We've been tracking the explosive rise of DeepSeek R1, which has actually taken the AI world by storm in recent weeks. In this session, we dove deep into the evolution of the DeepSeek family - from the early designs through DeepSeek V3 to the advancement R1. We also checked out the technical developments that make R1 so special in the world of open-source AI.

The DeepSeek Family Tree: From V3 to R1

DeepSeek isn't just a single design; it's a family of significantly advanced AI systems. The evolution goes something like this:

DeepSeek V2:

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

DeepSeek V3:

This model introduced FP8 training techniques, which assisted drive down training expenses by over 42.5% compared to previous iterations. FP8 is a less precise method to store weights inside the LLMs but can significantly improve the memory footprint. However, training using FP8 can typically be unsteady, and it is hard to obtain the wanted training results. Nevertheless, DeepSeek utilizes multiple techniques and attains remarkably stable FP8 training. V3 set the phase as a highly efficient model that was currently cost-effective (with claims of being 90% cheaper than some closed-source options).

DeepSeek R1-Zero:

With V3 as the base, the team then presented R1-Zero, the very first reasoning-focused model. Here, the focus was on teaching the model not simply to create responses but to "think" before responding to. Using pure reinforcement learning, the model was motivated to produce intermediate thinking steps, for instance, taking extra time (frequently 17+ seconds) to work through an easy issue like "1 +1."

The crucial development here was using group relative policy optimization (GROP). Instead of counting on a traditional process benefit model (which would have needed annotating every action of the reasoning), GROP compares several outputs from the design. By tasting a number of possible answers and scoring them (using rule-based steps like specific match for mathematics or confirming code outputs), the system finds out to prefer reasoning that results in the right result without the need for explicit supervision of every intermediate idea.

DeepSeek R1:

Recognizing that R1-Zero's not being watched method produced reasoning outputs that could be difficult to read and even blend languages, the developers returned to the drawing board. They utilized the raw outputs from R1-Zero to produce "cold start" data and after that by hand curated these examples to filter and enhance the quality of the thinking. This human post-processing was then used to tweak the initial DeepSeek V3 model further-combining both reasoning-oriented reinforcement learning and supervised fine-tuning. The result is DeepSeek R1: a design that now produces readable, coherent, and dependable thinking 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 developed reasoning capabilities without explicit guidance of the reasoning procedure. It can be further improved by utilizing cold-start information and supervised reinforcement finding out to produce readable reasoning on basic tasks. Here's what sets it apart:

Open Source & Efficiency:

R1 is open source, allowing scientists and developers to check and build upon its developments. Its cost performance is a significant selling point especially when compared to closed-source models (claimed 90% less expensive than OpenAI) that require massive calculate budget plans.

Novel Training Approach:

Instead of relying entirely on annotated reasoning (which is both pricey and lengthy), the model was trained using an outcome-based technique. It began with quickly verifiable tasks, such as mathematics problems and coding exercises, where the accuracy of the final response might be quickly determined.

By using group relative policy optimization, the training procedure compares numerous generated responses to identify which ones meet the desired output. This relative scoring mechanism allows the model to discover "how to believe" even when intermediate thinking is produced in a freestyle way.

Overthinking?

A fascinating observation is that DeepSeek R1 often "overthinks" easy issues. For example, when asked "What is 1 +1?" it might invest almost 17 seconds evaluating various scenarios-even considering binary representations-before concluding with the appropriate response. This self-questioning and verification process, although it might appear inefficient at very first glance, could show useful in complex jobs where much deeper reasoning is needed.

Prompt Engineering:

Traditional few-shot triggering methods, which have worked well for lots of chat-based models, can really deteriorate efficiency with R1. The designers advise utilizing direct issue statements with a zero-shot method that defines the output format plainly. This ensures that the model isn't led astray by extraneous examples or tips that might interfere with its internal thinking procedure.
