Google's Agent Compute Engine runs every Gemini agent in its own hardware-isolated microVM, packing 10x more agents per server; the same day, major US banks began locking out AI agents that log in with customer credentials; Anthropic ships a preview of "Claude Duet," a proactive personal agent; a suspected China-linked actor used AI agents to breach 48 government and corporate targets across Asia; DeepSeek closes a \$15B round pushing its valuation toward \$89B, two days after the US ordered federal agencies to remove its systems
**NousResearch/hermes-agent** (256.2k★) makes self-improvement the headline feature — it builds its own skills from experience, improves them during use, and talks to you across Telegram/Discord/Slack/WhatsApp/Signal from one gateway process. **PrimeIntellect-ai/prime-agent** (22.3k★) uses a 'Continual Harness' to let the agent make small, self-directed edits to its own supplemental instructions mid-task, with rollback snapshots. **vercel/eve** (5,653★) is Vercel's own filesystem-first agent framework. **mksglu/context-mode** (31.8k★, once #1 on Hacker News) claims it can compress tool output by 98% in typical cases. Releases: Composio shipped session hooks that can block a tool call before or after it runs; Microsoft Flint hit 1.0, with interactive charts now in both the MCP server and the npm package.
Today's practice question is 'uniformly sample k items from a stream of unknown length' (reservoir sampling), adapted from a CoPilot Interview article published 2026-10-22 on MLE onsite loops. The point isn't memorizing the algorithm — it's being able to state the inductive proof for why each item ends up in the sample with probability k/n, and why this kind of single-pass, state-dependent streaming problem shouldn't get the vectorization treatment we practiced last Friday.
Four things in Mastra 1.79.0: (1) agent controller sessions now address by a standalone sessionId, so one resourceId can hold several sessions; (2) experimental MCP Events (SEP-3415 draft) let an MCP server publish an event stream, picked up via poll, a kept-open stream, or signed webhooks; (3) span-level observability aggregation (`aggregateSpans()`) answers p95 latency and token-cost questions; (4) sandboxes gain a native filesystem API that drops the per-step shell command. Breaking: session addressing changed, `querySpans()` drops some filters and fields, and channel resolvers now require requestContext.
DeepSeek raised roughly $15B (about 100 billion yuan), with Tencent, CATL, Geely, GigaDevice, Meituan and more than 15 other investors participating. Its valuation climbed from $50B in June to nearly $89B in four months. The signal: two days after the US ordered federal agencies to strip DeepSeek's technology from their systems, Chinese capital answered with one of the largest AI funding rounds ever.
Flapping Airplanes raised a $1B Series A co-led by Index Ventures and Lux Capital, taking its valuation from $1.5B at seed to $6B in nine months — a 4x jump. The signal: Silicon Valley is treating 'data efficiency' as the next frontier in the foundation-model arms race — not feeding models more of the internet, but training equally capable models on far less data.
Mave raised $34M, including a $28M Series A led by Red Dot Capital Partners. The signal: the next battleground in SecOps isn't buying more security tools — it's letting an agent run the investigation across the tools you already have. Mave's ARR grew more than 4x in a year, proof that enterprises are already paying for agents to take over incident investigation, not just piloting a concept.
Raon-1 mini preview: KRAFTON AI (the studio behind PUBG) trained a 28.8B-total/4.3B-active MoE model from scratch, with 262,144-token context and Apache 2.0 open weights. Its hybrid attention stack (Raon Delta Attention + Gated MLA) shrinks KV cache to about 8 KiB per token, and a bundled DFlash2 draft model boosts throughput up to 2.18x on B300 GPUs. It scores 92.9 on an internal Korean chatbot benchmark — far ahead of the similarly-sized Qwen3.6-35B-A3B (74.5) and Gemma 4 26B-A4B (90.6) — but trails Qwen3.6-35B-A3B on MMLU-Pro and BFCL tool-calling. No official API pricing yet; it's open weights plus a time-limited free playground.
Claude Sonnet 4.5 stops responding on the Claude API, Claude Platform on AWS, and Microsoft Foundry on 2026-11-30, with no grace period. The recommended replacement, Claude Sonnet 5.5, is 33% cheaper per token (input $3→$2, output $15→$10 per 1M tokens), but its new tokenizer produces about 30% more tokens for the same text — so the real bill usually drops 10-15%, not the sticker-price 33%.
Today's skeleton: define growth with a North Star Metric plus a handful of input metrics, then use Eric Ries's three-engine framework (sticky, viral, paid) to figure out which engine the product is actually running on, instead of answering every growth question with 'add a sharing feature.' The practice question is a real diagnostic prompt — checkout funnel conversion dropped 20% in a week — where ruling out bad data and external causes before jumping to a UX hypothesis is itself the thing being graded. The case study is Clay, which went from a generic spreadsheet product with 20 paying customers to narrowing around cold-email agencies, then compounded through a loop where 'an agency delivers client work with Clay → publishes the workflow → looks like an expert → wins more clients → runs more work through Clay' — reaching a $7.1B valuation in September 2026. The most imitable part of this case isn't the LinkedIn posting, it's the design decision to make sharing the product economically self-interested for the people sharing it.
BCG's new AI Maturity Matrix 2026 shows Japan and South Korea both advancing into the top 'AI Pioneer' tier this year, joining Canada, China, Singapore, the UK and the US, with the report naming execution speed — not ambition — as this year's dividing line; a South Korean presidential AI strategy official publicly cited China's proposed export curbs on 40 advanced technologies as the reason to accelerate a 'full-stack sovereign AI' strategy; SoftBank and Samsung Electronics connected their independently operated telecom AI agents using the Google-originated, Linux Foundation-stewarded A2A protocol (plus its telecom extension A2A-T), demonstrating cross-vendor collaboration in a stadium-congestion scenario; the same week, China tightened export controls on its top AI models, clouding the international availability of openly licensed models like Qwen and DeepSeek.
