Anthropic said it had not advocated banning open-weight models and argued that less capable releases were a public good. It instead supported tighter chip controls, action against industrial-scale distillation, and mandatory safety testing for sufficiently capable open and closed models.

Moonshot has released the model weights for Kimi K3, along with a technical report. Kimi K3 is a 2.8T Mixture-of-Experts model with native visual understanding. It has a 1-million-token context window and a new model architecture that gives it 2.5x the intelligence per unit of compute. Alongside Kimi K3, Moonshot is opening up more of the stack behind it — high-performance attention kernels, a MoE communication library, and infrastructure for running agent environments at scale.

<strong>DeepsecBench: evaluating model performance in finding cybersecurity vulnerabilities (6 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
DeepsecBench is a benchmark that evaluates how well different models find cybersecurity vulnerabilities in application code. The report includes recall, precision, cost, and total time for each model and combines recall and precision into a single benchmark score. DeepsecBench runs on an open-source codebase at a commit state just before a large number of vulnerabilities were fixed. The construction of the benchmark is secret so models aren't able to train against it.

KimiK3's gains come from more than scaling: it combines constant-state Kimi Delta Attention, periodic softmax retrieval, sparse experts, and selective residual access. Each architectural step improves how fixed-capacity memory stores, forgets, and retrieves information while preserving efficient inference.

Ramp Labs has open-sourced PorTAL, a framework for shared task representations and cross-model LoRA adaptation. PorTAL learns a base-agnostic task latent and a light per-base alignment that generates ordinary per-layer LoRA weights. A task can be trained once, adapted to supported frozen base models, and exported as a standard Hugging Face PEFT adapter.

<strong>Gemini Distillation Service (17 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
The Gemini Distillation Service allows users to train a smaller, more efficient 'student' model that uses the outputs and reasoning patterns of a larger, more capable 'teacher' model. Distillation enables production-grade efficiency while allowing smaller models to achieve a deeper level of reasoning. It is recommended for high-volume, latency-sensitive applications, complex reasoning tasks, and when there are significant performance gaps between the teacher and student models. The distillation service currently only supports gemini-3.1-pro as the teacher model and gemini-2.5-flash as the student model.

<strong>How we built and benchmarked VR-1, our frontier cyber reasoning model (6 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Cogent VR-1 can autonomously investigate environments, test hypotheses, cross system boundaries, and execute attack chains. IntrusionBench is a benchmark for measuring whether cyber agents can complete realistic enterprise attack chains from limited starting access. On the black-box configuration of IntrusionBench, VR-1 achieved more than a 2x lift in pass@3 over the strongest frontier baseline. VR-1 and IntrusionBench are both at an early preview stage, so the results are preliminary.

<strong>How much can you delegate to agents? (7 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Agent autonomy depends on task complexity, not just model quality. Tasks fall into four levels: assistant, human-in-the-loop, agent delegation, and self-driving, determined by ease of checking and potential consequences of errors. Implementing guardrails, custom skills, and domain-specific models enhances agent autonomy and efficiency.
