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 family - from the early designs through DeepSeek V3 to the development R1. We also explored the technical developments that make R1 so unique worldwide of open-source AI.

The DeepSeek Ancestral Tree: From V3 to R1

DeepSeek isn't just a single design; it's a household of significantly advanced 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 lower memory footprint.

DeepSeek V3:

This design presented FP8 training techniques, which assisted drive down training expenses by over 42.5% compared to previous iterations. FP8 is a less precise method to save weights inside the LLMs however can considerably enhance the memory footprint. However, training using FP8 can generally be unsteady, and it is difficult to obtain the preferred training outcomes. Nevertheless, DeepSeek utilizes multiple techniques and attains extremely stable FP8 training. V3 set the stage as a highly efficient model that was already affordable (with claims of being 90% more affordable than some closed-source alternatives).

DeepSeek R1-Zero:

With V3 as the base, the team then presented R1-Zero, the very first reasoning-focused model. Here, the focus was on teaching the design not just to create responses but to "think" before addressing. Using pure support knowing, the model was motivated to generate intermediate reasoning steps, for example, taking extra time (typically 17+ seconds) to overcome a simple issue like "1 +1."

The crucial innovation here was the usage of group relative policy optimization (GROP). Instead of depending on a conventional process reward design (which would have required annotating every step of the reasoning), GROP compares numerous outputs from the model. By tasting a number of possible answers and scoring them (utilizing rule-based steps like precise match for math or confirming code outputs), the system learns to favor thinking that leads to the correct result without the requirement for specific guidance of every intermediate thought.

DeepSeek R1:

Recognizing that R1-Zero's without supervision approach produced thinking outputs that might be hard to read or perhaps blend languages, the designers returned to the drawing board. They utilized the raw outputs from R1-Zero to create "cold start" data and then manually curated these examples to filter and enhance the quality of the reasoning. This human post-processing was then used to tweak the original DeepSeek V3 design further-combining both reasoning-oriented reinforcement learning and supervised fine-tuning. The outcome is DeepSeek R1: a model that now produces legible, coherent, and trusted thinking while still maintaining the effectiveness and cost-effectiveness of its predecessors.

What Makes R1 Series Special?

The most remarkable aspect of R1 (absolutely no) is how it established thinking abilities without specific guidance of the reasoning process. It can be further improved by using cold-start information and supervised support discovering to produce legible thinking on basic tasks. Here's what sets it apart:

Open Source & Efficiency:

R1 is open source, enabling researchers and designers to inspect and build on its developments. Its cost efficiency is a significant selling point particularly when compared to closed-source models (claimed 90% cheaper than OpenAI) that require massive compute budgets.

Novel Training Approach:

Instead of relying entirely on annotated reasoning (which is both costly and lengthy), the model was trained using an outcome-based technique. It began with quickly verifiable tasks, such as mathematics problems and coding workouts, where the accuracy of the final response might be easily determined.

By utilizing group relative policy optimization, the training process compares multiple produced answers to figure out which ones meet the wanted output. This relative scoring mechanism permits the design to find out "how to believe" even when intermediate thinking is created in a freestyle manner.

Overthinking?

An interesting observation is that DeepSeek R1 sometimes "overthinks" easy problems. For instance, when asked "What is 1 +1?" it might spend nearly 17 seconds examining various scenarios-even considering binary representations-before concluding with the proper answer. This self-questioning and verification process, although it might appear ineffective in the beginning look, could prove helpful in complicated jobs where deeper reasoning is necessary.

Prompt Engineering:

Traditional few-shot triggering techniques, which have worked well for many chat-based models, can actually degrade efficiency with R1. The designers suggest using direct issue declarations with a zero-shot approach that specifies the output format plainly. This ensures that the model isn't led astray by extraneous examples or hints that may interfere with its internal thinking procedure.

A: Early models like R1-Zero did produce raw and often hard-to-read reasoning. However, the subsequent improvement process-where human professionals curated and enhanced the thinking data-has significantly enhanced the clearness and dependability of DeepSeek R1's internal idea procedure. While it remains an evolving system, iterative training and feedback have caused meaningful enhancements.

Q17: Which design versions appropriate for regional release on a laptop with 32GB of RAM?

A: For local testing, a medium-sized model-typically in the series of 7B to 8B parameters-is recommended. Larger models (for example, those with numerous billions of parameters) need substantially more computational resources and are much better matched for cloud-based deployment.

Q18: Is DeepSeek R1 "open source" or does it use only open weights?

A: DeepSeek R1 is provided with open weights, implying that its model specifications are publicly available. This lines up with the total open-source viewpoint, permitting scientists and designers to more explore and build on its developments.

Q19: What would happen if the order of training were reversed-starting with supervised fine-tuning before not being watched reinforcement knowing?
