Supported API reference routes for this model.
import Phaseo from '@phaseo/sdk';
const client = new Phaseo({
apiKey: process.env.PHASEO_API_KEY,
});
const response = await client.generateResponse({
"model": "spacex-ai/grok-4.5",
"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);Parameters
Aggregated across active providers for the responses route.
Routing will select a compatible provider when a parameter narrows availability, so this list stays model-facing instead of provider-facing.
| 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. |
seed | Requests deterministic sampling when the upstream provider supports seeded generation. |
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. |
reasoning | Provider-specific reasoning configuration for reasoning-capable APIs. |
include_reasoning | Requests reasoning content or reasoning summaries in responses where supported. |
