Understanding DeepSeek R1
We have actually been tracking the explosive rise of DeepSeek R1, which has taken the AI world by storm in current weeks. In this session, we dove deep into the evolution 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 worldwide of open-source AI.
The DeepSeek Ancestral Tree: From V3 to R1
DeepSeek isn't just a single design; it's a family of progressively sophisticated AI systems. The evolution goes something like this:
DeepSeek V2:
This was the foundation model which leveraged a mixture-of-experts architecture, where just a subset of professionals are used at inference, dramatically improving the processing time for each token. It also included multi-head latent attention to minimize memory footprint.
DeepSeek V3:
This design presented FP8 training methods, which assisted drive down training costs by over 42.5% compared to previous models. FP8 is a less precise way to keep weights inside the LLMs however can significantly enhance the memory footprint. However, training using FP8 can typically be unsteady, and it is hard to obtain the desired training outcomes. Nevertheless, DeepSeek utilizes multiple tricks and attains extremely stable FP8 training. V3 set the phase as an extremely efficient model that was currently cost-effective (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 version. Here, the focus was on teaching the design not simply to generate responses but to "think" before answering. Using pure support knowing, the design was motivated to generate intermediate reasoning steps, for instance, taking extra time (often 17+ seconds) to overcome a simple issue like "1 +1."
The key innovation here was the use of group relative policy optimization (GROP). Instead of depending on a conventional process benefit model (which would have needed annotating every step of the thinking), GROP compares multiple outputs from the design. By sampling several possible responses and scoring them (utilizing rule-based procedures like exact match for mathematics or validating code outputs), the system learns to prefer reasoning that causes the proper result without the need for specific supervision of every intermediate thought.
DeepSeek R1:
Recognizing that R1-Zero's not being watched approach produced thinking outputs that could be difficult to read and even blend languages, the developers returned to the drawing board. They utilized the raw outputs from R1-Zero to generate "cold start" information and then manually curated these examples to filter and enhance the quality of the thinking. This human post-processing was then utilized to fine-tune the initial DeepSeek V3 design further-combining both reasoning-oriented reinforcement learning and supervised fine-tuning. The outcome is DeepSeek R1: a model that now produces readable, coherent, and dependable reasoning while still maintaining the effectiveness and cost-effectiveness of its predecessors.
What Makes R1 Series Special?
The most remarkable aspect of R1 (no) is how it established thinking capabilities without specific guidance of the reasoning process. It can be further enhanced by utilizing cold-start data and supervised support learning to produce readable thinking on basic tasks. Here's what sets it apart:
Open Source & Efficiency:
R1 is open source, permitting researchers and developers to inspect and build upon its innovations. Its expense performance is a major selling point specifically when compared to closed-source designs (claimed 90% less expensive than OpenAI) that require huge compute budgets.
Novel Training Approach:
Instead of relying solely on annotated thinking (which is both pricey and time-consuming), the model was trained using an outcome-based method. It started with quickly verifiable jobs, such as math issues and coding exercises, where the accuracy of the final response could be quickly measured.
By utilizing group relative policy optimization, the training process compares several generated responses to identify which ones meet the desired output. This relative scoring system allows the model to learn "how to think" even when intermediate reasoning is produced in a freestyle manner.
Overthinking?
An interesting observation is that DeepSeek R1 often "overthinks" easy problems. For instance, when asked "What is 1 +1?" it might invest almost 17 seconds examining different scenarios-even considering binary representations-before concluding with the appropriate answer. This self-questioning and confirmation process, although it might seem inefficient initially glimpse, could prove useful in intricate jobs where much deeper reasoning is needed.
Prompt Engineering:
Traditional few-shot triggering techniques, which have actually worked well for lots of chat-based designs, can in fact degrade performance with R1. The designers suggest using direct problem statements with a zero-shot approach that defines the output format plainly. This guarantees that the model isn't led astray by extraneous examples or hints that may interfere with its internal reasoning procedure.
