Hard math, especially Olympiad-style problems, is a distinctive test of LLM intelligence. But public math benchmarks increasingly seem saturated. So we dug through physical books (even ones from 1800s) and papers we couldn't find anywhere online and collected a few thousand problems we believe are unseen by today's models. We tested a few popular open-weight LLMs on a sample of these problems, scoring their performance out of 100. Kimi K3 leads, but the result that caught my eye is Qwen 3.8 27B: a 27B model scoring 57.6, ahead of DeepSeek V4 Flash and Gemini 3.7 Flash. How far can smaller models go? #llm #aiformath #posttraining #olympiadmath

When the dust settles, we'll have to talk about the fact that not a single vulnerability was found by a US frontier model. Instead, we're spending $10k a day on open weights models like Kimi K3 and Qwen 3.8 to find vulnerabilities in Bitcoin infrastructure. It's a disaster.

The bitcoin community didn't verify/compare the entropy of generated seeds across different HWWs. But this should become a common test done by reviewers at product release and at all software/firmware update releases. HWW vendors should facilitate these tests.

Shame on those who spent the last 2 years distracting the community with a contrived 'spam emergency' and retarded fork nonsense. Things like covenants/vaults can enhance self-custody security, and these people obstructed their delivery to users. Hope the forkplant was worth it!
MK4s are vulenerable but are millions of times harder to steal from. MK3s can be stolen from a decent laptop, mk4,5s and Q would need much more compute. The model: - attacker has a roughly 2^20 UUID range that it knows cold cards fall in - checks a 16 button press variancer in user behavior before generating the seed You should still promptly remove funds from mk4,mk5 and Q.

Over a thousand bitcoin moved today in an attack. Doing emergency triage to identify the source of the issue this is how it went: @AnthropicAI - Instant Downgrade. @OpenAI - A little help. @Kimi_Moonshot - One shot. The US needs to get it shits together. @DavidSacks
trying to investigate an active security incident. Got blocked by codex. Kimi came through.

I found 2 private keys that were part of the 500 BTC hack, so this is independently confirmed
Confirmed. Mk2/3 vuln, I don't think mk4 is but can't be certain

Many Bitcoiners are upset and beefing with each other. I suspect root cause is the bear market combined with TradFi markets experiencing an AI boom. Folks want a scapegoat for disappointing returns. BTC could have been more interesting but devs were told we had to ossify...

For context, desktop computers were so slow just a 3 decades ago that searching for files was not practical. We are now very near running models that are almost as good as hosted ai locally. Including the multi modals too. Setting this up: # Daily driver — text + vision + coding, 35B MoE / 3B active, ~17GB Q4 # Vision is built-in (no separate VL model needed) ollama pull qwen3.6:35b-a3b # RAG embeddings — exceeds OpenAI, MTEB 70.58, ~5GB Q4 ollama pull qwen3-embedding:8b # Local AI Setup Guide Hardware: M5 Max 128GB MacBook Pro + DGX Spark (optional) ## 1. Install ```bash # Ollama (inference engine) brew install ollama echo 'export OLLAMA_USE_MLX=1' >> ~/.zshrc source ~/.zshrc ollama serve & # Open WebUI (frontend — vision, search, RAG, tools, code execution) docker run -d -p 3000:8080 --name open-webui \ -e OLLAMA_BASE_URL=http://host.docker.internal:11434 \ -v open-webui:/app/backend/data \ ghcr.io/open-webui/open-webu… # SearXNG (private web search) docker run -d -p 8080:8080 --name searxng searxng/searxng ``` Enable JSON output in SearXNG: edit `settings.yml`, add `formats: - json` under `search:`. In Open WebUI Admin → Web Search: enable, set engine to `searxng`, URL to `http://host.docker.internal:8080/search?q=<query>`. ## 2. Pull Models ```bash # Daily driver — text + vision + coding, 35B MoE / 3B active, ~17GB Q4 # Vision is built-in (no separate VL model needed) ollama pull qwen3.6:35b-a3b # RAG embeddings — exceeds OpenAI, MTEB 70.58, ~5GB Q4 ollama pull qwen3-embedding:8b # Tool calling router — tiny, fast, 0.960 agent score ollama pull qwen3:1.7b ``` Optional: ```bash # Dedicated coding model (if you want a separate code-focused model) ollama pull qwen3-coder:30b # Separate vision specialist (if you need deeper image analysis than qwen3.6 provides) ollama pull qwen3-vl:8b ``` ## 3. RAG (document Q&A) Open WebUI has built-in RAG. In Admin → Documents: - Embedding model: `qwen3-embedding:8b` - Chunk size: 1024, overlap: 128 - Upload PDFs/docs directly in chat with `#` prefix For heavy document work, install Marker for PDF parsing: ```bash pip install marker-pdf marker_single input.pdf output/ ``` ## 4.

