We've been tracking the explosive increase of DeepSeek R1, which has actually taken the AI world by storm in current weeks. In this session, setiathome.berkeley.edu we dove deep into the evolution of the DeepSeek family - from the early designs through DeepSeek V3 to the development R1. We likewise checked out the technical developments that make R1 so unique in the world of open-source AI.

The DeepSeek Family Tree: bytes-the-dust.com From V3 to R1

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

DeepSeek V2:

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

DeepSeek V3:

This model presented FP8 training methods, which helped drive down training costs by over 42.5% compared to previous versions. FP8 is a less accurate method to store weights inside the LLMs but can significantly enhance the memory footprint. However, training utilizing FP8 can usually be unstable, and it is hard to obtain the desired training outcomes. Nevertheless, DeepSeek utilizes numerous techniques and attains incredibly stable FP8 training. V3 set the phase as a highly efficient design that was already economical (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 very first reasoning-focused model. Here, the focus was on teaching the design not just to create answers but to "think" before answering. Using pure support learning, the design was motivated to generate intermediate reasoning steps, for instance, taking additional time (typically 17+ seconds) to resolve a simple problem like "1 +1."

The essential development here was the use of group relative policy optimization (GROP). Instead of relying on a standard procedure benefit design (which would have required annotating every action of the thinking), GROP compares numerous outputs from the design. By tasting numerous possible responses and scoring them (utilizing rule-based steps like exact match for mathematics or confirming code outputs), the system discovers to favor reasoning that results in the right outcome without the need for specific guidance of every intermediate idea.

DeepSeek R1:

Recognizing that R1-Zero's not being watched technique produced reasoning outputs that could be hard to check out or perhaps blend languages, the developers went back to the drawing board. They utilized the raw outputs from R1-Zero to generate "cold start" data and then manually curated these examples to filter and enhance the quality of the reasoning. This human post-processing was then utilized to tweak the initial DeepSeek V3 model further-combining both reasoning-oriented support learning and monitored fine-tuning. The result is DeepSeek R1: a design 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 fascinating aspect of R1 (no) is how it established thinking abilities without explicit guidance of the reasoning process. It can be even more improved by utilizing cold-start data and supervised reinforcement learning to produce legible reasoning on basic tasks. Here's what sets it apart:

Open Source & Efficiency:

R1 is open source, enabling researchers and developers to examine and build upon its developments. Its expense efficiency is a significant selling point particularly when compared to closed-source models (claimed 90% more affordable than OpenAI) that need massive calculate budget plans.

Novel Training Approach:

Instead of relying solely on annotated thinking (which is both expensive and time-consuming), the model was trained using an outcome-based method. It started with quickly verifiable tasks, such as math issues and coding workouts, where the correctness of the final response might be quickly measured.

By utilizing group relative policy optimization, the training process compares numerous produced answers to identify which ones fulfill the desired output. This relative scoring mechanism permits the model to discover "how to think" even when intermediate reasoning is produced in a freestyle way.

Overthinking?

An interesting observation is that DeepSeek R1 in some cases "overthinks" simple problems. For example, when asked "What is 1 +1?" it might invest nearly 17 seconds assessing various scenarios-even considering binary representations-before concluding with the proper response. This self-questioning and confirmation procedure, although it may appear ineffective at first glimpse, might prove useful in intricate tasks where much deeper reasoning is essential.

Prompt Engineering:

Traditional few-shot prompting methods, which have actually worked well for numerous chat-based designs, can really deteriorate performance with R1. The developers advise using direct issue declarations with a zero-shot method that defines the output format plainly. This guarantees that the design isn't led astray by extraneous examples or tips that may interfere with its internal thinking procedure.
