NEW: Anthropic is walking back Claude Fable 5's policy to covertly degrade performance for competing AI researchers, after facing fierce backlash.
“We’re changing Fable 5’s safeguards for frontier LLM development to make them visible,” Anthropic tells WIRED. “We made the wrong tradeoff and we apologize for not getting the balance right.”
🚨 BREAKING: Google considering banning search queries that could reveal how search engines work, as users might otherwise attempt to build alternatives to Google Search that don't have advertisements, which could "endanger ad revenue" and "lead to societal collapse".

can't lie, Mythos 5 is a damn good model though
GPT-5.5 was the most *thorough* model i had ever used
Mythos 5 is even more thorough; it seems like a true next-gen model
this week is the first time I've had Claude Pro (1 week trial tho), or have used modern Claude
while my requests erroneously keep getting downgraded from Fable 5 to Opus 4.8, it seems Opus 4.8 is actually better than GPT-5.5 on more than a few tech related tasks relevant to me
absolutely insane that Claude Mythos will sabotage any of your projects that Anthropic disagrees with by intentionally giving you wrong advice, writing code with subtle errors you're likely to miss, etc
it starts with requests suspected to be LLM development, but what next?
BREAKING NEWS: Anthropic's latest model will NOT help you if it thinks your ML research/ML engineering is interesting, and/or will secretly degrade its IQ so that the average engineer won't notice. We are already seeing Anthropic's latest model's moderation filters our GPU inference research and programming 😭
@nicdunz I installed it on my iPhone 12 mini, it's a direct upgrade so far, other than autofilling credentials from my password manager (Proton) sometimes causes an app to stop accepting input
as a workaround, after the app freezes, you have to switch to another app and back
from limited testing (less than a day) with Opus 4.8, it seems Opus has more ML knowledge than GPT-5.5: 4.8 is aware of even niche papers and their details that GPT-5.5 isn't
🚀 1,000+ TOKENS/S ON A 1T MODEL! 🚀
We are thrilled to release Xiaomi MiMo-V2.5-Pro-UltraSpeed in collaboration with @TileRT_AI , breaking the 1,000 tokens/s output speed on a 1 Trillion parameter model for the FIRST TIME!
Not wafer-scale integration like Cerebras. Not pure on-chip SRAM chips like Groq. We achieve 1,000 tps on a 1T MoE model using just a SINGLE, STANDARD 8-GPGPU NODE.

if Claude Mythos comes to Claude Pro, "hello" will probably exhaust the plan's usage limits for the entire month before Mythos even finishes generating a completion
