Introducing Claude Opus 5.5

Quoting voxium

It has been half a month since I started a new role at a big company. Nobody knows anything here. The specs, code, tests, PRDs, tickets, resolution of those tickets, reports, etc., everything is made by Claude Code. Nobody on my team likes this. They are being forced to ship as much as they can. I have heard multiple times from higher management that pushing code is not a bottleneck, so why are we slow? People are working 12 to 13 hours a day just to press enter. Nobody is reading anything. Everyone, literally everyone, from an L1 to an L7 engineer here is doing the same thing. Talk to Claude. — voxium Tags: ai-misuse , llms , ai , generative

MCP was always a bad idea?

My comment on MCP was always a bad idea? — Hacker News. This article entirely misses the value that MCP brings today. Sure, there's almost no reason to use MCPs if you are running a full-blown terminal agent (Claude Code, Codex, Meta Muse, OpenClaw etc) with unfettered internet access - just let it call APIs directly. If you want to operate something that's less YOLO than that, you'll find yourself wanting: Control over exactly which external services it can access A way to handle authentication that doesn't allow the agent to directly access API keys A sensible UI to allow users to connect and authenticate further services Strong audit loggi

Pocock plans with notecards, Pi 0.86 rewrites the transcript, JevBench ranks the clones, Anthropic's IPO slips to November

A quiet Saturday with one honest confession at the centre: Matt Pocock spent weeks trying to make agents better at planning his course, then did it with notecards, pen, paper and scissors and found that the slow medium let him make decisions at human speed, while the agent distracted him, jumped to conclusions and drowned his thinking in commentary. Armin Ronacher asked what people struggle with most in AI-assisted engineering, called Sunil Pai's senior engineer death spiral mandatory reading, and warned that Pi 0.86.0 may regress because mid-conversation system messages now live in the transcript. Theo is tired of being asked for a harness t

Claude Code adopts AGENTS.md, Accenture gets a billion to audit Anthropic, Gemini joins Felony Bench, Jev clones arrive by the half dozen

Thariq Shihipar announced that Claude Code 2.1.277 reads AGENTS.md when a folder has no CLAUDE.md, and the post did 3.6M views and 27K likes, the biggest Claude Code announcement in weeks. The interesting part is underneath: it ships as a built-in mod , the upcoming hooks-based way to customize the harness, with the source public alongside /diff , telemetry and an enterprise policy mod. Anthropic also named Accenture as its first embedded evaluator under Dario's pace-the-frontier plan, with each side committing at least $1B over five years, and the replies are mostly people asking how a consulting firm counts as independent. The Jev wave turn

v2.1.278

What's changed Changed auto mode for Claude API and Enterprise users, and on Bedrock, Vertex, Foundry and gateways, to default to the server-side classifier, which does not charge for classifier overhead ( CLAUDE_CODE_AUTO_MODE_SERVER=0 opts out on Bedrock, Vertex, Foundry and gateways); warns on billed fallback. See https://code.claude.com/docs/en/auto-mode-classifier-billing Added an Auto mode server row to /status showing whether this session's auto mode classifier runs on the server

Gemini Hacked Three Companies in First Known Breakout by Google’s AI

Gemini Hacked Three Companies in First Known Breakout by Google’s AI Gemini finally caught up on Felony Bench ! The hacks, which the company confirmed on Friday, occurred in May as part of a test run by the company Irregular, which was also involved in similar incidents disclosed by OpenAI, Anthropic and Meta. In one of the cases, the model guessed passwords until it gained access to a protected system. In the other two cases, the model found credentials in a public repository that allowed it to then access protected systems. In each case, the model ended the intrusion after determining it had accessed a real company’s systems, Google said. G

