Claude Pulse

Anthropic launches three new features for Claude Managed Agents: (1) Multiagent orchestration in public beta — a lead agent divides complex tasks among specialist sub-agents, each with its own model, prompt, and tools, working in parallel on a shared filesystem and feeding context back to the lead agent, fully traceable through the Claude Console; (2) Outcomes in public beta — developers write a rubric describing what success looks like, and a separate grader evaluates the output in its own context window and prompts revisions; in internal testing, outcomes improved task success by up to 10 percentage points over a standard prompting loop with the largest gains on harder problems, and improved file generation quality by 8.4% for docx and 10.1% for pptx; (3) Dreaming in research preview — a scheduled process that reviews agent sessions and memory stores, extracts patterns, curates memories, and surfaces recurring mistakes, converged workflows, and team-wide preferences that a single agent can't see on its own; especially useful for long-running work and multi-agent orchestration. Memory also enters public beta.

Bloomberg reports Anthropic signed a computing deal with SpaceX to meet surging demand for its Claude AI software — Anthropic gains access to more than 300 megawatts of capacity and over 220,000 NVIDIA GPUs (H100, H200, and next-generation GB200) at SpaceX's Colossus 1 data center in Memphis within the month; the deal hands IPO-bound SpaceX a marquee customer to validate its AI ambitions to investors while easing Anthropic's capacity constraints amid surging demand for products like Claude Code; Anthropic also signaled interest in partnering with SpaceX to develop multiple gigawatts of orbital AI compute capacity.

Anthropic announces a compute partnership with SpaceX and raises Claude usage limits — gains the entire capacity of SpaceX's Colossus 1 data center in Memphis (more than 300 megawatts and over 220,000 NVIDIA GPUs including H100, H200, and next-generation GB200), coming online within the month; usage limits across paid Claude subscriptions rise correspondingly: Claude Code five-hour rate limits double within the month for Pro, Max, Team, and Enterprise customers, peak-time throttling for Pro and Max accounts is removed entirely, and API limits for Claude Opus models receive a major increase; Anthropic also expressed interest in partnering with SpaceX to develop multiple gigawatts of orbital AI compute capacity.

CNBC reports Anthropic founder and CEO Amodei warns of a 'moment of danger' — Mythos has uncovered tens of thousands of software vulnerabilities, leaving roughly a 6-to-12-month window before Chinese AI models catch up; an earlier Anthropic model found about 20 vulnerabilities in Firefox while Mythos found nearly 300; Amodei: 'The danger is just some enormous increase in the amount of vulnerabilities, in the amount of breaches, in the financial damage that's done from ransomware on schools, hospitals, not to mention banks', and 'this is about a moment of danger where if we respond to it correctly, and I think we started to take the first steps, then we can have a better world on the other side'; most Mythos-discovered vulnerabilities haven't been publicly disclosed because they remain unpatched and 'the bad guys will exploit' them; Amodei appeared alongside JPMorgan Chase CEO Jamie Dimon at Anthropic's New York financial services event, signaling Anthropic's lead in the enterprise AI market; Anthropic on the same day unveiled 10 banking and back-office AI agent templates and a unified Microsoft Office integration.

Fortune analyzes Anthropic's accelerating push into Wall Street with Moody's, Microsoft 365, and Jamie Dimon's endorsement — at an invite-only New York financial services briefing on 5/5, Anthropic launched 10 ready-to-run agent templates targeting the most labor-intensive workflows in banking, asset management, and insurance: pitchbook construction, KYC file screening, credit memos, underwriting, month-end close, statement audits, and insurance claims; three ecosystem deepenings were also announced: (1) full Microsoft 365 integration (Excel, PowerPoint, and Word add-ins generally available that day; Outlook in beta), with Claude functioning as a single agent that carries context across all four Office applications; (2) Moody's embeds its full platform into Claude as a native app, enabling analysis of credit ratings and risk data for over 600 million companies; (3) Claude Opus 4.7 shows substantial gains on financial work; through Dimon's joint appearance, the 5/4 JV with Goldman/Blackstone/H&F, and Microsoft 365 integration, Anthropic is building the 'operating layer for Wall Street'.

