Bittensor subnet 125 · Incentivized LLM research

Accelerating Open Intelligence
through incentivized research.

Refinery accelerates open-source AI through a decentralized search for better training algorithms. We begin with the optimizer: the rule that turns gradients into learning.

The opportunity

Performance starts with
algorithms and data.

AdamW and Muon are milestones, not the endpoint. A wider search, accurate evaluation, and rewards for real improvements could move optimizer development substantially further.

Model capability has advanced dramatically. We believe there is still substantial headroom in the lower-level operations used to produce it. A better update rule can improve what a training run achieves with the compute it already has.

The optimizer is part of what makes that capability attainable. From stochastic gradient descent and momentum to adaptive methods such as Adam and AdamW, improvements to the update rule have helped shape modern training. In language-model experiments, optimizer choice can substantially change the loss reached within a fixed training budget—not just how quickly the same result arrives.

Useful algorithmic advances can come from academic research, open-source experiments, and independent contributors as well as frontier labs. Refinery makes this work an ongoing, incentivized search: miners propose improvements, a common evaluation measures them, and verified progress earns rewards.

The aim is Open Intelligence: advances that compound across the training process and give open-source AI a stronger foundation. Better algorithms should become building blocks for everyone.

Why we think there is room to improve ↗
The vision

Change the trajectory
of open models.

The remaining gap with closed systems is not only data. It is also the algorithms that decide how much a given budget of compute and data can produce.

Refinery exists to move the trajectory of open-source language models. Capability has advanced quickly, but we do not think the distance that remains is explained by data alone. The algorithms—the optimizers, kernels, and training methods—still have substantial headroom, including in ideas the field has treated as settled for years.

Some of that headroom is already public. Looped transformers are a small, open example of an older idea still being pushed. FlashAttention and Muon are larger ones: methods that produced large gains in speed or training efficacy once they reached the open community. We believe there are more improvements of that kind, and that a wider, incentivized search can find them.

We start with the optimizer. From launch, for at least six weeks, miners are rewarded for update rules that beat AdamW and Muon on small models under a fixed budget. That is the first target, not the last.

Further on, we want compute spent where there is signal: tokens that can be predicted, but only with intelligence—not those that are nearly random, and not those that are trivial. We are developing a compressor and a token-importance method for training data with that aim. Once the approach is solid, miners will be asked to iterate on it. The working title of that research is Meaning Before Manner.

Papers, reproducible evaluations, and academic collaborations—including emerging work with MIT labs through Kusanagi—are how we intend to bring the wider machine-learning community to Bittensor, and Bittensor’s results to them.

We think this is a consequential moment. Whether comparable capability exists in the open will shape who can use it. Our aim is to use Bittensor to point a global pool of miners at discoveries the open research community has not had in years, and to put those discoveries in everyone’s hands.

Why this matters for Bittensor

Open research.
A stronger Bittensor.

Refinery’s ambition extends beyond a better optimizer: advance open-source AI, demonstrate what Bittensor’s global talent pool can produce, and bring more researchers into the network.

01Open Intelligence

Advance research everyone can use.

Better training algorithms should empower the open-source world. By sharing methods, code and evaluation results, we aim to give researchers and builders stronger foundations for the next generation of open AI.

02Academic credibility

Put Bittensor on the academic map.

Use the network’s global talent pool to produce research that earns attention beyond Bittensor. Reproducible results, papers and open scrutiny can demonstrate what incentivized collaboration contributes to the field.

03Research talent

Bring researchers into Bittensor.

Make those results an invitation. Give talented researchers a concrete route into mining: contribute an optimizer, test it against a shared benchmark, and earn rewards for confirmed progress while advancing open research.

The aim is a reinforcing cycle: Bittensor enables useful research; that work builds academic credibility; and more researchers join as miners to push the work further.

Why start with gradient descent?

A focused question.
A tractable experiment.

Our view is that optimizer ideas are more practical to compare in smaller training runs than changes to the model architecture itself or the kernels that execute it. Keeping the model and data fixed lets us ask a precise question: does this update rule train better within the same budget?

Search

Explore beyond the defaults.

Miners can refine established methods or propose a different update rule. Human insight, automated experiments, and LLM research agents can all contribute to the search.

Measure

Make improvement count.

Each submission faces the same model, data, and compute budget. Better val loss is the result that matters. An apparent win must hold up in a confirmation run.

Reward

Pay for progress.

Confirmed improvements earn emission in proportion to their size and recency. Published code and evaluation records give future contributors a stronger starting point.

The experiment is the point

Can better incentives
produce better optimizers?

Two beliefs sit behind the subnet: that affordable experiments can identify improvements worth evaluating in larger runs, and that Bittensor’s miners can discover them. Early work with research agents gave us enough encouragement to open the search to the network.

The longer view

Compounded advances across
the set of algorithms
behind a training run.

Descent algorithms are our starting point. Pretraining data quality and reinforcement-learning environments are other components where a wider pool of contributors could make useful advances.

When we compare models from OpenAI with open-weight families such as Qwen and Kimi, we see the outcome of many interacting choices across training. Refinery’s ambition is to help close capability and efficiency gaps by improving those ingredients, one measurable target at a time.
