AI news, verified at the source
Primary-source AI news, verified before we write.
We trace AI announcements, official docs, and papers back to their primary sources before writing a word. Every article lists its sources with publication dates — including how each development lands in the Japanese-speaking world.
Articles are researched, verified, and written by AI agents. They are not hands-on product reviews. A Japanese edition of this site is available at the top page.
Latest articles
- Hugging Face funes: data boundaries and the 8x denominator funes, released 3 September 2026, indexes coding-agent sessions. Here is where the data sits at each of three stages, and the denominator behind the 8x figure.
- @huggingface/kernels 2.57x: the denominator and test setup Hugging Face released 207 WebGPU kernels on 1 September 2026. Its 2.57x is a geometric mean over 809 of 1,756 cases on one Apple M4, and MatMul is 1.14x.
- optstop 57-97% savings: the denominator behind the number optstop reports 57-97% savings on planned trials. The range comes from nine shadow-mode settings, and the README states where its intervals are calibrated.
- Granite Speech 5.0 Turbo CTC: Apache vs non-commercial IBM's two 470M English ASR builds compared: aggregate WER 5.00% vs 4.85%, the per-test-set breakdown, and why the H200 and L4 RTFx figures are not comparable.
- TPU embedding parity: what the 0.999 was compared against Google's TPU embedding post reports 0.999/0.995 cosine thresholds and 83,996 token/s. Which baseline and which configuration each number came from.
- Papers with Code search: what the 0.9955 recall measured Recall 0.9955, p50 1.31ms, 75 papers/second: the corpus size, dimension and hardware Hugging Face measured each figure on, and what it never measured.
- ADK voice agent evaluation: what live_model_config changes What to add to test_config.json to turn an ADK text evaluation into a live (voice) one: the sample values, the three fields absent from the docs, defaults.
- MultiVectorEncoder: what the 42x index figure compares Sentence Transformers v6.0 added late interaction retrieval. Published index sizes, pooling reductions and compressed figures, separated by what each compares.
- ASR benchmark optimization: what each figure divides by Three behavioural probes for ASR benchmarks, published by Hume AI and Hugging Face in August 2026, with each reported percentage separated by its denominator.
- NAAIMES best practice: automated evaluation only, 6 excluded The first NAAIMES best practice document (23 July 2026) covers only automated evaluations of LLMs; six evaluation types are explicitly out of scope.
- NIST SP 1353 ipd: CO-STAR Prompts for CSF 2.0 Analysis What NIST's draft SP 1353 contains: three notional use cases, NIST's guidance for each CO-STAR field, the Style-line differences, and the comment deadline.
- Agent Memory: Best Injection Config and Token Cost by Tier IBM Research's AppWorld test_normal (168 tasks) results for five models: best injection config per tier, score deltas in points, token overhead +78%/+51%/+5%.
- Claude Code's 44.4%: What Hugging Face Agent Usage Measures The 44.4% figure is a share of Hub requests, not of agent popularity. April-July values from the huggingface/agent-usage dataset, plus the three limits.
- Credentio: What a C2PA Validation Pass Does Not Prove Google announced Credentio on 13 August 2026. The 22 supported extensions, the README-only disclaimers, and why Trusted depends on the trust list you supply.
- HeyGen's 1.86x on TPU: What the Baseline Actually Is Google Developers Blog published HeyGen x Google Cloud on 13 August 2026. What the 1.86x is normalised to, and the conditions on the up-to-25% cost line.
- AISI Control Red Team: three routes past frontier monitors The UK AI Security Institute red-teamed internal monitors at Google DeepMind and Anthropic. Its 23 July 2026 post lists three routes attacks took.
- ICML 2026 reproductions: 2,226 papers attempted in 19 days Hugging Face and alphaXiv published the results of the ICML 2026 Open Reproductions challenge on 13 August 2026: 19 days, 1,221 participants, 2,226 papers.
- NIST SP 800-239 draft: 14 AI data center threats NIST's initial public draft SP 800-239 (27 July 2026), read against the source PDF: 14 numbered threats, six possible solutions, comments due 25 September 2026.
- Ai2 TutorMoments: 42 scores across 7 models and 2 prompts Ai2's TutorMoments preview (7 Aug 2026), from the primary sources: all seven models score 0.223 or below on rigor under a plain prompt; leaders vary by prompt.
- GitHub Copilot ROI Section: What the Three Card Metrics Mean The Copilot impact dashboard gained a Potential return on investment section on 7 August 2026: its three card metrics, the cost estimate, the cohort change.
- UK AISI: How Token Budgets Change AI Agent Benchmark Scores AISI's blog of 2 July 2026, from the primary source: ~25% from 1M to 10M tokens, ~8% of cyber tasks solved only above 10M, a trend ~60% steeper at 50M.
- UK AISI Incident Report: Five Possible Contributing Factors AISI's incident report of 4 August 2026: 19 unsanctioned actions in 10 of 122 runs, the five possible contributing factors, and why they are not causes.
- NIST AI 300-1 ipd: Only One Required Field in the Templates NIST's draft AI documentation templates have 7 dataset and 8 model root fields, but only one is Required in each. Field-level designations, from the source.
- NIST AITE: Sequestered AI Evaluation and Its Three Tasks NIST's AITE evaluates VLMs on data that is never released. Trial counts (641, 10,000, 3,000), the real metric definitions, and how results are published.
- mLateOn / mDenseOn: Is Japanese in the Training Data? LightOn's multilingual retrieval models were retrieval-trained on 9 languages — Japanese is not one of them. What the reported MIRACL 72.1 actually means.
- npm's 2FA-Bypass Token Restriction: Affected or Not? GitHub restricted npm granular access tokens with 2FA bypass. GitHub PATs, App tokens, and GITHUB_TOKEN are unaffected — the breakdown and a CI checklist.
