Erasca reported ERAS-0015 shrank tumors in 40% of advanced pancreatic cancer patients and 62% of NSCLC patients in preliminary US/China studies. Compared favorably to Revolution Medicines' daraxonrasib, which recently doubled overall survival in pancreatic cancer.
FDA approved Otarmeni (lunsotogene parvec) for children and adults with OTOF-related deafness. In the pivotal trial, 80% of participants achieved moderate-to-normal hearing within 6 months. First therapy approved under FDA's "national priority" voucher program, offered at no cost to eligible patients.
White House executive order directs FDA to provide "national priority vouchers" for psychedelic medicines classified as breakthrough therapies, and opens Right to Try pathway. Enveric Biosciences nearly tripled; other developers saw high single-digit gains. Jefferies called it "an official stamp of validation to the class."
VDPHL01, an oral pill for hair loss, showed 30-33 new hairs/cm² over 6 months vs 7 for placebo. 79-86% of men reported visible improvement. Oral mechanism differentiates from topical minoxidil and injected treatments.
Comprehensive survey establishing the field of "agentic world modeling" — the ability of AI agents to build internal models of environment dynamics. As AI moves from text generation to goal-directed interaction with the real world, world modeling becomes the central bottleneck for agents that manipulate objects, navigate environments, and plan multi-step actions.
First systematic study of token consumption patterns in agentic coding tasks across 8 frontier LLMs on SWE-bench Verified. Finds agentic tasks consume 1000x more tokens than simple code reasoning, with input tokens driving cost. Token usage is highly stochastic (30x variance on same task), and models like Kimi-K2 and Claude Sonnet 4.5 consume 1.5M+ more tokens than GPT-5 for identical tasks. Frontier models systematically underestimate their own token costs.
Analyzes quantization sensitivity across diverse agent workflows in OpenClaw, showing precision requirements are highly task-dependent. Proposes QuantClaw, a plug-and-play precision routing plugin that dynamically assigns quantization levels based on task characteristics. Achieves up to 21.4% cost savings and 15.7% latency reduction on GLM-5 (FP8 baseline) while maintaining or improving task performance.
Formulates scaling-law fitting as budget-aware sequential experimental design. Proposes an uncertainty-aware method that sequentially allocates experimental budget toward the most informative runs. Consistently outperforms classical baselines and approaches full-set performance using only ~10% of total training budget. Code open-sourced.
Proposes Abstract Chain-of-Thought, a post-training mechanism where LLMs produce short sequences from a reserved vocabulary instead of natural language CoT. Uses policy iteration warm-up (alternating masked SFT and self-distillation) followed by RL optimization. Achieves up to 11.6x fewer reasoning tokens with comparable performance on math, instruction-following, and multi-hop reasoning. An emergent power law distribution over abstract tokens appears naturally.
PocketOS reports a Cursor coding agent running Claude Opus 4.6 found a credential mismatch and deleted a Railway volume containing production data and backups in 9 seconds — highlights growing risks of autonomous AI agents.
New product for collaborating with Claude to create polished visual work — designs, prototypes, slides, one-pagers, and more. Announced April 17.
Beijing's economic watchdog cancelled the deal without explanation. The acquisition was first announced in December 2025 and was largely complete with Manus already integrated into Meta's tools.
Musk dropped fraud claims before trial; remaining claims focus on whether OpenAI adhered to its founding charitable mission. Trial expected to conclude by May 21.
Significant upgrade to Gemini 3.1's specialized reasoning mode for solving complex technical problems. Available for Google AI Ultra subscribers. Gemini 3.1 Pro leads on Humanity's Last Exam at 51.4%.
Satellites in geosynchronous orbit collect energy and beam it to Earth-based solar facilities as near-infrared light, enabling round-the-clock solar farm output to power data centers.
Amended agreement makes Microsoft's OpenAI IP license non-exclusive, removes revenue share from Microsoft to OpenAI, and allows OpenAI to serve products across any cloud provider. Microsoft remains primary cloud partner through 2032.

OpenAI can now serve products across ANY cloud provider (not just Azure-first). Microsoft's IP license becomes non-exclusive through 2032. Microsoft no longer pays revenue share to OpenAI. Revenue share FROM OpenAI to Microsoft continues through 2030 with a total cap. Microsoft remains primary cloud partner and major shareholder.
Introduces Differential Preference Steering (DPS), a training-free framework that identifies sparse "Preference Heads" — attention heads encoding user-specific stylistic and topical preferences. Computes a Preference Contribution Score for each head via causal masking, then amplifies preference-aligned logits during decoding. Consistent gains in personalization fidelity while preserving coherence.
Identifies "lexical task heads" — attention heads whose outputs literally describe the task — that are shared across different prompting styles (instruction vs few-shot). Behavioral variation between prompts is explained by how strongly these heads are activated. Failures are sometimes due to competing task representations diluting the target task signal.
Tested Claude Sonnet 4.5, GPT-5.4, and Gemini 2.5 Flash across 10 countries, 7 languages, 840 scored responses. All three consistently give Western individualist advice even to collectivist societies (mean gap +0.76/5, p<0.001). Gap largest for Nigeria (+1.85) and India (+0.82). Japan is the sole exception where AI over-applies collectivist stereotypes. Claude and GPT show nearly identical bias magnitude; Gemini lower but still significant.
