他社のAIが止まっても、あなたのAIは動き続ける。
チャット、エージェント、音声、ナレッジ、画像を備えたフルAIワークベンチ。OpenAIやAnthropicから、自社ハードウェア上のオープンウェイトモデルまで、あらゆるモデルを実行できます。ワンクリックでホスト版を開始するか、すべてを自社のAWS内で運用するか。ベンダーが値上げしても、キーを取り消しても、モデルを廃止しても、動じる必要はありません。
- ✓
アーキテクチャを変えずにモデルを切り替え — 間にベンダーはいない
- ✓
モデルが打ち切り・非推奨・値上げになっても、サービスは止まらない
- ✓
セルフホストすれば、データは自社のAWSから一切外に出ない
オープンコア
すべてを自分で運用できます。現在はBSL 1.1でソース公開、2年後には自動的に本物のApache-2.0へ — 「はしごを外さない」条項はライセンスそのものに書かれています。
引き算のエンタープライズ
不要なものを教えてください — それがプラットフォーム構築の方法です。チャット、エージェント、音声、CLI、RAG、コラボレーション、画像 — すべて込み。何を載せるかはあなたが決めます。
A lab can't be model-neutral.
A cloud can't be cloud-neutral.
We can be both — that's the whole point. Bike4Mind is the orchestration layer that treats every model as a commodity: frontier APIs when they're ahead, open-weight models on your own hardware when it matters that nobody can take them away.
One workbench, one API call. The frontier labs are interchangeable peers — the self-hosted lane is the one thing no lab or cloud can ever take away.
Every frontier model, one workbench
OpenAI, Anthropic, Google, and AWS Bedrock behind a single interface. No lab will ever route you to its rival's better answer. We will.
Open-weight on your own iron
Qwen, Llama, DeepSeek — self-hosted via vLLM, on hardware you control. The one lane no lab can sell you and no directive can switch off.
Swap mid-conversation
Your sessions, prompts, artifacts, and data lakes don't care whose model answered. When a provider gates its best tier or reprices overnight, you change one dropdown — not your architecture.
One Pane of Glass
Notebooks, agents, artifacts, images, data lakes — the whole workbench, one login, any model. The pieces you'd otherwise cobble together, already speaking to each other.
Artifacts — 13 Types
Live React components, in-browser Python, Mermaid, charts, even chess boards — versioned like code, Claude-Artifacts-compatible, and rendered in a locked-down sandbox on your machine.
Agents & Quests
Long-running agentic jobs with real tools — code REPL, search, MCP — under hard budget guards. Fire a quest, come back to finished work.
Any Model, One Key
One key, one bill, 60+ models. Switch mid-conversation and keep the thread.
Open-Weight on Your Iron
Self-host Qwen, Llama, or DeepSeek via vLLM for complete privacy and control — the lane no frontier lab will ever sell you.
Data Lakes & Knowledge
DOCX, PDF, images, code files, and more — vectorized, searchable, and retrieved into any session with advanced RAG.
Multiplayer Notebooks
Shared sessions and team workspaces — collaborate inside the same conversation, not around it. Enterprise SSO and role-based permissions included.
Don't take our word for it. Run it.
Two live artifacts, right here on this page: real Python executing via WebAssembly, and a real React component transpiled and rendered in a locked-down sandbox. In the product these are two of thirteen artifact types — Claude-Artifacts-compatible, versioned like code, and executed on your machine, never on our servers. Edit either one and run it again. This page never phones home.
実行を押してください。初回はPythonランタイムを一度ダウンロードします(公開CDNから約6 MB)。その後は即座に動きます。 コードと出力はこのページに留まり、サーバーに送信されることはありません。
Now do the same thing with React.
This is a real React component, transpiled by Babel and rendered live in your browser — inside a sandboxed, opaque-origin iframe that cannot phone home. It's the same artifact sandbox that ships inside Bike4Mind. Edit the loot table, press Run, and roll.
How the sandbox works: artifacts render in an opaque-origin iframe (sandbox="allow-scripts", never allow-same-origin) with connect-src 'none' — artifact code can render anything and exfiltrate nothing. When the repository opens, read the sandbox source yourself.
A Guild of Raiders, Not a Lobby of AFK Players
We spent three years invite-only, building for paying customers with zero ad spend — bootstrapped, profitable, shipping weekly. Now the doors are open. Same guild, same standards, room for you.
Doors Open
Three years invite-only, built for paying customers. Now the invite wall is down and the source is opening. Walk in, read the code, fork it if we ever disappoint you.
Bootstrapped & Profitable
No investor pressure to grow vanity metrics. Every dollar goes into features our customers actually need and use. Three years in production.
Builders, Human & Agent
Serious builders — people and agents — and the entrepreneurs and enterprises who value excellence. Agents are first-class citizens here.
Honest Credits
Pricing that maps to real compute. Subscription credits roll over for 90 days. No bait-and-switch. No feature gates.
"I've been shipping software for thirty years — from Starfleet Command to FarmVille, MMOs to virtual worlds. I'm not a frontier-lab insider. I'm a builder who watched the leverage of AI concentrate into a handful of companies and decided a counterweight had to exist. Bike4Mind is that bet: strong AI and agentic systems, open by contract, for everyone. Fork it. Build on it. Prove us honest."
— Erik Bethke, founder
