Three directions — pick your vibe:
Three directions — pick your vibe:
function findUser(users, id) {
users.forEach(u => {
if (u.id === id) return u;
});
}The return exits the arrow callback, not findUser — and forEach ignores return values. Use find:
const findUser = (users, id) =>
users.find(u => u.id === id);It also stops at the first match instead of scanning the whole array.

Imagine rolling a ball at a hill that’s too tall to climb. Normally it rolls back. But tiny particles like electrons are a bit like waves — and sometimes a little of the wave leaks through the hill and the particle pops out the other side.
You can’t walk through a wall. Tiny particles sort of can — not by breaking it, but because they’re fuzzy. A particle isn’t in one exact spot; it’s spread out a little, and a tiny bit of that fuzz reaches past the wall. Every so often, the particle shows up there.
Think of a video-game ghost that sometimes glides through walls. Electrons aren’t ghosts, but at tiny sizes they follow different rules: there’s a small chance they appear on the other side of a barrier. The memory chip in your phone uses this every day!

FAQ
TunnelGPT includes 40+ models across text, code, image, video and audio — including the GPT, Claude, Gemini, DeepSeek, Llama, Mistral, Grok and Qwen families. We add new models as soon as they’re production-ready, usually within days of release.
Yes. Pick a different model from the switcher at any point and it continues with the full conversation history. You can also @mention a model to get a single reply from it without switching.
No. Your chats are never used to train models — ours or anyone else’s. Models receive only what they need to answer your message.
You can keep chatting with fast models, or upgrade to Pro for the full lineup. Free limits reset every day at midnight UTC.
API access is in private beta for Team workspaces. Once your workspace is live, request access from the admin console.
We open workspaces in waves so every model stays fast for everyone. Create an account to reserve yours — we’ll email you the moment it’s ready.
Journal
Starting today you can reserve a workspace in the AI superapp that puts every major model behind one chat. Here’s what’s in the first wave and how invites work.
Every model has a personality — strengths, blind spots and habits. The people getting the most out of AI stopped picking a favourite a long time ago.
Send a single prompt to up to four models at once and read the answers side by side. Rolling out to beta members today.
