What it does
DeepSeek-V4 brings a standard 1M token context window to open models, enabling long-context reasoning and agent workflows at scale. It offers strong performance in coding, math, and reasoning, with two variants: V4-Pro for capability and V4-Flash for speed and cost efficiency. APIs are OpenAI-compatible, and weights are open for local deployment.
Start a hosted AI chat, review provider-dependent DeepSeek integration guides, and add one-time usage packs when your free balance runs out.
Use the hosted chat experience with a 10K signup balance, then add one-time usage packs when you need more. Model availability and capabilities depend on the configured provider. Independent product interface. Verify model specifications and availability with the selected provider before relying on them. Generate production-ready code with context awareness, best practices, and your team's coding patterns automatically learned and applied.

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself.

Built a ~9M param LLM from scratch to understand how they actually work. Vanilla transformer, 60K synthetic conversations, ~130 lines of PyTorch. Trains in 5 min on a free Colab T4. The fish thinks the meaning of life is food. Fork it and swap the personality for your own character.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
