We have actually been tracking the explosive rise 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 breakthrough R1. We also explored the technical innovations that make R1 so special 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 significantly advanced AI systems. The advancement goes something like this:

DeepSeek V2:

This was the foundation model which leveraged a mixture-of-experts architecture, where just a subset of specialists are used at inference, considerably improving the processing time for each token. It also featured multi-head latent attention to minimize memory footprint.

DeepSeek V3:

This model introduced FP8 training methods, which assisted drive down training costs by over 42.5% compared to previous models. FP8 is a less exact method to save weights inside the LLMs however can greatly improve the memory footprint. However, training using FP8 can normally be unsteady, and it is hard to obtain the desired training results. Nevertheless, DeepSeek utilizes numerous tricks and attains incredibly stable FP8 training. V3 set the stage as a highly effective model that was already economical (with claims of being 90% more affordable than some closed-source alternatives).

DeepSeek R1-Zero:

With V3 as the base, the group then presented R1-Zero, the very first reasoning-focused version. Here, the focus was on teaching the design not just to generate answers however to "think" before responding to. Using pure reinforcement learning, the design was encouraged to produce intermediate thinking actions, for instance, taking additional time (typically 17+ seconds) to resolve an easy problem like "1 +1."

The essential innovation here was using group relative policy optimization (GROP). Instead of depending on a traditional procedure reward model (which would have needed annotating every step of the reasoning), GROP compares multiple outputs from the model. By tasting numerous possible answers and scoring them (utilizing rule-based procedures like exact match for mathematics or confirming code outputs), the system discovers to favor thinking that leads to the proper outcome without the need for explicit supervision of every intermediate idea.

DeepSeek R1:

Recognizing that R1-Zero's not being watched approach produced reasoning outputs that could be difficult to read or perhaps mix languages, the developers went back to the drawing board. They utilized the raw outputs from R1-Zero to create "cold start" information and then manually curated these examples to filter and improve the quality of the thinking. This human post-processing was then utilized to tweak the original DeepSeek V3 model further-combining both reasoning-oriented support learning and monitored 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 aspect of R1 (absolutely no) is how it developed reasoning abilities without explicit guidance of the reasoning procedure. It can be further improved by utilizing cold-start data and supervised support discovering to produce readable thinking on general tasks. Here's what sets it apart:

Open Source & Efficiency:

R1 is open source, allowing scientists and designers to examine and build on its developments. Its cost performance is a major selling point especially when compared to closed-source models (claimed 90% less expensive than OpenAI) that compute spending plans.

Novel Training Approach:

Instead of relying entirely on annotated thinking (which is both costly and time-consuming), the design was trained utilizing an outcome-based approach. It began with quickly verifiable tasks, such as math issues and coding workouts, where the accuracy of the final response could be easily determined.

By using group relative policy optimization, the training process compares multiple created answers to determine which ones satisfy the wanted output. This relative scoring mechanism permits the design to learn "how to believe" even when intermediate reasoning is generated in a freestyle manner.

Overthinking?

An interesting observation is that DeepSeek R1 sometimes "overthinks" easy problems. For example, when asked "What is 1 +1?" it may spend almost 17 seconds evaluating various scenarios-even considering binary representations-before concluding with the correct answer. This self-questioning and confirmation process, although it might appear ineffective initially look, might show useful in complex jobs where much deeper thinking is necessary.

Prompt Engineering:

Traditional few-shot triggering methods, which have actually worked well for many chat-based models, can in fact break down performance with R1. The developers recommend utilizing direct problem declarations with a zero-shot technique that specifies the output format plainly. This ensures that the model isn't led astray by extraneous examples or hints that might disrupt its internal thinking procedure.
