+# Daily brief — 13 September 2026
+
+Standing-up day. This brief is the first radar sweep, not a full 40-minute harvest of every primary.
+
+## Frontier and markets
+
+- **GPT-6 Astra** (OpenAI, 3 Sep) remains the week’s gravitational event. OpenAI frames it as a generational step for computer use and has used “Critical” cybersecurity language under its preparedness framework. Independent boards after Artificial Analysis v4.3 put Astra in a **tie with Claude Fable 5.1** on the Intelligence Index (53) at materially lower reported cost-per-index-task. ARC-AGI-3 headlines (99.9% with a provider adapter vs ~63% on the ARC Prize harness in public write-ups) are a measurement scandal and a capability signal at once.
+- **Claude Fable 5.1** (1 Sep) is generally available; **Mythos 5.1** is a restricted sibling with safeguards lifted for verified programs. Cache-read pricing cut is an economics event, not only a model event.
+- **Gemini 3.8 Flash** GA (2 Sep). **Gemini 3.5 Pro** still not generally shipped — availability gap.
+- **Grok 4.7** still not shipped as of tonight; **Grok 4.6** (12 Aug) remains xAI’s current flagship. Musk comments last week pointed at RL length-penalty issues.
+- **DeepSeek V4.1 Flash** and **Cognition SWE-2** (10 Sep) compress the coding-agent cost curve: near-frontier coding at a discount.
+- Capacity: mid-September reporting that OpenAI paused some ChatGPT Pro signups/upgrades. Treat **availability as a first-class ledger field**.
+
+## Science of intelligence
+
+- Daedalus 2026 intelligence essays remain the best current bridge texts: Tenenbaum (language + probabilistic programs), Ganguli (physics + neuroscience + AI as one science).
+- NeuroAI: Wang’s “foundational brain model of intelligence” program (PFC-centric, multi-task recurrent circuits) and Pathway’s BDH latent-space reasoning architecture (cost-efficiency claim on ARC-AGI-1) are the two architectural stories worth tracking beside transformers.
+- In-silico cognitive science: AutoCog-on-Centaur work circulating this month argues theories discovered on behavioral foundation models can generalize to humans. Watch replication, not the press title.
+
+## Engineering
+
+- Agent evals, not chat evals, are the ruler: Terminal-Bench 4.0, OSWorld 2.0, AutomationBench-AA, SWE-Pro / DeepSWE / Frontier Code.
+- Index rebases (AA v4.2 on 4 Sep, v4.3 on 7 Sep) rewrote last week’s rank story. Never quote an Intelligence Index number without the version.
+
+## Political / legal / social
+
+- US congressional leadership publicly agrees risks are rising and that there is no quick statute. Track actual text, not Sunday shows.
+- Amodei slowdown essay and Anthropic distillation accusations toward some Chinese labs are both policy objects. Treat accusations as claims until evidence is public.
+- OpenAI IPO timing chatter is not a capability event.
+
+## Ledger actions
+
+1. Freeze Task Router recipes onto **AA v4.3 + work-sample evals**.
+2. Tag Astra and Fable 5.1 as joint general Frontier until a task-specific eval breaks the tie.
+3. Add DeepSeek V4.1 Flash and SWE-2 to the Budget / Efficient watch for coding tasks.
+4. Do not list Grok 4.7.
+
+## Sources to re-open tomorrow
+
+Artificial Analysis Intelligence Index v4.3 article; Epoch benchmark hub; OpenAI Astra card; Anthropic Fable 5.1 card; ARC Prize Astra measurement notes; lab pricing pages.

+# Weekly digest — 2026-W37 (7–13 September)
+
+Inaugural week. Ranked by decision relevance for Intelligence Radar.
+
+1. **Artificial Analysis rebased the Intelligence Index twice (v4.2 then v4.3).** Terminal-Bench 4.0 and AutomationBench-AA entered the composite. Headline: Claude Fable 5.1 and GPT-6 Astra tied at 53. Old scores are not comparable.
+2. **GPT-6 Astra launched (3 Sep).** Computer-use and cybersecurity-preparedness framing; wrapper-sensitive ARC-AGI-3 numbers; capacity constraints on Pro plans reported later in the week.
+3. **Claude Fable 5.1 generally available (1 Sep); Mythos 5.1 restricted.** Cache-read price cut changes long-agent economics.
+4. **Gemini 3.8 Flash GA; Gemini 3.5 Pro still missing.** Google’s usable frontier is a Flash-class model this week.
+5. **DeepSeek V4.1 Flash + Cognition SWE-2 (10 Sep).** Coding-agent Pareto moved; Budget/Efficient picks for software work must be revisited.
+6. **Grok 4.7 did not ship.** Grok 4.6 remains the xAI reference.
+7. **Meta Muse Spark 1.3** continues Meta’s closed frontier line at aggressive prices on some trackers.
+8. **Measurement politics:** harness gaps (ARC-AGI-3) are now large enough to mislead buyers. Radar rule: name the harness.
+9. **Policy:** US leadership acknowledges rising risk without a bill; Amodei slowdown proposal; cross-border distillation allegations. No new binding global rule this week.
+10. **Science-of-intelligence stack** is alive independently of product launches: NeuroAI foundational-brain proposals, complementary cognitive/machine AI frameworks, latent-space recurrent architectures.
+
+## Frontier one-pager
+
+Joint general Frontier: **Fable 5.1 ↔ Astra**.  
+Default Efficient generalist: **Opus 5** (task-dependent: Terra or Grok 4.6).  
+Default Budget with evidence: **DeepSeek V4.1 Flash / GLM-5.3-Flash** depending on jurisdiction.
+
+## Compendium edit proposals
+
+- Add “harness is part of the model” as a measurement principle. (Accept.)
+- Do not add Grok 4.7 until a model card exists. (Accept.)
+- Watch Pathway BDH as an architecture outlier, not a product Frontier. (Accept.)
