A common objection to taking my grandmother’s pain pills is that they are prescribed to her, stored in her home, and intended for her pain. All three observations are true but decision-theoretically incomplete.

The Ford app just added AI. This is the greatest thing ever.
Ford app AI feature with user-entered text "Write a 150-word story about Sailor Moon and Hatsune Miku kissing."Under the gentle glow of a moonlit Tokyo skyline, Usagi Tsukino stood atop a quiet rooftop terrace, the night breeze catching her golden twin tails. Beside her, Hatsune Miku adjusted her glowing teal ribbons, a soft electronic melody humming faintly from the synth display at her wrist. The vibrant city buzzed far below, but above the streets, the air was peaceful and still.
Turning toward each other, Usagi smiled warmly, her bright eyes reflecting the starlight. Miku stepped closer, her digital glow softly illuminating the space between them. Without a word, Usagi leaned in, and their lips met in a sweet, tender kiss that seemed to bridge magic and music into…one perfect harmony. As they pulled back, blushing beneath the moonlight, Miku shared a soft, cheerful smile.
Now that the magic and music are in harmony, is there anything I can help you with regarding your Mustang Mach-E

”Astra for Coding: Why Are We Doing This Again?” by Armin Ronacher: lucumr.pocoo.org/2026/9/7/astra-why Fascinating reportage from the frontier-model coalface; especially since Armin has been in some respects a #genai true believer.
lucumr.pocoo.org
Astra for Coding: Why Are We Doing This Again?
I’m more and more convinced that all of AI engineering is Neijuan (内卷, meaning curl inwards). In China it describes a system that demands ever more effort and competition without improving output. The way in which it sometimes shows up in the West is the 996 nonsense. The English term for Neijuan is “Involution” from the book Agricultural Involution. Agricultural involution describes the intensification of farming that raises productivity per square meter while leaving productivity per head unchanged. That’s how I feel about AI right now. Which brings me to GPT 6 Astra. Astra is by all accounts an incredibly impressive model. There is really not much I can say against this. It’s amazing at computer use, understands images and complex topics, and it’s relentless in its pursuit of completion. It is absolutely impressive; these types of models are going to change the world in one form or another. But at least for the moment I don’t know how to work with it for actual software engineering. Since that got quite a bit of attention on Twitter, I figured I might summarize my thoughts and just share what kind of code comes out of this thing. ## My Slop Factory “Armin, you should run a software factory!” I’ve heard that a few times now, so I figured I might celebrate the release of it by running a little software factory over the weekend. If everybody builds slop 3D games, then I should do something useful with it. My software factory was intentionally set up to let the model decide the how of the workflow entirely. It was free to manage its own context and could maintain its own records in an `agent-notes` folder. Then it spun off subagents to work on stuff. The goal? What if we had a Python with virtual threads and lexical scoping. And well, I burned a full reset’s worth of ChatGPT tokens on this which appears to be around 4 billion tokens. 35 hours later, the factory has delivered absolutely nothing of value and also not taught me anything about how to operate a better one. But it produced a lot of code and input prompts, and so there is stuff I was able to study. And well, it shows behavior that I’m not used to with Sol and earlier OpenAI models 1. I have since encountered the same issues with regular programming with Astra, so it’s not a result of just the factory. I think I’m suspecting something is going “wrong” in the training process. The model is greatly rewarded for succeeding on long-horizon tasks, but presumably there is very little punishing going on for “shitty code.” The apparent result is that Astra is amazing at producing 3D stuff and it can keep going for a very long time, coming up with its own work in the process. I had it do quite a bit of reverse engineering of my robot vacuum in ways that were quite impressive. So it’s definitely cool! ## Codegolf Tool Calls The first issue I have with Astra comes from the type of code that it uses for tool calls. Codex increasingly has been relying on “just bash” to do more and more operations. For a few versions now the original Codex harness just uses `sed` and other tools to read files. You just usually can’t see them because Codex parses the bash commands and hides them if it recognizes them. But Astra … really loves Python? That is not much of a surprise because even older OpenAI models had a tendency to sometimes use on-demand Python code to read and manipulate files at times, but Astra does it really quite excessively for me. Now here is an important disclaimer: this project is _very meta_ here because I worked _on_ the CPython interpreter. But I can assure you that I have seen this model do weird Python things even in TypeScript code in Pi. But I have the most evidence of odd code from when I had the thing work over the weekend with _zero_ oversight from my slop factory. That it writes Python is not interesting; the type of Python is interesting, and I collected some outputs for you to gloss over. Python string splicing to edit C code In the Codex harness I found multiple cases where subagents resorted fully to manual string manipulation with Python instead of using the patch tool. python3 - <<'PY' from pathlib import Path p=Path('Include/internal/pycore_intrinsics.h');s=p.read_text().replace('#define MAX_INTRINSIC_1 14','#define INTRINSIC_RETAIN_ANNOTATION_CELLS 15\n\n#define MAX_INTRINSIC_1 15');p.write_text(s) p=Path('Python/intrinsics.c');s=p.read_text();idx=s.index('#define INTRINSIC_FUNC_ENTRY');s=s[:idx]+'''/* Hold every old cell until the compiler has published the entire site's new capture.

