Every week, I organize 400 to 700 links into roughly 60 categories as part of my ongoing effort to learn about AI. This is my personal notebook, which I enjoy sharing with friends… a hobby and a labor of love, rather than a commercial publication or product.
If you arrived here through a search or shared link, this page collects the links I found for DeepSeek for the week ending August 21, 2026.
As part of my learning process, I like to automate the category covers. It gives me a chance to learn Python and APIs.
This week’s cover prompt was written using Claude Opus 4.7, and the image was generated using Nano Banana 2.1.
Category Cover Image Prompt: Realistic architectural photograph of a 1930s Shanghai Art Deco limestone skyscraper in bright raking sunlight under a deep blue sky, with a stylized engaged herm at a setback holding a plumb line and a geometric carved whale against its chest, its body narrowing into the pier below, surrounded by dark steel-framed windows and receding neighboring buildings. The honey-cream Indiana limestone wall beneath the figure bears a large incised Art Deco inscription reading DEEPSEEK in classical capitals, flanked by chevron waves, perspective-corrected verticals, no other text.
This Week in DeepSeek News
Summary by Claude Sonnet 5.5 based on this week’s links:
- The harness goes open source: DeepSeek open-sourced DeepSeek Harness (dsh) on Aug 13, the same day V4 Pro shipped. Turing Post describes it as the layer that turns a model into an agent, covering tools, memory, sandbox and scheduling, with everything built as a plugin.
- V4 Pro pricing and serving: Zhihu Frontier noted that API pricing moved to peak and off-peak rates when V4 Pro launched. LMSYS also published a post on pushing the limits of serving DeepSeek-V4-Pro.
- Local models catching up: Cline cited the Artificial Analysis index placing Qwen3.8-27B at DeepSeek V4-Pro level. Ollama pointed to its performance with DeepSeek V4 Flash and offered Qwen3.8 as the local-only option.
This summary was generated by Claude Sonnet 5.5 to help you explore the links below. Rest assured, I select, organize, and check the links by hand in Google Sheets, and write the introduction and personal commentary in The Main Newsletters myself each week as a labor of love.

Ollama has the best performance for deepseek v4 flash on average. For local only, you can try qwen3.8 that is optimized: Apple Silicon: ollama run qwen3.8:27b-mlx NVIDIA: ollama run qwen3.8:27b”

Artificial Analysis Intelligence Index puts Qwen3.8-27B at DeepSeek V4-Pro and GPT 5.6 Luna performance. This is the first time a local model has scored frontier model capability. We weren’t expecting this pace of local progress anywhere near this soon.”

Qwen 27B is the “DeepSeek moment” for open source. It matches the closed-source state-of-the-art from just a few months ago and runs on an RTX 5090. Without exaggeration, it’s a game changer.”
