WTF! I want my money back. I upgraded my plan to Max 20x just so I could use Fable 5 for next 12 days. "The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance." www.anthropic.com/news/fable-m...

Anthropic's When AI builds itself "We looked at sessions where a human researcher took a wrong turn, showed Claude the session up to that point, and asked it what to do next. Mythos Preview improved on humans 64% of the time—up from 22% in 2024." www.anthropic.com/institute/re...

OpenAI wants to teach machines to love humanity. I want humans protected from powerful AI. I also want an answer to what humans owe the minds they're growing. "Love" is a strange word to use without asking that. https://openai.com/index/an-alien-mind/
AI Weekly's analysis

- OpenAI chief scientist Jakub Pachocki published 'An Alien Mind' on September 6, arguing modern AI has become an intelligence humans do not fully understand.
- He wrote that no lab has solved alignment and monitoring well enough to keep scaling at maximum speed for much longer.
- Pachocki called for voluntary slowdowns until shared safety bars are set, and for international coordination to become a top government priority.

- Anthropic launched Claude Opus 5 on July 24, 2026 at $5 per million input tokens, matching Opus 4.8's rate.
- On Frontier-Bench v0.1 Opus 5 scored 43.3%, versus 18.7% for Opus 4.8 and 33.7% for Fable 5.
- Opus 5 becomes the default on Claude Max but sits behind Mythos 5 on cybersecurity tasks, per Anthropic.

Mathematics in the age of AI by Terence Tao An essay on how the mathematical community might respond to the arrival of AI tools that are capable of performing research-level mathematical tasks. arxiv.org/abs/2608.16753
AI Weekly's analysis
→
- Terence Tao's ICM 2026 essay sidesteps the debate over AI's math capability and focuses on how results are verified, communicated and digested by the community.
- In the First Proof evaluation Tao cites, seven of ten novel problems got at least one passing grade from an AI system, at tens to hundreds of dollars each.
- Tao would block publication if authors cannot give a clear, expert-level talk on their own AI-assisted result, and requires disclosure of any tool use.

New gemma!!! And it's a diffusion model! Deepmind keeps releasing diffusion stuff 🤔 it's not that much worse on benches compared to the same sized autoregressive Gemma 4
AI Weekly's analysis
→
- DiffusionGemma generates 256 tokens per forward pass using bidirectional attention, reaching 1,000+ tokens/sec on a single H100 GPU.
- With only 3.8B active parameters during inference and an 18GB VRAM footprint when quantized, it runs on consumer hardware without server-grade resources.
- Google recommends DiffusionGemma only for speed-critical workloads like in-line editing and code infilling, not for applications requiring maximum quality.

"LLM hallucinations in the wild: Large-scale evidence from non-existent citations" Paper: arxiv.org/abs/2605.07723
AI Weekly's analysis
→
- Researchers audited 111 million references across 2.5 million papers on arXiv, bioRxiv, SSRN, and PubMed Central to find non-existent citations at scale.
- They estimate 146,932 hallucinated citations in 2025 alone, concentrated in fields with rapid AI uptake and in small or early-career author teams.
- Fake citations disproportionately credit already prominent and male scholars, and existing preprint moderation catches only a fraction, the paper says.

When building an agentic AI app, - you do not need memory, - you do not need a router, - you do not need an orchestrator, All you need is a message board!
When you are the most profitable company in the world, this happens: NVIDIA reportedly priced the deal at $12.9303 billion as a nerdy joke: The “129303” part is the decimal version of U+1F917. U+1F917 is the Unicode code for the 🤗 hugging-face emoji. Hugging Face uses 🤗 as its signature emoji.

They discovered that reasoning models produce fractals when asked to solve hard problems. You can use nonlinear dynamics to probe the thinking processes of recurrent depth models on Sudoku, mathematics, and even ARC-AGI
The big story is Chinese AI chips. By restricting GPU exports to China, we effectively handed Chinese chipmakers a captive market. GLM-5.3-Flash - Natively multimodal with a 1M-token context window - A 320B-A18B model released under the MIT License - Running entirely on Chinese AI chips

Just a reminder that this phase of generative AI, called agentic AI, is only 9 months old. Yes, we're early.
Shots fired at Anthropic. Interesting...
DeepSeek-V4.1-Flash 🔹 552B-parameter MoE. 🔹 New Causal Encoder–Decoder architecture: just 8B active parameters for input, 16B for output. 🔹 New pre-training methods + larger-scale RL post-training deliver benchmark results ahead of flagship models, including DeepSeek-V4-Pro.
