Claude Mythos Preview found a new attack on HAWK (quantum-resistant signature scheme) halving its key strength in ~60 hours, and a 200-800x speedup on reduced-round AES attack in a week, at ~$100k compute cost per result. Anthropic released technical papers and the CryptanalysisBench benchmark.
xAI introduced Build Mode, letting users build and customize AI agents directly within the Grok platform, and integrated Grok 4.5 into GitHub Copilot for AI-powered code completions in the IDE.
Cyera, which raised $600M at a $12B valuation, acquired Oasis Security for $1B to expand AI security capabilities as agent deployments surge across enterprises.
Multi-agent frameworks routinely entangle three logically distinct concerns: who is on the team, how members align, and which algorithm fuses their work. IMACS introduces a decoupled taxonomy evaluated across 10 benchmark environments.
A retraction-free optimizer avoids costly orthonormalization during LoRA fine-tuning, achieving 2-3x speedup over standard methods while maintaining convergence quality on LLM tasks.
A multimodal benchmark reveals that even top MLLMs fail at basic grounding tasks (color, shape, counting) while excelling at knowledge transfer — exposing a gap in atomic visual perception.
A policy-adaptive multimodal safety classifier that matches or outperforms models nearly 7x its size on text safety benchmarks and sets a new SOTA on multimodal safety classification.
A linear-time sequence model with sparse memory routing that achieves near-perfect recall on long-range dependency tasks up to 32K tokens, outperforming SSMs and linear Transformers on the Long Range Arena.
Kimi K3 is getting significant attention for its agentic and long-running capabilities. Together AI published a comprehensive usage guide and is hosting an event on July 30 with Moonshot's Feihu Tang for a deep dive on architecture and production inference.
Recent papers discuss distilling from proprietary to open-source models via multi-agent protocol distillation for agentic search, and stateful approaches for long-horizon computer-use agents.
Together AI posted about production inference improvements including capacity-aware routing, rollouts, and autoscaling on dedicated endpoints that benefit open-weights deployments.
The FCC added Chinese humanoid and quadruped robots to its Covered List, barring imports of new units. The ban extends to connected power inverters and targets vulnerabilities in Unitree hardware deployed at MIT, Princeton, and Carnegie Mellon.
AMD signed a deal with Core Scientific to secure up to 2.5 GW of data center capacity across five sites, optimized for AMD Instinct GPUs, EPYC CPUs, and ROCm software.
Tesla's recent earnings revealed major disappointments in its humanoid Optimus business and robotaxi program, with production timelines slipping and investor confidence wavering.
Prefactor offers real-time evaluation of AI agents in production, scoring every run for quality, drift, and risk, then enforcing policies automatically or with human approval.
Cekura provides a testing, observability, and self-improvement platform for production voice and chat AI agents, simulating thousands of scenarios to catch regressions before users do.
Leaping AI, a YC-backed startup, deploys human-like AI voice agents for customer service, lead qualification, and appointment scheduling across calls and SMS.
BrowserAct enables AI agents to browse websites, click buttons, fill forms, solve CAPTCHAs, and extract data via a simple CLI.
Fish Audio raised a $52M seed round led by Coreline Ventures and Capital Today for AI voice models targeting creators and enterprise use cases.
Dwelly raised a $170M Series B ($95M equity) led by EQT Growth and General Catalyst for AI-powered real estate and proptech operations.
Hush Security raised a $30M Series A for AI agent governance and security, with Akamai Technologies joining as a strategic investor.
Codeberg's members voted 358 to 144 to amend their Terms of Use, prohibiting projects that consist primarily of AI-generated code, weeks after prominent developer Theo (t3.gg) urged the community to move to the platform.
Higgsfield is running a promotion giving new users 24 hours of free unlimited access to its top image, video, and audio models including Seedance 2.0, running July 28-31.
