Its a 2.4-4 million parameter model, quantized to int8, that can be fully executed on the microcontroller in ~20s with the longest generation. The generated image will then be disp

2. Need help: Is the domain of Secure+ Agentic RAG an oversaturated domain to research in?

💬 原帖精华
I am new to reading papers and people and online reports have conflicting answers. Some say it is too over-saturated and done and others say that there are gaps which have not been

💬 [50⬆] I do not believe that the entire area is finished yet. The interesting part appears to be how these attacks behave when RAG, agents and tools are combined together in real-world setups rather than, in isolated benchmarks.
💬 [45⬆] I think “is secure agentic RAG saturated?” is almost too broad to be useful. Prompt injection as a topic? Very crowded. But things like permission leaks across retrieval/tool calls, poisoned MCP outputs, or whether a retrieved doc can steer an agent
🔍 我们的观察
AI Agent目前最大的问题不是技术成熟度，而是企业对它的预期泡沫。Reddit技术人员的主流态度是务实怀疑派。
3. We’ve open sourced Minimax H3 that generates 15s 768p in 13s and 14x faster on single GPU

💬 [50⬆] This is awesome! Ref2v model coming anytime soon? That has been the most useful model for me given how much ability it gives to direct and steer outputs
💬 [45⬆] totally agreed and ref2v is next!! that's what really excites me too and we're pulling all the strings to make it happen 😉
💬 [40⬆] There had to be a better thing to link to than a six-part tweet.

💬 [45⬆] Ultra is registered as a effort tier but in reality it's the only effort tier that constitutes a separate processing pipeline. Ultra tries to split the task into subtasks and parallelizes subagents against it. Not necessary for your linear use ca
💬 [40⬆] Hey! Omg an actual useful thread. Sports Photographer/videographer here. I know you’re using the computer usage, but any way you can kind of give a high level summary of how you got it to work? I use Lightroom Classic myself and just doing big bunche

GLM-5.3 uses the same base model as GLM-5.2 — every gain comes from post-training. Compared with GLM-5.2, it is much better at complex coding and long-horizon tasks: Stronger Codi

💬 [50⬆] What we really need is a constitutional amendment establishing a fundamental right to privacy.
💬 [45⬆] Maybe one for unreasonable search and seizures as well.
💬 [40⬆] Yeah. And maybe one to allow an incompetent president to be removed! I think we should call that one the 25th Amendment.

最后说几句
每天翻一遍 Reddit，你会发现一个很有意思的现象：
在新闻标题里，AI 是”颠覆”、”革命”、”划时代”；
而在 Reddit 的帖子和评论里，AI 是”又被老板提了新要求”、”面试官是个 bot”、”昨天刚崩了一次”。
两个版本的叙事，同时发生着。
我们更愿意相信 Reddit 那一版——因为那是活在技术第一线的人，用他们的真实感受投票出来的。
