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 development of the DeepSeek household - from the early models through DeepSeek V3 to the breakthrough R1. We likewise explored the technical innovations that make R1 so special in the world of open-source AI.

The DeepSeek Ancestral Tree: From V3 to R1

DeepSeek isn't simply a single model; it's a household of increasingly sophisticated AI systems. The evolution goes something like this:

DeepSeek V2:

This was the foundation model which leveraged a mixture-of-experts architecture, where only a subset of professionals are utilized at reasoning, significantly improving the processing time for each token. It also included multi-head latent attention to lower memory footprint.

DeepSeek V3:

This design presented FP8 training methods, which helped drive down training expenses by over 42.5% compared to previous iterations. FP8 is a less accurate way to keep weights inside the LLMs but can considerably enhance the memory footprint. However, training using FP8 can usually be unstable, and it is hard to obtain the desired training outcomes. Nevertheless, DeepSeek uses several tricks and attains extremely steady FP8 training. V3 set the phase as a highly effective model that was currently cost-efficient (with claims of being 90% less expensive than some closed-source options).

DeepSeek R1-Zero:

With V3 as the base, the team then presented R1-Zero, the very first reasoning-focused version. Here, the focus was on teaching the model not simply to create responses however to "think" before answering. Using pure support knowing, the design was encouraged to create intermediate thinking actions, for example, taking additional time (frequently 17+ seconds) to resolve an easy problem like "1 +1."

The essential development here was the usage of group relative policy optimization (GROP). Instead of relying on a conventional process benefit model (which would have needed annotating every action of the thinking), GROP compares numerous outputs from the design. By sampling several possible answers and scoring them (using rule-based measures like precise match for math or confirming code outputs), the system discovers to favor thinking that results in the proper outcome without the requirement for specific supervision of every intermediate idea.

DeepSeek R1:

Recognizing that R1-Zero's not being watched method produced reasoning outputs that could be hard to check out and even mix languages, the developers went back to the drawing board. They utilized the raw outputs from R1-Zero to produce "cold start" data and after that manually curated these examples to filter and improve the quality of the thinking. This human post-processing was then used to fine-tune the initial DeepSeek V3 design further-combining both reasoning-oriented support learning and supervised fine-tuning. The outcome is DeepSeek R1: a model 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 interesting aspect of R1 (absolutely no) is how it established reasoning abilities without specific guidance of the thinking process. It can be further enhanced by using cold-start information and supervised reinforcement finding out to produce legible thinking on basic tasks. Here's what sets it apart:

Open Source & Efficiency:

R1 is open source, enabling scientists and designers to examine and build on its developments. Its expense efficiency is a major selling point especially when compared to closed-source models (claimed 90% more affordable than OpenAI) that need huge compute budgets.

Novel Training Approach:

Instead of relying exclusively on annotated reasoning (which is both pricey and time-consuming), the design was trained using an outcome-based method. It began with easily proven tasks, such as math problems and coding exercises, where the of the last response could be easily measured.

By utilizing group relative policy optimization, the training process compares several produced answers to determine which ones meet the wanted output. This relative scoring mechanism allows the design to discover "how to think" even when intermediate thinking is produced in a freestyle way.

Overthinking?

An intriguing observation is that DeepSeek R1 sometimes "overthinks" simple issues. For example, when asked "What is 1 +1?" it may spend almost 17 seconds assessing different scenarios-even considering binary representations-before concluding with the correct answer. This self-questioning and verification procedure, although it might appear inefficient at very first glance, could prove helpful in intricate tasks where much deeper thinking is essential.

Prompt Engineering:

Traditional few-shot triggering strategies, which have worked well for many chat-based designs, can really degrade performance with R1. The designers recommend utilizing direct problem declarations with a zero-shot method that specifies the output format plainly. This ensures that the model isn't led astray by extraneous examples or hints that might interfere with its internal thinking process.
