# Closed labs ship new flagships and faster tiers

The closed labs kept shipping: GPT-6 Sol, Luna and 6.1 Sol, GPT-6 for all ChatGPT users plus an Ultrafast mode, Claude Haiku 5.5, Gemini 4 Argon and Meta's Muse Wonder. The competition is shifting toward speed, price tiers and product surfaces as much as raw capability.

## Evidence

- [Google releases Gemini 4 Argon globally](https://x.com/GoogleDeepMind/status/2110039274922131792) (Google DeepMind, release, 2026-10-13): Google's new frontier model for coding, finance, legal and security work. Cursor measures it on par with Opus 5.5 at $2/$10 per million tokens.
- [Meta introduces Muse Wonder and Muse Wonder Full](https://x.com/AIatMeta/status/2109691148943999167) (AI at Meta, release, 2026-10-12): Meta Superintelligence Labs' first frontier models, 14 months after its rebuild, aimed at personal and professional agentic tasks.
- [OpenAI rolls out Ultrafast mode for GPT-6.1 Sol](https://x.com/OpenAIDevs/status/2108262812489531498) (OpenAI Developers, release, 2026-10-08): Up to 8x faster than standard Sol across the API, Codex and ChatGPT Work, making near-top-tier models practical for interactive agent loops.
- [Anthropic releases Claude Haiku 5.5](https://x.com/claudeai/status/2107894039626277339) (Claude, release, 2026-10-07): About 75% cheaper to run than Haiku 4.5 and Anthropic's most capable small model, which changes the cost of high-volume agent subtasks.
- [GPT-6 and Intelligent UI roll out to everyone in ChatGPT](https://x.com/OpenAI/status/2107894997538525580) (OpenAI, news, 2026-10-07): Free users get GPT-6, and answers can now come back as generated interactive interfaces instead of only text.
- [GPT-6.1 Sol offers near-Astra intelligence at a fifth of the price](https://x.com/OpenAI/status/2104986129686741046) (OpenAI, release, 2026-09-29): OpenAI's new cost-efficient model narrows the gap between flagship quality and price, which matters most for agents that run all day.
- [OpenAI releases GPT-6 Sol and GPT-6 Luna](https://x.com/OpenAI/status/2102460975790137662) (OpenAI, release, 2026-09-22): Two faster, cheaper models carry most of GPT-6 Astra's strengths. They're aimed at running agents and high-volume work at lower cost.