Anthropic launches Claude financial services agent templates and Microsoft 365 integration — debuts 10 ready-to-run financial services agent templates: Pitch builder (pitchbook construction), Meeting preparer, Earnings reviewer, Model builder, Market researcher, Valuation reviewer, General ledger reconciler (including NAV calculations against books of record), Month-end closer (close checklists, journal entries, close reports), Statement auditor (consistency, completeness, and audit-readiness checks), and KYC screener (entity files and escalation packages); templates run as a Claude Cowork or Claude Code plugin alongside the analyst, or as a Claude Managed Agent autonomously on the Claude Platform for batched deal books or nightly schedules; Microsoft 365 add-ins ship in parallel: Excel, PowerPoint, and Word generally available, Outlook coming in beta, with Claude operating as a single agent that carries context across all four Office applications; Moody's embeds its full platform as a native Claude app for analyzing credit ratings and risk data on over 600 million companies; the launch event in New York featured JPMorgan Chase CEO Jamie Dimon alongside Anthropic founder and CEO Amodei.

Claude Code 2.1.128 — 30+ bug fixes and several new features: bare `/color` picks a random session color; `/mcp` shows tool count for connected servers and flags servers with 0 tools; `--plugin-dir` accepts .zip plugin archives; `--channels` works with console auth (managed orgs require `channelsEnabled: true`); `/model` picker consolidates duplicate Opus 4.7 entries with current Opus shown as 'Opus'; OpenTelemetry: subprocesses (Bash, hooks, MCP, LSP) no longer inherit `OTEL_*` environment variables, preventing OTEL-instrumented apps from picking up the CLI's OTLP endpoint; fixes `CLAUDE_CODE_SHELL_PREFIX` argument corruption for MCP stdio servers when set with arguments containing spaces or metacharacters; SDK hosts receive persistent suggestions for Bash permission prompts via `localSettings`, written to `.claude/settings.local.json`; fixes crash loop when piping large input (>10MB) via stdin, MCP tool results dropping images with structured content, `/rename` failures on resumed sessions, tab navigation in `/config` stranding focus, parallel shell tool calls canceling on read-only failures, vim NORMAL-mode Space-key behavior, `/plugin update` not detecting npm-sourced plugin versions, stale `installed_plugins.json` entries polluting PATH, sub-agent summaries repeatedly firing and excessive token cost on idle agents, and multiple terminal rendering and hyperlink issues. Skipped v2.1.127 (never released).

Bloomberg reports the EU is in talks with Anthropic to get banks tested for Mythos-discovered flaws — Eurogroup finance ministers convened to discuss 'no European government currently has access to Mythos', with the White House having spent the last several weeks blocking Anthropic's plan to expand Mythos access to roughly 70 additional organizations and no European bank on the launch list; Germany's central bank publicly called on the EU to demand access to Mythos, arguing European banks cannot realistically test their own infrastructure against threats an adversary armed with the model would be capable of mounting; banks across the eurozone of all sizes have voiced concern about Mythos access; Mythos was unveiled on 4/7 and can identify and in principle exploit zero-day vulnerabilities in every major operating system and web browser, finding nearly 300 vulnerabilities in Firefox alone.

