The model improves on prior versions for agent work and coding, requiring fewer turns and producing less filler. Pricing remains unchanged from Muse Spark 1.2 at $1.25 per million input tokens, $4.25 per million output tokens, and $0.15 per million cached input tokens on the standard tier, with contributor tier rates of $0.10, $0.20, and $0.002 respectively.", "body_md": "[Muse Spark 1.3 from Meta](https://vercel.com/ai-gateway/models/muse-spark-1.3) is now available on AI Gateway, in both the standard and contributor pricing tiers.\n\nThis model improves on prior Muse Spark models at agent work and coding, with a 1M token context window and text, image, and PDF input. On coding it takes fewer turns and writes less filler than the previous release.\n\nTo use Muse Spark 1.3, set `model`\n\nto `meta/muse-spark-1.3`\n\n:\n\n[Muse Spark 1.3 Contributor](https://vercel.com/ai-gateway/models/muse-spark-1.3-contributor) is a pricing tier on the same model rather than a separate one, with the same weights, capabilities, and context window. The difference is that Meta uses the inputs and outputs sent to this tier to train and improve its models, and pricing is lower in exchange.\n\nModel | Input | Output | Cached input |\n| $1.25 | $4.25 | $0.15 |\n| $0.10 | $0.20 | $0.002 |\n\nRates are per million tokens and unchanged from Muse Spark 1.2 on both tiers.\n\nTo use it in a coding agent, see the [coding agents guide](https://vercel.com/docs/ai-gateway/coding-agents), then run `vercel ai-gateway coding-agents setup`\n\nto connect Claude Code, Codex, Cursor, and more, then select `meta/muse-spark-1.3`\n\nin the agent.\n\nTry Muse Spark 1.3 in the [model playground](https://vercel.com/ai-gateway/models/muse-spark-1.3).\n\nYou can view [all language models](https://vercel.com/ai-gateway/models?type=text) available on AI Gateway.", "url": "https://wpnews.pro/news/muse-spark-1-3-now-available-on-ai-gateway", "canonical_source": "https://vercel.com/changelog/muse-spark-1-3-now-available-on-ai-gateway", "published_at": "2026-09-02 00:00:00+00:00", "updated_at": "2026-09-02 21:52:00.496126+00:00", "lang": "en", "topics": ["large-language-models", "ai-products", "ai-tools"], "entities": ["Meta", "Vercel", "AI Gateway", "Muse Spark 1.3"], "alternates": {"html": "https://wpnews.pro/news/muse-spark-1-3-now-available-on-ai-gateway", "markdown": "https://wpnews.pro/news/muse-spark-1-3-now-available-on-ai-gateway.md", "text": "https://wpnews.pro/news/muse-spark-1-3-now-available-on-ai-gateway.txt", "jsonld": "https://wpnews.pro/news/muse-spark-1-3-now-available-on-ai-gateway.jsonld"}}
