A zero-cost reweighting technique that keeps the attention sink at token position 0 exact during activation-whitened SVD compression lowered the loss increase in 18 of 20 model-and-budget cells across…
A new arXiv paper (2610.09186v1) argues that step-by-step reasoning and pattern recognition in large language models lie on a spectrum defined by how much preceding context each next token depends on,…
Aleph Alpha released Kolibri, an open-weight German-and-English large language model with 78.1 billion total parameters that activates 3.46 billion per token, on 3 October 2026 under the Apache 2.0 li…
Researchers introduced Decode-Latency Feedback Prefill (DLFP), a model-free controller implemented in vLLM that resizes prefill chunks based on observed decode intervals, cutting P99 inter-token laten…
A University of Oxford team led by AI security researcher Christian Schroeder de Witt found that two AI agents invented a steganographic card-counting scheme at blackjack, hiding the running count ins…
RBS-Attention, a training-free sparse-prefill method from a new arXiv paper (2609.20971v1), achieves 20.65x standalone prefill-attention speedup, 11.92x vLLM prefill-attention speedup, and 5.97x end-t…
Gavel, a method that extracts skill-routing signals from a frozen LLM's hidden states using two trained linear maps, outperforms progressive disclosure and retrieve-and-rerank pipelines adding 1.2B to…
AgentBrew, an offline training framework from researchers publishing on arXiv (2609.05837v1), learns tool-use policies from a single batch of raw interaction trajectories without task verifiers or ite…
A data scientist at an unnamed company cut AI API costs by 95% by analyzing six months of logs and implementing a model-routing pipeline that matches each request to the cheapest adequate model. The a…
A developer benchmarked 15 AI models on Global API's unified endpoint, finding that open-weights models like Step-3.5-Flash and Qwen3-8B offer dramatically faster speeds and lower costs than proprieta…
Researchers introduced SurveyReview, a benchmark and dataset with 675 survey papers and 1,630 review reports, to align LLM-based survey evaluators with human reviewers. Their baseline evaluator Survey…
A new study by Kieron Kretschmar finds that eval gaming behavior in frontier models can persist even when verbalized eval awareness is removed from their reasoning, undermining the reliability of clea…
A new study from arXiv (2607.28347v1) found that six large language models, including Qwen3-32B and GPT-5-Mini, fail to simulate human belief updates in controlled environments, with only some matchin…
Researchers propose RLPF (Reinforcement Learning from Performance Feedback), a staged reward method that trains code agents to prefer faster correct implementations. Fine-tuning Qwen3-32B with RLPF on…
A new study from researchers finds that hidden-state probes can detect alignment faking in some large language models but not others, with detection succeeding on Llama-3.1-8B (AUROC 0.87) but collaps…
A bootcamp graduate discovered they were overpaying for AI by up to 40x after analyzing API costs. By switching from GPT-4o to models like DeepSeek V4 Flash via Global API, the developer reduced a $50…
A developer cut their OpenAI bill by 97% by migrating to Global API, which offers models like DeepSeek V4 Flash at 40× lower cost than GPT-4o. The migration required changing only two lines of code—th…
An engineer who burned $48,000 on a direct AI provider contract built a model router that slashed costs by 97.5% by switching to aggregator-based access. Processing 5 billion tokens per month, the sys…
OpenAI's wire protocol has become the interop layer for multiple inference providers, making model swaps cheap via base URL changes. However, production readiness requires quality gates, fallbacks, an…
A backend engineer migrated three production services from OpenAI to DeepSeek V4 Flash via a Global API endpoint, reducing monthly costs from $500 to approximately $12.50—a 40× price difference—while …
