Muse Spark 1.3

meta/muse-spark-1.3 is Meta's Muse Spark 1.3, the successor to Muse Spark 1.2: a multimodal reasoning model for complex agentic tasks. Text, images, video, audio, and PDF in; text out. 1,048,576-token context. Reasoning, function calling, and vision. Routed over AIHubMix BYOK (wire muse-spark-1.3); list $1.375 / $4.675 per 1M tokens. Not a free SKU — no platform aihubmix hop.

Try it in the Vercel AI SDK. createAnyRouter() reads ANYROUTER_API_KEY:

import { createAnyRouter } from "@anyr/ai-sdk-provider"
import { generateText } from "ai"

const anyrouter = createAnyRouter()

const { text } = await generateText({
  model: anyrouter("meta/muse-spark-1.3"),
  prompt: "Summarize this diff in three bullets.",
})
console.log(text)

Or launch a coding agent through the anyr CLI:

anyr claude --model "meta/muse-spark-1.3"
