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 advancement of the DeepSeek household - from the early designs through DeepSeek V3 to the development R1. We also checked out the technical innovations that make R1 so unique on the planet of open-source AI.

The DeepSeek Ancestral Tree: From V3 to R1

DeepSeek isn't just a single design; it's a household of increasingly advanced AI systems. The advancement 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 improving the processing time for each token. It also featured multi-head hidden attention to minimize memory footprint.

DeepSeek V3:

This design presented FP8 training techniques, which helped drive down training expenses by over 42.5% compared to previous versions. FP8 is a less exact way to keep weights inside the LLMs however can significantly enhance the memory footprint. However, training utilizing FP8 can usually be unstable, and it is tough to obtain the wanted training results. Nevertheless, DeepSeek uses numerous tricks and attains incredibly stable FP8 training. V3 set the phase as an extremely effective model that was currently cost-efficient (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 very first reasoning-focused model. Here, the focus was on teaching the design not simply to produce responses but to "think" before addressing. Using pure reinforcement learning, the model was motivated to produce intermediate thinking steps, for setiathome.berkeley.edu example, taking additional time (often 17+ seconds) to resolve a basic problem like "1 +1."

The key innovation here was the usage of group relative policy optimization (GROP). Instead of relying on a standard procedure reward model (which would have required annotating every action of the reasoning), GROP compares multiple outputs from the design. By sampling numerous potential answers and scoring them (utilizing rule-based procedures like precise match for mathematics or validating code outputs), the system finds out to favor thinking that causes the right outcome without the need for explicit supervision of every intermediate idea.

DeepSeek R1:

Recognizing that R1-Zero's unsupervised approach produced reasoning outputs that could be difficult to read or even blend languages, the designers went back to the drawing board. They used the raw outputs from R1-Zero to produce "cold start" data and then manually curated these examples to filter and improve 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 knowing and supervised fine-tuning. The outcome is DeepSeek R1: a design that now produces readable, meaningful, and reliable thinking while still maintaining the efficiency and cost-effectiveness of its predecessors.

What Makes R1 Series Special?

The most fascinating element of R1 (no) is how it developed thinking abilities without specific supervision of the reasoning procedure. It can be further improved by utilizing cold-start data and supervised reinforcement finding out to produce legible reasoning on basic jobs. Here's what sets it apart:

Open Source & Efficiency:

R1 is open source, enabling scientists and developers to examine and develop upon its developments. Its expense performance is a major selling point especially when compared to closed-source models (claimed 90% more affordable than OpenAI) that require massive calculate budgets.

Novel Training Approach:

Instead of relying entirely on annotated thinking (which is both costly and lengthy), the design was trained using an outcome-based method. It started with quickly proven jobs, such as math problems and coding workouts, where the correctness of the last response could be quickly measured.

By using group relative policy optimization, the training process compares several created to identify which ones satisfy the preferred output. This relative scoring system allows the design to find out "how to think" even when intermediate reasoning is created in a freestyle way.

Overthinking?

An interesting observation is that DeepSeek R1 in some cases "overthinks" easy issues. For instance, when asked "What is 1 +1?" it might invest nearly 17 seconds assessing various scenarios-even thinking about binary representations-before concluding with the correct response. This self-questioning and confirmation process, although it might seem inefficient initially glimpse, might show useful in complex tasks where much deeper reasoning is required.

Prompt Engineering:

Traditional few-shot prompting techniques, which have worked well for lots of chat-based models, can actually deteriorate efficiency with R1. The designers advise using direct issue declarations with a zero-shot method that defines the output format plainly. This makes sure that the design isn't led astray by extraneous examples or tips that may interfere with its internal reasoning procedure.