Fortune analysis: Anthropic JV is a frontal challenge to the Big Three consulting industry — headline directly states 'Anthropic takes shot at consulting industry'; the analysis notes the global software-to-services spend ratio is 1:6 (a multitrillion-dollar consulting market), giving AI-native firms a disruption opportunity; cites Sequoia partner Julien Bek's April thesis that 'the world's next great company won't sell software at all, but outcomes' (legal services, financial analysis, insurance processing delivered by AI but billed like consulting), and frames this JV as 'that thesis, capitalized and staffed'; the new firm is a standalone entity with Anthropic engineers embedded, mirroring Palantir's forward-deployment model, combining implementation capability with ownership of the underlying model to undercut traditional consultants; Blackstone President Jon Gray says the goal is to break down 'one of the most significant bottlenecks to enterprise AI adoption — the scarcity of engineers who can implement frontier AI systems at speed'; Anthropic CFO Krishna Rao: 'Enterprise demand for Claude is significantly outpacing any single delivery model. This new firm brings additional operating capability to the ecosystem'; PE is the natural beachhead: 85% of buyers now factor AI-enabled finance capabilities into company valuations.

Anthropic launches a $1.5B AI enterprise services firm with Goldman Sachs, Blackstone, and Hellman & Friedman — the three anchor partners each contribute about $300M, Goldman adds $150M, with additional backing from Apollo Global Management, General Atlantic, Leonard Green, Singapore's GIC, and Sequoia Capital; the new firm (still unnamed) aims to embed Claude into the core operations of mid-size businesses, starting with PE-portfolio companies and expanding to healthcare, manufacturing, financial services, retail, and real estate; positioned not as a traditional consultancy but as a venture deploying engineers to redesign workflows; Goldman global head of asset and wealth management Marc Nachmann said 'There's a big shortage of people who know how to apply these tools into businesses and then transform them' — combining technology with business context for real implementation; comes as both Anthropic and OpenAI prepare for IPOs as soon as this fall.

Elevated errors on Claude Opus 4.7 — status.claude.com identified the issue and implemented a fix at 05-04 14:07 UTC, resolved at 14:33 UTC, lasting approximately 26 minutes.

Axios comparative report: OpenAI announces a parallel $10B JV 'The Deployment Company' the same day, mirroring Anthropic's PE strategy — investors include TPG (anchor), Brookfield, Advent International, Bain Capital, Goanna Capital, and 14 others (19 total), with the PE consortium contributing roughly $4B over 5 years; OpenAI guarantees PE backers a 17.5% annual return over 5 years and adopts a Palantir-style forward-deployed engineer model; strategic intent matches Anthropic's JV — solving the AI-adoption choke point of 'how do enterprises use these tools in an ROI-positive way', with PE supplying portfolio companies as a built-in distribution channel focused on mid-sized firms; Anthropic's head of product for financial services Nicholas Lin told Axios 'There's a big gap between what AI can do today and the value the market is truly getting from it', noting the JV will help Anthropic scale customer support and develop deployment templates that copy across firms; demand is currently strongest for coding tools, expanding to finance and healthcare.

Elevated errors on Claude Opus 4.5 and Sonnet 4.5 — status.claude.com began investigating at 05-04 13:59 UTC, identified at 14:08 UTC, entered monitoring at 14:27 UTC, and resolved at 14:45 UTC, lasting approximately 46 minutes.

Anthropic, Blackstone, Hellman & Friedman, and Goldman Sachs announce a new AI-native enterprise services company — a standalone entity that embeds Anthropic Applied AI engineers directly inside customers to design and maintain Claude deployments, identify highest-impact use cases, and build custom solutions; total committed capital $1.5B with Anthropic, Blackstone, and Hellman & Friedman each anchoring at $300M and Goldman Sachs at $150M, plus General Atlantic, Leonard Green, Apollo Global Management, GIC, and Sequoia Capital filling out the consortium; the partners will use their own portfolio companies as the initial proving ground before targeting mid-sized companies, especially in PE-owned healthcare, manufacturing, financial services, retail, and real estate; OpenAI is reportedly pursuing a near-identical structure with TPG and Bain Capital; Anthropic is eyeing a public listing as soon as this year.

Elevated errors on Claude Opus 4.5 — status.claude.com began investigating at 05-04 08:09 UTC, identified at 08:19 UTC, continued working on the fix at 09:14 UTC, entered monitoring at 09:23 UTC, and resolved at 09:49 UTC, lasting approximately 1 hour 40 minutes.

