Anthropic

Anthropic has launched OSS Scanner, an opt-in service that gives open-source projects periodic vulnerability scans at no cost, run by its strongest models including Claude Mythos. Reports are fully model-generated with no human review or triage, so Anthropic warns some may be incorrect or invalid.

Anthropic launched two beta features for Claude: Dashboards, which builds auto-updating dashboards from connected data sources, and Motion, which generates animated explainer videos exportable as MP4. Docs, Slides and Design leave beta and now work on every plan, including free accounts.

Claude Haiku 5.5 is available on Amazon Bedrock and Claude Platform on AWS. According to Anthropic, it is the fastest and most efficient model in the Claude 5.5 family and costs around 75% less than Claude Haiku 4.5 for most tasks. It is the first Haiku model with effort controls.

Anthropic released Claude Haiku 5.5 on October 7, 2026. The company claims it costs around 75% less to run than Haiku 4.5 and is its fastest model to date. Anthropic also halved Claude Sonnet 5.5's cache read pricing and added a monthly API credit for Max and Team subscribers.

Anthropic's Python SDK v1.12.0, dated 2026-10-07, adds the claude-haiku-5-5 model identifier and typed tool calls for the computer and browser toolsets. It also adds lifecycle fields to /v1/models and several admin API changes. The release notes give no pricing, context window, or benchmark data for the new model.

Anthropic is expanding its Cyber Verification Program (CVP) to a much larger pool of vetted security professionals, giving them access to Claude's most powerful models with reduced safety filters. Access is split into three tiers: Defense, Red Team, and Specialized. Anthropic claims partners in its predecessor program, Project Glasswing, found at least 129,000 confirmed vulnerabilities between April and July 2026.

Cline CLI v3.0.69 raises the default MCP server startup timeout from 3 seconds to 10 seconds. On Windows, servers launched via npx or uvx were being silently dropped. The release also fixes Claude requests through custom Anthropic base URLs, reasoning-level mismatches, and a broken `cline config --json` command.

Anthropic has released the Claude for Google Workspace add-on in public beta, placing a Claude sidebar inside Google Docs, Sheets, and Slides. It is available to all paid Claude users through the Google Workspace Marketplace, and includes an "ask before edits" preview mode.

Claude Opus 5.5 and Claude Sonnet 5.5 are available on Amazon Bedrock in AWS GovCloud (US) Regions. AWS published a setup guide for running Anthropic's Claude Code against them for regulated workloads, including ITAR. Pricing, context window and benchmark figures were not disclosed.

Anthropic released Mods for Claude Code, a plugin system built on JavaScript and TypeScript functions that hook into events such as tool calls, user prompts and UI rendering. Mods are not sandboxed and run with the user's permissions. They work in the CLI, the desktop app and, partly, the VS Code extension.

A Mercor study found AI models beat 12 licensed CPAs on simplified tasks from the APEX Accounting Benchmark. On the full 160-task benchmark, the top model, Claude Opus 5.5, meets 61.8% of grading criteria, and no model fully solved almost 60% of tasks.

Pi, the minimalist agent harness now under Earendil, has reached version 1.0. A companion release, Pi Durable, ports it to TypeScript and externalizes all stateful components so agents can resume after crashes. Pricing and licensing were not disclosed in the source.

Marketing firm Graphite identified 13,000 phrases that appear at least twice as often in AI-generated writing as in human writing. Claude Opus 5.5 uses "this matters" 116 times more than humans, while OpenAI's Astra favors "corrective framing" more than 100 times as often. Em-dash use has collapsed across frontier models, but total tells are holding steady, according to Graphite.

Anthropic is now offering Claude for Government to US federal and state agencies. The platform has been in open beta since July and runs in a FedRAMP High environment. The launch comes as the company's legal fight with the Pentagon continues.

Cline's v4.1.22 release adds two new model providers, refreshes default models across more than a dozen gateways including a switch to GPT-6.1 Sol, and fixes bugs in Anthropic content-filter handling, Bedrock inference profiles, and reasoning token accounting.

Anthropic's Frontier Red Team reports that Zhipu AI's GLM-5.3 achieved full control flow hijacks in 4% of binary exploitation trials, versus 6% for Claude Mythos Preview. Predecessor models Claude Opus 4.6 and GLM-5.2 scored zero, marking what Anthropic calls a crossed threshold in offensive cyber capability.

Anthropic's Claude Sonnet 5.5 is now available on Amazon Bedrock and Claude Platform on AWS, positioned as a faster, lower-cost model for well-scoped coding and document tasks. It pairs with the recently released Claude Opus 5.5, which handles higher-judgment work.

Anthropic's anthropic-sdk-python v1.9.0 release adds a reference to an unannounced 'claude-sonnet-5-5' model ID, a new between_tools thinking type, and the ability to run tool calls while a reply streams. No pricing, context window, or benchmark data for the model has been disclosed.

Anthropic has released Sonnet 5.5, the latest version of its mid-tier Claude model, claiming 30% faster performance and significantly lower token costs than its predecessor. The company says the model now outperforms Opus 5.5 on agentic coding tasks and carries cyber capabilities comparable to Opus 5.

Anthropic announced that a 950-agent Claude system in its molecular biology lab flagged a gene-repeat pattern near a known enzyme after 21 hours, calling it reminiscent of the discovery path that led to CRISPR. Biologists, including one who says his team found the same pattern earlier, dispute that this constitutes a genuine scientific discovery.