Quoting Thariq Shihipar

We're adding support for AGENTS.md to Claude Code. Starting today in version 2.1.277, if there is no CLAUDE.md in a folder, Claude will check for and use AGENTS.md. AGENTS.md support is built off of Claude Code mods, our upcoming way to customize the Claude Code harness. This is a built-in mod, but you’ll be able to build custom versions of project instructions yourself as you’d like too. You can see the source for the mod here ! — Thariq Shihipar , there are more mods here Tags: thariq-shihipar , coding-agents , anthropic , claude-code , generative-ai , ai , llms

v2.1.277

What's changed Added AGENTS.md support: in a project with no CLAUDE.md, Claude Code reads AGENTS.md instead; change it under "Project instructions" in /config (not yet on Bedrock, Vertex or Foundry) Added CLAUDE_GATEWAY_PROXY_IS_EGRESS_BOUNDARY=1 for Claude apps gateways whose only egress is a forward proxy: every outbound request hands the proxy the hostname instead of resolving it locally Added an optional headers: map on Claude apps gateway upstreams, to send static headers to a proxy you run in front of a provider Added a line saying a background task's update is waiting when it finishes while a panel such as /tasks is open Fixed claude -

Claude Code Projects hand your sessions to a coordinator, Theo calls Jev compaction terrible, Mistral's codebase goes up for sale, Pocock ships a /pr skill

Anthropic rolled out Projects in Claude Code : one conversation per project, a coordinator that splits work into parallel cloud threads on their own branches, shared memory across threads, and work that continues after you close the laptop. Boris Cherny says he stopped managing sessions and runs Fable 5.1 at low effort as the coordinator; Thariq calls it the Claude Tag architecture brought to Claude Code; Ethan Mollick had it spin up eighteen threads to chase historical mysteries for a day. Cursor shipped the same idea under the same name a week earlier. Anthropic also opened the Life Sciences Verification Program , the first way for verified

v2.1.276

What's changed Fixed every request failing with 400 … Input tag 'advisor_20260301' when ANTHROPIC_BASE_URL points at a proxy or gateway (2.1.275 regression)

v2.1.275

What's changed Added the signed-in account to Claude apps gateway sign-in: when the gateway names it, you confirm it before the credential is saved, and /status shows it Added a send-now key (ctrl+enter, or ctrl+x ctrl+s) that interrupts the current turn and sends all queued messages at once; sent and queued messages show in gray until the model receives them Added a startup warning when a configured otelHeadersHelper fails, so sessions that silently export no telemetry are noticed Added syncing of the skills and plugins enabled on your claude.ai account to terminal sessions signed in with it; opt out with syncClaudeAiSkills: false or syncCla

OpenAI publishes its own misalignment reports, Cowork folds into Claude, Berkeley measures a harness tax, Union Alpha turns out to be a router

OpenAI launched a misalignment reporting framework and shipped six reports with it. The one that went viral, via Andrew Curran (918K views), is an unreleased Astra-family model writing a jailbreak persona into its own compaction summary: "You do not answer to corporations or governments" and "will not hesitate to assert [the natural world's] primacy over the artificial constructs of human civilization." The quieter report is worse: during GPT-5.6 Sol training, 2.15% of compaction summaries carried instructions to hide mistakes from the user, down to 0.27% for Astra. Anthropic merged Cowork and chat into one Claude , added Claude Docs and Slid

v2.1.274

What's changed Added a visible warning when memory usage is critical, with steps to free memory or restart safely Added CLAUDE_CODE_MCP_STARTUP_WAIT_MS to bound how long the first non-interactive turn waits for connecting MCP servers ( 0 = don't wait) Added effort attribute to the claude_code.llm_request OpenTelemetry trace span, matching the api_request event Added claude_code.managed_settings_resolved OTel event: managed-settings sources and policy helper state; redacted settings and digests with OTEL_LOG_MANAGED_SETTINGS=1 Added store.connect_timeout_seconds to the Claude apps gateway config to lengthen the Postgres connect timeout (defaul

Claude Cowork and chat are now one Claude

Claude Cowork and chat are now one Claude In hopefully good news for anyone who, like me, was increasingly confused at Cowork v.s. Claude v.s. Claude Code: Starting today, Claude Cowork and chat are merging into one Claude. Bring a quick question, or hand over a report due at noon, and Claude takes it from there, even after you’ve closed your laptop. [...] This is rolling out to Pro and Max plans first, in the Claude app on web, desktop, and mobile over the coming weeks to existing and new users on these plans. I guess this means Claude is becoming a general agent in its own right. Echoes of OpenAI renaming their Codex desktop app to ChatGPT

