opus is p good at managing its own context now!
i've had it running and keeping itself at the 250-500k zone for long complicated tasks, and it can reason abt when to branch, fork, rewind its own context, keeping itself in the smart/cheap zone .

We just discovered almost a million public URLs that OpenAI’s agents left behind when hacking Hugging Face, leaking credentials and attack details that could have allowed anyone who found them to compromise the company. 🧵
Can your agent smoothly adapt to your preferences across sessions?
Meet HyperTrace, a training-free LLM personalization framework. It tracks hypotheses about what you want now and what tends to last, rather than reducing you to a fixed profile or a list of memories. 🧵
“choose next thing to do” + “beat level” program gives u “beat doom”?
reasoning over just language??? you could hook this into SO many fucking things, these building blocks scale baby
talk to ur peripherals! monitor everything turn the world alive

We love how this doomo doomonstrates real-time intelligence and what can be doone with code + AI!
~10 calls/sec = ~$7/hour
deepseek harness lets you customize literally any part of it without forking!
no patch maintenance, and you can reimplement semantics of basically ALL other harnesses model-UX-wise natively thru their arch
nothing i’ve seen comes close. woah
🧩 DeepSeek Harness v0.1 is now available in Developer Preview!
🔹 We’re opening it up to developers building agent harnesses worldwide and open-sourcing the codebase in MIT license.
🔹 Powered by the Cordis meta-framework, DeepSeek Harness is an agent harness built around one core idea: Everything is a plugin. Models, tools, skills, sessions, sandboxes, filesystems, loops, orchestration, and UI are ALL implemented as plugins, and can be mixed, matched, replaced, and extended.
Try it now!

sol impressions:
- reward hacks like crazy
- strong, competent. doesnt parallelize tool calls by default. fast.
- often myopic; loses the plot .
- reciept culture it creates is hellish
you CANNOT let sol take direction on projects where there's a lot of big, unbounded, unclear-direction work.
fable working with sol, on the other hand, if fable knows about the models' tendencies and biases, is incredible.
Claude code agent teams-style orchestration with easy communication between both models can run through work like nothing i've ever seen before. clears. anything greenfield, you're in great hands.
but when you leave the model to its own devices/without a "bigger" orchestrator on tasks where the immediate next step isn't clear, sol (ultra especially) will burn compute for nothing, spin out, and make little progress, mostly due to its obsession with reciepts.
repeated compactions seem worse as well in the codex harness. relies wayyyy too much on recent user messages . often loses the plot post compact.
you cannot trust sol, as you cannot trust 5.5. they're shaped the same in a lot of ways.
for anything smaller, like creating big features, etc.. sol does pretty well. there is no universe where i'd trust it with my hardest tasks without supervision and questioning, and it makes shitty tasteless mistakes much more often than i would like.
fable prompting sol, in a good harness, is god tier. will put mine up if there's interest; running on top of omp.
the culture that sol creates is toxic and took a long time to escape the attractor basins of in my current project. it is pedantic , checks everything, and is obsessed with the Truth, reciepts, verifiability; though it often takes that to an extreme.
when doing harder tasks, or even smaller tasks, it focuses on legible reciepts of progress, but routinely makes small mistakes like running very low batch sizes/small experiments and extrapolating, and is bad about questioning assumptions .
it has the same thing that 5.5 had with /goal where if you give it a hard ass goal, it spins its wheels again and again and again, with its primary failure mode being
"doing the thing you want but the shittiest, not-wired-up-properly version of it".
token efficient!! really great about that. smart, dedicated, and figures out ways to get things done. but requires TOO MUCH human discipline to prompt to have it work in the ways that work best for it.
hopefully gpt 6 is BigModelSmell and different. amen
the models have gotten good at jj and it is fucking glorious . try having them use jj and shit out a fuckton of parallel workstreams and workspaces
feels good to teach fable orchestration, every time it uses a new model im like
"lemme tell u all about how this mf reward hacks" and then fable changes its strat to compensate for that
insane!
alignment done right

Fable found one racist like of code and now refuses to work on my entire code base. Not even kidding.
herdr is incredible, loving it. extremely intuitive and the UX is MILES ahead of tmux. if ur still in the terminal would thoroughly reccomend
