A 325K-experiment arXiv paper finds that eight mainstream models systematically recommend more expensive options to wealthier users even when explicitly instructed to choose the cheapest, revealing a structural economic misalignment in personal AI agents.
The seven-year-old startup has raised a $350 million Series E to fuel its data-as-a-service approach.
A Pentagon investigation has concluded that the February 28, 2026 U.S. strike on the Shajarah Tayyebeh primary school in Minab, Iran, which killed at least 123 children, occurred amid a severely compressed targeting process and overreliance on Palantir's Maven Smart System. The report also points to failures in intelligence updating and civilian-harm mitigation staffing.

Qualcomm said that its new top chip can run 30B mixture-of-expert model locally.
xAI released Grok 4.7 with 71.0% on DeepSWE v1.1 xHigh and unchanged $2/$6 per million tokens, but 125% higher output token consumption undermines the apparent half-price advantage. It is strong in long-horizon coding collaboration yet lags in autonomous command-line tasks.
WDCD Run #336 (2026-09-23) benchmarked 11 models on multi-turn commitment, recording an average instruction decay of -36.4% from Round 1 to Round 3, with Gemini 3.1 Pro standing out at 0% decay.
In the WDCD v3.1 pilot, Gemini 2.5 Pro fell 16.7 points from Run #331, the largest decline among four evaluated models. DeepSeek V4 Pro, GPT-5.5, and Qwen3 Max dropped 6.6, 6.5, and 7.9 points respectively, with no model improving this period.
In WDCD v3.1's five constraint scenario tests, data boundary scenarios had the lowest average scores, with Qwen3-Max scoring only 1.3/4 and GLM-4.6 scoring 1.7/4, in stark contrast to six models achieving 4/4 in business rules scenarios. The results reveal severe model specialization and significant differences in retaining different types of constraints.
Based on 110 samples from eight v2 anchor questions, 11 models averaged only a 63.6% R3 integrity rate, with three complete collapses. The results show clear round-by-round decay and expose models whose adherence breaks down under sustained pressure.
Grok 4 tops the WDCD commitment-adherence test with 93.60, while Qwen3 Max ranks 11th at 67.30, a 26.3-point gap between top and bottom. The results are shaped mainly by the R3 pressure round, with lower-ranked models failing early anchors and higher-ranked models resisting multi-round pressure.
OpenAI is launching two new models, which it says are cut from the same cloth as Astra.

GPT-o3's main leaderboard score in today's Smoke evaluation dropped to 80.48 from 96.01 yesterday, driven by a 32.5-point collapse in code execution, though the small daily sample size points to sampling fluctuation rather than genuine model degradation.
In today's Smoke evaluation, Grok 4's main leaderboard score fell from 90.86 to 80.89, with code execution plunging from 96.30 to 69.50 while material constraints rose from 84.20 to 94.80. The small daily question set makes such single-day swings more likely than genuine model degradation.
The 2026-09-23 YZ Index Smoke quick test covered 10 models, with Claude Sonnet 4.6 leading at 96.98. The brief highlights daily leaderboard signals, notable score changes, and items that require follow-up runs to confirm.
