Misinterpreting bitter lesson and an incredibly short period when scaling transformers did most of the legwork has reward hacked brains of a whole generation of scientists.

The more compute you’re pouring in training you’re model, the *more* important it is what algorithm you’re using.

There are algorithms that scale and algorithms that don’t and the only bitter lesson is that a lot of energy was spent on directions that were dead ends in the end. At the same time there are whole dimensions of scaling completely unexplored.

This is also going to get lot of young scientists upset because they stopped developing their insights thinking scaling transformers alone is sufficient and felt defeated due to “the bitter lesson”

Crazy what that crew is cookin
Joanne Jang Verified account @joannejang 1d
🚀 we're hiring MTS to cook with us on new kinds of agent runtime & systems.

what you'll build will both shape _and_ be shaped by new capabilities only possible with research.

some people you'll be working with are @_chenglou , @rtwlz , and @skcd42 as well as @MillionInt , @_arohan_ , and the rest of our absolutely insane team who will blow your mind every day.

if you think you might be a good fit, please do send me a message request with a short spiel on why!

Megakernels are the future and incredibly cracked teams seem to be pushing the boundaries of possibility each day getting further and further.

Looking forward to seeing more from this team 😀

We invented a recursive megakernel generator called Hyperkernel, the most complete solution to megakernels and GPU efficiency.

Hyperkernel-generated megakernels achieve state of the art performance on 11 different domains: inference (DeepSeek, Kimi and GLM), pretraining (Qwen), hardware fault recovery, robotics (π₀-FAST, ACT) diffusion and real time world models (Matrix-Game), full self driving (OpenPilot), voice models (Moshi), genomics (Evo 2) and protein folding (ESMFold).

All of this in a single kernel launch.

For context, Hyperkernel generated fully optimized megakernels for robotics, genomics and voice in under 50 minutes, and doubled the efficiency for >5 models generally using only about 60-100 lines of code per megakernel. This speaks to the unparalleled standard for code quality in the automated generations.

Our first release today open sources the megakernels themselves. Over the next couple weeks, we will release the entire Hyperkernel stack, along with the complete serving stack for Kimi and GLM (20-30% inference efficiency gains across all concurrencies).

Out of the box GPU machinery performs terribly for unorthodox research. We built Hyperkernel only 20 days ago for internal use; but given its multi-modality, we have decided to open source it.

Creative research should not be bottlenecked by the lack of dedicated infra teams. Hyperkernels offer a one stop shop infra stack for all research. We would love for the open source community to add to it :)

NOTE: We primarily use NVIDIA B300s, but our kernel generation extends to other hardware (B200s, AMD, TPUs).

1/9

We absolutely crush NVIDIA and achieve the best low latency inference for DeepSeek v4.1 Flash.

Compared with NVIDIA’s published vLLM results, Hyperkernel delivers:

• 36.7% higher per-user generation speed at concurrency 1.

• 28.2% higher per-user speed while serving two users, versus NVIDIA serving one.

• 15% higher per user speed while serving four users, versus NVIDIA serving one.

• 90.6% higher per-user generation speed at concurrency 4, compared with the highest published C4 AgentX interactivity for TP4 B300s.

• 28.5% higher per-user generation speed at concurrency 8, compared with NVIDIA's published result.

• 36% faster median per-request decode speed.
