1. Anthropic’s Claude Opus 4.7 debuts with performance upgrade, rivals OpenAI’s GPT-5.4
Claude Opus 4.7 has surpassed GPT-5.4 (xhigh) and Sonnet 4.6 on the GDPval-AA benchmark:
The model can accept images up to 2,576 pixels on the long edge, 3x prior Claude models.
Uses an “updated tokenizer” that improves text processing but can map the same input to more tokens, Anthropic said.
It is less advanced in cyber capabilities than Mythos Preview, Anthropic said.
Opus 4.7 costs $5/$25 per million input/output tokens, in line with Opus 4.6, vs. GPT-5.4’s $2.5/$15 (<272K tokens) and GLM-5.1’s $1.4/$4.4.
Additionally, a White House memo said OMB is setting protections to allow agencies to use Anthropic’s Mythos

The memo doesn’t confirm timing or use details.
Coming weeks: tech and cybersecurity chiefs will receive more details, the memo said.
Separately, Anthropic has secured a new London office for 800 staff, days after OpenAI leased its first space in the city.
Most teams know AI can help. The hard part is building workflows that actually run reliably—connecting agents, automations, and LLMs into systems people use every day. You need someone who can design for the messy middle:
AI agent design and deployment
No-code and LLM workflow integration
Process and dashboard automation

3. Codex desktop app updated with computer control, browser, plugin support
Codex has expanded from coding into broader productivity workflows.
Computer control lets Codex operate the device autonomously.
Includes an in-app browser for automations and web tasks.
Can create agents to generate images, charts, and diagrams.
100+ plugins for integrations and expanded capabilities.
Available on macOS and Windows, though computer control is macOS-only.
