We've been tracking the explosive increase of DeepSeek R1, which has actually taken the AI world by storm in recent weeks. In this session, we dove deep into the evolution of the DeepSeek household - from the early models through DeepSeek V3 to the breakthrough R1. We also explored the technical innovations that make R1 so unique in the world 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 experts are utilized at inference, significantly enhancing the processing time for each token. It also featured multi-head hidden attention to lower memory footprint.
DeepSeek V3:
This model presented FP8 training strategies, which assisted drive down training costs by over 42.5% compared to previous versions. FP8 is a less accurate way to keep weights inside the LLMs but can significantly enhance the memory footprint. However, training utilizing FP8 can normally be unstable, and it is hard to obtain the wanted training results. Nevertheless, DeepSeek utilizes multiple tricks and attains extremely stable FP8 training. V3 set the phase as an extremely effective design that was currently affordable (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 iteration. Here, the focus was on teaching the model not simply to produce responses but to "believe" before responding to. Using pure reinforcement learning, the model was motivated to produce intermediate thinking steps, for instance, taking extra time (frequently 17+ seconds) to overcome a simple issue like "1 +1."
The essential development here was the use of group relative policy optimization (GROP). Instead of counting on a traditional procedure benefit design (which would have needed annotating every action of the thinking), GROP compares multiple outputs from the design. By sampling several potential responses and scoring them (utilizing rule-based measures like exact match for math or validating code outputs), the system finds out to favor reasoning that results in the appropriate result without the need for specific guidance of every intermediate idea.
DeepSeek R1:
Recognizing that R1-Zero's without supervision method produced thinking outputs that might be hard to check out and even mix languages, the developers returned to the drawing board. They utilized the raw outputs from R1-Zero to generate "cold start" data and after that by hand curated these examples to filter and improve the quality of the thinking. This human post-processing was then utilized to fine-tune the initial DeepSeek V3 design further-combining both reasoning-oriented support learning and supervised fine-tuning. The result is DeepSeek R1: a model that now produces legible, meaningful, and trusted reasoning while still maintaining the performance and cost-effectiveness of its predecessors.
What Makes R1 Series Special?
The most remarkable aspect of R1 (absolutely no) is how it developed thinking capabilities without specific guidance of the thinking procedure. It can be even more improved by utilizing cold-start information and supervised support learning to produce readable thinking on basic tasks. Here's what sets it apart:
Open Source & Efficiency:
R1 is open source, enabling researchers and developers to inspect and build on its developments. Its cost performance is a significant selling point specifically when compared to closed-source models (claimed 90% cheaper than OpenAI) that need huge calculate budget plans.
Novel Training Approach:
Instead of relying exclusively on annotated reasoning (which is both pricey and lengthy), the design was trained utilizing an outcome-based method. It started with easily proven jobs, such as math issues and coding workouts, where the accuracy of the last response could be quickly measured.
By utilizing group relative policy optimization, the training procedure compares several created responses to determine which ones meet the desired output. This relative scoring system allows the design to find out "how to believe" even when intermediate reasoning is created in a freestyle manner.
Overthinking?
An interesting observation is that DeepSeek R1 often "overthinks" simple issues. For example, when asked "What is 1 +1?" it might invest nearly 17 seconds examining various scenarios-even thinking about binary representations-before concluding with the proper response. This self-questioning and confirmation process, although it might appear inefficient in the beginning glimpse, might prove useful in intricate tasks where deeper thinking is essential.
Prompt Engineering:
Traditional few-shot prompting strategies, which have actually worked well for lots of chat-based models, can really degrade performance with R1. The developers suggest using direct issue 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 tips that might interfere with its internal thinking process.
Getting Going with R1

Smaller versions (7B-8B) can operate on consumer GPUs and even only CPUs
Larger variations (600B) need significant compute resources
