are present. `auto` is the default if
functions are present.
functions: Deprecated in favor of `tools`.
A list of functions the model may generate JSON inputs for.
logit_bias: Modify the likelihood of specified tokens appearing in the completion.
Accepts a JSON object that maps tokens (specified by their token ID in the
tokenizer) to an associated bias value from -100 to 100. Mathematically, the
bias is added to the logits generated by the model prior to sampling. The exact
effect will vary per model, but values between -1 and 1 should decrease or
increase likelihood of selection; values like -100 or 100 should result in a ban
or exclusive selection of the relevant token.
logprobs: Whether to return log probabilities of the output tokens or not. If true,
returns the log probabilities of each output token returned in the `content` of
`message`.
max_tokens: The maximum number of [tokens](/tokenizer) that can be generated in the chat
completion.
