With the rapid development of artificial intelligence technology, developers and research institutions face many challenges, including high computing costs, latency issues and the lack of truly flexible open source models. These problems not only limit technological advancements, but also make it difficult for many existing solutions to be promoted in practical applications. Especially in scenarios where efficient computing and low latency are required, existing models tend to rely on expensive cloud infrastructure or are unable to run on local devices because of their size. Therefore, the market urgently needs a new model that can operate efficiently and be flexible.
To cope with this demand, Reka AI launched Reka Flash3, an inference model built from scratch with 2.1 billion parameters. The design goal of this model is to support a variety of application scenarios, including general conversations, coding assistance, instruction follow-up, and function calls. The training process of Reka Flash3 combines public datasets and synthetic datasets, and reinforcement learning is performed through careful instruction tuning and REINFORCE Leave One-Out (RLOO) method. This training method ensures that the model strikes a balance between capability and efficiency, making it stand out among many similar models.
On the technical level, Reka Flash3 has several innovative features that make it outstanding in flexibility and resource efficiency. First, the model is able to handle context lengths of up to 32k tokens, which makes it easy to handle longer documents and complex tasks without overloading the system. Second, Reka Flash3 introduces a “budget mandatory” mechanism, through a specific <reasoning> tag, users can limit the thinking process steps of the model, thereby maintaining consistent performance without increasing computational overhead. Additionally, the model is ideal for deployment on devices, with a full accuracy size of 39GB (fp16), which can be further compressed to 11GB with 4-bit quantization. This flexibility makes Reka Flash3 more fluid when deployed locally, giving it an advantage over larger and resource-intensive models.
Judging from the evaluation metrics and performance data, Reka Flash3 performs well in practical applications. For example, although it scored 65.0 in the MMLU-Pro test and performed moderately, its competitiveness cannot be underestimated after combining with additional knowledge sources such as web search. In addition, Reka Flash3 also performed well in multilingual capabilities, scoring 83.2 on the WMT'23 COMET test, showing its reasonable support for non-English input, although it focuses primarily on English. These results, coupled with their number of efficient parameters relative to their peers such as QwQ-32B, further highlight their potential in practical applications.
To sum up, Reka Flash3 represents a more accessible AI solution. Through a clever balance between performance and efficiency, the model provides a robust and flexible option for general chat, coding and instruction tasks. Its compact design, enhanced 32k token context window and innovative budget mandatory mechanism make it a practical option for device deployment and low-latency applications. Reka Flash3 undoubtedly provides an exciting foundation for researchers and developers looking for both competent and manageable models.
