We have actually been tracking the explosive increase of DeepSeek R1, setiathome.berkeley.edu which has taken the AI world by storm in recent weeks. In this session, we dove deep into the development of the DeepSeek family - from the early models through DeepSeek V3 to the breakthrough R1. We also checked out the technical developments 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 design; it's a family 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 specialists are utilized at inference, considerably enhancing the processing time for each token. It also featured multi-head hidden attention to decrease memory footprint.

DeepSeek V3:

This design introduced FP8 training techniques, which assisted drive down training expenses by over 42.5% compared to previous iterations. FP8 is a less precise method to keep weights inside the LLMs but can considerably enhance the memory footprint. However, training utilizing FP8 can typically be unstable, and it is difficult to obtain the preferred training results. Nevertheless, DeepSeek utilizes multiple techniques and attains remarkably steady FP8 training. V3 set the stage as a highly efficient design that was currently affordable (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 iteration. Here, the focus was on teaching the design not simply to produce answers but to "believe" before addressing. Using pure support knowing, the model was motivated to generate intermediate thinking steps, for instance, taking extra time (frequently 17+ seconds) to overcome an easy problem like "1 +1."

The key development here was the usage of group relative policy optimization (GROP). Instead of relying on a standard process reward design (which would have needed annotating every step of the reasoning), GROP compares multiple outputs from the design. By sampling several prospective responses and scoring them (utilizing rule-based steps like specific match for math or confirming code outputs), the system finds out to favor reasoning that leads to the right outcome without the need for it-viking.ch explicit guidance of every intermediate idea.

DeepSeek R1:

Recognizing that R1-Zero's not being watched technique produced reasoning outputs that might be difficult to check out or perhaps blend languages, the designers went back to the drawing board. They used the raw outputs from R1-Zero to create "cold start" data and after that by hand curated these examples to filter and enhance the quality of the reasoning. This human post-processing was then utilized to tweak the initial DeepSeek V3 model further-combining both reasoning-oriented reinforcement learning and monitored fine-tuning. The result is DeepSeek R1: a model that now produces legible, meaningful, and reliable reasoning while still maintaining the effectiveness 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 further enhanced by utilizing cold-start information and monitored reinforcement finding out to produce understandable reasoning on general tasks. Here's what sets it apart:

Open Source & Efficiency:

R1 is open source, allowing researchers and designers to examine and build on its innovations. Its cost effectiveness is a significant selling point specifically when compared to closed-source models (claimed 90% less expensive than OpenAI) that require huge calculate budgets.

Novel Training Approach:

Instead of relying solely on annotated thinking (which is both pricey and lengthy), the model was trained utilizing an outcome-based technique. It began with quickly verifiable tasks, such as mathematics problems and coding exercises, where the accuracy of the last response could be quickly determined.

By utilizing group relative policy optimization, the training procedure compares multiple created answers to figure out which ones meet the desired output. This relative scoring system allows the model to learn "how to believe" even when intermediate thinking is produced in a freestyle way.

Overthinking?

A fascinating observation is that DeepSeek R1 sometimes "overthinks" simple problems. For instance, when asked "What is 1 +1?" it may invest almost 17 seconds various scenarios-even considering binary representations-before concluding with the proper response. This self-questioning and verification process, although it might appear inefficient at very first glance, might show helpful in complicated tasks where deeper thinking is essential.

Prompt Engineering:

Traditional few-shot prompting methods, which have actually worked well for many chat-based models, can in fact deteriorate performance with R1. The designers recommend using direct problem statements with a zero-shot approach that specifies the output format plainly. This ensures that the model isn't led astray by extraneous examples or tips that might hinder its internal thinking process.

Q&A

Q1: Which model is worthy of more attention - DeepSeek or Qwen2.5 Max?

A: While Qwen2.5 is likewise a strong model in the open-source community, the choice eventually depends on your usage case. DeepSeek R1 stresses advanced thinking and an unique training technique that might be specifically important in tasks where proven reasoning is vital.

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