We've been tracking the explosive rise of DeepSeek R1, which has 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 advancement R1. We also checked out the technical innovations that make R1 so unique worldwide of open-source AI.

The DeepSeek Ancestral Tree: From V3 to R1

DeepSeek isn't simply a single design; it's a household of progressively sophisticated AI systems. The advancement goes something like this:

DeepSeek V2:

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

DeepSeek V3:

This design presented FP8 training techniques, which helped drive down training costs by over 42.5% compared to previous models. FP8 is a less precise way to keep weights inside the LLMs however can significantly enhance the memory footprint. However, training using FP8 can normally be unstable, and it is difficult to obtain the wanted training results. Nevertheless, DeepSeek uses multiple techniques and attains remarkably stable FP8 training. V3 set the phase as an extremely efficient design that was currently affordable (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 version. Here, the focus was on teaching the model not simply to create responses but to "think" before addressing. Using pure support learning, the model was motivated to produce intermediate thinking actions, for example, taking extra time (typically 17+ seconds) to resolve a simple issue like "1 +1."

The crucial development here was using group relative policy optimization (GROP). Instead of depending on a standard procedure reward design (which would have required annotating every action of the reasoning), GROP compares multiple outputs from the model. By tasting numerous potential answers and scoring them (using rule-based steps like precise match for math or validating code outputs), the system discovers to prefer reasoning that results in the appropriate result without the need for specific guidance of every intermediate thought.

DeepSeek R1:

Recognizing that R1-Zero's not being watched technique produced thinking outputs that might be difficult to check out and even mix languages, the designers went back to the drawing board. They utilized the raw outputs from R1-Zero to produce "cold start" data and after that by hand curated these examples to filter and enhance the quality of the thinking. This human post-processing was then utilized to fine-tune the initial DeepSeek V3 model further-combining both reasoning-oriented reinforcement learning and monitored fine-tuning. The outcome is DeepSeek R1: a model that now produces readable, coherent, larsaluarna.se and reputable thinking while still maintaining the performance and cost-effectiveness of its predecessors.

What Makes R1 Series Special?

The most remarkable aspect of R1 (absolutely no) is how it established reasoning abilities without explicit supervision of the reasoning procedure. It can be further improved by using cold-start information and supervised reinforcement discovering to produce understandable thinking on general jobs. Here's what sets it apart:

Open Source & Efficiency:

R1 is open source, enabling researchers and developers to examine and construct upon its developments. Its cost efficiency is a significant selling point specifically when compared to closed-source models (claimed 90% less expensive than OpenAI) that need massive compute budgets.

Novel Training Approach:

Instead of relying entirely on annotated reasoning (which is both expensive and time-consuming), the model was trained utilizing an outcome-based approach. It started with quickly proven jobs, such as math issues and coding workouts, where the correctness of the final response might be quickly determined.

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

Overthinking?

An interesting observation is that DeepSeek R1 sometimes "overthinks" basic issues. For example, when asked "What is 1 +1?" it might invest almost 17 seconds evaluating various scenarios-even considering binary representations-before concluding with the right response. This self-questioning and verification process, although it may seem inefficient at first glance, might prove advantageous in complicated tasks where much deeper reasoning is needed.

Prompt Engineering:

Traditional few-shot triggering methods, which have worked well for numerous chat-based designs, can really deteriorate efficiency with R1. The developers recommend utilizing direct problem statements with a zero-shot approach that specifies the output format plainly. This makes sure that the model isn't led astray by extraneous examples or tips that might disrupt its internal reasoning process.
