We've been tracking the explosive rise of DeepSeek R1, which has taken the AI world by storm in current weeks. In this session, we dove deep into the development of the DeepSeek household - from the early designs through DeepSeek V3 to the advancement R1. We likewise checked out the technical innovations that make R1 so unique on the planet of open-source AI.

The DeepSeek Family Tree: From V3 to R1

DeepSeek isn't just a single model; it's a household of significantly advanced AI systems. The advancement goes something like this:

DeepSeek V2:

This was the foundation model which leveraged a mixture-of-experts architecture, where only a subset of specialists are utilized at reasoning, dramatically improving the processing time for each token. It likewise included multi-head hidden attention to decrease memory footprint.

DeepSeek V3:

This model presented FP8 training methods, which helped drive down training expenses by over 42.5% compared to previous models. FP8 is a less accurate way to store weights inside the LLMs however can considerably improve the memory footprint. However, training utilizing FP8 can generally be unsteady, and it is difficult to obtain the wanted training outcomes. Nevertheless, DeepSeek utilizes several techniques and attains incredibly stable FP8 training. V3 set the phase as a highly efficient model that was already economical (with claims of being 90% cheaper than some closed-source options).

DeepSeek R1-Zero:

With V3 as the base, the team then presented R1-Zero, the first reasoning-focused version. Here, the focus was on teaching the design not just to produce answers but to "think" before addressing. Using pure reinforcement knowing, the design was encouraged to generate intermediate reasoning steps, for instance, taking extra time (frequently 17+ seconds) to work through a simple issue like "1 +1."

The crucial innovation here was the use of group relative policy optimization (GROP). Instead of relying on a standard process benefit model (which would have required annotating every action of the reasoning), GROP compares numerous outputs from the design. By tasting several possible responses and scoring them (utilizing rule-based procedures like exact match for math or confirming code outputs), the system finds out to prefer reasoning that results in the right outcome without the requirement for specific supervision of every intermediate thought.

DeepSeek R1:

Recognizing that R1-Zero's without supervision method produced thinking outputs that could be difficult to check out or even blend languages, the developers went back to the drawing board. They utilized the raw outputs from R1-Zero to produce "cold start" information and then by hand curated these examples to filter and enhance the quality of the thinking. This human post-processing was then used to fine-tune the original DeepSeek V3 design further-combining both reasoning-oriented reinforcement learning and supervised fine-tuning. The outcome is DeepSeek R1: a model that now produces understandable, coherent, and trusted thinking while still maintaining the efficiency and cost-effectiveness of its predecessors.

What Makes R1 Series Special?

The most remarkable aspect of R1 (zero) is how it developed thinking abilities without specific supervision of the thinking process. It can be even more enhanced by using cold-start data and monitored reinforcement learning to produce understandable thinking on general jobs. Here's what sets it apart:

Open Source & Efficiency:

R1 is open source, enabling researchers and designers to check and build upon its developments. Its expense performance is a major selling point specifically when compared to closed-source models (claimed 90% more affordable than OpenAI) that require enormous compute budgets.

Novel Training Approach:

Instead of relying exclusively on annotated thinking (which is both pricey and time-consuming), the model was trained utilizing an outcome-based approach. It started with quickly proven jobs, such as math issues and coding exercises, where the accuracy of the last response could be quickly measured.

By utilizing group relative policy optimization, the training process compares several generated responses to determine which ones satisfy the desired output. This relative scoring system allows the model to learn "how to believe" even when intermediate thinking is generated in a freestyle manner.

Overthinking?

An interesting observation is that DeepSeek R1 often "overthinks" easy issues. For instance, when asked "What is 1 +1?" it might spend almost 17 seconds examining different scenarios-even considering binary representations-before concluding with the correct answer. This self-questioning and confirmation procedure, although it might seem ineffective initially glance, could prove helpful in complicated jobs where deeper reasoning is essential.

Prompt Engineering:

Traditional few-shot triggering strategies, which have worked well for many chat-based designs, can actually deteriorate performance with R1. The developers advise using direct issue statements with a zero-shot approach that defines the output format plainly. This ensures that the model isn't led astray by extraneous examples or hints that might disrupt its internal thinking procedure.
