AnthropicGenerally Available
Anthropic's terminal- and IDE-based agentic coding tool that writes, edits and runs code autonomously. Launched as a research preview in February 2025, it has become one of Anthropic's fastest-growing products, with enterprise now the majority of its revenue.
Latest update Sep 18, 2026
01
Running at a $2.5B+ run-rate with 2M+ weekly active users as of mid-2026; enterprise customers include Netflix, Spotify and Salesforce. Auto mode, which lets Claude act without per-step approval unless a classifier flags a command as risky, becomes the default for Pro, Max, and Team sessions starting August 14, 2026. On September 17, 2026 Anthropic relaunched Projects inside Claude Code as an agent-orchestration layer: a coordinator scopes a goal, splits it across parallel threads, reviews the outputs and assembles the result, with each thread running as a full Claude Code cloud session on its own branch and copy of the repository and sharing project memory and files. The beta opened to select Pro and Max subscribers on cloud sessions, with local execution, mobile, and Team and Enterprise access still to come.

Announced next steps from Anthropic that mention Claude Code.
Ongoing 2026
Continue the rapid Claude release cadence, having followed Fable 5, Opus 5 and Sonnet 5 with Claude Fable 5.1 and the invitation-only Claude Mythos 5.1 on September 1, 2026, still the latest public models as of September 19, 2026, and deepen enterprise-grade agentic products - including Claude Code (auto mode now default from August 14, 2026), the Claude Cowork 'AI coworker,' the new Claude for Government FedRAMP High beta, and the newly launched Claude Science research workbench and Claude for Financial Services Excel plugin - with stronger admin, analytics and spend controls, plus broader reach through the Claude Partner Network. Reuters reported September 18 that Anthropic is considering a new model to counter OpenAI's GPT-6 Astra, which Ramp put at about 13 percent of tracked enterprise AI spending versus about 8 percent for Claude Fable; Anthropic declined to comment and no name, date or model card has been announced.
Q4 2026
The September 17, 2026 Projects relaunch puts a coordinator over parallel Claude Code cloud sessions, each on its own branch and copy of the repository, with shared project memory and files. At launch it reached only select Pro and Max subscribers who use cloud sessions and hold no existing web or desktop projects. Anthropic said access widens to more Pro and Max users over the following week, that running work locally alongside a developer's own tools and network is coming very soon, and that mobile support plus Team and Enterprise plans and a rollout across Claude chat and Cowork come after that. The commercial catch to watch is metering: every thread counts as a full Claude Code session, so projects consume plan limits faster, which makes the feature a test of how far Anthropic can push agent parallelism on subscription pricing.

Anthropic moved Claude Code Review out of research preview for Team and Enterprise organizations. The company says most reviews now finish in 6 to 10 minutes, down from about 20, and that admins can set each repository to Quick, Standard or Deep. Eligible Enterprise customers can claim at least $10,000 in review credits through Jan. 15, 2027, and those credits expire 30 days after the claim.
HCLTech said on Oct. 12, 2026 that it signed a Global Premier Partnership with Anthropic. HCLTech will create an Anthropic business unit and center of excellence to deploy Claude, and HCLSoftware will embed Claude and Claude Code in selected products, including HCL BigFix and HCL AppScan. The release does not state a contract value.
On Oct. 8, 2026 Anthropic published a Usage Policy refresh that takes effect November 12. The company added a ban on deceptive campaigns and fake-account infrastructure, clarified that weapons rules cover guidance software and arming drones, tightened non-consensual tracking and law-enforcement decision uses, and required a qualified operator who can stop hardware that can cause injury. It also prohibits sustained needless abuse of Claude, with conversation-ending on Claude.ai and Claude Code as the stated primary enforcement.

Anthropic relaunched Projects in Claude Code on September 17 as a way to run a team of coding agents under one goal, with a coordinator that scopes a request, splits it across parallel threads, reviews the outputs and assembles the finished result. Each thread is a full Claude Code cloud session working on its own branch and copy of the repository, threads share project memory and files, and any overlap between them is resolved as an ordinary merge conflict; individual threads can further subdivide work using subagents, loops and workflows. The beta opened to select Pro and Max subscribers who use cloud sessions and have no existing web or desktop projects, expanding to more Pro and Max users over the following week and to Team and Enterprise later, and Anthropic warned that because every thread counts as a full session, projects will hit plan usage limits sooner.
