ANTHROPIC

Anthropic Launches Claude Fable 5.2 and Mythos 5.2

Anthropic has introduced two new AI models, Claude Fable 5.2 and Claude Mythos 5.2, with improvements in coding, reasoning and vision.

Details:

• Fable 5.2 and Mythos 5.2 are Anthropic’s most advanced offerings, generating outputs 30% faster than Claude Fable 5.1 and Claude Mythos 5.1 while costing 20% less, at $8 per million input tokens and $40 per million output tokens.

• Fable 5.2 debuted at No. 1 on the Artificial Analysis Intelligence Index leaderboard with a score of 65, five points ahead of Gemini 4 Carbon and six points ahead of Claude Opus 5.5.

• Dianne Penn, Anthropic’s head of product management for research, said Fable 5.2 is intended for “power users or power use cases” (such as hard problems in engineering, mathematics and robotics) because it excels at complex, open-ended technical work, while models like Claude Opus 5.5 are better suited for daily tasks.

• Fable and Mythos are the same underlying model, but Fable has strong cybersecurity and biology safeguards to guard against misuse. Mythos 5.2 will initially be available only to vetted organizations.

• Fable 5.2 has been available to select partners in pre-release for a while, and Anthropic says the model has already “solved two open problems in theoretical physics, formalized Fermat’s Last Theorem, and supported numerous other research projects.”

The launch marks the first time that Anthropic has released so-called “frontier” models since its CEO, Dario Amodei, called to slow down the pace of AI development in September. Anthropic said the models underwent rigorous safety and alignment testing, and that it built new evaluations and post-launch monitoring tools before the release.

It's time to set up your holiday streaming campaign

Are you ready to reach holiday shoppers on CTV? For many streamers, the season is already underway.

Last year, according to Roku internal data, holiday content searches on Roku saw an 86% increase during October. And in November, those searches rise an average of 39% weekly. This surging holiday spirit is mirrored by consumer activity, as about half of Roku streamers shopped Black Friday and Cyber Monday deals in 2025.

Meeting those shoppers is easier than you might think. Begin with the seasonal outcome you hope to drive: awareness, online sales, leads, store visits, or another measurable goal. From there, define your audience, upload your creative, set the budget and campaign dates, and establish measurement before launching. You can even create a shoppable ad unit that lets streamers buy with a click of their remote.

Our holiday playbook offers a month-by-month guide to reaching shoppers during this all-important time of year.

First-time spenders get a $5,000 match on the first $5,000 spent with code BEEHIIV5K. Terms apply.

Launch your campaign today.

META

Meta Introduces Muse Ember, Its Most Cost-Efficient AI Model

Meta has released Muse Ember, a lightweight AI model built to handle repetitive tasks in AI agent workflows at scale. The company is positioning it as a low-cost option for coding subtasks, tool calls, data extraction, and document processing, designed to work alongside more powerful models.

Details:

• Meta describes Ember as its lightest and most cost-efficient Muse model so far, with a focus on complex reasoning execution and tasks agents perform repeatedly.

• The model costs $0.10 per million input tokens, putting it below larger competitors such as Anthropic's Haiku and OpenAI's Luna. Meta also says its cost and benchmark performance make it competitive with open-weight models like DeepSeek V4.1 Flash and GLM 5.3 Flash.

• Ember is designed to work alongside a larger model such as Muse Wonder. The larger model can plan and establish instructions, while Ember handles high-volume execution across thousands of tasks.

• Meta has trained Ember to process multiple types of media, including text, images, and audio. Agents can use it to interpret screenshots, charts, scanned documents, voice recordings, and video without switching between separate models.

The model is the fourth release under Meta's Muse brand, following Muse Spark, its open-source counterpart Glimmer, and the flagship Muse Wonder.
