# BLACKBOX AI inside your editor.

Bring inline completions, chat-driven edits, and multi-agent execution directly into VS Code — without switching tools or breaking flow.

## What makes it powerful.

### Code Example

```typescript
import { NextRequest, NextResponse } from "next/server"
import { auth } from "@/lib/auth"

export async function POST(req: NextRequest) {
    const session = await auth()
    if (!session) return NextResponse.json({ error: "Unauthorized" }, { status: 401 })

const body = await req.json()

const result = await db.insert(tasks).values({
        title: body.title,
        userId: session.user.id,
        status: "pending",
        createdAt: new Date(),
    }).returning()

return NextResponse.json(result[0])
}
```

### Inline completions

Get intelligent code suggestions as you type. Completions are context-aware, drawing from your open files, imports, and project structure. Supports multi-line completions, function generation, and pattern-based suggestions.

```typescript
import { auth } from "@/lib/auth"

export async function POST(req: NextRequest) {
    const session = await auth()

const result = await db.insert(tasks).values({
        title: body.title,
        userId: session.user.id,
        status: "pending",
        createdAt: new Date(),
    }).returning()
}
```

### Chat-driven edits

Open the BLACKBOX chat panel and describe changes in natural language. Edits apply as inline diffs you can review before accepting.

```typescript
export async function handler(req, res) {
    const data = req.body
    const schema = z.object({
        email: z.string().email(),
        name: z.string().min(1),
    })
    const data = schema.parse(req.body)

const user = await db.users.create({ data })
    return res.json(user)
}
```

### Multi-agent execution

Run /multi-agent from the chat panel to dispatch tasks across BLACKBOX, Claude Code, Codex, and Gemini. The Chairman LLM picks the best result.

## Common Questions.

### HOW DO I INSTALL IT?

Search 'BLACKBOX AI' in the VS Code Extensions Marketplace and click Install — it takes one click. The extension has over 4.2 million installations and is designed to feel like a native VS Code feature.

### IS IT FREE?

The extension is free with basic features including inline completions and chat using Minimax-M2.5. Pro ($10/mo), Pro Plus ($20/mo), and Pro Max ($40/mo) unlock frontier and open-source models like Claude Opus-4.6, GPT-5.2, Llama, and Mistral, plus longer context windows.

### DOES IT WORK WITH OTHER EXTENSIONS?

Yes. BLACKBOX AI integrates cleanly with existing VS Code extensions, keybindings, and themes. It uses intuitive keyboard shortcuts and a clean UI designed to minimize conflicts with your existing workflow.

### WHAT LANGUAGES ARE SUPPORTED?

All languages supported by VS Code work with BLACKBOX AI. AI features are optimized for TypeScript, Python, Go, Rust, Java, C++, and all major frontend and backend frameworks.

### WHICH AI MODELS ARE AVAILABLE?

The extension provides access to frontier and open-source models including Claude Opus-4.6, GPT-5.2, Gemini-3, Grok-4, Llama, and Mistral. Model availability depends on your plan tier — free users get unlimited agent requests on Minimax-M2.5.

### HOW DOES MULTI-AGENT MODE WORK IN VS CODE?

Run `/multi-agent` from the chat panel to dispatch the same task to Blackbox, Claude Code, Codex, and Gemini simultaneously. A Chairman LLM evaluates each implementation and the results appear as selectable diffs you can compare and merge.

### IS MY CODE SENT TO EXTERNAL SERVERS?

Code context is sent securely over `TLS 1.3` encryption for AI processing. Enterprise plans support end-to-end encryption with zero-knowledge architecture, and on-premise deployment is available for organizations requiring full data sovereignty.