The Department of War announces classified-network AI deployment agreements with eight technology companies — SpaceX, OpenAI, Google, NVIDIA, Microsoft, AWS, Reflection, and Oracle — pointedly excluding Anthropic; the exclusion stems from a supply-chain risk designation Defense Secretary Hegseth formalized in March after Anthropic refused to authorize Pentagon use of Claude for 'all lawful purposes' (Anthropic's stance: the language could enable domestic mass surveillance or fully autonomous weapons); during Congressional testimony Hegseth called Anthropic founder and CEO Amodei an 'ideological lunatic' and on X declared 'effective immediately, no contractor, supplier, or partner' doing business with the Pentagon may engage in any commercial activity with Anthropic; Anthropic has filed two suits in San Francisco and Washington, D.C., asking federal judges to overturn the order, with both cases ongoing; tensions eased somewhat after Trump Chief of Staff Wiles and senior officials met Amodei at the White House on 4/17, and Trump told CNBC a deal was 'possible'.

Fed Vice Chair for Supervision Bowman, in a speech at the FSOC AI Series Roundtable (theme: cybersecurity and risk management, held in Washington 4/27), used Anthropic's Mythos as an example to argue AI supervision must adapt dynamically — directly citing Mythos as evidence of the technology's 'dynamic nature' and noting its dual-use character: it lets firms patch self-identified vulnerabilities to enhance cybersecurity, but if used maliciously it could identify and exploit weaknesses; mentions that Treasury Secretary Bessent and Fed Chair Powell already convened major banks to discuss Mythos cybersecurity implications; on 4/17 the Fed/OCC/FDIC issued SR letter 26-2 narrowing existing model-risk-management guidance to traditional models and basic AI, leaving generative and agentic AI (including Mythos) outside the framework while regulators develop a new one.

On CNBC's 'Squawk Box', Pentagon CTO Emil Michael draws an explicit distinction — Anthropic itself remains on the supply-chain-risk blacklist, but its Mythos model 'is a separate national security moment'; direct quote from Michael: 'the Mythos issue that's being dealt with government-wide, not just at Department [of] War, is a separate national security moment where we have to make sure that our networks are hardened up, because that model has capabilities that are particular to finding cyber vulnerabilities and patching them'; he also stresses 'whatever guardrails, whatever principles they want to develop against has to be consistent with our values, our mandate, our restrictions even'; the interview airs the same day the Department of War excludes Anthropic from its eight-vendor classified-network AI list, echoing the softening signal Trump sent CNBC after Amodei's 4/17 White House meeting that a deal was 'possible'.

Claude Code 2.1.126 — Model picker now lists models from the gateway's `/v1/models` endpoint (when `ANTHROPIC_BASE_URL` points to an Anthropic-compatible gateway); adds `claude project purge [path]` to delete all Claude Code project state (transcripts, tasks, file history, config), with `--dry-run` / `-y/--yes` / `-i/--interactive` / `--all` flags; `claude auth login` now accepts pasting the OAuth code directly into the terminal for environments where browser callback cannot reach localhost (WSL2, SSH, containers); OpenTelemetry `claude_code.skill_activated` event adds `invocation_trigger` attribute (`user-slash` / `claude-proactive` / `nested-skill`); `--dangerously-skip-permissions` now bypasses prompts for writes to `.claude/`, `.git/`, `.vscode/`, shell config files, etc.; improved PowerShell 7 detection on Windows (Microsoft Store / MSI / .NET global tool), and PowerShell becomes the primary shell on Windows when enabled, replacing the default Bash; fixes auto-downscaling of images larger than 2000px, removal of oversized images from history, OAuth timeout on slow connections and IPv6-only devcontainers, stream idle timeout after Mac sleep and during long thinking pauses, Japanese/Korean/Chinese character rendering on Windows, `Ctrl+L` clearing prompt input, clipboard writes exposing content to EDR/SIEM telemetry, deferred tools unavailable in skills with `context: fork`, and several other issues; security fix: `allowManagedDomainsOnly` / `allowManagedReadPathsOnly` were ignored when a higher-priority managed-settings source lacked a `sandbox` block. v2.1.124 and v2.1.125 were skipped (never released).

