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 developments that make R1 so special worldwide of open-source AI.

The DeepSeek Ancestral Tree: From V3 to R1

DeepSeek isn't simply a single model; it's a family of increasingly advanced AI systems. The development goes something like this:

DeepSeek V2:

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

DeepSeek V3:

This model introduced FP8 training strategies, which assisted drive down training expenses by over 42.5% compared to previous models. FP8 is a less accurate way to save weights inside the LLMs but can significantly enhance the memory footprint. However, training using FP8 can normally be unsteady, and it is difficult to obtain the wanted training outcomes. Nevertheless, DeepSeek utilizes multiple techniques and attains extremely stable FP8 training. V3 set the phase as an extremely effective design that was already affordable (with claims of being 90% cheaper than some closed-source alternatives).

DeepSeek R1-Zero:

With V3 as the base, the team then presented R1-Zero, the first reasoning-focused model. Here, the focus was on teaching the model not simply to produce responses however to "think" before responding to. Using pure support learning, the design was motivated to generate intermediate reasoning actions, for instance, taking additional time (often 17+ seconds) to overcome a basic issue like "1 +1."

The key development here was using group relative policy optimization (GROP). Instead of relying on a standard procedure reward design (which would have needed annotating every action of the reasoning), GROP compares multiple outputs from the model. By sampling numerous potential answers and scoring them (utilizing rule-based procedures like precise match for mathematics or verifying code outputs), the system finds out to prefer reasoning that causes the proper outcome without the requirement for specific supervision of every intermediate thought.

DeepSeek R1:

Recognizing that R1-Zero's unsupervised approach produced reasoning outputs that might be hard to check out and even blend languages, the designers returned to the drawing board. They utilized the raw outputs from R1-Zero to generate "cold start" information and after that manually curated these examples to filter and enhance the quality of the thinking. This human post-processing was then utilized to tweak the original DeepSeek V3 design further-combining both reasoning-oriented support learning and monitored fine-tuning. The outcome is DeepSeek R1: a design that now produces understandable, coherent, and trusted thinking while still maintaining the effectiveness and cost-effectiveness of its predecessors.

What Makes R1 Series Special?

The most interesting aspect of R1 (zero) is how it established reasoning capabilities without specific supervision of the thinking process. It can be further enhanced by utilizing cold-start data and monitored support discovering to produce understandable reasoning on general jobs. Here's what sets it apart:

Open Source & Efficiency:

R1 is open source, allowing researchers and designers to check and build upon its innovations. Its cost effectiveness is a significant selling point especially when compared to closed-source designs (claimed 90% cheaper than OpenAI) that need enormous compute budgets.

Novel Training Approach:

Instead of relying entirely on annotated thinking (which is both expensive and lengthy), the design was trained utilizing an outcome-based technique. It began with quickly proven jobs, such as math problems and coding workouts, where the accuracy of the last answer might be quickly determined.

By utilizing group relative policy optimization, the training procedure compares multiple produced responses to determine which ones fulfill the desired output. This relative scoring system allows the model to learn "how to think" even when intermediate thinking is generated in a freestyle way.

Overthinking?

A fascinating observation is that DeepSeek R1 often "overthinks" basic problems. For instance, when asked "What is 1 +1?" it may invest almost 17 seconds assessing various scenarios-even considering binary representations-before concluding with the right response. This self-questioning and verification process, although it may seem ineffective initially glimpse, could show useful in intricate tasks where deeper reasoning is required.

Prompt Engineering:

Traditional few-shot triggering methods, which have worked well for numerous chat-based designs, can actually degrade performance with R1. The developers advise utilizing direct problem statements with a zero-shot technique that defines the output format plainly. This guarantees that the model isn't led astray by extraneous examples or hints that may hinder its internal reasoning procedure.
