1. The Broken Promise of “Fire-and-Forget” AI

The first wave of generative AI tools operated on a simple, seductive promise: describe a task, and a powerful model will deliver a finished result. This “magic wand” paradigm proved that modern LLMs could generate high-quality code, reports, and analyses. Yet for any professional engaged in complex, evolving work, the magic quickly faded.

The limitations revealed themselves:

🔴 Statelessness
Each interaction started from a blank slate, ignorant of past work. Every conversation was a new beginning. The AI had no memory of your project, your preferences, or your previous iterations. You were trapped in an endless cycle of re-explaining context.

🔴 Opacity
The AI worked in a black box, offering no visibility into its process. You submitted your request and waited. No progress updates. No intermediate results. No ability to see if the AI was on the right track until the final—often flawed—result was delivered.

🔴 Rigidity
There was no way to intervene, course-correct, or tweak requirements mid-flight. Made a small mistake in your prompt? Want to adjust based on early results? Too bad. Your only option was to start over from scratch, wasting time and tokens.

🔴 Unsustainable Economics
Relying exclusively on the most powerful models made continuous use prohibitively expensive. Using GPT-4 or Claude for every task—from simple formatting to complex reasoning—burned through budgets. There was no intelligent routing based on task complexity.

These tools treated work as a single transaction. But real work is a process—an iterative dialogue that unfolds over time. This fundamental disconnect is the problem Viber was built to solve.

2. Learning from the Vanguard: Karpathy & Cursor

Two key developments pointed toward a more effective paradigm.

First, Andrej Karpathy coined the term “vibe coding,” capturing a new mode of interaction:

This captured a profound shift from rigid programming to a fluid, conversational collaboration with an AI. It was a glimpse of a future where intent could be translated into results without deep technical ceremony.

Second, Cursor demonstrated a commercially successful application of this “vibe.” Its success wasn’t magic; it was a masterful act of integration. By embedding a capable LLM inside a mature, extensible platform (VS Code), it created a tight feedback loop between human and AI within a persistent, familiar environment.

The lesson is clear: the next breakthrough isn’t a bigger model, but a better architecture for collaboration.

Note: While Viber draws inspiration from Cursor’s collaborative approach, our focus is specifically on building a robust multi-agent engine rather than a complete product like Cursor. Creating a full IDE or editor integration would require extensive product-level features beyond the scope of our multi-agent framework. Viber is designed to be the powerful engine that could power such products, while remaining focused on its core strength: orchestrating intelligent agent collaboration.

3. Defining the Ideal Collaborator

What is the ideal role for an AI system in professional work?

Science fiction has given us powerful archetypes. We are not building a simple tool, nor an autonomous overlord. Instead, our vision is an AI that embodies the spirit of fiction’s most effective collaborators:

J.A.R.V.I.S.

Witty omniscience with perfect timing

Alfred

Steadfast loyalty and anticipatory service

TARS

Pragmatic competence with adjustable personality

These characters embody the perfect AI collaborator:

Omniscient yet Deferential: They possess vast knowledge but always serve the human’s strategic intent. They advise, they don’t command.
Context-Aware: They remember every past project, preference, and conversation, making each new interaction instantly productive.
Transparent: They can always explain what they are doing and why, providing clarity and building trust.
Proactive yet Controllable: They can anticipate needs and perform complex tasks, but the human can always intervene, tweak the plan, or hit the “stop” button.

While their personalities differ—from a witty AI to a dutiful butler to a pragmatic robot—they share one defining trait: they make their human partners exponentially more effective. This is the “vibe” we are chasing. The Viber philosophy is not just an abstract idea; it is a pragmatic engineering roadmap for building our own indispensable partner for creation.

4. The Three Workflows of Knowledge Creation

Instead of building a generic framework, Viber is optimized for the three fundamental workflows that encompass most professional knowledge work. Each has a distinct rhythm and requires a tailored collaborative experience.

From Idea to Document This workflow covers the creation of complex

documents: research papers, technical documentation, market analyses, legal briefs. It’s an iterative process of outlining, drafting, sourcing evidence, revising, and formatting. Human Role: - Provides core arguments and critical judgment - Sets the strategic direction and key insights - Reviews and approves final content Agent Role: - Assists with research and fact-finding - Drafts initial content based on guidance - Ensures consistency and formatting Example Use Cases: - Academic research papers

Technical documentation - Market analysis reports - Legal briefs and contracts

By recognizing these distinct patterns, Viber provides tailored templates, prompts, and toolsets that feel native to the task at hand.

