        &quot;mediaResolution&quot;: &quot;A String&quot;, # Optional. The token resolution at which input media content is sampled. This is used to control the trade-off between the quality of the response and the number of tokens used to represent the media.

        &quot;responseLogprobs&quot;: True or False, # Optional. If set to true, the log probabilities of the output tokens are returned. Log probabilities are the logarithm of the probability of a token appearing in the output. A higher log probability means the token is more likely to be generated. This can be useful for analyzing the model&#x27;s confidence in its own output and for debugging.
        &quot;responseMimeType&quot;: &quot;A String&quot;, # Optional. The IANA standard MIME type of the response. The model will generate output that conforms to this MIME type. Supported values include &#x27;text/plain&#x27; (default) and &#x27;application/json&#x27;. The model needs to be prompted to output the appropriate response type, otherwise the behavior is undefined. This is a preview feature.
        &quot;responseModalities&quot;: [ # Optional. The modalities of the response. The model will generate a response that includes all the specified modalities. For example, if this is set to `[TEXT, IMAGE]`, the response will include both text and an image.

        },
        &quot;seed&quot;: 42, # Optional. A seed for the random number generator. By setting a seed, you can make the model&#x27;s output mostly deterministic. For a given prompt and parameters (like temperature, top_p, etc.), the model will produce the same response every time. However, it&#x27;s not a guaranteed absolute deterministic behavior. This is different from parameters like `temperature`, which control the *level* of randomness. `seed` ensures that the &quot;random&quot; choices the model makes are the same on every run, making it essential for testing and ensuring reproducible results.

          &quot;A String&quot;,
        ],
        &quot;temperature&quot;: 3.14, # Optional. Controls the randomness of the output. A higher temperature results in more creative and diverse responses, while a lower temperature makes the output more predictable and focused. The valid range is (0.0, 2.0].
        &quot;thinkingConfig&quot;: { # Configuration for the model&#x27;s thinking features. &quot;Thinking&quot; is a process where the model breaks down a complex task into smaller, manageable steps. This allows the model to reason about the task, plan its approach, and execute the plan to generate a high-quality response. # Optional. Configuration for thinking features. An error will be returned if this field is set for models that don&#x27;t support thinking.
          &quot;includeThoughts&quot;: True or False, # Optional. If true, the model will include its thoughts in the response. &quot;Thoughts&quot; are the intermediate steps the model takes to arrive at the final response.

          &quot;thinkingBudget&quot;: 42, # Optional. The token budget for the model&#x27;s thinking process. The model will make a best effort to stay within this budget. This can be used to control the trade-off between response quality and latency.
        },
        &quot;topK&quot;: 3.14, # Optional. Specifies the top-k sampling threshold. The model considers only the top k most probable tokens for the next token. This can be useful for generating more coherent and less random text. For example, a `top_k` of 40 means the model will choose the next word from the 40 most likely words.
        &quot;topP&quot;: 3.14, # Optional. Specifies the nucleus sampling threshold. The model considers only the smallest set of tokens whose cumulative probability is at least `top_p`. This helps generate more diverse and less repetitive responses. For example, a `top_p` of 0.9 means the model considers tokens until the cumulative probability of the tokens to select from reaches 0.9. It&#x27;s recommended to adjust either temperature or `top_p`, but not both.

This is used to control the trade-off between the quality of the response and the number of tokens used to represent the media. A higher resolution allows the model to perceive more detail, which can lead to a more nuanced response, but it will also use more tokens. This does not affect the image dimensions sent to the model.

For a given prompt and parameters (like temperature, top_p, etc.), the model will produce the same response every time. However, it&#x27;s not a guaranteed absolute deterministic behavior. This is different from parameters like `temperature`, which control the *level* of randomness. `seed` ensures that the &quot;random&quot; choices the model makes are the same on every run, making it essential for testing and ensuring reproducible results.

        ],
        &quot;temperature&quot;: 3.14, # Optional. Controls the randomness of the output. A higher temperature results in more creative and diverse responses, while a lower temperature makes the output more predictable and focused. The valid range is (0.0, 2.0].

This allows the model to reason about the task, plan its approach, and execute the plan to generate a high-quality response. # Optional. Configuration for thinking features. An error will be returned if this field is set for models that don&#x27;t support thinking.
          &quot;includeThoughts&quot;: True or False, # Optional. If true, the model will include its thoughts in the response. &quot;Thoughts&quot; are the intermediate steps the model takes to arrive at the final response.

