Active Compute Fabric, spun off from Intel in 2020, targets wasted GPU idle time via an open architecture and is now shipping with a Qualcomm partnership in the works.
OpenAI now requires explicit safety cases before major capability-boosting reinforcement learning runs, and backs a federal safety framework and independent auditors. Pacing progress, he argues, does not mean stopping development.
The researcher clarifies his post-Meta path, framing the roughly $1B startup around world models, planning and inference-by-search — a vision he says he has pushed since 2016.
Building a spatial-goal-conditioned action prior with no images and constraining visual conditioning through a pose-supervised latent interface lifts success across Pi0.5, MolmoAct2 and real-world unseen-camera tests.
Simple Attention Sparsification trains an attention-sparse selector end-to-end inside a Triton FlashAttention kernel, beating trainable sparse-attention baselines on reasoning, long-context and agentic tasks.
A data-centric post-training framework on 164K verified trajectories improves CyberGym by 23.76% with a small open-weight team, placing 10th on the official leaderboard.
Couples contextual-bandit prioritization with evidence-grounded skill evolution, cutting optimization cost 55-58% versus SkillOpt with only 50 examples per benchmark.
Byte-level models trail token-based ones at low compute but surpass them as scale grows, roughly 4% ahead at the ceiling and matching performance with as little as one-sixth the training data.
A calculator estimating payback period of a local LLM rig against API usage, the top Show HN item of the window at 42 points.
A minimal open-source CLI coding agent accepting user-provided API keys, framed as a lighter alternative to heavier frameworks.
An experiment nesting an AI coding agent through three layers of isolation to explore portable, sandboxed local execution.
A control-plane platform for orchestrating and governing an organization's agents, with deployment and policy management.
A motion-graphics editor built around AI-driven animation workflows for generating and refining motion designs interactively.
A Series C led by M Capital plus asset-backed financing from MUFG and Quester backs AI underwriting for cross-border trade finance.
An oversubscribed Series A led by Serendipity Capital funds silicon-rooted cryptographic keys for AI infrastructure security.
A Series A led by BlackFin Capital Partners backs AI-agent financial API connectivity out of Brussels.
Free means $0 per token today, not unlimited or unconditional: both platforms rate-limit free use and require a free API key, some OpenRouter free endpoints may train on your prompts unless you opt out in account settings, and the roster changes daily. Verified against each provider's own pricing data at generation time — but pricing changes without notice, so confirm it's still free on the provider's own page before you rely on it.
