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 evolution of the DeepSeek family - from the early models through DeepSeek V3 to the advancement R1. We likewise checked out the technical innovations that make R1 so special in the world of open-source AI.

The DeepSeek Family Tree: From V3 to R1

DeepSeek isn't just a single design; it's a family of significantly 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 experts are utilized at inference, drastically enhancing the processing time for each token. It also featured multi-head hidden attention to lower memory footprint.

DeepSeek V3:

This model introduced FP8 training methods, which helped drive down training costs by over 42.5% compared to previous iterations. FP8 is a less precise way to keep weights inside the LLMs however can greatly enhance the memory footprint. However, training utilizing FP8 can usually be unsteady, and it is tough to obtain the preferred training outcomes. Nevertheless, DeepSeek utilizes numerous techniques and attains incredibly steady FP8 training. V3 set the stage as an extremely efficient model that was already cost-effective (with claims of being 90% less expensive than some closed-source options).

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 model not simply to create answers but to "believe" before addressing. Using pure reinforcement learning, the model was encouraged to generate intermediate thinking actions, for instance, taking additional time (typically 17+ seconds) to overcome a basic issue like "1 +1."

The crucial innovation here was using group relative policy optimization (GROP). Instead of depending on a conventional process reward design (which would have required annotating every step of the reasoning), GROP compares several outputs from the model. By tasting several possible responses and scoring them (using rule-based steps like exact match for mathematics or validating code outputs), the system learns to favor reasoning that results in the correct outcome without the need for specific supervision of every intermediate thought.

DeepSeek R1:

Recognizing that R1-Zero's without supervision technique produced thinking outputs that could be hard to read or perhaps blend languages, the designers went back to the drawing board. They used the raw outputs from R1-Zero to create "cold start" data and then manually curated these examples to filter and enhance the quality of the thinking. This human post-processing was then utilized to fine-tune the original DeepSeek V3 design further-combining both reasoning-oriented reinforcement learning and supervised fine-tuning. The outcome is DeepSeek R1: a design that now produces legible, meaningful, and reputable thinking while still maintaining the effectiveness and cost-effectiveness of its predecessors.

What Makes R1 Series Special?

The most remarkable element of R1 (absolutely no) is how it established reasoning abilities without specific guidance of the reasoning procedure. It can be even more enhanced by utilizing cold-start information and monitored support finding out to produce understandable thinking on basic tasks. Here's what sets it apart:

Open Source & Efficiency:

R1 is open source, permitting scientists and developers to check and develop upon its innovations. Its cost efficiency is a major selling point particularly when compared to closed-source models (claimed 90% more affordable than OpenAI) that require huge calculate budgets.

Novel Training Approach:

Instead of relying exclusively on annotated reasoning (which is both expensive and time-consuming), the design was trained utilizing an outcome-based method. It began with easily proven tasks, 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 numerous generated answers to identify which ones satisfy the preferred output. This relative scoring system enables the model to find out "how to think" even when intermediate thinking is generated in a freestyle manner.

Overthinking?

An intriguing observation is that DeepSeek R1 often "overthinks" easy problems. For example, when asked "What is 1 +1?" it might invest almost 17 seconds assessing various scenarios-even considering binary representations-before concluding with the correct response. This self-questioning and confirmation procedure, although it might appear ineffective in the beginning glance, could show useful in complicated jobs where deeper thinking is necessary.

Prompt Engineering:

Traditional few-shot triggering methods, which have actually worked well for many chat-based designs, can really deteriorate performance with R1. The designers advise utilizing direct issue declarations with a zero-shot approach that defines the output format plainly. This makes sure that the design isn't led astray by extraneous examples or tips that might hinder its internal thinking procedure.
