            Important: when using JSON mode, it''s crucial to also instruct the model to produce JSON 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. In this case the return value might not be a valid JSON.'

          description: 'Whether to include performance metrics in the response body.


            **Non-streaming requests:** Performance metrics are always included in response headers (e.g., `fireworks-prompt-tokens`, `fireworks-server-time-to-first-token`). Setting this to `true` additionally includes the same metrics in the response body under the `perf_metrics` field.


            **Streaming requests:** Performance metrics are only included in the response body under the `perf_metrics` field in the final chunk (when `finish_reason` is set). This is because headers may not be accessible during streaming.


            The response body `perf_metrics` field contains the following metrics:


            **Basic Metrics (all deployments):**


            - `prompt-tokens`: Number of tokens in the prompt

            - `cached-prompt-tokens`: Number of cached prompt tokens

            - `server-time-to-first-token`: Time from request start to first token (in seconds)

            - `server-processing-time`: Total processing time (in seconds, only for completed requests)


            **Predicted Outputs Metrics:**


            - `speculation-prompt-tokens`: Number of speculative prompt tokens

            - `speculation-prompt-matched-tokens`: Number of matched speculative prompt tokens (for completed requests)


            **Dedicated Deployment Only Metrics:**


            - `speculation-generated-tokens`: Number of speculative generated tokens (for completed requests)

            - `speculation-acceptance`: Speculation acceptance rates by position

            - `backend-host`: Hostname of the backend server

            - `num-concurrent-requests`: Number of concurrent requests

            - `deployment`: Deployment name

            - `tokenizer-queue-duration`: Time spent in tokenizer queue

            - `tokenizer-duration`: Time spent in tokenizer

            - `prefill-queue-duration`: Time spent in prefill queue

            - `prefill-duration`: Time spent in prefill

For a good balance, a value of `1.2` is often recommended. Note that the penalty is applied to both the generated output and the prompt in decoder-only models.

            Passing `error` would trigger a request error.


            The default of `''truncate''` is selected as it allows to ask for high `max_tokens` value while respecting the context window length without having to do client-side prompt tokenization.

          description: 'Controls reasoning behavior for supported models. When enabled, the model''s reasoning appears in the `reasoning_content` field of the response, separate from the final answer in `content`.


            **Accepted values:**


            - **String** (OpenAI-compatible): `''low''`, `''medium''`, `''high''`, or `''max''` to enable reasoning with varying effort levels; `''none''` to disable reasoning.

            - **Boolean** (Fireworks extension): `true` to enable reasoning, `false` to disable it.

            - **Integer** (Fireworks extension): A positive integer to set a hard token limit on reasoning output (only effective for grammar-based reasoning models).


            **Important:** Boolean values are normalized internally: `true` becomes `''medium''`, and `false` becomes `''none''`. This normalization happens before model-specific validation, so if a model doesn''t support `''none''`, passing `false` will produce an error referencing `''none''`.


            **Model-specific behavior:**


            - **Qwen3 (e.g., Qwen3-8B)**: Grammar-based reasoning. Default reasoning on. Use `''none''` or `false` to disable. Supports integer token limits to cap reasoning output. `''low''` maps to a default token limit (~3000 tokens).

            - **MiniMax M2**: Reasoning is required (always on). Defaults to `''medium''` when omitted. Accepts only string `reasoning_effort`: `''low''`, `''medium''`, or `''high''`. `''none''` and boolean values are rejected.

            - **DeepSeek V3.1**: Binary on/off reasoning. Default reasoning off (matches chat template). Use `true`, `''low''`, `''medium''`, or `''high''` to enable; `''none''` or `false` to disable.

            - **DeepSeek V3.2**: Binary on/off reasoning. Default reasoning on. Use `''none''` or `false` to disable; effort levels and integers have no additional effect.

            - **DeepSeek V4**: Accepts `''none''`, `''low''`, `''medium''`, `''high''`, and `''max''`. Default reasoning on (`''high''`). `''max''` prepends a thorough-reasoning preamble; `''high''` enables thinking. `''low''` and `''medium''` are silently promoted to `''high''`. `''none''` or `false` disables thinking.

            - **GLM 4.5, GLM 4.5 Air, GLM 4.6, GLM 4.7**: Binary on/off reasoning. Default reasoning on. Use `''none''` or `false` to disable; effort levels and integers have no additional effect.

            - **Harmony (OpenAI GPT-OSS 120B, GPT-OSS 20B)**: Accepts only `''low''`, `''medium''`, or `''high''`. Does not support `''none''`, `false`, or integer values — using these will return an error (e.g., "Invalid reasoning effort: none"). When omitted, defaults to `''medium''`. Lower effort produces faster responses with shorter reasoning.'