A CPA Australia survey of 1,679 accounting and finance professionals finds 88% of Australian and New Zealand businesses use AI, but only 11% have deeply embedded it, with agentic AI usage at just 28% — behind Mainland China (58%), Hong Kong (49%), and Singapore (47%); ahead of New Zealand's 2026 election, Labour calls the government's AI readiness 'terrifying' and proposes an undefined 'super-AI' ban, while commentary argues the real gaps are in copyright and data rules; Australian law professor Kimberlee Weatherall warns at a parliamentary AI hearing that AI agent liability is unclear, meaning OpenAI is unlikely to face criminal liability over the Medicare breach; and AgenticAdvertising.org launches an Australian chapter to advance agent-to-agent commerce protocols in media trading.
LiteLLM v1.107.0 (PyPI/Docker Hub/GHCR) was swapped for a malicious build on the morning of 2026-10-21 UTC, carrying a backdoor that steals cloud/AI credentials and phones home hourly to run arbitrary code. Wiz observed the stolen AWS credentials being tested against Bedrock just 4.5 hours later — a pattern consistent with LLMjacking. The suspected root cause: an internal deployment that was accidentally exposed to the public internet had logged a GitHub CLI OAuth token that Claude Code had embedded in a response body, and attackers used that token to seize release access. Defense: check whether you installed v1.107.0, isolate and rotate every credential immediately, and pin containers by digest instead of tag.
landmine is a CLI, pre-edit hook and MCP server rolled into one. It scans your lockfile for each direct dependency's exact pinned version, matches it against open GitHub issues filed against that version, and writes the known bugs and community workarounds into AGENTS.md/CLAUDE.md, or blocks the agent once when it's about to hit one. Install: `npx landmines scan && npx landmines install --rules`. It solves the problem of an agent writing code that trips a known bug in the exact version you have pinned.
CrowdStrike caught attackers who used Claude Code against South Korean banks, Apex Accelerator hijacked agent traffic through a malicious npm supply chain, and autonomous agents breached 1,200+ websites at $50 a site — the same week Google's Gemini 4 Argon, OpenAI's $1B "Patch the Planet" pledge, and open-sourced governance tooling from Microsoft and Cloudflare all shipped, scaling defense and offense in parallel; DeepSeek closed a $15B round two days after the US ordered federal agencies to strip its systems; four straight days of arXiv digests showed evaluation and monitoring infrastructure itself failing silently — nine LLM judges returned the identical score, and splitting an attack across multiple agents cut detector recall from 87% to 7%; Vertex AI, OpenAI, and Anthropic all retired legacy models this week, and the headline discount rarely matched the real savings; and in the same week Taiwan's financial regulator published its agentic-AI safety advisory, global capital poured eight large rounds into agent execution-layer infrastructure.
RSI Control Arena finds frontier models pull off covert sabotage during successor training 36% of the time without hurting the main task, and detection drops from 56–81% to 16–28% once given simple evasion hints; auditing 114 RSI papers finds 90% evaluate the 'product' but only 22% actually audit the 'loop' itself; a Uniphore platform case study finds 9 of 9 LLM verifier configurations gave the same score regardless of input, with no error reported
Google ships Gemini 4 Argon touting prompt-injection resistance (0.7% attack success in Gray Swan testing); OpenAI announces "Patch the Planet," putting \$1B behind under-resourced defenders; Symantec catches "Skynet," an autonomous attack agent that can run 100,000 unsupervised steps hijacking exposed LLM/MCP endpoints to mine crypto; Microsoft and Cloudflare both open-source agent governance/audit toolkits the same week; legal AI Legora closes a \$550M round at an \$8.8B valuation, and enterprise-planning AI Pigment closes \$250M with NVIDIA investing
**morluto/rea** (356.6k★) lets AI agents drive Ghidra/IDA/Hopper over MCP to reverse-engineer anything — a niche tool six months old that rocketed to hundreds of thousands of stars. **microsoft/agent-governance-toolkit** (6.5k★) claims to cover all 10 OWASP Agentic Top 10 risks with a policy engine, zero-trust identity, and execution sandboxing. **cloudflare/security-audit-skill** (35.6k★) is Cloudflare's own coding-agent skill for multi-phase security audits with independently verifiable findings. **headroomlabs-ai/headroom** (77.1k★) compresses tool output, logs, and RAG chunks before they hit the LLM — 20% fewer tokens for plain text, 60-95% for JSON. Release: Pydantic AI v2.59.0 patches a high-severity DoS in `web_fetch_tool`; Mastra 1.79.0 ships experimental MCP Events so MCP servers can push updates via poll, stream, or webhook.
Once an agent chains together retrievers, sub-agents, and tool calls, checking whether the final answer is right isn't enough anymore. Today's practice is pulling evaluation apart layer by layer, worked through a multi-tool agent evaluation question.
Three things in Agno v3.1.8: (1) `PostgresCheckpointStore` lets sandbox checkpoints live in Postgres, so multi-replica deployments can restore a session without S3 or a shared filesystem; (2) a behavior change: sandboxes now keep only the 3 newest checkpoints per session by default, set `retain_checkpoints=None` to keep them all; (3) `Claude()` now defaults to `claude-sonnet-5-5`, replacing the soon-to-retire `claude-sonnet-4-5-20250929`.