5. The Architectural Pillars of Viber

To power these workflows, the Viber framework is built on four core architectural pillars.

Pillar 1: Memory & Workspace — The Persistent Brain

A Viber project relies on two complementary stores that provide a durable, shared context for both human and AI:

📁 The Workspace: This is the auditable, human-readable file system. It contains all project artifacts—source code, drafts, reports, logs—and serves as the “source of truth.” It’s designed to be versioned with Git and navigated with standard tools like VS Code.
🧠 The Memory: This is a high-performance semantic store (e.g., a vector database) that acts as the AI’s “long-term memory.” It contains distilled knowledge, key decisions, conversation history, and indexed references to workspace artifacts.

The workspace is where work lives. The memory is how XAgent understands that work, allowing it to retrieve relevant context instantly without being overwhelmed by the entire project history. This duality enables true, resumable sessions - just call XAgent.resume(agent_id) and continue where you left off.

Pillar 2: The Transparent Feedback Loop — The Collaborative Nervous System

The core of the Viber experience is its transparent, interruptible feedback loop. Long-running tasks are not opaque, “fire-and-forget” processes. Instead, Viber streams the agent’s internal monologue, tool usage, and intermediate results in real time.

This provides critical “jump-in moments” for the human collaborator, who can:

Tweak the direction by providing new instructions or priorities.
Correct a flawed assumption before it cascades into wasted work.
Abort a failing path to save time and costly tokens.

This “open-heart surgery” on a running task is essential for building trust and ensuring that the human remains the ultimate pilot of the project, not a mere passenger.

Pillar 3: The Cost-Aware Orchestrator — The Economic Engine

A professional-grade framework cannot ignore economics. Viber is architected around the reality of a tiered LLM market. The Orchestrator is the intelligent component that routes tasks to the most appropriate model, balancing capability with cost.

Routine Tasks (e.g., formatting, summarization, basic code generation) are sent to fast, inexpensive models like DeepSeek or Qwen.
Complex Reasoning (e.g., architectural planning, strategic analysis) is escalated to high-capability models like Claude or GPT-4.

This dynamic, cost-aware routing makes continuous, long-term AI collaboration economically viable, transforming it from a novelty into a sustainable business process.

Pillar 4: XAgent as Primary Interface — The “Just Talk to X” Experience

✨ To truly deliver on the Viber philosophy, the framework must be immediately accessible. XAgent (“X” for short) is your primary interface to Viber - the AI collaborator you interact with directly.

// This is all you need
import { XAgent } from "viber";

const xAgent = await XAgent.start("Build a documentation site");
const stream = await xAgent.streamText({
  messages: [{ role: "user", content: "Make it searchable" }],
});

🚀 This embodies the principle of “fast start, full control.” You’re productive in seconds, not minutes. When you need specific behaviors, you can configure X’s team through simple YAML files, never touching the orchestration code.

6. The Simplicity of X: Your AI Collaborator

✨ The ultimate expression of the Viber philosophy is its interface: X

Where other frameworks expose complex abstractions—projects, orchestrators, task queues—Viber gives you a single point of contact.

Start a collaboration

const xAgent = await XAgent.start("Build a web scraper");

Work together

await xAgent.streamText({
  messages: [{ role: "user", content: "It should handle pagination" }],
});
await xAgent.streamText({
  messages: [{ role: "user", content: "Add rate limiting to be respectful" }],
});

Resume anytime

const xAgent = await XAgent.resume("space_abc123");
await xAgent.streamText({
  messages: [{ role: "user", content: "Now make it output JSON" }],
});

🎯 This radical simplicity—hiding projects, tasks, and plans as internal implementation details—transforms AI collaboration from a technical endeavor into a natural conversation. You don’t manage a project; you work with X.

7. Conclusion: Beyond Automation, Towards Augmentation

Viber is a bet against pure automation

It is a framework founded on the belief that the most significant breakthroughs will come from augmenting human experts, not attempting to replace them.

Persistent

Your work continues across sessions

Transparent

See and control every decision
