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 evolution of the DeepSeek family - from the early models through DeepSeek V3 to the breakthrough R1. We likewise checked out the technical innovations that make R1 so unique in the world of open-source AI.

The DeepSeek Family Tree: From V3 to R1

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

DeepSeek V2:

This was the foundation model which leveraged a mixture-of-experts architecture, where just a subset of professionals are utilized at reasoning, significantly improving the processing time for each token. It likewise featured multi-head hidden attention to lower memory footprint.

DeepSeek V3:

This model introduced FP8 training strategies, which helped 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 enhance the memory footprint. However, training using FP8 can usually be unstable, and it is difficult to obtain the wanted training outcomes. Nevertheless, DeepSeek utilizes multiple tricks and attains remarkably stable FP8 training. V3 set the stage as an extremely effective model that was already cost-effective (with claims of being 90% more affordable than some closed-source alternatives).

DeepSeek R1-Zero:

With V3 as the base, the team then introduced R1-Zero, the very first reasoning-focused version. Here, the focus was on teaching the model not simply to generate responses however to "believe" before responding to. Using pure support knowing, the design was motivated to produce intermediate thinking actions, for example, taking extra time (typically 17+ seconds) to resolve an easy problem like "1 +1."

The key innovation here was making use of group relative policy optimization (GROP). Instead of counting on a traditional procedure reward design (which would have needed annotating every step of the thinking), GROP compares several outputs from the model. By sampling several prospective answers and scoring them (using rule-based measures like precise match for math or confirming code outputs), the system finds out to prefer thinking that leads to the appropriate outcome without the requirement for specific guidance of every intermediate thought.

DeepSeek R1:

Recognizing that R1-Zero's not being watched technique produced thinking outputs that might be difficult to read and even blend languages, the developers returned to the drawing board. They used the raw outputs from R1-Zero to produce "cold start" information and then manually curated these examples to filter and enhance the quality of the reasoning. This human post-processing was then used to fine-tune the original DeepSeek V3 model further-combining both reasoning-oriented support learning and monitored fine-tuning. The outcome is DeepSeek R1: a model that now produces legible, coherent, and dependable thinking while still maintaining the performance and cost-effectiveness of its predecessors.

What Makes R1 Series Special?

The most interesting aspect of R1 (absolutely no) is how it established reasoning capabilities without explicit supervision of the reasoning procedure. It can be even more enhanced by using cold-start information and monitored reinforcement discovering to produce readable reasoning on basic jobs. Here's what sets it apart:

Open Source & Efficiency:

R1 is open source, permitting researchers and designers to check and construct upon its developments. Its cost efficiency is a major selling point especially when compared to closed-source designs (claimed 90% cheaper than OpenAI) that require massive compute spending plans.

Novel Training Approach:

Instead of relying solely on annotated thinking (which is both costly and time-consuming), the model was trained utilizing an outcome-based technique. It started with easily proven tasks, such as math problems and coding exercises, where the correctness of the last response could be easily determined.

By using group relative policy optimization, the training process compares numerous created responses to figure out which ones meet the preferred output. This relative scoring system permits the model to discover "how to think" even when intermediate thinking is created in a freestyle manner.

Overthinking?

An intriguing observation is that DeepSeek R1 in some cases "overthinks" simple problems. For example, when asked "What is 1 +1?" it may spend nearly 17 seconds examining various scenarios-even considering binary representations-before concluding with the proper answer. This self-questioning and verification procedure, although it might seem inefficient at first look, could prove advantageous in intricate tasks where deeper reasoning is necessary.

Prompt Engineering:

Traditional few-shot prompting methods, which have worked well for lots of chat-based designs, can really break down efficiency with R1. The designers recommend using direct problem declarations with a zero-shot approach that defines the output format plainly. This guarantees that the design isn't led astray by extraneous examples or hints that may interfere with its internal reasoning process.
