Muse Ember, Claude Fable 5.2 and Drex Max

Meta's smallest Muse model joins the catalog (and is what stealth/crouton-alpha turned out to be), Anthropic's Claude Fable 5.2 lands at $8 / $40 per 1M tokens, and Nace AI's Drex Max v1.1 and Drex Max Finance cover multimodal decisions.

Muse Embermeta/muse-ember · Meta's smallest Muse, built for scalable agentic execution: tool calls, coding subtasks, routing and long documents, 1M context, text/image/audio/video in, text out. $0.10 / $0.50 per 1M list. This is the reveal of the stealth/crouton-alpha preview.
Claude Fable 5.2anthropic/claude-fable-5-2 · Frontier model for demanding technical work, 20% below Fable 5.1 at $8 / $40 per 1M, cache reads $0.20, 1M context, 128K max output, always-on adaptive thinking (default high effort). Alternatives: anthropic-byok, Bedrock, Vertex and Foundry BYOK, OpenRouter BYOK.
Drex Max v1.1nace-ai/drex-max-v1.1 · Nace AI's largest multimodal decision model and successor to Drex Max: application state (text or JSON) plus up to 8 images in, calibrated probabilities for noul / choice / score questions out, System One shape. Call POST /api/v1/decisions.
Drex Max Financenace-ai/drex-max-finance · Nace AI's multimodal decision model for finance: same System One shape as Drex Max, tuned for invoice handling, fraud, credit and filing checks, images in, calibrated probabilities out. Call POST /api/v1/decisions.

Meta released meta/muse-ember, the smallest model in the Muse family, designed for scalable agentic execution: tool calls, coding subtasks, routing and processing large collections of images, files, audio and video, with a 1M-token context. Stealth watchers will recognize it: stealth/crouton-alpha was an early version of Muse Ember, and that listing is stopped — requests are routed to Muse Ember from now on.

Anthropic shipped anthropic/claude-fable-5-2 on 2026-11-09: $8 / $40 per 1M tokens (20% below Fable 5.1), cache reads at $0.20, 1M-token context, 128K max output and adaptive thinking on by default at high effort. Available BYOK through Anthropic, Amazon Bedrock, Google Vertex AI, Microsoft Foundry and OpenRouter.

nace-ai/drex-max-v1.1 is the successor to Drex Max for image-capable decision work and nace-ai/drex-max-finance is tuned for finance — invoice, fraud, credit and filing checks. Both return calibrated probabilities, not text: POST /api/v1/decisions with typed questions (noul / choice / score) and read the probabilities straight into your workflow.
