1
00:00:03,000 --> 00:00:07,000
It has never played before, so it moves at random.

2
00:00:07,000 --> 00:00:10,000
When a game ends, what happened is saved to a shared memory.

3
00:00:10,000 --> 00:00:14,000
The same level and starting position, after 431,173 decisions.

4
00:00:14,000 --> 00:00:18,000
Every move now comes from what earlier games remembered.

5
00:00:18,000 --> 00:00:23,000
128 games play at once and write to the same memory.

6
00:00:23,000 --> 00:00:28,000
The curve follows eight games that always choose the best-scoring move.

7
00:00:28,000 --> 00:00:32,000
Venn embeds each screen with EmbeddingGemma 2 and looks up similar moments.

8
00:00:32,000 --> 00:00:35,500
For each move, it averages how those moments turned out.

9
00:00:35,500 --> 00:00:41,000
At quarter speed: it returns the move with the best record, and the game plays it.

10
00:00:41,000 --> 00:00:44,000
The game client makes one call for a batch of 128 screens.

11
00:00:44,000 --> 00:00:47,000
The game owns the memory store, and Venn reads it through an adapter.

12
00:00:47,000 --> 00:00:52,000
Another recorded round with the same memory.

13
00:00:55,000 --> 00:01:00,000
This round finishes with 6 kills.

14
00:01:00,000 --> 00:01:04,000
One more call compiles the memory into a small head.

15
00:01:04,000 --> 00:01:08,000
The head has 49,000 parameters and fits in 200 kilobytes.

16
00:01:08,000 --> 00:01:11,500
Same level, with the memory switched off.

17
00:01:11,500 --> 00:01:15,000
The head alone picks every move.

18
00:01:20,500 --> 00:01:26,000
This round finishes with 13 kills.

19
00:01:26,000 --> 00:01:32,000
The whole loop, including the game itself, runs on one GPU.

20
00:01:32,000 --> 00:01:36,000
Across 250 scored games, the head averaged 8.4 kills per game.

21
00:01:36,000 --> 00:01:39,000
The memory it learned from averaged 6.2.

22
00:01:39,000 --> 00:01:42,000
A memory of raw pixels averaged 4.9, and random moves averaged 1.3.

23
00:01:42,000 --> 00:01:45,000
The embedding model is pretrained and frozen.

24
00:01:45,000 --> 00:01:48,000
The head is the only trained part.