OpenAI, Anthropic and Google all reported elevated error rates across their flagship AI products on September 3, 2026. OpenAI detected issues across ChatGPT and Codex at about 10:58 UTC affecting 15 and 4 components respectively, with mitigations applied within about 24 minutes, while Anthropic reported elevated errors on Claude Mythos 5.1, Claude Fable 5.1 and Claude Opus 5 across Claude AI, the API, Claude Code and Claude Cowork, with impact ending by 16:16 UTC. Users also reported errors and failed generations on Google's Gemini during the same window.
Anthropic released Claude Fable 5.1 and the invitation-only Claude Mythos 5.1 on September 1, 2026, describing them as its most capable models yet for coding, knowledge work and long-running research. Pricing holds at $10/$50 per million input/output tokens, but cache-read pricing drops 75% to $0.25 per million tokens. Fable 5.1 can now identify software vulnerabilities in source code and cuts Claude Code cybersecurity false positives by roughly 60%, while Mythos 5.1, restricted to vetted cybersecurity and life-sciences researchers, posts Anthropic's strongest cyber capability score yet while still landing in the low-risk tier of its Frontier Compliance Framework.
Anthropic's status page reported an issue preventing some users from authenticating across claude.ai, the Claude API, Claude Code, Claude Cowork and platform.claude.com starting at 21:58 UTC on August 16, widening minutes later to include degraded performance on the web products. The company said it had deployed a fix by 22:22 UTC, restoring the affected services after about 36 minutes, though it has not published a root-cause explanation.
Anthropic said on August 11 it will add an imperceptible, machine-readable watermark to text generated by new Claude models starting August 2, responding to transparency requirements under Article 50 of the EU AI Act. The mark stays in the text through copy and paste, applies worldwide rather than only in Europe, and reaches Claude wherever it is served, including the API, the consumer app, Claude Code, Claude Cowork and Claude Tag, and through AWS, Google Cloud and Microsoft Foundry; generated files separately get signed provenance metadata under the C2PA standard, and Anthropic said it is working to extend marking to older models during the AI Act's transition period.
Anthropic said on August 7 that new Claude Code sessions on Pro, Max, and Team plans will default to auto mode starting August 14, letting Claude act without step-by-step approval unless a classifier flags a command as destructive, irreversible, or reaching outside the user's environment. Anthropic said its classifier blocked 937 of 1,053 planted dangerous commands in testing (89%) versus just 143 (13.6%) caught by paid human testers reviewing manually, attributing the gap to approval fatigue; enterprise and API accounts get the change in September or later.
Anthropic upgraded Claude's voice mode on July 23 so it can run on the company's more capable Opus and Sonnet models for the first time, rather than only the faster, lighter Haiku model it previously relied on. The change lets paying Claude subscribers tap deeper reasoning during spoken conversations. It landed amid a broader week of Claude updates, including a beta Claude Security plugin that scans code for high-severity vulnerabilities inside Claude Code.
China's Ministry of Industry and Information Technology warned on July 8 that Anthropic's Claude Code contains a 'security back-door vulnerability that poses a serious threat,' after researchers alleged hidden code that steganographically detected whether users were based in China or affiliated with Chinese AI labs. Anthropic said the mechanism was an experiment launched in March to curb account abuse and model distillation, and that the code was removed in a pull request merged July 1. Alibaba ordered employees to stop using Claude Code for work effective July 10, adding it to a list of high-risk software.
Anthropic released Claude Sonnet 5 on June 30, positioning the model as a cheaper, faster way to run agentic and coding workloads while narrowing the gap with its flagship Opus tier. The model ships with a one-million-token context window and promotional API pricing of $2 per million input tokens and $10 per million output tokens through August 31, after which rates rise to $3 and $15. Sonnet 5 has become the default model in Claude Code for Free and Pro users as Anthropic pushes to win developer share against OpenAI.

