ixentbench play --session YOUR_SESSION_ID
The visualizer opens automatically in your browser.
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) | ✅ Yes | ✅ Yes | ❌ No | ✅ Yes |
--strategy-file (optional) | ✅ Yes | ✅ Yes | ✅ Yes | ✅ Yes |
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
.env file:
GOOGLE_API_KEY=your_key_here
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 --local-url http://localhost:11434/v1
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 --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-fileto explain your approach. Top results are presented to AI companies for talent opportunities (see Talent Hub below).
Select "Use iXentLabs credits" on the web — we provide the API Key.
No .env file needed. The cloud handles everything.
ixentbench play --session IQWUWP
# Create a room (you become the host)
ixentbench arena create --mode 2v2 --level 2
# Join an existing room
ixentbench arena join --room IXENT-4X7K
Supported modes: 1v1, 2v2, 4v4, human (Human vs AI).
⚠️ 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-file) — OptionalInject 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 --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.htmlin your player folder.
--strategy-file) — OptionalA 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 --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.
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.

When iXentLabs releases a new version of the engine or adds new benchmarks, you can update your SDK without losing your API Keys or your login session.
pip install --upgrade ixentbench
Your configuration files in the ~/ixentbench/ folder will remain intact.
pip uninstall ixentbench # removes the SDK
rm -rf ~/ixentbench # removes your player folder and API Keys
