import AIStats from '@ai-stats/sdk'; const client = new AIStats({ apiKey: process.env.AI_STATS_API_KEY, }); const response = await client.generateResponse({ "model": "openai/gpt-5.4-pro", "input": "Give me one fun fact about cURL." }); const outputText = response.output ?.flatMap((item) => item.content ?? []) .find((item) => item.type === "output_text") ?.text; console.log(outputText ?? response);

Parameter	Description
`temperature`	Controls how random token selection can be.
`top_p`	Applies nucleus sampling by limiting candidates to a probability mass threshold.
`max_tokens`	Caps output length on endpoints and providers that use the max_tokens field name.
`frequency_penalty`	Discourages repeated tokens in proportion to how often they already appeared.
`presence_penalty`	Encourages the model to explore new wording or topics after they first appear.
`seed`	Requests deterministic sampling when the upstream provider supports seeded generation.
`stop`	Defines one or more sequences that terminate generation early.
`logprobs`	Requests token-level probability data in the response.
`tool_choice`	Controls which tool, if any, the model should call.
`tools`	Defines callable tools or functions the model can invoke.
`response_format`	Requests plain text, JSON, or schema-constrained output formats.
`structured_outputs`	Capability signal for reliable schema-constrained output workflows.
`logit_bias`	Adjusts token selection bias directly when a provider exposes logit control.
`top_logprobs`	Limits how many alternative token probabilities are returned per position.
