Is GPT-Rosalind (OpenAI) Down?

Meta's frontier model line from its Superintelligence Lab -- Muse Spark 1.1 (2026-07-09) adds substantially better coding, 1M-token multi-agent orchestration, and Meta's first paid developer API (Meta Model API, public preview)

**Claude Haiku 5.5 shipped on 2026-10-07 at $0.10 / $0.50 per 1M tokens for prompts up to 100K ($0.50 / $2.50 above) -- 90% below Haiku 4.5 on most requests -- with adjustable effort for the first time on a Haiku, and the same day Anthropic halved Sonnet 5.5 cache reads to $0.10 and added monthly API credits for Max ($100 or $200) and Team (up to $500 pooled).** **Anthropic expanded the Cyber Verification Program on 2026-10-06 into three access tiers (Defense, Red Team, Specialized) that unlock reduced cyber safeguards on Opus 5.5, Sonnet 5.5, Mythos 5.1 and future models for verified security teams -- closing the 'coming weeks' note Opus 5.5 shipped with; generally available Claude keeps its conservative cyber blocks.** **Two Claude 5.5 models in six days: Claude Opus 5.5 (2026-09-22) and Claude Sonnet 5.5 (2026-09-28).** Opus 5.5 performs at Fable 5.1 level on most work and costs 40% less than Opus 5 to run -- $4/$20 per 1M (down from $5/$25) with cache reads cut to $0.20 (from $0.50), fast mode at $8/$40 up to 2.5x speed, output 30%+ faster, and five-hour usage limits raised on Pro, Max, Team and seat-based Enterprise with a saveable rate-limit reset. Sonnet 5.5 keeps Sonnet 5's $2/$10 but needs far fewer tokens (up to 30% cheaper per task), runs 30%+ faster and jumps Terminal-Bench 4.0 from 10.3% to 70.6%. Both are 1M context, Jun 2026 cutoff, on the Claude Platform, Bedrock, Vertex and Foundry; Haiku 5.5 followed on 2026-10-07. Opus 5.5 launches with Fable-class cyber and bio safeguards (most cyber tasks fall back to Opus 4.8) and cannot run with thinking off.
