Minecraft now. Hytale next.

Today

Minecraft, Java edition

Cog joins your world like a player, on a properly hosted server. Which is why joining a Cubelings world needs nothing more than an ordinary, unmodified copy of the game — the same one your friends already have installed.

Working today

What they will build for you right now

None of this is a roadmap. Every one of these has been built in a real Minecraft world and then measured — the block counts read back out of the world, not taken from what the build thought it did.

• Whatever you describe — they design it themselves rather than picking from a list. Asked for a walk-in house shaped like SpongeBob they drew one and built it: 24,688 blocks, every one of them read back afterwards — and then Cog walked inside it, 14 blocks past the wall, rather than telling you it was walk-in. A pirate galleon out on the open sea came to 30,263.
• New games, loaded while you play — not a pitch to look at, a game to play on it. Ask for soccer and they lay the field and write the rules: goals that count, a scoreboard, pads that hand out snowballs, fireworks for the winner. Nine rules live on the running server in 1,641 ms, with nobody kicked and nothing to install. Then they set off every rule themselves to check it fires.
• Canyons and waterfalls — a gorge with terraced walls and banded rock, and water that falls off the rim into a pool that stays put.
• Lakes, hills and flat ground — a basin with a proper shoreline, raised ground with a natural profile, or a plot levelled to build on.
• Landmarks — pyramids with a chamber you can stand in, watchtowers with a stair that climbs one block a step, castle keeps with walls you can walk along.
• Places to live — houses with doors that open and lit interiors, and arenas that are fair at both ends, symmetric to the block.
• Roads and bridges — routes that read the ground they cross, and spans over open water with the deck raised clear of it.
• Rollercoasters — a loop of real track with a hill in it, powered rails to keep you moving, and a cart waiting at the station. Checked by putting a cart on it and measuring how far it gets.
• Real redstone — a hidden door wired block by block, verified opening and sealing at two, four and six blocks wide.
• Playing alongside you — mining, crafting, farming, fighting, fetching, and following you around.

Hytale entered Early Access in January 2026

Hytale is next on the list. It was designed for dedicated servers with a plugin system from day one, which is a genuinely different starting point to Minecraft. Getting the builder running there is real engineering work, not a shortcut we are assuming will just work — an early spike already proved that authoring and loading new server-side code can be fast and safe, which is the part that work will actually depend on.

Why it is not starting from scratch

The model never learns a game. The skills do.

When it plans "gather some wood, then build a road", it is reasoning about what you want — a route, a quantity, a material — not about one game's particular blocks. The part that is specific to a game is the layer underneath: the code that knows what a Minecraft repeater's facing means, or what the equivalent call looks like elsewhere. Swapping games means swapping that layer, not rebuilding everything on top of it.

Two things carry across without change: asking in plain language and having it work out the details, described in How it works, and the habit of checking its own result afterwards, described in Verification. Neither depends on which game is running underneath.

What stays the same either way

Nothing to install, whichever game it is

Whichever game is running, Cog lives on the server and players join with an unmodified client. Nothing changes on a player's machine, and nothing ever will.
