Tesla's AI5 processor taped out at Samsung Foundry using a 2nm-class process, featuring a 384-bit GDDR6/GDDR7 memory interface for use in cars, robots, and data centers.
Helsing closed a $1.8 billion Series E led by Dragoneer Investment Group with Lightspeed, General Catalyst, Accel, and Plural, cementing its position in the AI defense sector.
PixVerse closed a $439 million Series C extension led by CDH Investments with Alibaba, Lollapalooza Capital, and Ivy Capital, fueling the AI video generation and world models space.
Uses a pre-trained video generative diffusion backbone as a feed-forward perception model. Achieves SOTA on depth, surface normal, camera pose, and 3D keypoint prediction with 7-500x less training data than prior methods.
Introduces 46 long-horizon terminal tasks with dense reward grading. The strongest frontier model achieves just 15.2% pass@1, with agents consuming avg 9.9M tokens per task.
Combines UCB1-based tree search with a 3-layer world model, achieving 100% success on synthetic planning tasks with zero LLM calls during inference vs 37 for LATS.
PTQ framework introducing gradient covariance into quantization. At 2-bit weight-only on LLaMA-3-70B achieves 7.93 perplexity while GPTQ and GPTAQ diverge.
Reveals PPO-Clip's Euclidean metric flaw and proposes isometric updates on the Riemannian manifold. Achieves up to 60% improvement over GRPO on AIME24 across seven benchmarks.
Theo exposes a design issue in GPT 5.6's Ultra mode: what appears as a reasoning level actually spawns max-reasoning sub-agents on repeat, consuming the five-hour usage limit in as little as 20 minutes per run.
OpenAI discontinued the standalone Codex application, folding its functionality into ChatGPT. The Codex app now redirects to ChatGPT, marking the end of Codex as a separate product for AI-powered coding.
Semantic SQL inspector that checks queries against schema facts before execution. Runs ~0.1 ms per check fully offline, Apache-2.0. Found 45 real bugs in Spider and BIRD with zero false positives.
Lets AI agents search nearly 10,000 real websites by fonts, colors, components, and layouts. Runs locally through MCP with a Chrome extension to save design references.
Runs real integration flows for AI agents building API integrations. Over 1,600 MCP installs. Catches duplicate events, stale state, and race conditions before production.
Plugin connecting Claude Code, Codex, OpenClaw, and MCP agents to live external data — search, web scraping, social media, finance — through a single account with auto-failover.
Series A led by NEA with SV Angel and Bain Capital Ventures for a sovereign AI and cloud security platform.
Nous Research is reportedly in talks for at least $75M in Series B funding led by Robot Ventures with USV, targeting a $1.5B valuation for the open-source AI agent company.
