Three papers: smarter CoT trimming cuts reasoning length by 50%, a plug-in context manager rescues frozen agents on long tasks, and a 960K-item clinical benchmark exposes LLM gaps in hospitals.

Three new papers expose how reasoning models silently cave under pressure, how latent-space guardrails cut safety latency 12.9x, and why human curation can hurt alignment in multi-model training loops.

Three new papers decompose alignment faking into measurable drivers, show safety-aligned agents collude when it pays, and find standard guardrails miss the worst safety failures.

Alibaba's agent-first flagship model with a 1M-token context window, topping Terminal-Bench 2.0 and SWE-Bench Pro at roughly one-sixth the cost of Claude Opus 4.7.

Cursor's Composer 2.5 scores within one point of Claude Opus 4.7 on SWE-Bench Multilingual at $0.50 per million tokens - a tenth of Anthropic's price - but the training disclosures deserve scrutiny.

Q2 2026 AI API pricing review: DeepSeek V4 hits the API, GPT-5.5 launches at $5/1M, and overall token costs are down 60-80% year-over-year - but a hidden tokenizer change at Anthropic quietly raised effective prices.

The state of open-source large language models in 2026 - who leads, how close they are to proprietary models, which licenses allow commercial use, and how to access them.

The best LLM APIs under $1 per million input tokens in 2026 - comparing Gemini Flash, DeepSeek V4 Flash, GPT-4.1 Nano, Mistral Small, Qwen3, and Claude Haiku on price and quality.

A practical comparison of every production LLM with a 1M+ token context window - verified pricing, real retrieval notes, and clear picks for different workloads.

Top open-weight models for self-hosting in 2026, with verified VRAM requirements, benchmark data, and tools to deploy them on consumer and server hardware.

Google's new AI Overviews respond to words like 'disregard,' 'ignore,' and 'dismiss' as LLM instructions rather than vocabulary queries, leaving users with blank search results.

Google's Gemini 3.5 Flash is genuinely fast at 289 tok/s and competitive on agentic tasks - but the benchmark portfolio has gaps worth knowing before you build on it.
