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, we dove deep into the development of the DeepSeek household - from the early models through DeepSeek V3 to the breakthrough R1. We also explored the technical developments that make R1 so unique in the world of open-source AI.

The DeepSeek Family Tree: From V3 to R1

DeepSeek isn't just a single model; it's a household of increasingly advanced AI systems. The advancement goes something like this:

DeepSeek V2:

This was the foundation model which leveraged a mixture-of-experts architecture, where only a subset of professionals are used at reasoning, drastically enhancing the processing time for each token. It also featured multi-head latent attention to reduce memory footprint.

DeepSeek V3:

This design presented FP8 training methods, which assisted drive down training costs by over 42.5% compared to previous models. FP8 is a less accurate method to keep weights inside the LLMs but can considerably enhance the memory footprint. However, training utilizing FP8 can typically be unsteady, and it is difficult to obtain the desired training outcomes. Nevertheless, DeepSeek uses numerous tricks and attains incredibly steady FP8 training. V3 set the stage as a highly efficient design that was already economical (with claims of being 90% more affordable than some closed-source options).

DeepSeek R1-Zero:

With V3 as the base, the team then introduced R1-Zero, the first reasoning-focused model. Here, the focus was on teaching the model not just to create responses but to "think" before answering. Using pure reinforcement learning, the design was motivated to produce intermediate thinking actions, for example, taking extra time (frequently 17+ seconds) to resolve an easy problem like "1 +1."

The crucial innovation here was the use of group relative policy optimization (GROP). Instead of depending on a standard procedure reward design (which would have needed annotating every action of the reasoning), GROP compares several outputs from the model. By sampling several potential answers and scoring them (using rule-based steps like specific match for math or verifying code outputs), the system discovers to favor thinking that results in the proper result without the requirement for specific supervision of every intermediate idea.

DeepSeek R1:

Recognizing that R1-Zero's without supervision method produced reasoning outputs that could be hard to check out or even mix languages, the developers went back to the drawing board. They utilized the raw outputs from R1-Zero to produce "cold start" information 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 model further-combining both reasoning-oriented reinforcement learning and monitored fine-tuning. The result is DeepSeek R1: a model that now produces legible, coherent, and trustworthy reasoning while still maintaining the performance and cost-effectiveness of its predecessors.

What Makes R1 Series Special?

The most fascinating element of R1 (absolutely no) is how it established thinking abilities without specific supervision of the reasoning process. It can be even more improved by using cold-start information and supervised support finding out to produce understandable reasoning on basic jobs. Here's what sets it apart:

Open Source & Efficiency:

R1 is open source, permitting scientists and developers to check and build upon its developments. Its expense performance is a significant selling point especially when compared to closed-source models (claimed 90% more affordable than OpenAI) that need huge calculate budgets.

Novel Training Approach:

Instead of relying exclusively on annotated reasoning (which is both costly and lengthy), the design was trained utilizing an outcome-based method. It started with quickly verifiable tasks, such as mathematics problems and coding exercises, where the accuracy of the final response might be quickly determined.

By utilizing group relative policy optimization, the training process compares several produced responses to determine which ones fulfill the desired output. This relative scoring system enables the design to discover "how to think" even when intermediate reasoning is produced in a freestyle manner.

Overthinking?

A fascinating observation is that DeepSeek R1 often "overthinks" basic issues. For instance, when asked "What is 1 +1?" it may invest almost 17 seconds examining various scenarios-even thinking about binary representations-before concluding with the correct response. This self-questioning and confirmation process, although it may seem ineffective at first glance, might prove beneficial in complicated jobs where much deeper thinking is necessary.

Prompt Engineering:

Traditional few-shot triggering techniques, which have worked well for many chat-based designs, can really degrade performance with R1. The designers recommend using direct problem declarations with a zero-shot method that defines the output format plainly. This makes sure that the design isn't led astray by extraneous examples or hints that might interfere with its internal reasoning procedure.

Q&A

Q1: Which model deserves more attention - DeepSeek or Qwen2.5 Max?

A: While Qwen2.5 is likewise a strong model in the open-source neighborhood, the option ultimately depends upon your use case. DeepSeek R1 highlights sophisticated thinking and a novel training technique that might be especially important in tasks where verifiable reasoning is crucial.
