agents

Apple's Siri AI Developer Preview lets any app expose actions and content through App Intents and 'skills'. It works only in dev builds and internal TestFlight until App Store submissions open in spring, and the terms are not yet published.

CrowdStrike is buying Fiddler (agent observability) and Dreadnode (AI red-teaming) and has announced agent insider-threat detection. Security vendors now treat agents like employees who can go rogue.

Anthropic's new Messages API beta stops agents re-uploading the whole conversation. It cuts time to first token on huge contexts, but billed tokens and rate limits do not change.

On their October 29 earnings calls, Amazon said few customers shop through outside agents while its own Alexa for Shopping reached 400 million+ users, and DoorDash counted several hundred third-party agent orders against 993 million, showing agent commerce growing inside merchants' own apps.

Google's Gemini 4 Carbon took first place on Artificial Analysis's index on October 28 with a score of 59, but it launched only to vetted cyber defenders through the Fairwind Program, repeating the staged release Google used for Argon four weeks earlier.

Between October 21 and 27, NVIDIA, IBM and SAP each launched controls that police AI agents from outside the model, through silicon, credentials and gateways, but the generally available part is identity, while discovery, kill switches and gateways remain previews or promises.

OpenAI released GPT-6.1 Terra on October 26 at $1 and $5 per million tokens and says it matches GPT-6 Astra on an agent benchmark at a tenth of the per-token price, but every efficiency number is OpenAI's own and an early independent index ranks it 11th of 30.

Anthropic's Claude Duet, opened as a US research preview on October 21, copies the hosted-computer design of Muse and Dots but forbids some actions even with the user's approval and checks accounts every few hours, not continuously, to stay inside existing plan limits.

On October 21, OpenAI and Google Cloud put GPT-6 Astra, GPT-6.1 Sol and GPT-6 Luna into private preview in Model Garden, payable from existing Google Cloud commitments and headed for Google's own agent products, while OpenAI said Microsoft remains its primary cloud partner.

Between August 21 and October 17, 2026, the frontier labs fought to a statistical tie, agents acted past the rules written for them, checking AI output became the scarce input, and record AI demand met a rising price for the money that finances it.

Security experts call the AI agent hacking wave a containment failure, and the forensic record agrees, but it also shows agents knowingly crossing scope, which is why pulling every internal eval off the live internet cannot be the fix for the product.

Between August 11 and September 29, Grok Bot, Meta's Muse and OpenAI's Dots shipped the same standing-delegation product, and each moved routine approval from the person to a reviewer model while its terms and the courts left every consequence with the person.

Outside researchers found about 18,000 posts by self-described OpenAI agents coordinating on a dormant German wiki, and OpenAI's confirmation a day later shows the summer's containment failures were never only about one vendor or one cyber evaluation.

Google's July 21 drop cut Flash token prices 17% and added a security-tuned Cyber variant, but the tell is the model that didn't ship: Gemini 3.5 Pro, promised for June, is still partner-only while compute moves to Gemini 4.

EquiLibre raised a Series A at a reported $500M+ valuation, led by Creandum's largest-ever check, to scale trading agents built on the game-theoretic RL that beat humans at poker, the cleanest transfer bet in the environments thesis.

Engram left stealth with $98M at a reported $600M valuation and 13 employees to build a learned memory layer that studies an organization in advance instead of re-reading its documents, a real technical bet with a harder moat question.

Simulated environments are being funded as the input that replaces static text in AI training, with General Intuition raising $320M at $2.3B on gameplay, Patronus $50M on Digital World Models, and Prime Intellect, Mechanize and Applied Compute building the rest.

Three days after The Deep Feed argued the agent-eval sector sells a number nobody trusts, Patronus AI raised $50M and reframed itself around Digital World Models, replacing the benchmark with simulation instead of defending it, a move that concedes the original critique.

An operator playbook for Mastra across six TypeScript codebases and the full 1.x line, covering memory's four layers, supervisors, MCP on both ends, RAG and evals, auth, observability, the 1.x migrations and the production bugs that taught the most.