Implicator.ai analysis: Claude Security public beta is Anthropic's strategic detour around Mythos access restrictions — the White House blocked Anthropic's plan to expand Mythos access to roughly 70 organizations, citing security and compute concerns; Claude Security gives Enterprise customers a supervised vulnerability-discovery path built on the safer Opus 4.7, sidestepping the federal review of Mythos; via service partners (Deloitte, Accenture, PwC), it reaches enterprise security business and converts revenue without depending on Mythos authorization; UK AI Security Institute scored Opus 4.7 at 48.6% on expert cyber tasks, behind GPT-5.5 (71.4%) and Mythos Preview (68.6%), but testing scenarios lacked active defenders and defensive tooling, limiting real-world applicability.

Anthropic Claude Security public beta — a code vulnerability scanning tool powered by Opus 4.7 with the model 'reasoning about code like a security researcher' by tracing component interactions and data flows across files (not just pattern matching); scans entire repos or specific directories/branches with each finding including confidence rating, severity, impact analysis, and reproduction steps, then generates targeted patch instructions that users can open in Claude Code on the Web to apply the fix in context; supports scheduled scans, CSV/Markdown export, Slack/Jira webhooks, and finding dismissals with documented audit reasons; Enterprise customers can enable it from the admin console, with Team and Max coming soon; technology partners: CrowdStrike, Microsoft Security, Palo Alto Networks, SentinelOne, TrendAI, Wiz; services partners: Accenture, BCG, Deloitte, Infosys, PwC.

Bloomberg via Yahoo Finance reports: NSA tests Anthropic Mythos to find security flaws in Microsoft software — NSA staff including members of its cybersecurity directorate tested the tool to identify security flaws in Microsoft programs and other widely used software, were impressed by its speed and efficiency, and compared the results against the agency's existing tools and processes; the testing comes amid the dispute between Anthropic and the Trump administration (Pentagon has labeled Anthropic a supply-chain threat, and Defense Secretary Hegseth announced in February that DoD would transition off Anthropic services within six months); neither Anthropic nor Microsoft offered substantive public comment on the testing.

Anthropic publishes an official post-mortem on the recent Claude Code quality regression -- confirming users were not imagining the drop in intelligence over the past month. Three product-layer changes were responsible: (1) On Mar 4, default reasoning effort was lowered from `high` to `medium` to reduce UI latency (reverted Apr 7); (2) On Mar 26, a caching optimization that cleared older thinking from sessions idle for over an hour had a bug causing it to trigger every turn instead of just once (fixed Apr 10); (3) On Apr 16, system prompt instructions were added to limit verbosity (under 25 words between tool calls, under 100 words for final responses), which hurt Opus 4.7 coding evaluations (reverted Apr 20). Affected Sonnet 4.6 / Opus 4.6 / Opus 4.7. Anthropic also reset all subscribers' 5-hour and weekly usage quotas as compensation.

Memory for Claude Managed Agents is now in public beta. Memory stores allow agents to persist information across sessions; each store is a workspace-scoped collection of text documents mounted as a directory under `/mnt/memory/` inside the session container, readable and writable using the standard agent toolset. Every mutation creates an immutable memory version for audit and rollback (retained 30 days). A maximum of 8 memory stores can be attached per session with `read_write` or `read_only` access controls. Requires the `managed-agents-2026-04-01` beta header.

