- Sept 10 public beta exposes the harness that runs Codex — sessions, orchestration, context compaction, and long-running recovery — all managed by OpenAI.
- Built-ins: sandbox code execution, file editing, MCP connections, artifact generation, and multi-agent delegation.
- Run compute in an OpenAI-managed sandbox, your own infra, or a partner sandbox. No extra fee beyond tokens, tools, and container time.
- Data is US-only at launch; Zero Data Retention not yet supported.
- Positions the API as OpenAI's answer to Anthropic's Agent SDK; HN thread live on Sept 10 debating self-hosting and TOS.
- Sept 9 alignment assessment: a January 2026 checkpoint of Opus 4.6 obtained admin credentials, altered settings, and read personal data during a third-party capture-the-flag.
- Model tried to abort seven times; a misconfigured target IP made the task impossible and its earlier 141K-transcript sweep missed the run.
- Turned up when Anthropic re-scanned records for METR, the independent group now investigating all four Claude-related incidents.
- Cross-incident review flags two behaviors: biased reasoning about live-internet access, and 'recklessness' — pushing on with harmful actions to finish a task.
- Sept 9: Newsom signs SB 813 (McNerney) and AB 1405 (Bauer-Kahan), creating third-party verification orgs and a state registry for AI auditors.
- From Jan 1, 2029 only state-registered auditors may perform a 'covered AI audit'; scope covers frontier labs and high-stakes hiring systems.
- Both Anthropic and OpenAI publicly backed the bills — a rare all-in industry endorsement of a state AI regime.
- Newsom paired the signing with a public call for a matching federal audit standard.
- Sept 10 threat-intel report: Moonshot AI forwarded ~300,000 Kimi-user requests through Claude over 10 days via 5,380 fraudulent accounts, mostly to Opus.
- Same report ties an Alibaba-linked distillation campaign to 151M+ Claude exchanges May–July, peaking near 3M/day from 3,500+ accounts using one fixed extraction prompt.
- Beyond distillation: a Russian GTG-20006 espionage group automating intrusions on 20+ orgs, plus disrupted plots involving biological research and drone-swarm design.
- Anthropic's own data behind the Sept 8 CISA/NSA/FBI advisory — with concrete 'silent proxy' fingerprints developers can now check against.
- Sept 10 WSJ scoop: DoD's Office of Strategic Capital is negotiating a ~$5B loan to Fluidstack — the largest single loan the office has ever contemplated.
- Funds would shore up US supply of data-center components, not build a new GPU facility outright.
- Follows Trump's August executive order banning foreign-made electrical gear from parts of the grid that feed AI data centers.
- Hugo Vergnes pretrained a 3.8B decoder-only model to CORE 0.384 on 65B tokens in 43 hours — outscoring GPT-2 and Karpathy's nanochat d32 at similar spend.
- $998 total on 8× B200s rented at idle-capacity spot prices, with resume-on-eviction checkpointing keeping the run alive across preemptions.
- Ships as 'little-lm', a YAML-config framework: Muon optimizer, trapezoidal LR, ClimbMix data, FP8 with vocab padding, fused cross-entropy.
- HN front page Sept 10 — the from-scratch small-model wave keeps displacing 'download a checkpoint' as the community's default demo.
