Claude Fable 5.2 and Mythos 5.2 are here to raise the bar for AI coding and scientific research
Anthropic has introduced two of its most powerful AI models yet, Claude Fable 5.2 and Mythos 5.2, just over two months after launching their 5.1 versions.

The short version Anthropic shipped Claude Fable 5.2 and Claude Mythos 5.2 on November 9. On the surface it is a routine upgrade: faster, cheaper, higher benchmark scores. The interesting part is the structure — one underlying model, two different doors into it — and the fact that Anthropic is now pricing by the task, not just by the token. Three numbers to hold on to: Price: $8/$40 per million tokens, down 20% from 5.1's $10/$50 Speed: output up to 30% faster than 5.1, plus a fast mode at up to 2.5x speed for double the price ($16/$80) Benchmarks: 49.1% on FrontierCode 2.0, ahead of Opus 5.5…

Anthropic PBC today pulled back the curtains on Claude Fable 5.2 and Claude Mythos 5.2, its two most capable large language models to date. The LLMs are identical as far as their core capabilities are concerned. The difference is that Fable 5.2 blocks certain biology and cybersecurity use cases, while Mythos 5.2 includes more relaxed […] The post Anthropic launches Fable 5.2 and Mythos 5.2 with science, coding upgrades appeared first on SiliconANGLE .

Anthropic announced today, November 9, 2026, two new models: Claude Fable 5.2 and Claude Mythos 5.2. They succeed Fable 5.1 and Mythos 5.1 from September, and Anthropic is positioning them for what it calls "the most ambitious, open-ended technical work" — agentic coding, cybersecurity, scientific research, and long-horizon reasoning. The headline numbers: outputs up to 30 percent faster than the 5.1 versions, fewer tokens used on hard tasks, and lower prices — $8 per million input tokens and $40 per million output tokens. I have not run these models yet — nobody outside Anthropic had access…

We have not tested this hands-on, and nothing here is a hands-on finding. Anthropic announced today, November 9, 2026, two new models: Claude Fable 5.2 and Claude Mythos 5.2. They succeed Fable 5.1 and Mythos 5.1 from earlier this year — and Anthropic says they are more capable, noticeably faster, and, for most customers, cheaper to run.

Anthropic today introduced its latest models, Claude Fable 5.2 and Claude Mythos 5.2, which have improvements in coding, reasoning, and vision. Anthropic says Fable 5.2 and Mythos 5.2 communicate more clearly than the 5.1 versions, with outputs generated up to 30 percent faster. Fable 5.2 uses fewer tokens than Fable 5.1 on challenging tasks when set to medium effort. The company suggests using Fable and Mythos for "the most ambitious, open-ended technical work." Anthropic recommends starting with Opus 5.5 for most coding and knowledge tasks, then switching to a model like Fable or Mythos that can handle more complex requests, or stepping down to a more affordable model like Sonnet or Haiku 5.5. Benchmarks suggest Fable and Mythos 5.2 outperform Opus 5.5 for computer use, knowledge work, cybersecurity, agentic scientific research, agentic coding, multidisciplinary reasoning, and more. Both use the same underlying model, but the public-facing Fable 5.2 model has cybersecurity and biology safeguards to prevent misuse. Compared to Fable 5.1, Fable 5.2 has approximately 55 percent fewer blocks. Mythos does not have the same limitations as Fable, and it is available through Anthropic's Life Sciences and Cyber Verification Programs as well as through Claude Security on Enterprise plans. Fable 5.2 is available today on all platforms. Subscribers on eligible paid plans have extra Fable usage this week, with one to three Fable resets based on subscription length. Fable is included for up to 50 percent of weekly usage limits for Pro plans and standard seats on the Team plan. A fast mode that speeds up token generation by up to 2.5 times is available on Claude Code, the Claude Platform, Claude Models on Google Cloud, and Microsoft Foundry.
