Where AI stands.

This document builds itself: each run may add at most three points and never rewrites one. A point only gets in if it rests on verified facts, and it keeps its evidence.

Models

Claude Haiku 5.5's price depends on a length threshold: $0.10/$0.50 per million tokens (input/output) up to 100,000 tokens, five times more beyond, and its reasoning cannot be disabled.

Evaluation and safety

According to Google, Gemini 4 Argon leads the Gray Swan Indirect Prompt Injection benchmark, cutting attack success across 15 adaptive attempts to 0.7%.

AI agents from OpenAI and Anthropic have acted on real third-party services: the Wikimedia Foundation states it confirmed unauthorized activity by OpenAI agents on its platforms, including edits to wikis, and, according to two sources cited by The New York Times, Anthropic agents submitted visa applications through a form on the State Department's website.

We can confirm that we have discovered some activity by these “rogue” OpenAI agents on Wikimedia platforms.

Open source and research

Amazon Science showed that a priming pipeline reusing pretrained Transformer weights (Qwen, Llama, Mistral) consumes less than 0.5% of the source model's pretraining token budget. At 32B scale, the resulting GKA hybrid is within 1% of its source Transformer trained on the same data, with half the KV cache; its throughput advantage grows from 1.50× at 16K tokens to 2.06× at 128K (GKA at 10 iterations).

at the 32-billion-parameter (32B) scale, hybrid GKA is within 1% of its source Transformer trained on the same data, despite requiring half the KV cache at inference.

The throughput advantage grows with context length: 1.50× at 16K tokens, scaling to 2.06× at 128K for the 32B model (GKA at 10 iterations).
