We've been tracking the explosive rise 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 designs through DeepSeek V3 to the breakthrough R1. We also checked out the technical developments that make R1 so special worldwide of open-source AI.

The DeepSeek Family Tree: From V3 to R1

DeepSeek isn't simply a single design; it's a family 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 just a subset of specialists are utilized at reasoning, drastically improving the processing time for each token. It also featured multi-head latent attention to minimize memory footprint.

DeepSeek V3:

This model introduced FP8 training techniques, which assisted drive down training costs by over 42.5% compared to previous versions. FP8 is a less exact method to keep weights inside the LLMs however can significantly improve the memory footprint. However, training utilizing FP8 can generally be unstable, and it is tough to obtain the preferred training results. Nevertheless, DeepSeek utilizes several tricks and attains extremely stable FP8 training. V3 set the stage as a highly effective model that was currently economical (with claims of being 90% more affordable than some closed-source alternatives).

DeepSeek R1-Zero:

With V3 as the base, the group then presented R1-Zero, the very first reasoning-focused version. Here, the focus was on teaching the design not simply to generate answers however to "think" before addressing. Using pure reinforcement knowing, the model was motivated to produce intermediate thinking steps, for instance, taking extra time (typically 17+ seconds) to resolve an easy problem like "1 +1."

The crucial innovation here was making use of group relative policy optimization (GROP). Instead of depending on a standard process reward design (which would have required annotating every action of the thinking), GROP compares numerous outputs from the model. By sampling a number of possible responses and scoring them (utilizing rule-based steps like specific match for math or verifying code outputs), the system finds out to favor reasoning that leads to the appropriate outcome without the requirement for specific supervision of every intermediate thought.

DeepSeek R1:

Recognizing that R1-Zero's without supervision approach produced reasoning outputs that might be difficult to read or even mix languages, the designers returned to the drawing board. They utilized the raw outputs from R1-Zero to produce "cold start" information and then by hand curated these examples to filter and improve the quality of the thinking. This human post-processing was then used to fine-tune the original DeepSeek V3 design further-combining both reasoning-oriented reinforcement learning and monitored fine-tuning. The result is DeepSeek R1: a design that now produces understandable, coherent, and reputable reasoning 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 reasoning abilities without explicit guidance of the reasoning process. It can be even more enhanced by utilizing cold-start data and monitored reinforcement learning to produce legible thinking on general jobs. Here's what sets it apart:

Open Source & Efficiency:

R1 is open source, permitting scientists and designers to inspect and develop upon its innovations. Its cost effectiveness is a significant selling point especially when compared to closed-source designs (claimed 90% cheaper than OpenAI) that need massive compute budget plans.

Novel Training Approach:

Instead of relying entirely on annotated thinking (which is both costly and time-consuming), the model was trained utilizing an outcome-based method. It began with quickly proven tasks, such as mathematics problems and coding workouts, where the accuracy of the final response might be easily measured.

By utilizing group relative policy optimization, the training procedure compares several generated responses to determine which ones fulfill the preferred output. This relative scoring system allows the model to learn "how to think" even when intermediate reasoning is generated 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 may invest nearly 17 seconds evaluating different scenarios-even thinking about binary representations-before concluding with the proper answer. This self-questioning and verification process, although it might seem ineffective at very first glance, might prove beneficial in complex tasks where deeper thinking is required.

Prompt Engineering:

Traditional few-shot prompting methods, which have actually worked well for numerous chat-based designs, can in fact degrade performance with R1. The designers suggest using direct issue declarations with a zero-shot approach that defines the output format plainly. This makes sure that the model isn't led astray by extraneous examples or hints that might disrupt its internal reasoning procedure.
