NeuroLink

The pipe layer for the AI nervous system.

AI intelligence flows as streams — tokens, tool calls, memory, voice, documents. NeuroLink is the vascular layer that carries these streams from where they are generated (LLM providers: the neurons) to where they are needed (connectors: the organs).

import { NeuroLink } from "@juspay/neurolink";

const pipe = new NeuroLink();

// Everything is a stream
const result = await pipe.stream({ input: { text: "Hello" } });
for await (const chunk of result.stream) {
  if ("content" in chunk) {
    process.stdout.write(chunk.content);
  }
}

• 🧠 Gemini 3 Native Multi-turn Tool Calling — Fixed multi-step agentic tool calling for Gemini 3 models on Vertex AI. The native @google/genai path now correctly replays thoughtSignature as a sibling field on each functionCall part, groups parallel tool calls by stepIndex, enforces a 5-minute default timeout on the generate path, and surfaces silent timeouts as proper TimeoutError instead of empty responses. Multi-execution session overlap (where continueOrchestratorWorkflow restarts the loop on the same sessionId) is addressed by an executionId per invocation as a composite grouping key — this prevents tool calls from two different executions colliding into the same Gemini model turn and causing the model to return 0 function calls.

// Automatically chunk, embed, and search documents
const result = await neurolink.generate({
  input: { text: "What are the key features mentioned in the documentation?" },
  rag: {
    files: ["./docs/guide.md", "./docs/api.md"],
    chunkSize: 512,
    topK: 5,
  },
});

Structured Output with Zod:

import { z } from "zod";

const schema = z.object({
  name: z.string(),
  age: z.number(),
  email: z.string().email(),
});

const result = await neurolink.generate({
  input: {
    text: "Extract user info: John Doe, 30 years old, john@example.com",
  },
  schema,
  output: { format: "json" },
});

// Parse the structured JSON from result.content
const parsed = schema.parse(JSON.parse(result.content));
console.log(parsed); // { name: "John Doe", age: 30, email: "john@example.com" }

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

Revolutionary Interactive CLI

NeuroLink's CLI goes beyond simple commands - it's a full AI development environment:

Why Interactive Mode Changes Everything

Feature	Traditional CLI	NeuroLink Interactive
Session State	None	Full persistence
Memory	Per-command	Conversation-aware
Configuration	Flags per command	/set persists across session
Tool Testing	Manual per tool	Live discovery & testing
Streaming	Optional	Real-time default

Live Demo: Development Session

$ npx @juspay/neurolink loop --enable-conversation-memory

neurolink > /set provider vertex
✓ provider set to vertex (Gemini 3 support enabled)

neurolink > /set model gemini-3-flash-preview
✓ model set to gemini-3-flash-preview

neurolink > Analyze my project architecture and suggest improvements

✓ Analyzing your project structure...
[AI provides detailed analysis, remembering context]

neurolink > Now implement the first suggestion
[AI remembers previous context and implements suggestion]

neurolink > /mcp discover
✓ Discovered 58 MCP tools:
   GitHub: create_issue, list_repos, create_pr...
   PostgreSQL: query, insert, update...
   [full list]

neurolink > Use the GitHub tool to create an issue for this improvement
✓ Creating issue... (requires HITL approval if configured)

neurolink > /export json > session-2026-01-01.json
✓ Exported 15 messages to session-2026-01-01.json

neurolink > exit
Session saved. Resume with: neurolink loop --session session-2026-01-01.json

Session Commands Reference

Command	Purpose
/set <key> <value>	Persist configuration (provider, model, temperature)
/mcp discover	List all available MCP tools
/export json	Export conversation to JSON
/history	View conversation history
/clear	Clear context while keeping settings

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 json

# RAG: Ask questions about your docs (auto-chunks, embeds, searches)
npx @juspay/neurolink generate "What are the key features?" \
  --rag-files ./docs/guide.md ./docs/api.md --rag-strategy markdown

# Claude proxy + local OpenObserve dashboard
npx @juspay/neurolink proxy setup
npx @juspay/neurolink proxy telemetry setup
npx @juspay/neurolink proxy status --format json

import { NeuroLink } from "@juspay/neurolink";

const neurolink = new NeuroLink({
  conversationMemory: {
    enabled: true,
  },
  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
      "./report.xlsx", // Auto-detected as Excel
      "./config.json", // Auto-detected as JSON
      "./diagram.svg", // Auto-detected as SVG (injected as text)
      "./app.ts", // Auto-detected as TypeScript code
    ],
  },
  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);

// RAG: Ask questions about your documents
const answer = await neurolink.generate({
  input: { text: "What are the main architectural decisions?" },
  rag: {
    files: ["./docs/architecture.md", "./docs/decisions.md"],
    strategy: "markdown",
    topK: 5,
  },
});
console.log(answer.content); // AI searches your docs and answers

Gemini 3 with Extended Thinking

import { NeuroLink } from "@juspay/neurolink";

const neurolink = new NeuroLink();

// Use Gemini 3 with extended thinking for complex reasoning
const result = await neurolink.generate({
  input: {
    text: "Solve this step by step: What is the optimal strategy for...",
  },
  provider: "vertex",
  model: "gemini-3-flash-preview",
  thinkingConfig: {
    thinkingLevel: "medium", // Options: "minimal", "low", "medium", "high"
  },
});

console.log(result.content);