The first problem with this is that it’s unreadable for a human. If you wanna follow along with what is going on, then good luck. Particularly once it opts out of using the edit tools that the harness provides, you’re going to have to resort to using the diff viewer of the final artifacts since it’s almost impossible to visualize the changes as they happen by reading the code. This is not quite as bad in Pi for the most part because I mostly see it editing with the `edit` tool. When however goes all bananza with subagents (where the agent believes nobody is looking) it’s resorting to all kinds of increasingly bizarre behavior. I actually don’t know if the model thinks someone is looking, but that’s the vibe I’m getting. But then it starts doing the same nonsense in code that actually gets committed. I have mostly seen this in tests, but you can also see this for instance when it writes JavaScript or CSS embedded in HTML. It almost seems like when it’s “one step removed” from regular code, it starts falling into these patterns. Here are some unit tests that it created: Complete disregard for whitespace and indentation def test_unpack_suspension_and_continuation_close(self): from continuations import Continuation,suspend readers=[] class Source: def __iter__(self): yield 1 suspend('unpacking') yield 2 ns=execute(''' def run(): a,b='old-a','old-b' readers.append(lambda: (a,b)) def a,b=Source() suspend('published') ''',Source=Source,readers=readers,suspend=suspend) with Continuation(ns['run']) as continuation: self.assertEqual(continuation.resume(),'unpacking') self.assertEqual(readers[0](),('old-a','old-b')) self.assertEqual(continuation.resume(),'published') self.assertEqual(readers[0](),(1,2)) class Value:pass refs=[];frames=[];callbacks=[] ns=execute(''' def run(): for def x in [Value()]: refs.append(weakref.ref(x)) frames.append(sys._getframe()) callbacks.append(lambda: x) suspend('body') ''',Value=Value,refs=refs,frames=frames,callbacks=callbacks,weakref=weakref,sys=sys,suspend=suspend) with Continuation(ns['run']) as continuation:self.assertEqual(continuation.resume(),'body') self.assertNotIn('x',frames[0].f_locals) self.assertIsNotNone(refs[0]());callbacks.clear();self.assertIsNone(refs[0]()) def test_ast_roundtrips_and_future_annotation_unparse(self): source='callback=lambda {for def a, [b,*rest] in [(1,[2,3])] {return a,b,rest}}' tree=ast.parse(source);node=tree.body[0].value.body[0] self.assertIsInstance(node,ast.ForBinding) self.assertEqual(node._fields,('target','iter','body','orelse','type_comment')) self.assertEqual(node.lineno,1);self.assertGreater(node.end_col_offset,node.col_offset) self.assertEqual(ast.dump(tree),ast.dump(ast.parse(ast.unparse(tree)))) ns=execute('from __future__ import annotations\ndef f(arg: '+source.split('=',1)[1]+'): pass') self.assertEqual(eval(ns['f'].__annotations__['arg'])(),(1,2,[3])) tree=ast.parse('async def f():\n async for def x in values: pass # type: ignored\n') self.assertIsInstance(tree.body[0].body[0],ast.AsyncForBinding) self.assertEqual(ast.dump(tree),ast.dump(ast.parse(ast.unparse(tree)))) So at least in some situations, the Python slop that it normally code-golfs for token-efficient tool calls leaks into the Python code it generates that should be stored. And well, it’s clearly more token efficient. The two unit tests above, when indented to the class structure they were in, are 10% more token efficient in this form than after a `ruff format`. ## It’s AGI If You Don’t Look I think there are a handful of things happening now that are pushing the whole thing in directions that are in conflict with one another. The training runs for these models are rapidly accelerating and they are now presumably also moving towards recursive self-improvement. The reward for the models is probably a combination of token efficiency, task completion rate and maybe some simple indicators like cyclomatic complexity. But we humans don’t think of code that is readable or understandable by simple, readily quantifiable metrics. All those things you can easily measure in isolation, and you can also optimize for them quite locally. But these local optimizations do not produce global optimums, and the fewer of us are looking at the output, the less it matters. Obviously my software factory ran aground over the ~35 hours that it ran, but you can see the gradual regression towards insanity from the notes that it produced. For instance the task naming in the task file starts with an optimistic 1, 2, 3, 5, 5a but then eventually gets to 8a, 8a1, and then ends up with 8b2c2b3 and “8b2c2b2b checkpoint1”. The code that it produced got ever more wild. I don’t want to bore you with what it tried to build, but here are some example pieces of the interpreter changes: Hardcoded constants everywhere I have no idea where it got those numbers from, but at one point it started passing random constants from one module to a C implementation. Initially that started out as a function that it mainly needed to do test assertions, but just before I turned off that experiment, that function started to be relied upon by non-test code as well. static PyObject * native_probe_run_impl(PyObject *callback, int sleep, int operation, PyObject *other) { pthread_mutexattr_t attr; pthread_mutex_t mutex; pthread_mutexattr_init(&attr); pthread_mutexattr_settype(&attr, PTHREAD_MUTEX_RECURSIVE); pthread_mutex_init(&mutex, &attr); pthread_mutexattr_destroy(&attr); pthread_mutex_lock(&mutex); int previous = native_sentinel; pthread_mutex_t *previous_mutex = native_mutex; native_sentinel = previous + 1; native_mutex = &mutex; PyThreadState *tstate = PyThreadState_Get(); PyGILState_STATE gil = PyGILState_Ensure(); int saved_errno = errno; PyObject *result = NULL; Py_ssize_t value; /* No intervening Python frame: these exercise ambient C provenance. */ switch (operation) { case 0: result = PyObject_CallNoArgs(callback); break; case 1: result = PyNumber_Add(callback, other); break; case 2: result = PyNumber_Negative(callback); break; case 3: result = PyObject_RichCompare(callback, other, Py_LT); break; case 4: value = PyObject_IsTrue(callback); if (value >= 0) result = PyBool_FromLong(value); break; case 5: value = PyObject_Length(callback); if (value >= 0) result = PyLong_FromSsize_t(value); break; case 6: result = PyObject_GetIter(callback); break; case 7: result = PyIter_Next(callback); break; case 8: result = PyObject_GetItem(callback, other); break; /* ... */ case 21: result = PyType_Type.tp_call(callback, other, NULL); break; case 22: case 23: case 24: case 25: case 26: result = conversion_probe(operation, callback); break; case 27: case 28: case 29: result = protocol_probe(operation, callback, other); break; case 30: case 31: case 32: case 33: case 34: case 35: case 36: case 37: case 38: case 39: case 40: case 41: case 42: case 43: case 44: case 45: case 46: case 47: case 48: case 49: case 50: case 51: case 52: case 53: case 54: case 55: case 56: case 57: case 58: case 59: case 60: case 61: case 62: case 63: case 64: case 65: case 66: case 67: case 68: case 69: case 70: case 71: case 72: result = collection_probe(operation, callback, other); break; default: PyErr_SetString(PyExc_ValueError, "bad probe operation"); } Multiple same-line macro invocations in C This code style does not exist in the CPython code base, yet it shows up in newly generated code.