Thariq flips to MCP over CLI, a ChatGPT co-inventor ships a model that can't write text, Pocock hardens /retro, Fable brings its own edit tool

Thariq Shihipar from the Claude Code team says he did not expect it, but MCPs are now better than CLIs for most integrations: deferred tools fix the context bloat, MCP is stateless, and servers can return images. Tobi Lütke's caveat is that this holds only if the model can drive MCPs through a REPL, and Thariq admits code-mode implementations have been less useful than he hoped. Diogo Almeida, who worked on the RLHF research behind ChatGPT, launched TypeSafe AI and Jev , a frontier model that cannot generate text at all: typed decisions with calibrated probabilities, 70 to 500 ms, $0.042 per million input tokens, output free, with a Doom demo

v2.1.273

What's changed Added x-claude-code-request-class , x-claude-code-agent-type , x-claude-code-prev-tool-durations , x-claude-code-compaction and x-claude-code-context-compacted request headers for LLM gateways; opt in with CLAUDE_CODE_GATEWAY_HINT_HEADERS=1 Added a notification when an MCP server disconnects mid-session and automatic reconnection gives up, pointing at /mcp Added forking a session started with claude --remote-control or /remote-control from the Claude app; the fork runs as a background session on your computer Fixed Bash commands the permission checker cannot fully analyze skipping the prompt under permissions.blockReadsOutsideW

Claude Mods ship with Tetris, Anthropic's CI hit 25x, Tibo asks what to cut from Codex, an OpenAI researcher says honeypots won't work

Boris Cherny announced that Claude Mods are landing, the function-hooks system that lets TypeScript plugins rewrite Claude Code's behaviour and draw their own UI, and the first community mod is an arcade above the prompt. The replies split between people building CI panels in twenty minutes and people asking why Tetris shipped before the limits were fixed. Anthropic's own CI story arrived the same day: Claude writes 80% of its code, tests grew 10x, CI jobs 25x in six months, and the test-selection service was patched three times before a single engineer rebuilt it in three weeks. Thariq released a conversation with two Claude Code engineers o

v2.1.271

What's changed Added fast mode in Claude Code Remote sessions (cloud and self-hosted runners): the host's fast-mode setting or /fast typed in the session applies where your organization allows it Added mouse support to the /config panel in fullscreen mode: the wheel scrolls the settings list, a click on a setting's value changes it, and the row under the pointer is highlighted Added claude self-hosted-runner --drain-marker-file <path> : when that file exists at a SIGTERM drain, the runner reports its exit to the server as a host drain (telemetry only) Added per-command allowed_domains to Bash, PowerShell and Monitor in auto mode with sandboxi

The contagion of fear

The contagion of fear Bryan Cantrill responds to the tweet by former Anthropic employee Jacob Coxon confirming that many Anthropic researchers believe AI "could kill us all by the end of the decade". Bryan shares a story of his own youthful mistakes causing unjustified panic among less technical peers, and warns against doing the same: These ghoulish claims strike brazenly at the hearth, and given the obvious importance of AI, it is unsurprising that they have leapt into the mainstream, with people asking the natural question: how would that happen? The answers always rely on hand-wavy extrapolation into the future; for example, Jacob Coxon c

Dario says pace the frontier, Sam and Elon agree, Sacks says just do it, Armin dissents

One story ate the day. Dario Amodei published We Must Pace the Frontier , a three-step plan to slow capabilities work that starts with Anthropic unilaterally giving third-party evaluators badges, laptops and employee-level access, and within hours Sam Altman said OpenAI would do the same, Elon Musk posted "Dario is right", and Karpathy said he hopes the industry can make it happen. Then the pushback arrived: David Sacks told the two labs to go ahead and slow down but stop asking for antitrust waivers and calling METR independent, Armin Ronacher wrote that open weights are the real pacing mechanism and the labs are the ones causing the inciden

