Two days ago, GPT-6 Astra broke a yet unsolved German Army Enigma message from 1941. Amazingly Astra was able to autonomously:
- Search historical archives
- Compare uncertain letters
- Find contextual clues
- Build an Enigma simulator
- Write cryptanalysis code
- Run parallel experiments
- Test competing keys
- Recover the plaintext
- Cross-check the results

GPT-6 Astra Extra High found the solution in roughly 10 hours.
“Please specify the route of march. I am in Rosenow, Rosenow. Immediate reply by radio.”

I spent 99x more effort on building the website to describe the challenge and solution than any of my efforts on breaking the code. Astra also did all of the heavy lifting on building the site too! I just iterated with it over a few days.

Special shoutout to Frode Weierud at cryptocellar.org for being so kind to review the results and provide feedback so quickly.

Check out the website to learn more about the challenge, see a virtual Enigma machine, in three.js no less.

autonomously burned 70% of your weekly quota to read 'immediate reply by radio'
the original bletchley park crew did this with pencil and tea and no million dollar cluster
I am wondering what other types of unresolved topics we can throw Astra.. unresolved crimes?
actually that’s a great question to ask Astra. verification is the challenge, problem selection is half the battle
thank you! I didn't expect after i entered the following that I would actually see it finish.
/goal don't stop working until you solve the problem
With Pro account it used 70% of my weekly, 650 million tokens.
without reproducible logs and original ciphertext, this is a demo claim, not cryptanalysis evidence
all of the logs and everyone to reproduce is on the website to download. i also sought and received validation by an expert before posting.
I wonder how it would have done on the Rosetta Stone? or how quickly.
great question. hard to say… i’m sure all of the data regarding the rosetta stone has been baked into nearly all frontier models so it would be difficult to attempt…
the problem was chosen because at that point it hadn’t been broken. Of course now that the code is broken a time traveler to 1941 would know about troop movements :-)
Fascinating, I had no idea there were still Enigma messages that hadn’t been cracked

emotional qualities of watching codex one-shot some rust code after thirty minutes of iteration
The media could not be played.
Copied that prompt into ChatGPT attacked this, here are the results “Plate 4347 — THE GIANT GOES DOWN — proposed by Theodore Giesecke — Houston, Texas, Monday, April 7, 1919”
This is a great post. It makes sense that we should use AI tools to have a go at these old messages. I think there is a lot we can do here more generally joining the dots on archived materials.
Bletchley Park is struggling financially so good to keep people interested in this
I bet it didn’t, I bet it stole or used historical research to figure out a code that everyone else didn’t deem important now the war was won !
bletchley park used thirty thousand to break german navy enigma. one model just solved a 1941 message in ten hours.
this is so dope!
reminds me of the parallel timelines between ww2 and "future" present day in
Amazing. When I visited Bletchley Park years ago I had the privilege of talking to Tony Sale.
Fun fact: Polish mathematicians Marian Rejewski, Jerzy Różycki, and Henryk Zygalski broke the German Enigma cipher in late 1932. The symbolic date is December 31, 1932 - that was when Rejewski deciphered the first message encrypted using the military version of the Enigma.
Interesting! I naively thought all Enigma messages were already translated...
