Anthropic Files for IPO, Gaining Edge Over OpenAI
Anthropic PBC filed for a confidential IPO, gaining a first-mover advantage over OpenAI in the competitive AI startup landscape. The move positions Anthropic to secure fundraising benefits that could influence the broader battle for computing power. Both companies are vying for dominance in the AI space. The race to go public is not just about prestige, but about securing access to critical resources such as chips, data centers, and talent needed to develop advanced AI models.

Claude Fable 5 is the flagship model in Anthropic’s Claude family, released on 9 June 2026 as the first publicly available Mythos‑class system, positioned above the earlier Opus line. It runs on Mythos 5 weights with active safety classifiers and supports a one‑million‑token context window, while enforcing a mandatory 30‑day data retention policy and returning refusals with a stop_reason of “refusal.”
Claude Mythos is the flagship version of Anthropic’s Claude family, launched on 9 June 2026 and currently active. It incorporates a knowledge base up to January 2026 and supports an unusually large context window of one million tokens, enabling it to process substantially longer inputs than prior releases.
Claude Opus 4.8 is the current flagship model in Anthropic’s Claude family, released on 28 May 2026 and listed as active. It retains a 1‑million‑token context window and is positioned as a reliability‑focused iteration, reported to be about four times less likely than its predecessor (Opus 4.7) to allow code flaws to pass unnoticed, with tiered pricing options for different effort levels.

Claude Opus 4.7 is the flagship model in Anthropic’s Claude series, released on 16 April 2026 and currently active. It expands the context window to one million tokens and triples image resolution to 3.75 MP while adding “xhigh” effort mode and self‑verification capabilities, achieving an 87.6 % verification rate on SWE‑bench; it has since been superseded by Claude Opus 4.8 but remains available.
Claude Sonnet 4.6 is a balanced‑tier iteration of Anthropic’s Claude family that entered default service on 17 February 2026. It features an expanded context window of up to one million tokens, allowing it to process substantially longer inputs than earlier releases in the series.
Claude Opus 4.6 is the flagship version of Anthropic’s Claude series released on 5 February 2026 and now superseded by Opus 4.8. It made the one‑million‑token context window generally available without an additional surcharge, introduced a longer 14.5‑hour task window and native Agent Teams functionality, and achieved a reported 78.3 % MRCR v2 at the full context length.
Claude Opus 4.5 is the flagship version of Anthropic’s Claude series released in November 2025 and remains active. It offers a 200 000‑token context window (with a 1 million‑token beta option) and introduced an efficiency‑focused pricing change, resetting the cost to $5/$25 while reducing output tokens by roughly three‑quarters, positioning it as the most affordable Opus model with the large‑context capability.
Claude Haiku 4.5 is an active, fast‑tier iteration of Anthropic’s Claude family released on 1 October 2025. It retains a knowledge cutoff of February 2025 and expands the context window to roughly 200 000 tokens, offering broader prompt capacity compared with earlier releases in the series.