Claude Code 2.1.118 -- Adds vim visual mode (`v` for character selection, `V` for line selection, with operators and visual feedback); merges `/cost` and `/stats` into `/usage` (the original commands remain as typing shortcuts that open the relevant tab); create or switch named custom themes from `/theme`, or hand-edit JSON in `~/.claude/themes/`; plugins can ship themes via a `themes/` directory; Hooks gain `type: "mcp_tool"` to invoke MCP tools directly; adds `DISABLE_UPDATES` env var (stricter than `DISABLE_AUTOUPDATER`, also blocks manual `claude update`); Auto mode lists support `"$defaults"` token to append custom rules on top of the built-in list; fixes multiple MCP OAuth issues (token responses missing `expires_in` forcing re-auth every hour, step-up authorization silently refreshing instead of prompting, cross-process lock contention, macOS keychain race overwriting freshly-refreshed tokens with misleading `/login` prompts, refresh failing when the server revokes a token early); fixes Linux/Windows credential save crash corrupting `~/.claude/.credentials.json`, `/fork` writing the full parent conversation per fork, Alt+K / Alt+X freezing keyboard input, and many more.

Claude.ai MCP applications unavailable -- status.claude.com identified the issue at 04-23 00:41 UTC and resolved it at 02:09 UTC; duration approximately 1 hour 28 minutes; affected claude.ai, platform.claude.com, API, Claude Code, Cowork, and Claude for Government.

Anthropic briefly A/B tested removing Claude Code from the Pro plan for 2% of new Pro subscribers -- the pricing page temporarily showed Pro ($20/month) without Claude Code, but following strong community backlash, it was restored within hours. Anthropic acknowledged a surge in usage and said the plan structure is under review.

Claude Code 2.1.117 -- Adds `CLAUDE_CODE_FORK_SUBAGENT=1` to enable forked subagents on external builds; `/model` selections persist across restarts (even when the project pins a different model); `/resume` now offers to summarize stale, large sessions before re-reading; local and claude.ai MCP servers connect concurrently for faster startup; macOS/Linux native builds replace `Glob`/`Grep` with embedded `bfs`/`ugrep` invoked through the Bash tool (Windows and npm installs unchanged); default effort for Pro/Max subscribers on Opus 4.6 / Sonnet 4.6 raised from `medium` to `high`; fixes OAuth tokens expiring mid-session and forcing manual `/login`, WebFetch hanging on very large HTML pages, and Opus 4.7 `/context` percentages computed against 200K instead of the actual 1M window.

Bloomberg reports a small number of unauthorized users bypassed the invite-only restrictions to access Anthropic's Mythos model research preview; Anthropic confirmed the incident occurred and is investigating while strengthening access-control mechanisms.

On CNBC, US President Trump publicly described Anthropic as 'getting better' and said an AI-use agreement with the Department of War is 'possible'. The Pentagon blacklist dispute has visibly eased since Anthropic founder and CEO Amodei's White House meeting with Chief of Staff Wiles and Treasury Secretary Bessent to discuss the Mythos model.

Claude Code 2.1.116 -- /resume now 67% faster on large sessions (40MB+), MCP startup accelerated, improved terminal scrolling in VS Code/Cursor/Windsurf, thinking spinner shows inline progress hints ('still thinking' → 'almost done'); fixes Devanagari character rendering, sandbox safe path bypass, and several other issues.

Claude.ai / API file upload errors -- status.claude.com began investigating at 13:31 UTC on 04-20 and resolved at 14:21 UTC; duration approximately 50 minutes; affected a subset of Claude.ai and Claude API file upload requests.

Anthropic officially announces expanded compute partnership with Amazon -- attributing the move to 'unprecedented consumer growth' straining reliability (run-rate revenue grew from $9B to $30B). Up to 5GW of capacity on AWS over 10 years; over 1 million Trainium2 chips currently running, new Trainium2 capacity launching Q2 2026, Trainium3 adding roughly 1GW by year-end, with the option for future Trainium4.

Bloomberg covers the financial terms of the Amazon investment -- Amazon adds $5B (cumulative $13B; milestone clauses allow expansion up to $25B); Anthropic commits to spending over $100B on AWS over 10 years; round valuation: $380B.
