We have actually 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 evolution of the DeepSeek family - from the early designs through DeepSeek V3 to the breakthrough R1. We also explored the technical developments that make R1 so special in the world of open-source AI.

The DeepSeek Family Tree: From V3 to R1

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

DeepSeek V2:

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

DeepSeek V3:

This model presented FP8 training techniques, which assisted drive down training costs by over 42.5% compared to previous models. FP8 is a less exact method to keep weights inside the LLMs however can greatly improve the memory footprint. However, training utilizing FP8 can generally be unsteady, and it is difficult to obtain the preferred training outcomes. Nevertheless, DeepSeek utilizes numerous techniques and attains remarkably steady FP8 training. V3 set the stage as an extremely efficient design that was currently economical (with claims of being 90% cheaper than some closed-source alternatives).

DeepSeek R1-Zero:

With V3 as the base, the group then introduced R1-Zero, the very first reasoning-focused model. Here, the focus was on teaching the design not just to generate responses however to "believe" before answering. Using pure reinforcement learning, the model was motivated to produce intermediate reasoning actions, for example, taking additional time (frequently 17+ seconds) to work through an easy problem like "1 +1."

The key innovation here was the use of group relative policy optimization (GROP). Instead of depending on a standard process reward model (which would have needed annotating every action of the thinking), GROP compares several outputs from the model. By sampling a number of possible responses and scoring them (using rule-based procedures like exact match for mathematics or confirming code outputs), the system discovers to prefer thinking that leads to the appropriate result without the requirement for explicit guidance of every intermediate thought.

DeepSeek R1:

Recognizing that R1-Zero's not being watched technique produced reasoning outputs that could be hard to read and even blend languages, the designers went back to the drawing board. They utilized the raw outputs from R1-Zero to generate "cold start" data and then by hand curated these examples to filter and enhance the quality of the reasoning. This human post-processing was then utilized to tweak the original DeepSeek V3 model further-combining both reasoning-oriented reinforcement knowing and monitored fine-tuning. The outcome is DeepSeek R1: a model that now produces readable, coherent, and trusted thinking while still maintaining the efficiency and cost-effectiveness of its predecessors.

What Makes R1 Series Special?

The most remarkable aspect of R1 (zero) is how it developed thinking capabilities without explicit guidance of the thinking procedure. It can be even more enhanced by using cold-start information and supervised reinforcement discovering to produce readable reasoning on general tasks. Here's what sets it apart:

Open Source & Efficiency:

R1 is open source, allowing researchers and designers to examine and develop upon its developments. Its expense effectiveness is a major selling point specifically when compared to closed-source models (claimed 90% more affordable than OpenAI) that require enormous compute spending 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 verifiable jobs, such as math issues and coding exercises, where the accuracy of the last answer could be quickly measured.

By utilizing group relative policy optimization, the training procedure compares several generated responses to figure out which ones satisfy the desired output. This relative scoring system permits the model to learn "how to think" even when intermediate reasoning is generated in a freestyle way.

Overthinking?

An intriguing observation is that DeepSeek R1 sometimes "overthinks" simple problems. For instance, when asked "What is 1 +1?" it might spend nearly 17 seconds evaluating various scenarios-even thinking about binary representations-before concluding with the right answer. This self-questioning and verification procedure, although it may seem ineffective at first look, could show useful in intricate tasks where much deeper reasoning is essential.

Prompt Engineering:

Traditional few-shot prompting strategies, which have worked well for numerous chat-based designs, can actually break down efficiency with R1. The designers recommend utilizing direct problem statements with a zero-shot technique that specifies the output format plainly. This ensures that the design isn't led astray by extraneous examples or hints that might interfere with its internal reasoning procedure.

Q&A

Q1: Which model deserves more attention - DeepSeek or Qwen2.5 Max?

A: While Qwen2.5 is also a strong model in the open-source community, the choice eventually depends upon your use case. DeepSeek R1 highlights advanced reasoning and a novel training approach that might be specifically important in tasks where proven reasoning is important.