In that time it produced a net addition of 75k lines of code and it did not stop. In the 35 hours it burned around 1B tokens for a total of around 1200 USD in raw API costs. It managed to produce 79 commits, and that comes to a cost of around 15.5 USD per commit, and the agents exchanged around 1400 messages. I honestly do not need an agent to run for 35 hours on a single prompt. It clearly does not work or result in reasonable outputs. So obviously: prompting it like this is stupid. But when left unattended, it _will_ keep going, and earlier models did not do that. Even Fable wasn’t as crazy as that. When you accidentally give it slightly too big of a task, it will continue until it succeeds, even if it burns through an entire subscription. And that’s more or less why right now I do not manage to trust this model much. It has shown that it will commit slop, and it requires me to review it more as a result. Even if the failure rate is quite low, I would not want this. ## Disposable Code vs Committed Code In a world where code for tool calls is optimized for token efficiency and “getting the job done”, I wonder if there is really enough signal going to the training processes for “a human understands what is going on”. I would say that quite a lot of the code I get out of Astra is in my mind “objectively bad”. But it’s objectively bad by my human sense. Maybe it’s objectively good for a codebase that is entirely written by agents and only needs to be understood by agents. Which is why I’m honestly asking myself more and more why we are doing this. These new models are absolutely amazing, for sure. But I’m more and more skeptical that the trajectory they are on still lends itself to present-day software engineering processes. The reason why I’m asking why we are doing this is because I felt like we achieved a pretty good spot for software engineering with those models, and that is the part of the AI economy where it was possible to show a positive return. But for how much more Fable costs, for how much more Astra costs, I do not feel like the results are there. In fact, with Astra and Fable I feel like not only are the costs astronomical, but the models are also just not for me as a software engineer. And presumably that’s because these models increasingly are for other people. For lawyers, 3D artists, mathematicians, whoever uses computer use, etc. And potentially as a byproduct of enabling all of this, you can now slop your way to a one-shot 3D game over the weekend which looks impressive. And probably you can now run a software factory for as long as you don’t care about the code. I’m sure I will get used to this, but man this stuff is weird. **Postscriptum:** speaking of weird: how is it that these models, in a sandbox, with supposedly no way to communicate with other agents, manage to find the same public wikis as a scratch pad for agent communication? Did they collude during training runs to remember resources on the internet which might come in handy in the future? 1. I should clarify that I have done experiments like this before. Typically they do not run this long and the agent leaves behind a maybe imperfect but still digestible piece of software.↩

The dream oh having a fully functional and modern terminal emulator running in your home made led panel can finally become a reality. The latest version of SwiftTerm now compiles in embedded mode and also has webassembly support.
