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 advancement of the DeepSeek household - from the early models through DeepSeek V3 to the development R1. We also explored the technical innovations that make R1 so special 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 sophisticated AI systems. The development goes something like this:

DeepSeek V2:

This was the foundation model which leveraged a mixture-of-experts architecture, where just a subset of experts are used at inference, drastically improving the processing time for each token. It also included multi-head latent attention to decrease memory footprint.

DeepSeek V3:

This design presented FP8 training methods, which assisted drive down training expenses by over 42.5% compared to previous iterations. FP8 is a less precise way to save weights inside the LLMs but can considerably improve the memory footprint. However, training using FP8 can usually be unstable, and it is difficult to obtain the preferred training results. Nevertheless, DeepSeek uses several techniques and attains incredibly steady FP8 training. V3 set the stage as an extremely efficient model that was currently affordable (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 first reasoning-focused iteration. Here, the focus was on teaching the model not simply to generate answers but to "believe" before addressing. Using pure support learning, the design was motivated to generate intermediate thinking steps, for instance, taking extra time (frequently 17+ seconds) to overcome a basic issue like "1 +1."

The key development here was the use of group relative policy optimization (GROP). Instead of counting on a conventional procedure reward design (which would have required annotating every step of the reasoning), GROP compares several outputs from the design. By sampling numerous potential answers and scoring them (utilizing rule-based procedures like specific match for math or verifying code outputs), the system discovers to favor thinking that leads to the appropriate outcome without the need for specific supervision of every intermediate idea.

DeepSeek R1:

Recognizing that R1-Zero's not being watched approach produced reasoning outputs that could be hard to read and even mix languages, the designers returned to the drawing board. They utilized the raw outputs from R1-Zero to produce "cold start" data and then manually curated these examples to filter and improve the quality of the thinking. This human post-processing was then used to tweak the original DeepSeek V3 design further-combining both reasoning-oriented reinforcement learning and monitored fine-tuning. The outcome is DeepSeek R1: a design that now produces understandable, meaningful, 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 (zero) is how it established thinking abilities without explicit guidance of the thinking procedure. It can be further improved by information and supervised support discovering to produce understandable reasoning on basic tasks. Here's what sets it apart:

Open Source & Efficiency:

R1 is open source, enabling scientists and developers to check and build on its innovations. Its cost performance is a significant selling point especially when compared to closed-source designs (claimed 90% less expensive than OpenAI) that need huge calculate budget plans.

Novel Training Approach:

Instead of relying solely on annotated reasoning (which is both pricey and time-consuming), the model was trained using an outcome-based technique. It started with quickly proven jobs, such as mathematics problems and coding workouts, where the correctness of the final answer could be quickly determined.

By using group relative policy optimization, the training procedure compares several produced answers to figure out which ones meet the wanted output. This relative scoring system enables the design to find out "how to think" even when intermediate thinking is created in a freestyle manner.

Overthinking?

An interesting observation is that DeepSeek R1 in some cases "overthinks" easy issues. For instance, when asked "What is 1 +1?" it may spend nearly 17 seconds assessing different scenarios-even considering binary representations-before concluding with the appropriate answer. This self-questioning and verification process, although it may seem ineffective initially glance, could show advantageous in complicated jobs where much deeper thinking is necessary.

Prompt Engineering:

Traditional few-shot prompting methods, which have actually worked well for many chat-based models, can in fact deteriorate performance with R1. The designers advise utilizing direct issue statements with a zero-shot technique that defines the output format plainly. This makes sure that the design isn't led astray by extraneous examples or yewiki.org tips that may interfere with its internal thinking procedure.
