Anthropic

Anthropic ships its Mythos-class frontier generation as a pair: Claude Fable 5 — the Mythos-class model made safe for general use — and Claude Mythos 5, the same underlying model with safeguards lifted in some areas, restricted to Project Glasswing partners and select biology researchers. Fable 5 falls back to Claude Opus 4.8 for cybersecurity, biology/chemistry, and distillation queries (triggered in under 5% of sessions on average); Mythos-class models carry a 30-day data-retention policy. Priced at $10 per million input tokens and $50 per million output tokens.

Anthropic confidentially submitted a draft Form S-1 to the SEC, the first formal step toward an IPO and targeting a valuation near $965B. The filing follows its recent $65B Series H — which set that same $965B post-money mark — and lands alongside draft filings from OpenAI and SpaceX.

Anthropic officially launches Claude 4.8 Opus, its ultimate frontier model optimized for long-horizon autonomous system execution, repository-level software engineering, and multi-step complex logic.

Anthropic secures a historic $975 billion funding round backed by multi-national sovereign wealth entities to build gigawatt-scale data center infrastructure and self-sustaining energy arrays.

Anthropic releases Claude Opus 4.7 as its flagship model, delivering advanced multi-step tool use, elite coding, and top-tier logical reasoning.

Anthropic announces Claude Mythos under a gated private preview, focusing on defensive cybersecurity, automated exploit analysis, and mechanistic interpretability.

Anthropic launches Claude Opus 4.6, delivering optimization bumps for agentic reasoning and complex coding workloads.

Anthropic's revenue reached approximately $10 billion for fiscal 2025 — a roughly 10x increase year-over-year. Enterprise customers account for 70–80% of ARR. Cash burn hit ~$5.2B as inference costs on Google/AWS infrastructure exceeded projections.

Anthropic rolls out Claude Opus 4.5, a mid-generation bump focused on complex long-context reasoning and reduced hallucination rates.

Anthropic's October data point shows an annualized revenue run rate closing in on $7 billion, driven by large enterprise deals and the expanding Claude API ecosystem.

First-class capability packs that the model can invoke autonomously, structured to compose into longer agentic workflows.
