We've been tracking the explosive increase of DeepSeek R1, which has actually 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 development R1. We also explored the technical developments that make R1 so special in the world of open-source AI.

The DeepSeek Ancestral Tree: From V3 to R1

DeepSeek isn't just a single design; it's a household of progressively sophisticated 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 experts are used at reasoning, drastically improving the processing time for each token. It also included multi-head latent attention to decrease memory footprint.

DeepSeek V3:

This design presented FP8 training techniques, which assisted drive down training expenses by over 42.5% compared to previous iterations. FP8 is a less accurate method to keep weights inside the LLMs however can considerably enhance the memory footprint. However, training using FP8 can normally be unstable, and it is difficult to obtain the desired training outcomes. Nevertheless, DeepSeek uses several tricks and attains incredibly stable FP8 training. V3 set the stage as an extremely effective design that was already 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 design not simply to produce responses however to "think" before responding to. Using pure reinforcement learning, the design was motivated to create intermediate reasoning steps, for example, taking additional time (often 17+ seconds) to resolve a basic problem like "1 +1."

The crucial innovation here was using group relative policy optimization (GROP). Instead of depending on a standard process benefit design (which would have required annotating every step of the thinking), GROP compares multiple outputs from the design. By sampling numerous prospective answers and scoring them (using rule-based procedures like exact match for math or verifying code outputs), the system finds out to prefer reasoning that results in the proper outcome without the need for explicit supervision of every intermediate idea.

DeepSeek R1:

Recognizing that R1-Zero's not being watched method produced reasoning outputs that could be difficult to read or perhaps blend languages, the designers returned to the drawing board. They utilized the raw outputs from R1-Zero to produce "cold start" data and then 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 supervised fine-tuning. The outcome is DeepSeek R1: a model that now produces understandable, coherent, and reputable thinking while still maintaining the efficiency and cost-effectiveness of its predecessors.

What Makes R1 Series Special?

The most interesting aspect of R1 (zero) is how it established thinking capabilities without specific guidance of the reasoning procedure. It can be further enhanced by utilizing cold-start data and supervised reinforcement learning to produce readable reasoning on general tasks. Here's what sets it apart:

Open Source & Efficiency:

R1 is open source, allowing researchers and developers to inspect and construct upon its innovations. Its cost efficiency is a significant selling point especially when compared to closed-source designs (claimed 90% more affordable than OpenAI) that require huge calculate spending plans.

Novel Training Approach:

Instead of relying solely on annotated reasoning (which is both costly and lengthy), the design was trained using an outcome-based technique. It started with quickly verifiable tasks, such as math issues and coding workouts, where the accuracy of the final answer could be quickly measured.

By utilizing group relative policy optimization, the training procedure compares multiple generated answers to determine which ones satisfy the desired output. This relative scoring mechanism permits the design to learn "how to think" even when intermediate thinking is produced in a freestyle manner.

Overthinking?

A fascinating observation is that DeepSeek R1 in some cases "overthinks" easy issues. For instance, when asked "What is 1 +1?" it might spend almost 17 seconds examining different scenarios-even considering binary representations-before concluding with the correct answer. This self-questioning and confirmation process, although it might seem ineffective in the beginning glimpse, might show beneficial in where much deeper thinking is essential.

Prompt Engineering:

Traditional few-shot prompting strategies, which have actually worked well for lots of chat-based models, can really deteriorate efficiency with R1. The developers suggest utilizing direct problem declarations with a zero-shot technique that specifies the output format plainly. This guarantees that the model isn't led astray by extraneous examples or tips that might interfere with its internal thinking process.
