We've been tracking the explosive rise of DeepSeek R1, which has taken the AI world by storm in recent weeks. In this session, we dove deep into the evolution of the DeepSeek family - from the early models 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 design; it's a household of significantly advanced AI systems. The advancement goes something like this:

DeepSeek V2:

This was the structure design which leveraged a mixture-of-experts architecture, where only a subset of professionals are utilized at inference, considerably enhancing the processing time for each token. It also featured multi-head hidden attention to lower memory footprint.

DeepSeek V3:

This design introduced FP8 training methods, which assisted drive down training costs by over 42.5% compared to previous iterations. FP8 is a less exact method to keep weights inside the LLMs but can considerably improve the memory footprint. However, training using FP8 can generally be unstable, and it is difficult to obtain the wanted training results. Nevertheless, DeepSeek utilizes numerous techniques and attains remarkably steady FP8 training. V3 set the phase as an extremely effective model that was already economical (with claims of being 90% more affordable than some closed-source options).

DeepSeek R1-Zero:

With V3 as the base, the team then introduced R1-Zero, the very first reasoning-focused iteration. Here, the focus was on teaching the model not just to create responses however to "think" before addressing. Using pure support knowing, the design was motivated to generate intermediate reasoning steps, for example, taking extra time (frequently 17+ seconds) to overcome an easy issue like "1 +1."

The key development here was using group relative policy optimization (GROP). Instead of relying on a traditional procedure benefit model (which would have required annotating every step of the thinking), GROP compares several outputs from the design. By tasting a number of possible responses and scoring them (utilizing rule-based steps like specific match for mathematics or validating code outputs), the system discovers to prefer thinking that results in the appropriate outcome without the need for specific supervision of every intermediate idea.

DeepSeek R1:

Recognizing that R1-Zero's unsupervised method produced thinking outputs that could be hard to check out and even mix languages, the designers went back to the drawing board. They used the raw outputs from R1-Zero to produce "cold start" information and after that manually curated these examples to filter and improve the quality of the thinking. This human post-processing was then used to tweak the initial DeepSeek V3 design further-combining both reasoning-oriented reinforcement learning and supervised fine-tuning. The outcome is DeepSeek R1: a design that now produces legible, coherent, and reliable thinking while still maintaining the performance and cost-effectiveness of its predecessors.

What Makes R1 Series Special?

The most remarkable element of R1 (no) is how it developed reasoning capabilities without specific guidance of the reasoning procedure. It can be even more improved by utilizing cold-start information and monitored support finding out to produce readable reasoning on basic tasks. Here's what sets it apart:

Open Source & Efficiency:

R1 is open source, allowing scientists and designers to inspect and build on its developments. Its cost efficiency is a major selling point particularly when compared to closed-source designs (claimed 90% cheaper than OpenAI) that need huge compute spending plans.

Novel Training Approach:

Instead of relying entirely on annotated thinking (which is both costly and time-consuming), the model was trained using an outcome-based technique. It started with easily verifiable jobs, such as math issues and coding workouts, where the accuracy of the last response might be quickly measured.

By utilizing group relative policy optimization, the training process compares numerous produced responses to figure out which ones meet the desired output. This relative scoring system enables the model to learn "how to think" even when intermediate thinking is in a freestyle way.

Overthinking?

A fascinating observation is that DeepSeek R1 often "overthinks" simple problems. For example, when asked "What is 1 +1?" it may invest almost 17 seconds evaluating various scenarios-even thinking about binary representations-before concluding with the appropriate response. This self-questioning and confirmation process, although it might appear inefficient in the beginning look, might show helpful in complicated jobs where much deeper thinking is essential.

Prompt Engineering:

Traditional few-shot triggering methods, which have actually worked well for numerous chat-based models, can in fact degrade efficiency with R1. The designers recommend using direct problem statements with a zero-shot method that specifies the output format plainly. This ensures that the design isn't led astray by extraneous examples or hints that might interfere with its internal reasoning process.
