Anthropic, OpenAI, Cloudflare and Google now each ship an AI agent that hunts security bugs in source code. We checked the repos, docs and technical details behind each one. The key finding: all 4 tools converge on one design. One agent finds a bug, a separate agent tries to disprove it, and only survivors get a patch. The differences are in where they run, who can use them and how much proof they demand. Key Takeaways 4 labs, 1 pattern: find, independently disprove, then patch. Claude Security runs inside Claude Code; no extra API key needed. Codex Security’s CLI is Apache-2.0, but scanning still needs OpenAI access. Cloudflare’s skill is MIT, model-agnostic and the most-starred at 47.5K. Google’s Mantis reproduces bugs in a sandbox; Google says isolate it. Why 4 labs shipped the same thing in 2026 The problem every one of them is solving is noise. Google’s security team writes that sloppy AI code scanning produces hallucin...

Samaya AI has released Samaya Sterling , a post-trained model for agentic financial research. Sterling is built on NVIDIA’s Nemotron 3.5 Lightning , a 30B mixture-of-experts model with 3B active parameters. On Samaya’s FrontierFinance benchmark , it scores 58.9%. Claude Fable 5.1 scores 55.9%. Each Sterling question costs $0.61, against $6.89 for Fable 5.1. For developers, the takeaway is a concrete recipe: co-train a small model with its harness, and it can win in a narrow domain. TL;DR Size: 30B total, 3B active (MoE). Base model context: up to 1M tokens. Sterling’s serving context: not disclosed. Runs on: the base model fits a single H100 80GB in BF16 (256K context). Sterling’s serving hardware: not disclosed. Performance: beats every high-quality system on the FrontierFinance leaderboard on quality per dollar (self-reported). Best: 58.9% on FrontierFinance (60.6% in high-effort mode), vs 55.9% for Claude Fable 5.1. Worst: 45.2% ...

Edge0 has released Audio8-TTS-Realistic , an open-weight text-to-speech model for zero-shot voice cloning. Audio8-TTS-Realistic is a 0.6B-parameter model that clones a voice from 1 reference clip and transcript. It supports 23 languages, 12 more than its predecessor. The weights and code ship under Apache 2.0 . For developers, the catch is competitive multilingual accuracy at a size that is cheap to fine-tune and serve. TL;DR Size: 601M main-model parameters (codec excluded); up to 2,048 packed text/audio positions of context. Runs on: a CUDA GPU is recommended; smoke-tested on NVIDIA H20 in BF16. The paper reports 1.1 to 1.2 GiB peak memory on an Apple M2 CPU (INT4 ONNX). No Realistic ONNX export is public yet. Performance: ahead of larger open models on CV3, behind 4B-class models on MiniMax. Best: 4.86% average CV3 error across 9 languages, versus 7.73% for Qwen3-TTS-1.7B. Worst: 48.57% WER on Thai (CV3) and 31.35% CER on Cantonese (MiniMax). What...

Block’s AI research lab has released Dessa , a full-duplex speech model trained only on human conversation. Block announced it on October 23, 2026 as a research preview. Dessa is a speech-to-speech model from Block that listens and talks at the same time. Block says it used no text and no pretrained models. That is a different design from the text-first stacks behind most voice agents today. TL;DR Runs on: A MacBook Pro M4 Max or better, locally, faster than real time. Performance: Demo-only so far. Live recordings show backchannels, mid-sentence laughs and natural interruptions. Best: Trained on 1 NVIDIA GB200 NVL72 rack (72 GPUs). Moshi used 1,016 H100 GPUs. Worst: 0 published benchmark scores. No weights, paper, API or price. What is Block’s Dessa? Dessa is a true speech-to-speech model: audio in, audio out. According to Block’s project page , everything it knows came from human speech. It is full-duplex, so it listens while i...
