Anthropic builds its Claude models in size tiers. Haiku is the smallest and cheapest tier for many fast requests such as classification, routing, or subagents. Sonnet is the faster, lower-cost alternative to Opus for bug fixes, documents, slides, and spreadsheets. Opus is the large model for long, difficult work such as coding sessions that run for hours.
Since June 2026 there are two tiers above Opus. Fable is generally available through the API. Mythos shares its model core with Fable but stays reserved for vetted partners in the Glasswing program. The version number shows the generation, so Claude Opus 5.5 is newer than Claude Opus 5. A new generation does not always arrive for every tier at once.
Language model · Oct 7, 2026
What is new in Claude Haiku 5.5 is that Anthropic offers adjustable effort on a Haiku model for the first time. It follows Claude Haiku 4.5 and grows the context window from 200,000 to 1 million tokens. Anthropic positions it for classification, routing, extraction, and subagents, wherever many requests need fast answers.
Language model · Sep 28, 2026
What is new in Claude Sonnet 5.5 is its gap in Anthropic’s Terminal-Bench 4.0 comparison. Sonnet 5.5 scored 70.6%, while Claude Sonnet 5 scored 10.3%. It launched alongside Claude Opus 5.5 as the faster, lower-cost option.
Language model · Sep 22, 2026
What is new in Claude Opus 5.5 is the endurance Anthropic describes for long coding sessions. An early tester used it to migrate 680,000 lines of code in less than a day. Anthropic places the model near Claude Fable 5.1 on many tasks and lists the Opus variant alongside Claude Opus 5.
Language model · Sep 1, 2026
What is new in Claude Fable 5.1 is that Anthropic makes the shared Fable and Mythos model core broadly available. According to Anthropic, Claude Mythos 5.1 uses the same core but remains safeguarded for vetted programs. Fable 5.1 follows Claude Fable 5.
Language model · Jul 24, 2026
At launch, Claude Opus 5 was the default model for Claude Max and the strongest model in Claude Pro. It followed Claude Opus 4.8 and, according to Anthropic, brought much of Claude Fable 5’s capability into a generally available Opus model.
Language model · Jun 30, 2026
New in Claude Sonnet 5 was a tokenizer that Anthropic says can turn the same text into up to 35% more tokens, depending on its content. It followed Claude Sonnet 4.6 and has since been superseded by Claude Sonnet 5.5. In Anthropic’s BrowseComp and OSWorld-Verified comparisons, high-effort performance can match Claude Opus 4.8 on some tasks.
Language model · Jun 9, 2026
Claude Fable 5 was the generally available half of the model core it shared with Claude Mythos 5 from June 9, 2026. It was the direct predecessor to Claude Fable 5.1, combining demanding software work, knowledge work, and vision with safety classifiers.
Language model · April 2026
What was new in Claude Opus 4.7 was, according to Anthropic, the combination of demanding software work and higher-resolution image understanding. It followed Claude Opus 4.6 and preceded Claude Opus 4.8.
Language model · February 2026
Claude Opus 4.6 was the first Opus model with a one-million-token context window. It followed Claude Opus 4.5 and preceded Claude Opus 4.7. Anthropic also launched it alongside API context compaction and agent teams in Claude Code.
Language model · February 2026
What was new in Claude Sonnet 4.6 was its one-million-token context window, which Anthropic initially offered in beta. It followed Claude Sonnet 4.5, preceded Claude Sonnet 5, and became the default model for Free and Pro at launch.
Language model · November 2025
Claude Opus 4.5 was distinguished, in Anthropic’s description, by handling trade-offs in multi-step tasks. It launched in November 2025, was the direct predecessor to Claude Opus 4.6, and combined coding with research, slides, and spreadsheets.
Language model · October 2025
What was new in Claude Haiku 4.5 was Anthropic’s reported coding performance near the Sonnet 4 of that period, at one-third the cost and more than twice the speed. Anthropic released it in October 2025 as the successor to Haiku 3.5.
