Ali Qianwen 3 is released and open source, with parameters only one-third of DeepSeek-R1

Alibaba has open-sourced the new generation of Tongyi Qianwen model Qwen3 (Qwen3 for short), which has only 1/3 of the parameters of DeepSeek-R1, and announced that the cost has dropped significantly, and the performance has surpassed leading models such as R1 and OpenAI-o1. Qianwen 3 is a "hybrid reasoning model" that integrates "fast thinking" and "slow thinking" into the same model, greatly saving computing power consumption. It is understood that Qianwen 3 adopts a mixed expert (MoE) architecture, with a total parameter volume of 235B and only 22B required for activation. The pre-training data volume of Qianwen 3 reaches 36T tokens, and after multiple rounds of reinforcement learning in the post-training stage, the non-thinking mode is seamlessly integrated into the thinking model. Qianwen 3 has been greatly enhanced in reasoning, instruction following, tool calling, and multi-language capabilities. While the performance has been greatly improved, the deployment cost of Qianwen 3 has also been greatly reduced. Only 4 H20s are needed to deploy the full-blooded version of Qianwen 3, and the video memory occupancy is only one-third of that of models with similar performance.

OpenAI launches a lightweight version of Deep Research for free

OpenAI said in a statement: Noticing that many users like to use Deep Research, OpenAI has expanded the scope of use for Plus, Team, and Pro users by introducing a lightweight version of Deep Research to increase the current rate limit. We also launched a lightweight version for free users. Powered by OpenAI o4-mini, Deep Research Lite delivers a level of intelligence close to the standard Deep Research that users know and love, while costing significantly less to operate. This version of the response content is generally more concise while maintaining the depth and quality that users expect. When the usage quota of the standard version is exhausted, the system will automatically switch to the lightweight version to respond to queries. All Plus, Team, and Pro users now have extended access to Deep Research. Enterprise and Education users will gain access the following week and will have the same usage levels as Team users. A lite version of Deep Research is rolling out today to all free users.
