globe_ai 1.0.3

A Dart-first package for interacting with large language models (LLMs).

🧠 globe_ai

globe_ai is a Dart-first package for interacting with large language models (LLMs) like OpenAI’s GPT series.

✨ Features

• 📝 generateText — basic prompt or messages based text generation

• 📡 streamText — stream text responses as they’re generated

• 🧱 generateObject — validate structured JSON output against a schema

• 🌊 streamObject — stream and validate structured data

🚀 Installation

Install Globe Runtime

You can install globe runtime using either of these approaches.

• Using Globe CLI.

  If you have Globe CLI installed locally, you can run globe runtime install.

• Adding Manually to your Environment

  Download the libglobe_runtime dynamic library for your Platform from Github Release Pages and place it in ~/.globe/runtime/ directory.

Setup

• Add dependency

dependencies:
  globe_ai: ^<latest-version>

• Configure your model provider (e.g. OpenAI, Google Generative AI):

final model = openai('gpt-4o');

or

final model = google('gemini-2.0-flash');

Usage

🔹 Text Generation

final result = await generateText(
  model: openai.chat('gpt-4o'),
  prompt: 'What is the capital of Ghana?',
);
print(result);

or

final textWithPdf = await generateText(
  model: openai.chat('gpt-4o', user: 'Chima'),
  messages: [
    OpenAIMessage(
      role: 'user',
      content: [
        OpenAIContent.text('What is the title of this book?'),
        OpenAIContent.file(
          File('bin/test_doc.pdf'),
          mimeType: 'application/pdf',
        ),
      ],
    ),
  ],
);
print(textWithPdf);

🔹 Streaming Text

final stream = streamText(
  model: openai('o4-mini'),
  prompt: 'Describe the Mission burrito vs SF burrito debate.',
);

await for (final chunk in stream) {
  stdout.write(chunk);
}

🔹 Structured Object Generation

final schema = l.schema({
  'recipe': l.schema({
    'name': l.string(),
    'ingredients': l.list(validators: [
      l.schema({'name': l.string(), 'amount': l.string()}),
    ]),
    'steps': l.list(validators: [l.string()]),
  })
});

final result = await generateObject<Map<String, dynamic>>(
  model: openai('gpt-4.1'),
  prompt: 'Generate a lasagna recipe.',
  schema: schema,
);

print(result['recipe']['name']);

🔹 Streaming Structured Objects

final resultStream = streamObject<Map<String, dynamic>>(
  model: openai('gpt-4.1'),
  prompt: 'Generate a lasagna recipe.',
  schema: schema,
);

await for (final chunk in resultStream) {
  print(chunk); // Validated partial output
}
