We have actually 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 advancement of the DeepSeek household - from the early designs through DeepSeek V3 to the development R1. We also explored the technical developments 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 design; it's a family 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 experts are used at inference, drastically enhancing the processing time for each token. It also included multi-head hidden attention to lower memory footprint.

DeepSeek V3:

This design presented FP8 training strategies, which helped drive down training costs by over 42.5% compared to previous iterations. FP8 is a less precise method to keep weights inside the LLMs but can significantly improve the memory footprint. However, training using FP8 can typically be unstable, and it is tough to obtain the wanted training results. Nevertheless, DeepSeek uses several tricks and attains remarkably stable FP8 training. V3 set the stage as an extremely efficient model that was already cost-efficient (with claims of being 90% cheaper than some closed-source options).

DeepSeek R1-Zero:

With V3 as the base, the group then presented R1-Zero, the very first reasoning-focused model. Here, the focus was on teaching the model not simply to create responses however to "think" before answering. Using pure support learning, the design was motivated to produce intermediate thinking actions, for example, taking additional time (often 17+ seconds) to overcome an easy issue like "1 +1."

The essential innovation here was the use of group relative policy optimization (GROP). Instead of counting on a traditional procedure reward model (which would have required annotating every step of the thinking), GROP compares numerous outputs from the model. By sampling numerous potential responses and scoring them (utilizing rule-based steps like exact match for math or confirming code outputs), the system finds out to prefer thinking that causes the appropriate result without the need for explicit guidance of every intermediate idea.

DeepSeek R1:

Recognizing that R1-Zero's unsupervised method produced thinking outputs that might be hard to check out and even blend languages, the designers went back to the drawing board. They utilized the raw outputs from R1-Zero to produce "cold start" information and then by hand curated these examples to filter and enhance 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 is DeepSeek R1: a design that now produces legible, coherent, and trusted reasoning while still maintaining the efficiency and cost-effectiveness of its predecessors.

What Makes R1 Series Special?

The most fascinating aspect of R1 (zero) is how it established thinking capabilities without explicit guidance of the thinking procedure. It can be even more improved by utilizing cold-start data and monitored reinforcement learning to produce readable thinking on general jobs. Here's what sets it apart:

Open Source & Efficiency:

R1 is open source, allowing scientists and designers to inspect and build on its developments. Its cost effectiveness is a significant selling point particularly when compared to closed-source designs (claimed 90% cheaper than OpenAI) that require massive calculate budget plans.

Novel Training Approach:

Instead of relying entirely on annotated thinking (which is both costly and lengthy), the model was trained utilizing an outcome-based approach. It started with quickly verifiable jobs, such as math problems and coding workouts, where the accuracy of the final answer could be easily determined.

By using group relative policy optimization, the training process compares several produced responses to determine which ones meet the wanted output. This relative scoring system permits the design to learn "how to believe" even when intermediate reasoning is created in a freestyle manner.

Overthinking?

An intriguing observation is that DeepSeek R1 in some cases "overthinks" basic problems. For instance, when asked "What is 1 +1?" it may invest almost 17 seconds assessing various scenarios-even thinking about binary representations-before concluding with the right answer. This self-questioning and confirmation procedure, although it may seem inefficient in the beginning glimpse, might prove useful in intricate tasks where deeper reasoning is essential.

Prompt Engineering:

Traditional few-shot prompting strategies, which have worked well for lots of chat-based models, can really deteriorate efficiency with R1. The developers recommend utilizing direct problem declarations with a zero-shot technique that specifies the output format plainly. This makes sure that the model isn't led astray by extraneous examples or hints that might disrupt its internal reasoning process.

Q&A

Q1: Which design should have more attention - DeepSeek or Qwen2.5 Max?

A: While Qwen2.5 is likewise a strong design in the open-source community, the option ultimately depends on your usage case. DeepSeek R1 highlights sophisticated thinking and an unique training method that might be particularly important in tasks where verifiable reasoning is critical.

Q2: Why did major companies like OpenAI choose supervised fine-tuning rather than support learning (RL) like DeepSeek?
