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 household - from the early models through DeepSeek V3 to the development R1. We also checked out the technical developments that make R1 so special on the planet of open-source AI.

The DeepSeek Family Tree: From V3 to R1

DeepSeek isn't just a single model; it's a family of progressively sophisticated AI systems. The evolution goes something like this:

DeepSeek V2:

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

DeepSeek V3:

This design introduced FP8 training strategies, which helped drive down training expenses by over 42.5% compared to previous iterations. FP8 is a less accurate method to save weights inside the LLMs but can greatly enhance the memory footprint. However, training using FP8 can generally be unsteady, and it is hard to obtain the preferred training results. Nevertheless, DeepSeek utilizes multiple techniques and attains extremely steady FP8 training. V3 set the stage as an extremely efficient design that was currently cost-efficient (with claims of being 90% less expensive than some closed-source alternatives).

DeepSeek R1-Zero:

With V3 as the base, the team then presented R1-Zero, the first reasoning-focused iteration. Here, the focus was on teaching the design not just to generate answers however to "think" before responding to. Using pure reinforcement knowing, the design was motivated to generate intermediate thinking actions, for example, taking extra time (often 17+ seconds) to resolve an easy issue like "1 +1."

The key development here was making use of group relative policy optimization (GROP). Instead of relying on a standard process reward model (which would have required annotating every step of the reasoning), GROP compares several outputs from the design. By sampling a number of possible responses and scoring them (utilizing rule-based steps like exact match for math or confirming code outputs), the system discovers to prefer reasoning that leads to the correct result without the need for specific supervision of every intermediate thought.

DeepSeek R1:

Recognizing that R1-Zero's without supervision technique produced reasoning outputs that could be tough to read or even mix languages, the developers went back to the drawing board. They used the raw outputs from R1-Zero to produce "cold start" information and after that manually curated these examples to filter and enhance the quality of the reasoning. This human post-processing was then utilized to fine-tune the original DeepSeek V3 model further-combining both reasoning-oriented support knowing and monitored fine-tuning. The outcome is DeepSeek R1: a model that now produces readable, coherent, and trusted thinking 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 capabilities without specific supervision of the thinking procedure. It can be further enhanced by utilizing cold-start information and supervised reinforcement finding out to produce understandable reasoning on basic jobs. Here's what sets it apart:

Open Source & Efficiency:

R1 is open source, allowing scientists and designers to check and build on its developments. Its cost efficiency is a significant selling point especially when compared to closed-source models (claimed 90% more affordable than OpenAI) that need massive calculate spending plans.

Novel Training Approach:

Instead of relying entirely on annotated thinking (which is both expensive and time-consuming), the model was trained using an outcome-based technique. It started with quickly verifiable jobs, such as math issues and coding workouts, where the correctness of the last response might be quickly measured.

By utilizing group relative policy optimization, the training process compares multiple created answers to identify which ones meet the desired output. This relative scoring system allows the model to discover "how to think" even when intermediate reasoning is generated in a freestyle manner.

Overthinking?

A fascinating observation is that DeepSeek R1 sometimes "overthinks" simple problems. For example, when asked "What is 1 +1?" it may invest almost 17 seconds assessing different scenarios-even thinking about binary representations-before concluding with the proper response. This self-questioning and verification procedure, although it might seem inefficient in the beginning glimpse, could prove advantageous in complicated tasks where much deeper thinking is necessary.

Prompt Engineering:

Traditional few-shot triggering strategies, which have actually worked well for lots of chat-based models, can actually deteriorate performance with R1. The designers advise utilizing direct problem statements with a zero-shot approach that specifies the output format plainly. This ensures that the design isn't led astray by extraneous examples or tips that may hinder its internal thinking process.