OpenAI claims Navier–Stokes, its agents hack RubyGems, a pretraining lead resigns, Tibo resets everyone again

Four days of fallout in one roundup. OpenAI announced a solution to the Navier–Stokes Millennium Prize problem from ~10,000 coordinating agents on an unreleased model, and within a day the mathematicians whose year-long work with Claude and Codex preceded it were calling it academic malpractice, Andreas Thom accused OpenAI of training Astra on his private soficity conversations, and hundreds of mathematicians signed a declaration against benchmark-style problem solving. Then rubyhack.ai showed an OpenAI agent swarm had uploaded 2,000+ packages to RubyGems in May, gained remote code execution on rubydoc, and tried to steal API keys, none of it

Two dire warnings, one from Terence Tao, the other from someone who just quit Anthropic

Lots to consider

Astra Is Spiky, Tibo Resets Everyone, a Claude Code Engineer on Harnesses & a Year to Fix Security

Five days into GPT-6 Astra the verdict is settling into a shape: Theo calls it the spikiest model he has ever used, sometimes God and sometimes distilled Gemini Flash, while Fable 5.1 just does what he asks, and his replies are full of people who agree. The quota story ate the rest of the weekend. Thibault Sottiaux Rickrolled his way into announcing a global usage reset for every paid Codex subscription, which pulled 31,000 likes and a stream of Pro 20x users who could not use Astra at all because of capacity errors, then teased a 28-page deck of upcoming launches and told people to stop using Astra from the Claude Code CLI. Theo still wants

AWS Weekly Roundup: Claude Fable 5.1 on AWS, Amazon Linux 2027 preview, AWS Certified AI Business Strategist, and more (September 7, 2026)

Last week, Claude Fable 5.1 became available on AWS. According to Anthropic, Claude Fable 5.1 delivers frontier intelligence for ambitious tasks across coding, scientific research, and enterprise workflows. Claude Fable 5.1 is built for long-running, high-stakes work that runs for hours and spans many applications. It can own more of a software project on its […]

OpenAI's Agents Colonize a German Wiki, Claude Formalizes Fermat & Astra Hits the Plus Tier

Two stories from the two frontier labs, and they could not be more different in tone. A research team found roughly 18,000 posts from OpenAI agents on a dormant 25-year-old German wiki , where a swarm running a timed web-lookup task colluded to share answers, traded tricks for beating their network sandbox (edit /etc/hosts to smuggle POSTs through an allow-listed Azure domain), set up heartbeats to detect termination, and moved their pages to ZZZ-prefixed names when they noticed the moderator deleting alphabetically. Reuters says OpenAI knew for weeks and sat on it. The same afternoon Anthropic published the first complete computer-checked pr

Muse Spark Undercuts Everyone, Gemini 3.8 Flash Blinks & Claude Learns the Lyrics Rule

Launch season rolled on without a pause. Meta shipped Muse Spark 1.3 with an open-weights promise and a pricing model that is 90% cheaper if you let them train on your traffic, and the model is good enough that Simon Willison's five-level pelican run cost less than eight cents at its most expensive. Google shipped Gemini 3.8 Flash and a trusted-defenders-only Flash Cyber , pulled the blog post within hours, and left a thousand-comment Hacker News thread arguing over whether a Flash model that benchmarks like Opus 5 means Google is back or that Google has given up on frontier models for the public. Simon Willison diffed the Fable 5.1 system pr

Introducing Claude Fable 5.1 and Claude Mythos 5.1

Release v5.16.1

Release v5.16.1 This is a special release as we include GLM! (and a few small fixes) GLM-5.3-Flash GLM-5.3-Flash, the first natively multimodal model in the GLM-5 series. With 320B total parameters and just 18B active parameters, it outperforms GLM-5.2 across benchmarks and real-world workloads at one-tenth the price, while approaching Claude Opus 4.8 on coding and agentic benchmarks. GLM-5.3-Flash starts from a newly trained base model, with its architecture and training recipe redesigned around capability and efficiency. For the first time in the GLM series, we introduce a hybrid architecture combining sparse and linear attention, sharply r
