Prompt Injection: The Unsolvable Problem at LLM Core
By
–
Model vendors been trying and failing to fix it for over three years now The core problem is that prompt injection is an attack against instruction following – and the whole point of LLMs is to follow instructions! At this point I'm not sure what a solution would even look like

Building Persistent Memory for Coding Agents Between Sessions
By
–
Coding agents have a major limitation: they forget everything between sessions. Without memory, they can’t retain project context, past fixes, or key decisions. What they need is a persistent memory layer to store and recall context. Let’s see how to set that up.

Give Coding Agents Long-Term Memory with One Line
By
–
You can now make Claude Code, Gemini CLI, and other coding agents 10x more powerful by giving them long‑term memory! It just takes a single line of code. Here’s a step‑by‑step breakdown (100% local):

Smart Mode on Copilot rolling out with GPT-5
By
–
The time has come! Some users started receiving Smart Mode on Copilot. Earlier, GPT-5 was spotted as powering Smart Mode internally. Considering the earlier announcements, the router part of it could be rolling out already. * I don't have it yet, screenshot is for reference

Iterative LLM Reflections Outperform Heavy Reinforcement Learning
By
–
Iterative reflections for LLMs can outperform heavy RL? This paper shows that having the LLM reflects on its own trajectories, rewrite its own prompts, and evolve a diverse pool of candidates beats RL w/ GRPO so far on four reasoning tasks . 10% improv with 35x fewer rollouts!

Extracting AI System Prompts: Study Mode Verification Methods

I was able to get back the exact same system prompt for study mode across several different attempts, which makes me confident that it's real, not hallucinated I've done this a lot in the past – here's confirmation I got the GitHub Spark one right: https://
