- Claude Opus 4.8 Ships With Dynamic Workflows — Same $5/$25 API PriceAnthropic released Claude Opus 4.8 on May 28, 2026: dynamic workflows for Claude Code, effort controls, faster fast mode. API ID claude-opus-4-8 at unchanged $5/$25 per million tokens.
- Anthropic Files Confidential IPO at $965B Val, $47B Revenue Run RateAnthropic confidentially filed with the SEC on June 1, 2026 at $965B valuation and $47B annualized revenue — beating OpenAI to the IPO starting line as SpaceX roadshows this week.
OpenAI Codex crossed 5 million weekly active users on June 2, 2026 — up more than 6× since the desktop app launched in February — and shipped Sites (hosted interactive workspaces), Annotations for in-place edits, and six role-specific plugins bundling 62 apps and 110 skills as it chases white-collar workflows the same week Microsoft Build pushed Windows agent sandboxes.
Knowledge workers are now ~20% of Codex users and growing more than 3× faster than developers, per OpenAI's announcement.
What OpenAI Announced on June 2
Three product layers:
| Feature | What it does |
|---|---|
| Role plugins | Pre-built stacks for data analytics, creative, sales, product design, public equity, investment banking |
| Sites | Codex builds hosted interactive sites (dashboards, planners, review boards) shareable inside a workspace by URL |
| Annotations | Point at part of a doc, slide, sheet, or site — Codex edits only that selection |
Sites partners include Wix, Base44, Replit, Lovable, Figma, Webflow, Emergent — OpenAI plans a broader partner ecosystem.
Plugins pull from tools like Snowflake, Databricks, Salesforce, HubSpot, Tableau, Figma, FactSet, PitchBook, and more depending on role pack.
AWS Bedrock: Enterprise Inference Path
On June 1, 2026, OpenAI said frontier models and Codex are generally available on AWS Bedrock — letting teams run Codex-class workflows inside existing AWS IAM, VPC, and procurement rails instead of only OpenAI's first-party cloud.
For FinOps teams, compare LLM API Pricing across Bedrock vs direct OpenAI before locking annual commits.
Why This Lands Against Anthropic and Microsoft
Anthropic pushed enterprise agents in February and finance agents in May. OpenAI was slower on Codex plugins (March) but is now packaging vertical job templates — closer to Cowork territory.
Microsoft Build 2026 launched MXC kernel sandboxes and Windows Agent Framework the same week — see Microsoft MXC Agent Sandbox.
Developer takeaway: the fight moved from "who codes best" to "who owns the work product surface" — files, sites, and CRM records.
Security and Governance Notes
Sites are hosted by OpenAI (per VentureBeat reporting) — data residency and admin enable flags matter for regulated teams.
Plugin OAuth sprawl: 62 apps means 62 permission surfaces. Enterprise admins get workspace controls; startups often do not.

Key Takeaways
- June 2, 2026: Codex 5M+ weekly users; ~20% non-developers growing 3× faster than devs
- Sites + Annotations + 6 role plugins (62 apps, 110 skills) target analysts, sales, bankers, designers
- AWS Bedrock GA (June 1) for OpenAI frontier models + Codex in enterprise AWS estates
- Competes with Anthropic enterprise agents and Microsoft Build agent platform same week
- For developers: treat Codex as full-stack work surface, not CLI-only; model Bedrock egress and plugin OAuth scope
