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

The DeepSeek Family Tree: From V3 to R1

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

DeepSeek V2:

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

DeepSeek V3:

This design presented FP8 training methods, which helped drive down training costs by over 42.5% compared to previous iterations. FP8 is a less accurate method to save weights inside the LLMs but can considerably improve the memory footprint. However, training using FP8 can typically be unsteady, and it is difficult to obtain the wanted training outcomes. Nevertheless, DeepSeek uses numerous tricks and attains incredibly steady FP8 training. V3 set the stage as a highly effective design that was currently economical (with claims of being 90% cheaper 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 design not just to produce answers however to "believe" before addressing. Using pure support learning, the design was encouraged to produce intermediate reasoning actions, for instance, taking additional time (often 17+ seconds) to resolve an easy issue like "1 +1."

The key innovation here was the usage of group relative policy optimization (GROP). Instead of depending on a standard process reward design (which would have required annotating every action of the thinking), GROP compares several outputs from the design. By tasting numerous prospective answers and scoring them (using rule-based measures like exact match for math or verifying code outputs), the system learns to favor reasoning that leads to the correct result without the requirement for specific supervision of every intermediate thought.

DeepSeek R1:

Recognizing that R1-Zero's without supervision technique produced thinking outputs that might be difficult to read or even blend languages, the designers went back to the drawing board. They used the raw outputs from R1-Zero to create "cold start" information and then 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 reinforcement learning and monitored fine-tuning. The outcome is DeepSeek R1: a model that now produces understandable, coherent, and reputable thinking while still maintaining the efficiency and cost-effectiveness of its predecessors.

What Makes R1 Series Special?

The most interesting element of R1 (zero) is how it established reasoning abilities without specific supervision of the thinking process. It can be further improved by using cold-start information and monitored support discovering to produce readable thinking on general jobs. Here's what sets it apart:

Open Source & Efficiency:

R1 is open source, permitting researchers and designers to inspect and build on its innovations. Its cost efficiency is a major selling point particularly when compared to closed-source designs (claimed 90% more affordable than OpenAI) that require massive 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 method. It began with easily proven jobs, such as mathematics problems and coding workouts, where the correctness of the last response might be quickly measured.

By using group relative policy optimization, the training process compares multiple created responses to figure out which ones meet the desired output. This relative scoring mechanism enables 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 often "overthinks" easy issues. For example, when asked "What is 1 +1?" it may spend nearly 17 seconds examining various scenarios-even considering binary representations-before concluding with the proper answer. This self-questioning and verification procedure, although it may appear inefficient in the beginning look, could prove helpful in complicated jobs where much deeper thinking is essential.

Prompt Engineering:

Traditional few-shot triggering techniques, which have worked well for many chat-based models, can in fact deteriorate performance with R1. The developers recommend using direct issue declarations with a zero-shot approach that defines the output format plainly. This guarantees that the model isn't led astray by extraneous examples or tips that might disrupt its internal reasoning process.
