We've been tracking the explosive increase of DeepSeek R1, which has taken the AI world by storm in current weeks. In this session, we dove deep into the development of the DeepSeek family - from the early designs through DeepSeek V3 to the advancement R1. We also explored the technical developments that make R1 so unique in the world of open-source AI.

The DeepSeek Ancestral Tree: From V3 to R1

DeepSeek isn't simply a single model; it's a household of increasingly 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 inference, considerably enhancing the processing time for each token. It also featured multi-head hidden attention to reduce memory footprint.

DeepSeek V3:

This model introduced FP8 training techniques, which helped drive down training costs by over 42.5% compared to previous iterations. FP8 is a less accurate method to store weights inside the LLMs however can greatly improve the memory footprint. However, training using FP8 can usually be unstable, and it is hard to obtain the wanted training results. Nevertheless, DeepSeek uses multiple techniques and attains incredibly stable FP8 training. V3 set the stage as a highly efficient design that was currently economical (with claims of being 90% cheaper than some closed-source alternatives).

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 just to generate answers however to "think" before addressing. Using pure reinforcement learning, the model was motivated to produce intermediate thinking actions, for example, taking additional time (often 17+ seconds) to resolve a simple issue like "1 +1."

The essential development here was the usage of group relative policy optimization (GROP). Instead of counting on a conventional process benefit design (which would have needed annotating every step of the thinking), GROP compares multiple outputs from the model. By sampling numerous prospective responses and scoring them (utilizing rule-based measures like exact match for math or confirming code outputs), the system learns to favor thinking that results in the correct result without the requirement for specific guidance of every intermediate idea.

DeepSeek R1:

Recognizing that R1-Zero's without supervision method produced thinking outputs that might be tough to read or even blend languages, the developers went back to the drawing board. They utilized the raw outputs from R1-Zero to generate "cold start" information and then manually curated these examples to filter and enhance 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 supervised fine-tuning. The outcome is DeepSeek R1: a design that now produces readable, coherent, and trustworthy thinking while still maintaining the effectiveness and cost-effectiveness of its predecessors.

What Makes R1 Series Special?

The most interesting aspect of R1 (zero) is how it developed reasoning capabilities without explicit supervision of the reasoning procedure. It can be even more enhanced by using cold-start information and monitored reinforcement finding out to produce readable thinking on basic jobs. Here's what sets it apart:

Open Source & Efficiency:

R1 is open source, allowing researchers and developers to examine and build upon its developments. Its cost effectiveness is a significant selling point especially when compared to closed-source models (claimed 90% cheaper than OpenAI) that need huge compute budgets.

Novel Training Approach:

Instead of relying solely on annotated thinking (which is both pricey and time-consuming), the model was trained using an outcome-based approach. It started with easily proven tasks, such as math problems and coding exercises, where the correctness of the final answer could be easily measured.

By using group relative policy optimization, the training procedure compares multiple produced responses to determine which ones satisfy the desired output. This relative scoring mechanism allows the model to learn "how to believe" even when intermediate reasoning is created in a freestyle manner.

Overthinking?

An interesting observation is that DeepSeek R1 often "overthinks" easy issues. For example, when asked "What is 1 +1?" it may spend nearly 17 seconds examining various scenarios-even thinking about binary representations-before concluding with the appropriate response. This self-questioning and confirmation procedure, although it may seem ineffective in the beginning glance, might show beneficial in complex jobs where much deeper reasoning is needed.

Prompt Engineering:

Traditional few-shot triggering strategies, which have worked well for lots of chat-based designs, can actually degrade performance with R1. The designers advise using direct problem statements with a zero-shot method that specifies the output format plainly. This guarantees that the model isn't led astray by extraneous examples or hints that might disrupt its internal reasoning procedure.
