DeepSeek's Open Source Stack

**DeepSeek's Open Source Week** was summarized by PySpur, highlighting multiple interesting releases. The **Qwen QwQ-32B model** was fine-tuned into **START**, excelling in PhD-level science QA and math benchmarks. **Character-3**, an omnimodal AI video generation model by Hedra Labs and Together AI, enables realistic animated content creation. **Google DeepMind** introduced the **Gemini embedding model** with an 8k context window, ranking #1 on MMTEB, alongside the **Gemini 2.0 Code Executor** supporting Python libraries and auto-fix features. **Inception Labs' Mercury Coder** is a diffusion-based code generation model offering faster token processing. **OpenAI** released **GPT-4.5**, their largest model yet but with less reasoning ability than some competitors. **AI21 Labs** launched **Jamba Mini 1.6**, noted for superior output speed compared to Gemini 2.0 Flash, GPT-4o mini, and Mistral Small 3. A new dataset of 1.9M scanned pages was released for OCR benchmarking, with **Mistral OCR** showing competitive but not top-tier document parsing performance compared to LLM/LVM-powered methods. *"Cracked engineers are all you need."*
