Hardware-isolated execution environments for AI agents

Installation

npm install buildfunctions

Quick Start

1. Create an API Token

Get your API token at buildfunctions.com/settings

2. CPU Function

import { Buildfunctions, CPUFunction } from 'buildfunctions'

const buildfunctions = await Buildfunctions({ apiToken: process.env.BUILDFUNCTIONS_API_TOKEN })

const deployedFunction = await CPUFunction.create({
  name: 'my-cpu-function',
  code: './cpu_function_code.py',
  language: 'python',
  memory: 128,
  timeout: 30
})

console.log('Endpoint:', deployedFunction.endpoint)

await deployedFunction.delete()

3. CPU Sandbox

import { Buildfunctions, CPUSandbox } from 'buildfunctions'

const buildfunctions = await Buildfunctions({ apiToken: process.env.BUILDFUNCTIONS_API_TOKEN })

const sandbox = await CPUSandbox.create({
  name: 'my-cpu-sandbox',
  language: 'python',
  code: '/path/to/code/cpu_sandbox_code.py',
  memory: 128,
  timeout: 30,
})

const result = await sandbox.run()
console.log('Result:', result)

await sandbox.delete()

4. GPU Function

import { Buildfunctions, GPUFunction } from 'buildfunctions'

const buildfunctions = await Buildfunctions({ apiToken: process.env.BUILDFUNCTIONS_API_TOKEN })

const deployedFunction = await GPUFunction.create({
  name: 'my-gpu-function',
  code: '/path/to/code/gpu_function_code.py',
  language: 'python',
  gpu: 'T4',
  vcpus: 30,
  memory: "50000MB",
  timeout: 300,
  requirements: ['transformers==4.47.1', 'torch', 'accelerate'],
})

console.log('Endpoint:', deployedFunction.endpoint)

await deployedFunction.delete()

5. GPU Sandbox with Local Model

import { Buildfunctions, GPUSandbox } from 'buildfunctions'

const buildfunctions = await Buildfunctions({ apiToken: process.env.BUILDFUNCTIONS_API_TOKEN })

const sandbox = await GPUSandbox.create({
  name: 'my-gpu-sandbox',
  language: 'python',
  memory: 10000,
  timeout: 300,
  vcpus: 6,
  code: './gpu_sandbox_code.py',
  model: '/path/to/models/Qwen/Qwen3-8B',
  requirements: "torch"
})

const result = await sandbox.run()
console.log('Result:', result)

await sandbox.delete()

The SDK is currently in beta.
