ng agent requests suggests humans in the loop aren't as good at spotting dangerous commands as one might hope, with players approving roughly one in three malicious requests on average. The results also suggest that repeatedly having to approve an agent's actions can lead to sloppy decisions. It’s a quick, simple game on the surface (give it a try - you know you want to): A small window shows up on the screen with simulated permissions requests like one would get from Claude Code as it executes

6 If training with LoRA isn't producing the results you were expecting, the adapter itself may not be the problem. We did controlled experiments on Qwen3.5-9B showing how data coverage, optimization, and rank can create or close the quality gap to Full Parameter Fine-Tuning, or FullFT. Which lever moved?

Rather than reinventing each check, wire in maintained open-source tools: The dependency scan is the highest-leverage step because it targets a failure mode unique to code models, now commonly called slopsquatting. The model invents a plausible-looking package name, an attacker registers that name in a public registry, and the hallucinated dependency ships real malware to anyone who installs the suggestion.

n-source project create one. Putting two competing outcomes in one /goal prompt results in uneven optimization. We ran into this repeatedly when a goal asked for both bugs and coverage. When we put “find bugs” and “achieve high coverage” in the same prompt, the run ended up doing one of them far better than the other. This was our experience while using /goal to audit zlib. Codex kept gravitating to the same part of the codebase, fuzzing the areas the model found first without reaching the rest.

Streaming means the system starts playing audio before the full response has been generated.

uld give particularly strong guidance that might not always be true. For example, in the system prompt we used to say: In code: default to writing no comments. Never write multi-paragraph docstrings or multi-line comment blocks — one short line max. Don't create planning, decision, or analysis documents unless the user asks for them — work from conversation context, not intermediate files. But for a certain subset of prompts, this guidance would be wrong. In the case of documentation, the user m

ing reward during the RLVR stage. So instead of just rewarding the model based on answer correctness, one would provide additional reward for the use of tokens, which in turn encourages the model to use those. In DeepSeek-R1, for example, the overall reward was calculated as R total = R accuracy + R format where the format reward was a simple rule-based check that encouraged the model to place its reasoning inside: reasoning trace .

earning how the world looks: the visual concepts, the objects and scenes, how things are composed and lit, and the sheer range of what images can contain. That is a problem of coverage and diversity, not of per-image perfection. A broad, representative corpus teaches the model far more about the structure of the visual world than a smaller, prettier one would, even if many of the individual images are ordinary snapshots or slightly compressed. Over-filtering for aesthetics at this stage would ac

hand-holding. /goal forced the objective to live across multiple turns and compactions so the model held scope, and 5.5-Cyber was smart enough to reject weak findings, expand coverage when a line of investigation died, and keep running until it had workable proof-of-concepts backed by sanitizer output. Over the next several hours, it built the campaign out one piece at a time: Each of these decisions is routine on its own, but stringing them together in the right order across a dozen entrypoint

It probably has a much higher token usage. So, below, I additionally looked at the token usage of all three harnesses. As we can see, Claude Code uses by far the most tokens on average, Codex the least. When it comes to the little agent capability assessment benchmark, the Qwen and North Mini Code models also get 5/5, and even the small Gemma 4 model does ok! Interestingly, we can also see that the token usage is largely driven by the harness, not the LLM itself. I.e., among all three LLMs that

During decode, we first build a page table based on the selected blocks, flatten the KV-group dimension into the batch dimension, and leverage the strided view of a KV cache tensor to provide the attention kernel with the pointer needed to retrieve the KV page. The trick is the stride: page addresses advance by D to choose a virtual page start, while tokens advance by Hkv D. That deinterleaves one physical tensor into per-head pages, so each flattened ro