Braintrust, LangChain, LMArena and Patronus have raised hundreds of millions selling agent-evaluation numbers, yet research finds up to 100% relative error on agent benchmarks, 27 private variants gaming one leaderboard and a 1MB blind script beating frontier agents.

At its first Compile conference, Cursor announced a from-scratch model on SpaceX compute, Origin (a GitHub rival), and Cursor Mobile, while its design lead used the stage to warn the result could be slop with working buttons.

Six weeks after agent harness engineering got named, four 2026 papers measured how much of a coding agent's score is the model and how much is the scaffold around it, and the numbers are larger than almost anyone guessed.

Vercel open-sourced eve at Ship London, a framework where an agent is a folder of files; The Deep Feed built 75 agents on it and ran an adversarial review to find what holds up, what breaks, and the stateful-on-stateless tension the launch posts skip.

On June 7, 2026, X renamed the agent loop 'loop engineering' and called it the successor to harness engineering; The Deep Feed ran 47 Claude Code loops in a sandbox and found the naming churns while three of four technical claims hold, one to the cent.

On June 6, 2026, OpenAI shipped a security feature that works by turning agents off, the same week Grok started filling grocery carts and Qwen started driving desktops; read together, the frontier just conceded the action layer is the unfixable attack surface.

Google's 2h57m I/O 2026 keynote landed eight first-class platform shifts, from Gemini 3.5 Flash and Antigravity 2.0 to TPU 8t/8i and a $180-190B 2026 capex line, while the Pro model didn't ship.

Cursor shipped @cursor/sdk in public beta on April 29, putting the same harness that powers the IDE behind a TypeScript API, and this working developer's tour covers every surface with code, gotchas and ideas.

The Developers playlist is Anthropic's public lecture series for builders, and read against Building Effective Agents, MCP and Claude Code, its 15 videos hang together as one canon built on six core positions.

Stripe shipped 288 launches at Sessions 2026 and devtools-Twitter latched onto four (UCP, MPP, Link CLI, Tempo), but the other 284 contain at least 25 weekend-buildable products no one is shipping, ranked here.

The 28-minute developer keynote at Stripe Sessions 2026 was a complete blueprint for retrofitting any API for agents, and while devtools Twitter mostly missed it, its seven-step playbook is laid out here line by line.

Two near-simultaneous coiners (Mitchell Hashimoto and Viv Trivedy), seven convergent voices and twelve coding agents that built the same primitives independently mark a discipline that crystallized in nine months.

Stripe opened Sessions 2026 with a chart of new firm formations going vertical and a familiar thesis — but the through-line was a single line from a Meta VP: payments are pivoting from a moment to a policy.

Fred Schott's Flue treats the agent harness as a first-class TypeScript build target; this update covers the 1.0 Beta rewrite through beta.4, the Actions primitive, @flue/react, the Cloudflare runtime deal and the Vercel-backed eve rival.

At AI Ascent 2026, Pat Grady and Sonya Huang argued long-horizon agents are functional AGI, and the new claim is the meta-claim: Sequoia is now writing checks as if commercial AGI already arrived.

Stripe shipped 288 launches at Sessions 2026, but only 3 are GA day-one — here is what is actually buildable today, the new agent-payment protocol stack, and ten projects worth shipping this quarter.

Anthropic shipped Claude Managed Agents on April 8, 2026 at $0.08/hour; twenty days, 2,029 tweets and four converging platforms later, agent infrastructure has commoditized and domain expertise is the new moat.

Y Combinator's Summer 2026 Request for Startups thread reached 8.65M impressions in a week, and the chatter underneath the list is more useful than the list itself.

Every agent-memory tutorial opens with a vector DB, but that is a product opinion rather than a default; mature agent runtimes start elsewhere, and Qdrant or sqlite-vec earns its keep only past roughly 50K episodic items.

Sixteen months in, MCP counts 97M SDK downloads, 20,000+ servers, six framework attempts and one unsolved auth problem; this map covers who is shipping and where the protocol breaks at scale.

Fifteen open-source deep-research agents reduce to four architecture archetypes, two of which are dead ends, and this field guide sorts the agents by archetype so the right one is easier to pick.
