Anthropic

Anthropic is the AI safety company behind the Claude family of models. Founded in 2021 by former OpenAI researchers Dario and Daniela Amodei, Anthropic has built a reputation for producing models that lead on reasoning and code generation benchmarks while emphasizing safety research. Their newest model, Claude Fable 5, launched June 9, 2026 as a frontier tier above Opus: $10 input / $50 output per million tokens, a 1 million token context window with 128K output, always-on adaptive thinking, and vendor-reported scores of 80.3 on SWE-bench Pro and 85.0 on OSWorld-Verified. Claude Opus 4.8, which shipped on May 28, 2026 just six weeks after Opus 4.7, remains the default model. Opus 4.8 keeps the 1 million token context window and the $15 input / $75 output pricing while improving agentic coding (64.3% to 69.2% on Anthropic's own measure), honesty about its own progress, and long-horizon autonomy, with a fast mode that is roughly 2.5x quicker and three times cheaper than before. In late April 2026 the company secured up to $25 billion in additional Amazon investment (April 21) and up to $40 billion in compute and capital from Google (April 24). On May 28, 2026 Anthropic closed a $65 billion Series H at a $965 billion post-money valuation, and on June 1 it confidentially filed a draft S-1 with the SEC for a proposed IPO, getting ahead of rival OpenAI. Their Model Context Protocol (MCP) has become foundational infrastructure for AI agents.
