We've been tracking the explosive increase of DeepSeek R1, which has taken the AI world by storm in recent weeks. In this session, we dove deep into the development of the DeepSeek family - from the early models through DeepSeek V3 to the development R1. We likewise explored the technical innovations that make R1 so special worldwide of open-source AI.

The DeepSeek Ancestral Tree: From V3 to R1

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

DeepSeek V2:

This was the structure model which leveraged a mixture-of-experts architecture, where only a subset of experts are utilized at inference, drastically improving the processing time for each token. It also featured multi-head latent attention to decrease memory footprint.

DeepSeek V3:

This model presented FP8 training methods, which helped drive down training expenses by over 42.5% compared to previous iterations. FP8 is a less accurate way to store weights inside the LLMs however can considerably improve the memory footprint. However, training using FP8 can generally be unsteady, and it is hard to obtain the preferred training results. Nevertheless, DeepSeek uses multiple techniques and attains remarkably steady FP8 training. V3 set the phase as an extremely 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 group then presented R1-Zero, the very first reasoning-focused iteration. Here, the focus was on teaching the design not simply to generate answers however to "think" before answering. Using pure reinforcement learning, the model was encouraged to generate intermediate thinking steps, for example, taking extra time (typically 17+ seconds) to work through a simple problem like "1 +1."

The key development here was the use of group relative policy optimization (GROP). Instead of depending on a conventional procedure reward design (which would have needed annotating every step of the thinking), GROP compares numerous outputs from the model. By sampling several potential answers and scoring them (utilizing rule-based steps like precise match for mathematics or verifying code outputs), the system finds out to prefer thinking that results in the appropriate outcome without the need for specific guidance of every intermediate thought.

DeepSeek R1:

Recognizing that R1-Zero's unsupervised method produced reasoning outputs that could be difficult to check out or perhaps mix languages, the designers returned to the drawing board. They used the raw outputs from R1-Zero to produce "cold start" data and after that by hand curated these examples to filter and improve the quality of the reasoning. This human post-processing was then utilized to tweak the original DeepSeek V3 design further-combining both reasoning-oriented support learning and monitored fine-tuning. The outcome is DeepSeek R1: a design that now produces readable, meaningful, and dependable reasoning while still maintaining the efficiency and cost-effectiveness of its predecessors.

What Makes R1 Series Special?

The most interesting aspect of R1 (no) is how it established reasoning capabilities without specific supervision of the thinking process. It can be even more enhanced by utilizing cold-start information and supervised reinforcement finding out to produce understandable thinking on basic tasks. Here's what sets it apart:

Open Source & Efficiency:

R1 is open source, permitting researchers and designers to inspect and construct upon its innovations. Its cost performance is a major selling point especially when compared to closed-source models (claimed 90% cheaper than OpenAI) that require enormous calculate budgets.

Novel Training Approach:

Instead of relying exclusively on annotated thinking (which is both costly and lengthy), the model was trained using an outcome-based method. It started with quickly verifiable jobs, such as mathematics problems and coding workouts, where the accuracy of the final answer might be easily determined.

By utilizing group relative policy optimization, the training procedure compares numerous created answers to figure out which ones fulfill the preferred output. This relative scoring mechanism enables the model to learn "how to think" even when intermediate reasoning is created in a freestyle way.

Overthinking?

A fascinating observation is that DeepSeek R1 often "overthinks" easy problems. For instance, when asked "What is 1 +1?" it may invest nearly 17 seconds assessing different scenarios-even thinking about binary representations-before concluding with the appropriate response. This self-questioning and confirmation procedure, although it might seem ineffective at very first glimpse, might show helpful in complex tasks where much deeper reasoning is essential.

Prompt Engineering:

Traditional few-shot prompting methods, which have worked well for many chat-based models, can in fact break down efficiency with R1. The developers suggest utilizing direct issue statements with a zero-shot technique that defines the output format plainly. This makes sure that the model isn't led astray by extraneous examples or tips that may interfere with its internal thinking procedure.
