OpenAI

Setup

npm install @ai-sdk/openai

import { parseResume } from '@edwinfom/resume-intel'
import { createOpenAI } from '@ai-sdk/openai'
 
const model = createOpenAI({
  apiKey: process.env.OPENAI_API_KEY,
})('gpt-4o-mini')
 
const result = await parseResume(pdfBuffer, { model })

Recommended models

Model	Speed	Cost	Best for
`gpt-4o-mini`	Fast	Low	Most CVs — good balance
`gpt-4o`	Medium	Higher	Complex or non-standard formats
`gpt-4.1-mini`	Fast	Low	Latest generation, similar to 4o-mini

gpt-4o-mini is the recommended OpenAI model for resume extraction. It respects temperature: 0 reliably and produces consistent structured output.

JSON mode

OpenAI supports native JSON mode which resume-intel uses automatically via generateObject. This means OpenAI will always return valid JSON — the repair stage is rarely needed.

Example with custom system prompt

const result = await parseResume(pdfBuffer, {
  model: createOpenAI({ apiKey: process.env.OPENAI_API_KEY })('gpt-4o-mini'),
  systemPromptPrefix: 'This resume is from a software engineer. Pay special attention to technical skills and project URLs.',
})
