o3-mini is now in Langtail 🚀

Deepseek R1 is now part of Langtail and it's so good for reasoning 💪

🚀 Just added DeepSeek-V3 to Langtail! This beast was trained on ~15T tokens and really shines at coding and following instructions. Impressive how it keeps up with (and often beats) the big closed-source models. Try it out in Langtail 💅

💎 Vercel's AI package is such a gem for LLM APIs. Super clean abstraction + that useChat hook for frontend is *chef's kiss* Langtail has first-class support for it - use our saved prompts while keeping all the flexibility to override anything. Just works™️

🧠 Just added OpenAI's new o1 models to Langtail! These models actually think before they answer, using internal reasoning chains to tackle complex problems.

🎮 Built a quick demo tool to show off Gemini 2.0 Flash's object detection Drop an image, hit detect, and get precise bounding boxes. Super clean JSON output too. Try it yourself (link in the comment). Built with @langtail

🔥 Just added Gemini 2.0 Flash (Experimental) to Langtail! First model we've tested that actually nails object bounds detection in images. No more guessing - this thing is precise. Been testing it extensively and honestly, we're impressed.

📚 Just published: "The Wild World of LLM APIs: Where AI Meets Reality" Want to know what you can actually build with AI APIs? We've put together a comprehensive guide covering 9 different categories and 40+ practical use cases - from content creation to developer tools. Check it out here: langtail.com/blog/what-can-…

🤔 Want to master prompt engineering? Think of it like clear communication! Key takeaways: • Keep prompts focused - one task at a time • Write like you're talking to a human • Test & iterate your prompts • Use AI tools to improve results Check out the full guide: langtail.com/blog/what-is-t…

Who still writes AI prompts by hand? 🤔 Watch as I show you something that might change your mind. Think of it like having a prompt engineering expert sitting next to you, but available 24/7. You tell it what you need, it asks smart questions, and crafts the perfect prompt. But here's the cool part: You can immediately test how strong your prompt is. It's like a sparring match - if your prompt has proper guardrails, it wins. If not, the system helps you fix it. No more guesswork. No more trial and error. Just reliable, battle-tested prompts in minutes. Want to see it in action? Check out the link in the comments 👇
