Generate Text (AI SDK) - Phaseo Docs

Use generateText with phaseo(modelId) for one-shot completions.

import { phaseo } from "@phaseo/ai-sdk-provider";
import { generateText } from "ai";

const result = await generateText({
  model: phaseo("openai/gpt-5-nano"),
  prompt: "Write a concise summary of Phaseo Gateway.",
});

console.log(result.text);
console.log(result.providerMetadata);

With chat history

import { phaseo } from "@phaseo/ai-sdk-provider";
import { generateText } from "ai";

const result = await generateText({
  model: phaseo("openai/gpt-5-nano"),
  messages: [
    { role: "system", content: "You are a terse assistant." },
    { role: "user", content: "Give me three bullet points on retrieval augmentation." },
  ],
});

console.log(result.text);
console.log(result.providerMetadata);

Per-model settings

import { phaseo } from "@phaseo/ai-sdk-provider";
import { generateText } from "ai";

const result = await generateText({
  model: phaseo("openai/gpt-5-nano", {
    temperature: 0.2,
    topP: 0.9,
    maxTokens: 300,
  }),
  prompt: "Draft a release note for an API update.",
});

console.log(result.text);
console.log(result.providerMetadata);

Prompt vs messages

Use prompt for quick single-turn requests.
Use messages for multi-turn context and role control.
Keep model IDs dynamic by querying /v1/models (see Model Discovery).