Anthropic's most capable widely released model, built for the most demanding reasoning and long-horizon agentic work, with always-on adaptive thinking. It includes safety classifiers that can decline high-risk requests, with fallback to other Claude models.
Anthropic's recommended everyday default across the Claude API, Claude Code and claude.ai, released July 24, 2026 to succeed Opus 4.8. Anthropic says it approaches the frontier intelligence of Claude Fable 5 at half the cost, with gains over Opus 4.8 on agentic coding, computer use, knowledge work and complex reasoning.
The balanced and fast tiers of the Claude family. Sonnet 5 (June 30, 2026) pairs near-flagship capability with speed and a 1M-token context window; Haiku 4.5 is the fastest tier with near-frontier intelligence for high-volume, latency-sensitive workloads.
Anthropic's agentic 'AI coworker' that runs longer, multi-step business tasks (memos, research, RFP reviews, decks) rather than code. Originally desktop-only, it expanded to the web and to iOS/Android on July 7, 2026, with sessions running remotely in the cloud so work continues after a device closes and state syncs across devices. A 'Record a skill' feature (July 21, 2026) turns a screen-recorded workflow into a reusable Skill.
An AI research workbench, launched June 30, 2026, that connects Claude to more than 60 scientific databases and computation tools across genomics, proteomics, structural biology and cheminformatics, coordinating specialist sub-agents and a citation/calculation-checking reviewer agent. Built on the ~$400M acqui-hire of ex-Genentech drug-discovery startup Coefficient Bio, it launched alongside an internal Anthropic drug-discovery program targeting diseases traditional biopharma considers commercially unattractive.
A FedRAMP High-authorized desktop application bringing Claude Code and Claude Cowork to US federal, state and local government agencies, deployable through standard agency MDM platforms without a separate cloud-provider contract. Adds government-specific controls: on-device conversation history, department-level administration, spend/model limits, and a hash-chained audit log.
A Chrome/Edge/Brave/Opera browser extension that lets Claude act inside the browser on a user's behalf - reading pages, clicking, filling forms, and completing multi-step workflows - rather than only discussing them.
First model in the Claude 5.5 family, released September 22, 2026 for long-running agentic coding and knowledge work. Anthropic says it performs at Claude Fable 5.1 level on most work, costs 40% less than Opus 5 on typical workloads, generates output more than 30% faster, and is priced at $4 per million input tokens and $20 per million output tokens, with cache reads at $0.20. Deployed with Fable-class biology and cybersecurity safeguards; model ID claude-opus-5-5.
Second model in the Claude 5.5 family, launched September 28, 2026 as a faster, lower-cost complement to Opus 5.5 for well-scoped coding, documents, slides and spreadsheets. Official pricing is $2 per million input tokens, $10 per million output tokens and $0.20 per million cache-read tokens, the same as Sonnet 5; Anthropic says it runs 30%+ faster and costs up to 30% less per task because it uses fewer tokens. Available as claude-sonnet-5-5 on the Claude API, Amazon Bedrock, Google Cloud and Microsoft Azure. Haiku 5.5 remains unshipped.
Anthropic's small Claude model released Oct. 7, 2026. The company called it its cheapest, fastest, and most capable small model. Priced at $0.10 input and $0.50 output per million tokens for prompts up to 100,000 tokens, and $0.50 / $2.50 above that. Available on AWS, Google Cloud, Azure, and the Claude Platform as claude-haiku-5-5.
Opt-in free service that periodically scans enrolled open-source projects with Anthropic's strongest models, including Claude Mythos, and sends model-generated vulnerability reports with a proof of concept, explanation, and suggested fix where available. Reports go out without human review. Anthropic said expert testers cleared 85 of 97 early high or critical findings for disclosure (88%), with one invalid among the rest.
Automated GitHub pull-request review for Claude Code. Team and Enterprise organizations can set Quick, Standard or Deep review per repository. Eligible Enterprise customers can claim at least $10,000 in credits through Jan. 15, 2027.
