Open Source LLM Overview: From Llama to Mistral and Qwen
A new timeline charts the development of open-weights models such as Llama, Mistral, and Qwen, published on July 26, 2026. It provides an overview of key milestones and architectures to understand the landscape of large language models with open weights.
What happened?
An article published on July 26, 2026, titled "Open-Weights LLM Release History and Timeline", compiles the development of large language models (LLMs) with open weights. This timeline covers five central model families: Meta Llama, Mistral AI, Alibaba Qwen, DeepSeek, and OpenAI gpt-oss. Additional reference points include Google's Gemma and Microsoft's Phi models.
Key facts
Why it matters
The significance lies in consolidating scattered information about open-source LLMs into a single, verifiable source. Previously, information has been fragmented across various blogs and model cards. By focusing on "durable facts" such as release dates, model generations, architectures, and licences, the article establishes a foundation for understanding industry progress.
Who is affected?
The article is primarily aimed at AI developers, researchers, and AI enthusiasts navigating the complex landscape of open-source LLMs. Companies using or considering the implementation of these models are directly affected by the transparency surrounding licences and architectures.
What else you should know
Each entry in the timeline links to an official first-party source to ensure high reliability. The article avoids pricing details and benchmark results to focus on more enduring technical facts.