        &quot;topP&quot;: 3.14, # Optional. Specifies the nucleus sampling threshold. The model considers only the smallest set of tokens whose cumulative probability is at least `top_p`. This helps generate more diverse and less repetitive responses. For example, a `top_p` of 0.9 means the model considers tokens until the cumulative probability of the tokens to select from reaches 0.9. It&#x27;s recommended to adjust either temperature or `top_p`, but not both.

This is used to control the trade-off between the quality of the response and the number of tokens used to represent the media. A higher resolution allows the model to perceive more detail, which can lead to a more nuanced response, but it will also use more tokens. This does not affect the image dimensions sent to the model.

This parameter can be used to control the length of the generated text and prevent overly long responses.
                &quot;mediaResolution&quot;: &quot;A String&quot;, # Optional. The token resolution at which input media content is sampled. This is used to control the trade-off between the quality of the response and the number of tokens used to represent the media. A higher resolution allows the model to perceive more detail, which can lead to a more nuanced response, but it will also use more tokens. This does not affect the image dimensions sent to the model.

        &quot;topK&quot;: 3.14, # Optional. Specifies the top-k sampling threshold. The model considers only the top k most probable tokens for the next token. This can be useful for generating more coherent and less random text. For example, a `top_k` of 40 means the model will choose the next word from the 40 most likely words.
        &quot;topP&quot;: 3.14, # Optional. Specifies the nucleus sampling threshold. The model considers only the smallest set of tokens whose cumulative probability is at least `top_p`. This helps generate more diverse and less repetitive responses. For example, a `top_p` of 0.9 means the model considers tokens until the cumulative probability of the tokens to select from reaches 0.9. It&#x27;s recommended to adjust either temperature or `top_p`, but not both.

            &quot;seed&quot;: 42, # Optional. A seed for the random number generator. By setting a seed, you can make the model&#x27;s output mostly deterministic. For a given prompt and parameters (like temperature, top_p, etc.), the model will produce the same response every time. However, it&#x27;s not a guaranteed absolute deterministic behavior. This is different from parameters like `temperature`, which control the *level* of randomness. `seed` ensures that the &quot;random&quot; choices the model makes are the same on every run, making it essential for testing and ensuring reproducible results.
            &quot;speechConfig&quot;: { # Configuration for speech generation. # Optional. The speech generation config.

If a stop sequence is generated, the output will end at that point. This is useful for controlling the length and structure of the output. For example, you can use [&quot;\n&quot;, &quot;###&quot;] to stop generation at a new line or a specific marker.
              &quot;A String&quot;,
            ],
            &quot;temperature&quot;: 3.14, # Optional. Controls the randomness of the output. A higher temperature results in more creative and diverse responses, while a lower temperature makes the output more predictable and focused. The valid range is (0.0, 2.0].
            &quot;thinkingConfig&quot;: { # Configuration for the model&#x27;s thinking features. &quot;Thinking&quot; is a process where the model breaks down a complex task into smaller, manageable steps. This allows the model to reason about the task, plan its approach, and execute the plan to generate a high-quality response. # Optional. Configuration for thinking features. An error will be returned if this field is set for models that don&#x27;t support thinking.
              &quot;includeThoughts&quot;: True or False, # Optional. If true, the model will include its thoughts in the response. &quot;Thoughts&quot; are the intermediate steps the model takes to arrive at the final response. They can provide insights into the model&#x27;s reasoning process and help with debugging. If this is true, thoughts are returned only when available.
              &quot;thinkingBudget&quot;: 42, # Optional. The token budget for the model&#x27;s thinking process. The model will make a best effort to stay within this budget. This can be used to control the trade-off between response quality and latency.
            },
            &quot;topK&quot;: 3.14, # Optional. Specifies the top-k sampling threshold. The model considers only the top k most probable tokens for the next token. This can be useful for generating more coherent and less random text. For example, a `top_k` of 40 means the model will choose the next word from the 40 most likely words.
            &quot;topP&quot;: 3.14, # Optional. Specifies the nucleus sampling threshold. The model considers only the smallest set of tokens whose cumulative probability is at least `top_p`. This helps generate more diverse and less repetitive responses. For example, a `top_p` of 0.9 means the model considers tokens until the cumulative probability of the tokens to select from reaches 0.9. It&#x27;s recommended to adjust either temperature or `top_p`, but not both.
