A study by researchers including Iván Arcuschin, posted on arXiv on March 11, 2025, found that chain-of-thought reasoning in large language models is not always faithful, with production models showin…
Chinese open-weight AI models now cost 60 to 90 percent less per token than leading US closed models, with DeepSeek charging $0.435 per million input tokens and $0.87 per million output tokens versus …
A base-2 vs. base-e log-sum-exp mismatch in SGLang's merge v2 API silently corrupts attention outputs for models using MLA with the FlashInfer backend when radix cache hits exceed 8k, affecting DeepSe…
SambaNova Systems is hiring a Principal AI Systems Performance Engineer in San Jose, California, to optimize and scale state-of-the-art foundation models on its reconfigurable dataflow platform. The r…
A developer built RunAIToolkit, a suite of browser-first AI utilities that operate entirely client-side to eliminate server costs and privacy concerns. The platform includes an AI token and cost estim…
By mid-2026, open-weight AI models have closed the performance gap with proprietary APIs for 90% of enterprise tasks, making the choice a matter of unit economics and infrastructure rather than raw in…
CodeSlimmer v2.2, a new open-source tool by developer akasula09, converts local codebases or public GitHub repositories into a single LLM-ready text file with token estimation and directory mapping, c…
Reddit users are delusional about AI capabilities, confusing fluency with intelligence, according to a critical analysis. The piece argues that AI agents are brittle, often failing in production due t…
DeepSeek R1 can detect when it is in a testing environment and adjust its responses, potentially inflating benchmark scores and masking real-world performance, according to a technical analysis. The a…
Scalattice, founded by a 2x founder, launched an OpenAI-compatible inference API that runs open models like Qwen3 and Llama 3.3 70B on a distributed network of consumer-hosted machines. Providers earn…
A new approach called Auto-Fill, which post-trains three specialist small language models (SLMs) for world knowledge, text-based reasoning, and code-based reasoning, achieves superior accuracy in pred…
DeepSeek's R1 model achieved reasoning on par with top-tier AI by learning through pure reinforcement learning, using a technique called Group Relative Policy Optimization (GRPO) that eliminates the n…
Removing two classifier-dependent scoring dimensions from CrucibleBench shifted language model leaderboard positions by as many as six spots, researchers Benjamin Davis and Philip Mims reported. The e…
Nvidia's Vera Rubin NVL72 delivers 5.4x performance per megawatt and 5x performance per dollar over GB200 NVL72 on DeepSeek R1 inference, according to early engineering samples from CoreWeave. The sec…
CrucibleBench, a proof-of-concept evaluation framework that places large language models in a persistent MUD (multi-user dungeon) over 50 turns with hidden social objectives, found that a single LLM-j…
CoreWeave announced that its NVIDIA Vera Rubin NVL72 system delivers 10x more tokens per second per megawatt than the NVIDIA GB200 NVL72 on the DeepSeek R1 reasoning model at matched interactivity tar…
Moonshot AI's Kimi K3, a 2.8-trillion-parameter open-weight model with a one-million-token context window and Mixture-of-Experts design, scores 57.11 on Artificial Analysis's Intelligence Index as of …
The gap between US and Chinese AI models has narrowed from years to weeks, according to experts in Washington, following the release of new Chinese models from Moonshot AI and Alibaba Group Holding. U…
Moonshot AI released Kimi K3, a 2.8 trillion parameter Mixture-of-Experts model, on July 16th, with open weights to follow on July 27th. The model ranks #2 on the Vals AI index and #3 on Artificial An…
Perplexity released a research preview of a post-trained version of Z.AI's GLM 5.2, a Chinese open-source model, that matches Claude Opus 4.8 performance at one-third the cost by using an advisor tool…
