LLM Benchmark: Frontier models now statistically indistinguishablehttps://news.ycombinator.com/item?id=46336990TL;DR: Claude Opus 4.5, Grok 4.1, and Gemini 3 scored within 2.4% of each other (96-98%). All refused to hallucinate and resisted every adversarial attack. Choose your LLM based on price and ecosystem, not benchmarks.## The ExperimentI was tired of synthetic benchmarks like MMLU and HumanEval—they measure something, but not what I actually care about when using an LLM daily. So I built TRIATHLON-LLM: 50 questions across 10 cognitive dimensions including logic puzzles with tricky wording, real math problems (Bayes, combinatorics), code debugging and system design, science explanations with constraints, causal reasoning, language nuance, creativity under constraints, applied ethics, hallucination traps, and adversarial prompts. Tested December 20, 2025.## Results| Model | Score || Gemini 3 | 123/125 (98.4%) || Claude Opus 4.5 | 120/125 (96.0%) || Grok 4.1 | 120/125 (96.0%) |Range: just 3 points (2.4%).On 7/10 categories, all three scored identically—perfect parity on mathematics, code & Dec 20, 2025 3:49 PM

Ask HN: Morning gravy train discussing AI, here is my opinionhttps://news.ycombinator.com/item?id=46334780As great as a nicely formed prompt to a llm and its output may be, how much actual productivity are we talking compared with an experienced internet stackoverflow searcher with multitudes of completed projects in their experienced completed code archive to search on how to they did things, or perhaps those thing once known as books. Suddenly we go from the 3x to 4x to 1.5x to 2x factoring in prompt creation time and its tweaking, for ok to great llm output. It's not that llm code is lengthy, its that an expert, one that is professional must know the code to almost the point of memorization to at least total understanding of it.Dec 20, 2025 9:30 AM

MyRobot, a Venture Capital Pitchhttps://news.ycombinator.com/item?id=46333852Wrap yourself in a personal robot called Ava (homage to Ex Machina).A perfect morning coffee is waiting as you wake up. The house robot brings it to you as you awake.Suppose you want to get breakfast at a restaurant. The car shows up. You get driven to the restaurant. As you get seated your order arrives. Ava knows that you like an omlette, lightly cooked, with ham and bacon. You like your homefries crisp. You like a small orange juice. It is all ready for you moments after you walk in the door because Ava told the restaurant what you want and when you will arrive.Ava also knows that you want to keep your weight at a certain number. She tracks your calorie intake and creates food proportions and choice to meet your calerie requirements, tuned to the day's activities based on likely calorie burn.Ava reads books to you through the embedded speaker in your ear, tuning your book choice to the day.

Show HN: Interlock – Circuit breaker for AI infrastructure with signed auditshttps://news.ycombinator.com/item?id=46321932Interlock is a drop-in circuit breaker for AI systems (Express, FastAPI, core library) that tracks confidence, refuses low-certainty responses, and generates cryptographically signed certification artifacts and incident logs. It includes CI-driven stress tests, a certification badge, and reproducible benchmarks. Repo + quickstart: https://github.com/CULPRITCHAOS/InterlockWhat it doesTracks AI confidence, hazards, and triggers a reflex (refuse/degrade) rather than silently returning incorrect answers. Produces tamper-evident audit trails (HMAC-SHA256 signed badges, incident logs, validation artifacts). Ships middleware for Express and FastAPI; adapters for 6 vector DBs (Pinecone, FAISS, Weaviate, Milvus, LlamaIndex, LangChain). CI workflows to test, stress, benchmark, and auto-generate certification badges. Evidence artifacts are preserved and linkable.

Show HN: OmnAI – Sovereign AI infrastructure with multi-vault isolationhttps://github.com/TadTanyaTalaTadenTadhgTaya/OmnAI-v3.5Hey HN! I built OmnAI because enterprises keep telling me they can't deploy AI due to compliance barriers.The problem: Defense contractors need air-gapped LLMs. Hospitals want AI but fear HIPAA violations. Banks need audit trails for every AI decision. Current solutions either lock you into cloud providers or leave you on your own for security.OmnAI provides: - 16 isolated vaults using gVisor sandboxing (zero data leakage between tenants) - Trust-based governance - mandatory human review when confidence drops below 0.90 - Three deployment tiers: SUPERFLY (air-gap/DoD IL6), SOVEREIGN (on-prem/finance), EXCEED (hybrid/R&D) - Compliance-ready architecture (FedRAMP, HIPAA, SOC, ITAR)Technical stack: vLLM/Triton for inference, offline PKI with AES-GCM-256, per-vault fine-tuning pipelines.It's in pilot state - I'm looking for feedback on whether this architecture resonates with production AI challenges you're seeing, especially around data sovereignty and regulatory compliance.https://githubDec 18, 2025 3:19 PM
