It is a coding-focused update to the previous Muse Spark model. While keeping its general capabilities, 1.2 ships with improvements in code generation, complex debugging, codebase understanding, and end-to-end developer workflows.\n\nThe model is built for long-horizon work like generating whole repositories, building out large projects end to end, and sustaining iterative loops where it writes, compiles, profiles, and improves code over many rounds.\n\nTo use Muse Spark 1.2, set `model`\n\nto `meta/muse-spark-1.2`\n\nin the [AI SDK](https://ai-sdk.dev/):\n\nTo use Muse Spark in a [coding agent](https://vercel.com/docs/ai-gateway/coding-agents), run `vercel ai-gateway coding-agents setup`\n\nto connect Claude Code, Codex, OpenCode, or Pi, then select `meta/muse-spark-1.2`\n\ninside the agent.\n\nAI Gateway provides a unified API for calling models, tracking usage and cost, and configuring retries, failover, and performance optimizations for higher-than-provider uptime. It includes built-in [custom reporting](https://vercel.com/changelog/custom-reporting-ai-gateway), [Zero Data Retention support](https://vercel.com/blog/zdr-on-ai-gateway), [budgets for API keys](https://vercel.com/docs/ai-gateway/authentication-and-byok/api-keys), [routing rules](https://vercel.com/docs/ai-gateway/models-and-providers/routing-rules), and more.\n\nAI Gateway reflects provider pricing with no markup and does not charge a platform fee on inference, including on [Bring Your Own Key](https://vercel.com/docs/ai-gateway/authentication-and-byok/byok) (BYOK) requests.\n\nTry Muse Spark 1.2 in the [model playground](https://vercel.com/ai-gateway/models/muse-spark-1.2).", "url": "https://wpnews.pro/news/muse-spark-1-2-is-now-available-on-vercel-ai-gateway", "canonical_source": "https://vercel.com/changelog/muse-spark-1-2-is-now-available-on-vercel-ai-gateway", "published_at": "2026-08-05 00:00:00+00:00", "updated_at": "2026-08-09 13:02:40.698478+00:00", "lang": "en", "topics": ["artificial-intelligence", "large-language-models", "ai-products", "developer-tools"], "entities": ["Meta", "Muse Spark 1.2", "Vercel AI Gateway", "AI SDK", "Claude Code", "Codex", "OpenCode", "Pi"], "alternates": {"html": "https://wpnews.pro/news/muse-spark-1-2-is-now-available-on-vercel-ai-gateway", "markdown": "https://wpnews.pro/news/muse-spark-1-2-is-now-available-on-vercel-ai-gateway.md", "text": "https://wpnews.pro/news/muse-spark-1-2-is-now-available-on-vercel-ai-gateway.txt", "jsonld": "https://wpnews.pro/news/muse-spark-1-2-is-now-available-on-vercel-ai-gateway.jsonld"}}
