Enterprise AI development platform with unified provider access, production-ready tooling, and an opinionated factory architecture. NeuroLink ships as both a TypeScript SDK and a professional CLI so teams can build, operate, and iterate on AI features quickly.
🧠 What is NeuroLink?
NeuroLink is the universal AI integration platform that unifies 12 major AI providers and 100+ models under one consistent API.
Extracted from production systems at Juspay and battle-tested at enterprise scale, NeuroLink provides a production-ready solution for integrating AI into any application. Whether you're building with OpenAI, Anthropic, Google, AWS Bedrock, Azure, or any of our 12 supported providers, NeuroLink gives you a single, consistent interface that works everywhere.
Why NeuroLink? Switch providers with a single parameter change, leverage 64+ built-in tools and MCP servers, deploy with confidence using enterprise features like Redis memory and multi-provider failover, and optimize costs automatically with intelligent routing. Use it via our professional CLI or TypeScript SDK—whichever fits your workflow.
Where we're headed: We're building for the future of AI—edge-first execution and continuous streaming architectures that make AI practically free and universally available. Read our vision →

💰 Smart Model Selection
NeuroLink features intelligent model selection and cost optimization:
Cost Optimization Features
- 💰 Automatic Cost Optimization: Selects cheapest models for simple tasks
- 🔄 LiteLLM Model Routing: Access 100+ models with automatic load balancing
- 🔍 Capability-Based Selection: Find models with specific features (vision, function calling)
- ⚡ Intelligent Fallback: Seamless switching when providers fail
# Cost optimization - automatically use cheapest model
npx @juspay/neurolink generate "Hello" --optimize-cost
# LiteLLM specific model selection
npx @juspay/neurolink generate "Complex analysis" --provider litellm --model "anthropic/claude-3-5-sonnet"
# Auto-select best available provider
npx @juspay/neurolink generate "Write code" # Automatically chooses optimal provider✨ Interactive Loop Mode
NeuroLink features a powerful interactive loop mode that transforms the CLI into a persistent, stateful session. This allows you to run multiple commands, set session-wide variables, and maintain conversation history without restarting.
Start the Loop
npx @juspay/neurolink loopExample Session
# Start the interactive session
$ npx @juspay/neurolink loop
neurolink » /set provider google-ai
✓ provider set to google-ai
neurolink » /set temperature 0.8
✓ temperature set to 0.8
neurolink » Tell me a fun fact about space
The quietest place on Earth is an anechoic chamber at Microsoft's headquarters in Redmond, Washington. The background noise is so low that it's measured in negative decibels, and you can hear your own heartbeat.
# Use "/" for CLI commands
neurolink » /generate "Draft a haiku"
...
# Use "//" to escape prompts starting with "/"
neurolink » //what is /usr/bin used for?
...
# Exit the session
neurolink » exitConversation Memory in Loop Mode
Start the loop with conversation memory to have the AI remember the context of your previous commands.
npx @juspay/neurolink loop --enable-conversation-memorySkip the wizard and configure manually? See docs/getting-started/provider-setup.md.
CLI & SDK Essentials
neurolink CLI mirrors the SDK so teams can script experiments and codify them later.
# Discover available providers and models
npx @juspay/neurolink status
npx @juspay/neurolink models list --provider google-ai
# Route to a specific provider/model
npx @juspay/neurolink generate "Summarize customer feedback" \
--provider azure --model gpt-4o-mini
# Turn on analytics + evaluation for observability
npx @juspay/neurolink generate "Draft release notes" \
--enable-analytics --enable-evaluation --format jsonimport { NeuroLink } from "@juspay/neurolink";
const neurolink = new NeuroLink({
conversationMemory: {
enabled: true,
store: "redis",
},
enableOrchestration: true,
});
const result = await neurolink.generate({
input: {
text: "Create a comprehensive analysis",
files: [
"./sales_data.csv", // Auto-detected as CSV
"examples/data/invoice.pdf", // Auto-detected as PDF
"./diagrams/architecture.png", // Auto-detected as image
],
},
provider: "vertex", // PDF-capable provider (see docs/features/pdf-support.md)
enableEvaluation: true,
region: "us-east-1",
});
console.log(result.content);
console.log(result.evaluation?.overallScore);Full command and API breakdown lives in docs/cli/commands.md and docs/sdk/api-reference.md.
