OpOp — The Optimizer Optimizer
Because your optimizer is dumb and somebody had to say it 
pip install opop
from opop import OptBrain
optimizer = OptBrain(torch.optim.Adam(model.parameters(), lr=1e-3))
# literally just add loss= and ur done lol
optimizer.step(loss=loss.item())
thats it. thats the whole thing. ur welcome 
wtf is this
Adam stores two full copies of every parameter in your model.
Two. Full. Copies. 
Your model has 500M parameters? Cool, Adam is sitting on 4 GIGABYTES
of optimizer state running the same formula over and over like a goldfish
that forgot it already swam that lap.
It doesnt know what step youre on. It doesnt know the loss plateaued 200 steps ago.
It doesnt know that parameter group 3 is oscillating like crazy while group 1 converged
an hour ago. It doesnt know ANYTHING. Its just vibing with exponential moving averages.
Forever. Until you stop it. 
OpOp is a tiny brain that watches your training and learns what helps.
loss going down? brain remembers what it did
loss going up? brain remembers that too and stops doing it
gradients oscillating? brain dampens that group
parameters stuck? brain pushes harder
early training chaos? brain stays cautious
converging nicely? brain gets out of the way
50KB. not 4GB. 50KB. a brain that THINKS vs a buffer that DOESNT. 
how it works (for babies)
- your optimizer does its normal thing (Adam, SGD, whatever grandpa uses)
- OpOp watches what happened
- tiny brain goes “hmm”
- outputs 3 knobs per parameter group:
- scale — push harder or softer (0.01x to 10x)
- clip — tighter or looser leash (0.1x to 5x)
- dampen — chill out or full send (0 to 1)
- loss went down? brain learns “that was good”
- loss went up? brain learns “dont do that again”
- repeat forever, brain gets smarter, training gets better
its literally reinforcement learning on your optimizer.
the optimizer is optimizing the optimizer. OpOp. ²
features
- drop-in — wraps any pytorch optimizer. 3 lines. done.
- learns online — no pre-training needed. starts neutral, gets smarter.
- cant make things worse — initialized at 1x everything. worst case = base optimizer unchanged.
- ~50KB memory — less than your models bias terms lmao
- ~0.1% compute — a tiny MLP forward pass per step. your GPU wont even notice.
- saves/loads — brain checkpoints alongside your model. it remembers across restarts.
- numpy mode — dont use pytorch? cool neither do we. works with anything.
- replaces — manual LR scheduling, gradient clip tuning, warmup schedules, differential learning rates, and all the other stuff you spend 3 hours tuning and still get wrong
what OpOp replaces
| thing you used to do manually | OpOp |
|---|---|
| cosine LR schedule | brain learns when to push/pull |
| warmup for 2000 steps | brain figures out early training is fragile |
| gradient clipping at 1.0 | brain adjusts clip per group dynamically  |
| different LR per param group | brain scales each group independently  |
| “try lr=3e-4 no wait 1e-4 no wait” | brain handles it  |
| staring at loss curves for hours | brain stares at them FOR you  |
numpy mode (for the unhinged)
from opop import OptBrain
brain = OptBrain(None, n_groups=5)
for batch in data:
loss = forward(batch)
decisions = brain.get_decisions(loss=loss)
for group_idx, (scale, clip, dampen) in decisions.items():
# apply to your weird custom optimizer
grads[group_idx] *= scale
# etc
brain.record_grads(group_idx, grad_flat)
brain.finish_step()
works with any optimizer in any framework in any language that can call python.
or just read the 50 lines of brain code and rewrite it in rust or whatever idc 
save ur brain
optimizer.save("big_brain.npz") # 🧠💾
optimizer.load("big_brain.npz") # 🧠⬆️
the brain remembers everything across restarts. loss history. gradient patterns.
what worked. what didnt. its not starting from scratch every time like
Adam does because Adam has amnesia and nobody talks about it. 
FAQ
Q: does this actually work?
A: the brain literally cannot make things worse. it starts at 1x (neutral) and only
changes if it learns something helpful. worst case you get base Adam. best case
you get Adam with a copilot.
Q: why hasnt anyone done this before?
A: because they think of optimizers as math, not as agents. Adam is an equation.
OpOp is a tiny creature that lives in your training loop and learns from experience.
the entire field put optimizers in the “math” box instead of the “agent” box and
never looked back. we looked back.
Q: how much overhead?
A: ~50KB memory. one tiny MLP forward pass per training step. your batch norm
layers use more compute than this.
Q: what if I have 47 parameter groups?
A: brain scales. observation vector grows by 6 floats per group. still tiny.
still fast. still smarter than Adam.
Q: can I use this with [obscure optimizer]?
A: if it has a .step() method, yes. if it doesnt, use numpy mode.
I made it for a ML architecture I designed myself because transformers are trash.
OpOp doesnt care whats underneath. it just watches and learns.
Q: is this a joke?
A: Adam is using 4GB to run a formula a calculator could do.
we’re using 50KB to run a brain. you tell me whos joking. 
built by
a guy who cant code and an AI on a metal shelf in Nebraska.
no degree. no funding. no pytorch copy-paste.
just “what if the optimizer could think” and then making it think.
if your PhD advisor told you optimizers cant have intent,
theyre wrong and you should send them this repo.
license
MIT. take it. use it. wrap your precious AdamW in a brain.
tell your coworkers “my optimizer has a brain now” and watch their face.
if you work at a big lab and this ends up in your training pipeline,
you owe us a hotdog. 
Adam stores 2 copies of your entire model to run a formula.
OpOp stores 50KB to make decisions.
one of these is obviously smarter than the other.

the optimizer optimizer has entered the chat.
“I’m not just optimizing models. I’m optimizing the thing that optimizes the models.”
— OpOp, probably
Here ya go nerds. An optimizer with actual intent about what its doing? Save the applause, your embarrassment is enough. Big brain time. Slap it on AdamW or something, would not surprise me.
Two gifts in one. Its you’re lucky day. This stuff is child’s play.
