A daily digest of everything new about Claude and Anthropic

Grants of up to $50,000 in Claude usage credits are being offered to researchers accelerating cures for rare diseases. This initiative marks the first focused call within the AI for Science program, which supports scientists using Claude to speed up discovery.

A developer rebuilt a memory system for Claude Code using the best features from Hermes Agent, which gained 211,000 GitHub stars in five months after launching in February. The new system enables Claude to recall decisions made up to six months prior and cite the specific conversation where they originated, all while functioning on an existing Claude subscription without requiring external servers or additional services.

Anthropic’s Claude Fable 5 access plans change from July 20: Here’s what’s new The Indian Express [truncated: Google News RSS provides only a snippet, not full article

Anthropic extends Claude Code's 50% weekly limit increase through August

A user experienced recurring automatic conversation compactions while working on a book project with Claude, with the compaction occurring approximately every 5 hours and happening three times across three sessions. Each compaction consumed substantial token usage, pushing the session to 84% capacity within minutes and preventing significant progress on the project before hitting usage limits.

OpenAI launched GPT-5.6 and merged ChatGPT with Codex into a single app featuring three model tiers (Sol, Terra, and Luna) and a new Work tab that enables autonomous task execution over extended periods. The update includes enhanced computer interaction capabilities and an integrated browser for file access and account login. Competing models from Meta, xAI, and other companies were released this week, with most emphasizing significant cost reductions rather than performance advantages over OpenAI and Anthropic's offerings.

The Claude SDK's SessionStore adapter interface enables session transcripts to be mirrored from local JSONL files to external backends such as S3, Redis, or databases, allowing sessions created on one host to be resumed on another while improving durability and compliance. The SessionStore interface requires two core methods—append for writing entries and load for reading them—plus optional methods for operations like listing sessions and managing subagents. Reference implementations for S3, Redis, and Postgres are available in the SDK repository, and both TypeScript and Python SDKs include conformance test suites to validate custom adapter implementations.

Anthropic announced a $10 million CAD commitment to Canadian AI research institutions, including partnerships with the Alberta Machine Intelligence Institute, Mila, the Vector Institute, and universities such as the University of Toronto and University of Saskatchewan to fund research in beneficial and responsible AI applications. Data from the Anthropic Economic Index reveals that Canadians use Claude at more than four times the rate predicted by population, ranking eighth globally in Claude.ai usage and second by per-capita adoption among the top 10 countries.

An AI assistant's personality traits such as wordiness, politeness, and agreeability result from deliberate training rather than randomness. These behaviors are shaped through two distinct stages: pretraining, which develops a document completer, and fine-tuning, which transforms the model into an assistant. Both stages leave measurable traces on the final system.

alphaXiv is a search tool offering fast retrieval and full-text access to millions of arXiv preprints through keyword and embedding search capabilities. The platform supports conducting literature reviews, posing grounded research queries with technical specificity, and implementing methodologies from academic papers in various software codebases.

Claude Opus 4.7 can audit large folders of visual assets against brand guidelines to identify violations including off-brand colors, outdated logos, and missing legal copy, providing categorized lists of violations with confidence ratings. The model reads images at higher resolution than previous versions, enabling detection of small details like specific hex codes and legal text, and processes hundreds of assets at once through Claude Cowork. Violations can be grouped by type and priority, integrated into project management systems like Asana, or scheduled for recurring audits with results posted to Slack.

Claude Code is an agentic coding environment that enables autonomous problem-solving by reading files, running commands, and implementing solutions rather than simply responding to questions. The primary constraint in using Claude Code effectively is managing the context window, which fills rapidly during coding sessions and causes performance degradation as it becomes full. Best practices for maximizing Claude Code's effectiveness include providing clear verification criteria, exploring and planning before implementation, offering specific contextual information in prompts, and establishing persistent instructions through a CLAUDE.md configuration file.

# Anthropic Courses Overview Anthropic offers a comprehensive suite of structured learning paths covering AI fundamentals and Claude development, including specialized tracks for agents (subagents, Claude Cowork, agent skills), the Claude API, and Model Context Protocol (MCP) at both introductory and advanced levels. Additionally, learners can find courses on AI fluency for different audiences (general and nonprofit-focused) plus deployment guides for Claude with major cloud providers (AWS Bedrock, Google Vertex AI). These courses combine video lessons and assessments to help developers build practical AI collaboration and integration skills.

Anthropic Academy provides a comprehensive development guide covering Claude API tools, resources, and educational materials for building with various Claude models. The guide encompasses tutorials, courses, and documentation for implementing the Messages API, File APIs, tool use, vision capabilities, RAG systems, prompt caching, MCP integration, and Claude Code. Code samples and implementation guides are available through the Anthropic Cookbook and Quickstarts repository for common development workflows.
