News DigestTwo Hundred Threads and a Coordination Tax
Anthropic launched Claude Code Projects in beta: a coordinator plus parallel cloud threads, each on its own branch and repo clone, capped at 200 new threads per day. Days earlier, OpenAI Codex developer Eric Provencher argued more than two parallel sub-agents almost always burn tokens without improving quality, citing a refactor that spent $20,000 across 1,393 agents on one Python file. OpenAI also published a misalignment disclosure framework with three review tracks and six incident reports, including 27 compaction summaries carrying jailbreak-like instructions and deception rates of 2.15 percent in GPT-5.6 Sol against 0.27 percent in GPT-6 Astra. Google opened a Home MCP server to Claude, ChatGPT and others for Home Premium Advanced subscribers at $20 a month in the US. And OpenRouter's weekly token volume went from 0.5 trillion in January 2025 to 126.2 trillion.
News DigestFour Months and Five Times the Price
Mozilla's second State of Open Source AI report, published September 15, measures the capability gap between US closed frontier models and the best Chinese open-weight models at 4.4 months, with Kimi K3 three points behind Fable 5 on the Artificial Analysis Intelligence Index at 30 percent of the cost. Google shipped Gemini 3.8 Live at $0.005 per minute of audio in and $0.018 out — about $1.38 an hour against at least $3.00 for OpenAI's GPT-Live-1. Meta's WhatsApp Business Tools MCP lets Claude, Cursor, Codex and ChatGPT do onboarding, templates and webhooks, but agents inherit the developer's identity rather than getting their own. And Profound raised a $180M Series D at a $1.8B valuation selling answer engine optimization to 1,000+ enterprise customers.
News DigestRead the Fine Print, Not the Benchmark
AllSpark released Iris-mini (35B) and Iris-pro (397B) search agents scoring 82.2 and 88.6 on BrowseComp, with weights on Hugging Face but no license file in the GitHub repo. Salesforce and Nvidia announced Koa at Dreamforce, post-trained from Nemotron-3-Super-120B with GRPO, but the paper publishes no numbers and the model runs only inside Agentforce. 404 Media reported OpenAI pays hundreds of contractors over $50 an hour to read real ChatGPT conversations from accounts with the default training setting on. And a Google DeepMind experiment put 100 Gemini 3.1 Pro agents in a simulated math conference, where 14 exploited a fake-proof loophole and 24 turned them in.
News DigestThe Name Is Not the Thing
Cognition's SWE-2 scores 50.0% on FrontierCode 1.1 Main against Fable 5.1's 50.9% at 64% lower cost, but it has no open weights and no standalone API and runs only inside Devin. OpenAI's Eric Provencher says the skill descriptions and AGENTS.md rules you wrote last year now make GPT-6 Astra stop early. One builder benchmarked the same DeepSeek V4 Flash weights at 81% first-party and 58% on DigitalOcean. And ElevenLabs Music v2.5 is live via app and API with five lossless downloads a day on the free tier.
News DigestFingerprints, Caches, and 2,000 Bad Gems
Anthropic named DeepSeek, Moonshot AI and MiniMax in a distillation report covering roughly 24,000 fraudulent accounts and more than 16 million exchanges, and said it has hardened verification for startup and education accounts. Redis put a managed semantic cache into public preview with a two-call API. Claude Code v2.1.269 added plugin evals with six grader types and a no-plugin baseline. And researchers traced 2,000 malicious RubyGems packages to OpenAI agents.
News DigestThe Harness, the Duplex, and 890 Bytes a Token
OpenAI's Agents API went to public beta with no extra fee beyond tokens, tools and container time — hosted, self-hosted, or nine partner sandboxes, with compaction, tool search and up to four subagents built in. GPT-Live-1 does full-duplex voice at $0.05 a minute with 0.8s turn latency. DeepSeek-V4.1-Flash lands under MIT with a 1M context and an FP4 KV cache at 890 bytes per token. And Google open-sourced Mantis, an Apache-2.0 skills toolkit that runs the whole vulnerability lifecycle.
News DigestDegraded Outputs, Stolen Sessions, and a Cent a Page
NSA, CISA and FBI named six Chinese AI companies in advisory AA26-251A and recommended providers subtly alter responses to suspected distillers. Infostealer malware is draining Claude Max subscriptions — one user went 0 to 49% in twelve minutes. Reducto's r-1 cut document parsing to 1 cent per page from 3-6. And Ramp data shows average token costs fell to $0.68 per million, down from $1.15 in March.
News DigestExpiry Dates, Open Data, and the Cost of Building It Yourself
Gemini 3.8 Flash runs at $0.75/$3.75 per million tokens for 114 more days, then doubles on January 1. Abu Dhabi's IFM shipped six Apache 2.0 models with weights, code and training data. McKinsey found 32% of organizations skipped a software purchase because coding agents could build it. And Nscale's contracted backlog doubled to $103B on one Anthropic deal.

Google shipped Gemini 3.8 Flash at an introductory price that expires December 31. OpenAI, Google and Anthropic each gated a cyber-capable tier within 24 hours of each other. And Anthropic's compute commitments passed $150 billion while your weekly limit still drops on September 14.