DGX Spark (if owned) ```bash # Point Open WebUI at Spark's Ollama docker run -d -p 3000:8080 \ -e OLLAMA_BASE_URL=http://SPARK_IP:11434 \ ghcr.io/open-webui/open-webu… # Or use TensorRT-LLM for max performance on Spark # (2.5x faster than Ollama on supported models) ``` Run heavy models on Spark, light models on Mac. Open WebUI can connect to multiple Ollama instances. ## 6. What You Get vs Cloud | Feature | Local | vs GPT/Claude | |---------|-------|:---:| | Chat | Qwen3.6-35B-A3B | 85-90% | | Images | Qwen3-VL-8B | 90-95% (beats GPT-4o on docs) | | Web search | SearXNG | 90% | | Documents | RAG + Marker | 70-80% | | Tool calling | Qwen3 | 90% | | Code exec | Sandbox | 85% | | Privacy | 100% local | — | | Cost after hardware | $0 | — | ## 7. When to Use Cloud Keep Claude Code + Opus 4.6 for: - Complex multi-file refactoring - Hard debugging requiring deep reasoning - Novel architectural decisions - Long multi-turn conversations (200K+ context) Everything else runs locally
Everyday is becomes more obvious hosted Ai will go away like shared and scheduled university computation time.

This is a big deal. Look at these pricing numbers. $25.00 on Claude $3.20 on Morpheus. Morpheus is 87% cheaper than Clause 4.5! For GLM-5 an equivalent open weight model.

This could be an incredible revolution in Cosmology. The Dark Energy model of the universe, which won a Nobel Prize in 2011, may be completely wrong. The accelerating expansion instead is simply because time runs faster in the voids between galaxies. Let me explain:

The Digital euro or CBDC will not fulfill the three main characteristics of money. Because of its proposed limits (3k) it will not function as a proper store of value stlouisfed.org/education/econ…

“invested over a million dollars in developing a finance-domain focused LLM named BloombergGPT within just six months … a model (AdaptLLM-7B) costing merely $100 came out surpassing BloombergGPT in performance.” Tech is brutal lol
Replying to @rasbt
BloombergGPT was great when it came out. But just to put the rapid evolution of LLMs into perspective 📌 Bloomberg invested over a million dollars in developing a finance-domain focused Large Language Model (LLM) named BloombergGPT. And within just six months of the release of BloombergGPT, a model (AdaptLLM-7B) costing merely $100 came out surpassing BloombergGPT in performance. 📌 And now fine-tuning a 7-bn parameter model can be done for less than $100 on AWS and can be completed in 5-7 Hours. 📌 Some may contend that the BloombergGPT was designed using proprietary data. 📌 However, this proprietary data made up a negligible 0.70% of the dataset. And the rest 99.30% of the data originated from public sources accessible to everybody.

This is perhaps one of the most important charts on AI for 2024. It was built by the amazing researcher team at @CathieDWood’s @ARKInvest. We can see the rise of open source local models are on the path to overtake massive (and expensive) cloud based closed models.

LK99, absence of flux pinning explained, a consequence of being a 1D superconductor. (Obvious once pointed out.)
Replying to @ESYudkowsky
The 1D superconductor pathways only reject magnetic fields when flux is perpendicular to their pathways. This property then explains why, despite a strong diamagnetic effect, the rocks won't levitate completely.

First video of LK-99 Full Levitation, aka flux-pinning This video was just posted to the Chinese video-sharing site BiliBili and claims to be a highly pure synthesized sample of LK-99. What is the physical phenomenon behind this and what does it mean? Levitation of superconducting materials is a phenomenon unique to what is called Type-II superconductors, and is an effect whereby magnetic field lines becomes 'trapped' as it passes through the material, providing the force needed to levitate. These are the popular images and videos of cryogenically-cooled discs floating above a magnet frequently seen online and in the pinned post on my profile. You can think of this like strands of hair being caught in gum - the gum is suspended in mid-air by adhering strongly to the hair as the hair passes through it. The hair in this case is magnetic field lines and the gum is the Type-II superconductor. Just like hair comes in individual strands, or in other words hair is 'quantized' or 'discrete', so is the flux trapped at the 'pinning centers' quantized in what are called 'magnetic vortices' - the quantization of pinned flux lines is a key property and distinguishing characteristic of Type-II superconductors (although technically can occur in Type-I superconductors if the material thickness is smaller than the London penetration depth, which is indeed very small - specifics for the physics nerds out there). Flux-pinning is entirely unique to superconductors and is also wholly distinct from the Meissner effect. It is not a property of diamagnets or diamagnetism. At @TRIUMFLab I contributed to flux-pinning studies in Niobium crystal superconducting radio-frequency cavities used for particle acceleration. In that application, trapped flux poses an issue by increasing the remnant surface resistivity of the cavity, which has the effect of decreasing its effective quality factor or Q-factor, which is a measurement of a resonators efficiency. SRF cavities typically have Q-factors of 10E10 and trapped flux at pinning centers reduces the maximum effective accelerating electric field used to drive charged particle bunches close to the speed of light. Flux pinning is thought to arise in some Type-II superconductors by small imperfections in the crystal, also called volume defects, that enable flux to penetrate the material. In SRF cavities an issue that arises is any magnetic field that is passing through the material, e.g. by the Earth's background field, can become pinned or trapped inside the cavity as it transitions into a superconducting state. See some attached plots in the comments from a study showing how the surface resistivity of SRF cavities increases the more there is a background field as the cavity transitions into superconducting state. This is the first video I am aware of that claims to show the flux-pinned levitation of a LK-99 sample. If this is in fact what is happening, then it is a very unique and promising finding of this new materials properties and potential for future study. If this is real then it is truly ground-breaking
