# Anduril in talks to raise at a ~ valuation
- Anthropic published new context-engineering guidance for Claude Opus 5 and Fable 5, reporting its Claude Code team removed more than 80% of the CLI’s system prompt with no measurable regression on coding evals — favoring minimal instructions and richer reference material over rigid rules.
- A companion /doctor command helps developers right-size their own configurations.
# Anthropic Launches Claude Opus 5, a Cheaper Agent-Focused Flagship
# Anthropic launches Claude Opus 5 at roughly half the cost of rival flagships
# Anthropic launches Claude Opus 5, its most capable and most aligned model
- Anthropic released Claude Opus 5 at $5 / $25 per million input/output tokens — half the cost of Fable 5 — while winning five of nine head-to-head benchmarks and scoring 43.3% on Frontier-Bench v0.1 (vs Fable 5’s 33.7%).
- Anthropic says cyber-safety classifiers intervene ~85% less often and calls it its most-aligned model to date; it is now the default across Claude Max, API, Claude Code and Cowork.
- Apple published LEAD, or Lookahead-Enhanced Atomic Decomposition, a method aimed at reducing failures in long-horizon reasoning.
- The research argues that extreme decomposition can create a no-recovery bottleneck, where errors on a few hard steps become irreversible.
- The work is relevant for agentic systems because it targets a core reliability problem: how to break work into steps without making early mistakes unrecoverable.
# AWS moves Q Business, Kendra, and Bedrock Agents to maintenance mode
- TechCrunch reports that Bluesky's AI assistant Attie expanded into a tool for asking questions about news, trends, and conversations across Bluesky and other AT Protocol applications.
- The move shows how social networks are turning public conversation graphs into queryable research surfaces.
- The business value will depend on whether platforms can provide useful summarization without creating privacy, manipulation, or source-attribution problems.
