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 evolution 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 Family Tree: From V3 to R1

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

DeepSeek V2:

This was the foundation design which leveraged a mixture-of-experts architecture, where just a subset of experts are used at reasoning, considerably improving the processing time for each token. It also featured multi-head hidden attention to decrease memory footprint.

DeepSeek V3:

This design introduced FP8 training techniques, which helped drive down training costs by over 42.5% compared to previous iterations. FP8 is a less exact way to store weights inside the LLMs however can greatly improve the memory footprint. However, training utilizing FP8 can typically be unstable, and it is difficult to obtain the preferred training results. Nevertheless, DeepSeek uses numerous tricks and attains remarkably stable FP8 training. V3 set the stage as an extremely efficient design that was already cost-efficient (with claims of being 90% cheaper than some closed-source alternatives).

DeepSeek R1-Zero:

With V3 as the base, the group then presented R1-Zero, the first reasoning-focused iteration. Here, the focus was on teaching the model not simply to create but to "think" before answering. Using pure support learning, the design was encouraged to produce intermediate thinking actions, for instance, taking additional time (typically 17+ seconds) to work through a basic issue like "1 +1."

The crucial development here was using group relative policy optimization (GROP). Instead of relying on a traditional procedure reward design (which would have needed annotating every action of the reasoning), GROP compares numerous outputs from the model. By sampling a number of potential answers and scoring them (utilizing rule-based procedures like exact match for math or verifying code outputs), the system discovers to prefer reasoning that causes the correct outcome without the need for explicit guidance of every intermediate idea.

DeepSeek R1:

Recognizing that R1-Zero's not being watched technique produced reasoning outputs that might be difficult to read or even blend languages, the designers went back to the drawing board. They used the raw outputs from R1-Zero to generate "cold start" data and after that manually curated these examples to filter and improve the quality of the thinking. This human post-processing was then utilized to tweak the initial DeepSeek V3 design further-combining both reasoning-oriented reinforcement knowing and monitored fine-tuning. The outcome is DeepSeek R1: a model that now produces readable, coherent, and trusted thinking while still maintaining the effectiveness and cost-effectiveness of its predecessors.

What Makes R1 Series Special?

The most interesting element of R1 (absolutely no) is how it developed thinking abilities without explicit guidance of the thinking process. It can be even more enhanced by utilizing cold-start data and monitored reinforcement finding out to produce readable reasoning on general tasks. Here's what sets it apart:

Open Source & Efficiency:

R1 is open source, allowing scientists and developers to check and build upon its innovations. Its cost performance is a major selling point particularly when compared to closed-source models (claimed 90% more affordable than OpenAI) that require massive calculate spending plans.

Novel Training Approach:

Instead of relying solely on annotated thinking (which is both pricey and lengthy), the design was trained utilizing an outcome-based method. It started with easily proven jobs, such as math issues and coding workouts, where the accuracy of the last response could be quickly measured.

By utilizing group relative policy optimization, the training process compares numerous generated responses to determine which ones fulfill the wanted output. This relative scoring system allows the model to find out "how to think" even when intermediate reasoning is created in a freestyle manner.

Overthinking?

An interesting observation is that DeepSeek R1 often "overthinks" simple problems. For instance, when asked "What is 1 +1?" it might spend nearly 17 seconds examining various scenarios-even considering binary representations-before concluding with the right answer. This self-questioning and confirmation process, although it may appear inefficient initially look, might prove advantageous in intricate tasks where much deeper reasoning is essential.

Prompt Engineering:

Traditional few-shot triggering techniques, which have actually worked well for lots of chat-based designs, can actually degrade performance with R1. The developers suggest utilizing direct issue statements with a zero-shot technique that specifies the output format plainly. This ensures that the design isn't led astray by extraneous examples or hints that might interfere with its internal reasoning procedure.
