EVERYONE SAID AI ADS WOULD NEVER WIN AT CANNES Two of them just did. Both built with @Kling_ai. This is more than a new trophy. It proves that AI-driven creativity has now fully matured 🧵↓

#ChatGPT cannot scrape the web and has limited knowledge of the world after 2021. Introducing `WebChatGPT`, a mighty Chrome extension that augments your prompts with relevant results from the web! 🤯 See my demo video below 👇 and install it here: 🔗 chrome.google.com/webstore/detai…

If you’re still sending raw JSON into your LLMs, you’re burning tokens, latency, and budget! Try TOON (Token-Oriented Object Notation). Clear like YAML, compact like CSV: • 30–60% fewer tokens • Up to 50% lower costs • Shines for tabular data. Free and Open source 🧵↓

Microsoft just killed the GPU mafia! 🤯 They've open-sourced bitnet.cpp, a blazing-fast 1-bit LLM inference framework optimized for CPUs. This is a major step forward for running large models locally, without expensive GPUs or cloud costs. Demo app + repo + paper in 🧵 ↓

Everyone is talking about #ChatGPT and #GPT3, but did you know there was a free, #opensource version of GPT-3 called OPT-175B? No login, no credit card needed! ;) 👉 opt.alpa.ai

This is moving way too fast! @OpenAI has just announced a new set of plugins for uploading and processing video clips! 🤯 And just like that, they made so many SaaS obsolete!
