We've been tracking the explosive rise of DeepSeek R1, setiathome.berkeley.edu which has taken the AI world by storm in recent weeks. In this session, we dove deep into the advancement of the DeepSeek family - from the early designs through DeepSeek V3 to the breakthrough R1. We also explored the technical innovations that make R1 so unique on the planet of open-source AI.

The DeepSeek Ancestral Tree: From V3 to R1

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

DeepSeek V2:

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

DeepSeek V3:

This model introduced FP8 training techniques, which assisted drive down training costs by over 42.5% compared to previous versions. FP8 is a less accurate method to store weights inside the LLMs however can greatly enhance the memory footprint. However, training using FP8 can normally be unsteady, and it is difficult to obtain the preferred training outcomes. Nevertheless, DeepSeek uses numerous tricks and attains remarkably stable FP8 training. V3 set the phase as a highly efficient design that was already cost-efficient (with claims of being 90% less expensive than some closed-source alternatives).

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 answering. Using pure support knowing, the model was encouraged to produce intermediate reasoning steps, for example, taking extra time (typically 17+ seconds) to overcome a simple problem like "1 +1."

The key innovation here was making use of group relative policy optimization (GROP). Instead of counting on a standard procedure reward model (which would have required annotating every action of the thinking), GROP compares several outputs from the model. By sampling several potential answers and scoring them (using rule-based procedures like exact match for math or confirming code outputs), the system finds out to prefer reasoning that leads to the proper outcome without the need for specific supervision of every intermediate thought.

DeepSeek R1:

Recognizing that R1-Zero's without supervision method produced thinking outputs that might be difficult to read and even blend languages, the developers 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 reasoning. This human post-processing was then used to fine-tune the initial DeepSeek V3 model further-combining both reasoning-oriented reinforcement knowing and supervised fine-tuning. The result is DeepSeek R1: a design that now produces understandable, coherent, and reputable reasoning while still maintaining the effectiveness and cost-effectiveness of its predecessors.

What Makes R1 Series Special?

The most fascinating aspect of R1 (no) is how it established reasoning capabilities without explicit supervision of the thinking process. It can be even more improved by utilizing cold-start information and monitored support finding out to produce readable thinking on basic tasks. Here's what sets it apart:

Open Source & Efficiency:

R1 is open source, permitting researchers and developers to examine and build upon its developments. Its cost performance is a major selling point specifically when compared to closed-source designs (claimed 90% cheaper than OpenAI) that need huge calculate spending plans.

Novel Training Approach:

Instead of relying exclusively on annotated reasoning (which is both costly and time-consuming), the design was trained utilizing an outcome-based approach. It started with easily verifiable jobs, such as mathematics issues and coding workouts, where the correctness of the final answer might be quickly measured.

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

Overthinking?

An intriguing observation is that DeepSeek R1 often "overthinks" basic problems. For example, when asked "What is 1 +1?" it may spend almost 17 seconds evaluating various scenarios-even thinking about binary representations-before concluding with the correct response. This self-questioning and verification procedure, although it might seem ineffective in the beginning look, could prove beneficial in complex jobs where deeper reasoning is needed.

Prompt Engineering:

Traditional few-shot prompting strategies, which have worked well for numerous chat-based designs, can in fact degrade performance with R1. The developers suggest using direct issue declarations 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 hints that might hinder its internal reasoning process.
