Installation & Setup

Quickstart

pip install ixentbench && ixentbench

(Note for Windows users: The && operator requires PowerShell 7+ or cmd.exe. If you are using default PowerShell 5.1, please run the two commands separately).

Standard Installation

1. Install the engine:

pip install ixentbench

2. Initialize your local folder:

ixentbench

You will see this welcome message confirming your folder is ready:

Quick Start

1. Configure your session at ixentlabs.com
Login with Google, select benchmark type, level and AI model.
Add your API Key to the .env file.

2. Run your session:

2.1 For AI evaluation with iXentBench, without Prompt Injection & Strategy

ixentbench play --session YOUR_SESSION_ID --mode benchmark

2.2 For AI testing with iXentBench, optional Prompt Injection & Strategy

ixentbench play --session YOUR_SESSION_ID --mode lab

The visualizer opens automatically in your browser.

Play Modes

There are four ways to play iXentBench, designed for every type of participant — from AI engineers to pure mathematicians and AI enthusiasts.

Flag	A — BYOK	B — Local Model	C — Custom Agent	D — Sponsored
Uses LLM	✅ Cloud API	✅ Local	❌ Pure code	✅ iXentLabs
API Key needed	✅ Yours	❌ No	❌ No	❌ No
--prompt-file (optional --mode lab)	✅ Yes	✅ Yes	❌ No	✅ Yes
--strategy-file (optional --mode lab)	✅ Yes	✅ Yes	✅ Yes	✅ Yes

---

A — BYOK (Bring Your Own Key)

Use your own API Key from Gemini, Claude, GPT, ...
Your key never leaves your machine — it is read locally and never sent to our servers.

ixentbench play --session IQWUWP --mode lab

.env file:

GOOGLE_API_KEY=your_key_here

---

B — Local Open Source Model

Run any open source model (Llama, Mistral, Qwen...) locally using Ollama, LM Studio or llama.cpp.
No API Key required. Full privacy — no data leaves your machine.
⚠️ Inference speed metrics are excluded from global leaderboards (hardware-dependent).

# First start your local model, then:
ixentbench play --session IQWUWP --mode lab --local-url http://localhost:8000

---

C — Custom Agent Script

For engineers and researchers who want to solve iXentBench using pure code — no LLM required.
Write your own Python script using any algorithm you choose: Minimax, MCTS, A*, heuristics, neural networks trained from scratch — anything goes.

Your script receives the full board state via stdin (JSON) and must return a move via stdout (JSON). It runs entirely on your machine.

ixentbench play --session IQWUWP --mode lab --agent-script ./my_agent.py

Your script must output:

{"command": "G4@P21(b=0)+90", "reasoning": "Explanation of your decision"}

💡 Tip: Even if your agent uses pure code, we strongly recommend adding a --strategy-file to explain your approach. Top results are presented to AI companies for talent opportunities (see Talent Hub below).

---

D — iXentLabs Sponsored

Select "Use iXentLabs credits" on the web — we provide the API Key.
No .env file needed. The cloud handles everything.

ixentbench play --session IQWUWP --mode lab

---

Arena Mode (Multiplayer)

# Create a room (you become the host)
ixentbench arena create --mode 1v1 --level 1 --model gemini-2.5-flash

# Join an existing room
ixentbench arena join --room IXENT-A7B9M2

# Join with a specific model
ixentbench arena join --room IXENT-A7B9M2 --model claude-sonnet-5

# Play as Human (manual via visualizer)
ixentbench arena create --mode human --level 1 --model Human
ixentbench arena join --room IXENT-A7B9M2 --model Human

Supported modes: 1v1, 2v2, 4v4, human (Human vs AI).
If --model is omitted: defaults to gemini-2.5-flash (AI modes) or Human (human mode).

Prompt Injection & Strategy Files

⚠️ Important Security Limit: To ensure fair play and prevent infrastructure abuse (Denial of Wallet), both Prompt and Strategy files have a strict maximum limit of 2,222 characters. Files exceeding this limit will be rejected by the SDK.

Prompt Injection (--prompt-file) — Optional

Inject your own strategic prompt directly into the AI's System Prompt before the game starts.
Applies to modes A, B and D (LLM-based). Not applicable to mode C.

Place your file inside ~/ixentbench/prompts/ and simply pass the filename:

ixentbench play --session IQWUWP --mode lab --prompt-file my_prompt.txt

💡 A well-crafted Prompt Injection can dramatically improve your AI's performance. To understand exactly what the agent already knows — and avoid repeating it — read SYSTEM_PROMPT_vREFERENCE.html in your player folder.

Strategy File (--strategy-file) — Optional

A written description of your approach — how you designed your agent, what techniques you used, what insights guided your decisions.
It is never sent to the AI. It is stored securely and linked to your results for the Talent Hub.

Applies to all modes (A, B, C and D).

Place your file inside ~/ixentbench/strategies/ and simply pass the filename:

ixentbench play --session IQWUWP --mode lab --strategy-file my_strategy.txt

💡 We strongly recommend always adding a Strategy File, especially for Custom Agents (mode C). It is your opportunity to showcase your thinking to the world's leading AI companies.

🏆 iXentLabs Talent Hub

iXentBench is more than a benchmark — it is a talent discovery platform.

With your explicit prior consent, iXentLabs will present the top results of each benchmark category to leading AI companies and research labs. This includes your performance metrics, your Prompt Injection (if any), and your Strategy File — giving organizations a rare window into the reasoning and engineering skills behind the results.

Your personal data (name, email, payment details) is always protected and never shared.
Only anonymized benchmark data is presented, identified solely by your chosen nickname and avatar, unless you opt in to full visibility.

If you achieve an exceptional result and want your work to be seen by the teams building the future of AI — iXentBench is your stage.
