Meta Launches Muse Spark 1.3 to Rival GPT-5.6 Sol
Meta has released Muse Spark 1.3, the latest iteration of its AI model family, designed for longer agentic workflows, complex coding tasks, and reliable processing of extensive instructions. The model improves collaboration by maintaining context in long chats, distinguishing multiple tasks, and asking for clarification. It also enhances safety against prompt injection and irreversible actions. Reportedly, Muse Spark 1.3 uses about 20% fewer tool calls and 25% fewer tokens than its predecessor, with a more compact coding style. In Meta's benchmarks, it outperforms rivals GPT-5.6 Sol and Opus 5 on the long-context MRCR test (98.5 vs 91.5 points) and several coding benchmarks, though it trails in others like DeepSearchQA. The model is available in Muse Code and via the Meta Model API, with a Max-Reasoning mode and an Open-Weights version announced.
Technical Release from Meta, a Major Platform, advancing agentic AI model capabilities used in MarTech and AdTech automation, reinforcing competitive pressure on rival foundation models.

Meta unveils Muse Spark 1.1 agent model
Meta released Muse Spark 1.1, an agent-focused multimodal model designed to plan tasks, coordinate parallel AI sub‑agents, use external tools and execute end‑to‑end workflows. Muse Spark 1.1 supports images, video and audio, claims a context window up to one million tokens, and emphasizes visual‑to‑code generation and agentic control of desktop/web interfaces. Meta published internal benchmarks placing Muse Spark 1.1 competitive with current frontier models (GPT‑5.5, Claude Opus 4.8, Google Gemini 3.1 Pro) for agents and coding tasks. Meta also published API pricing (USD 1.25 per 1M input tokens; USD 4.25 per 1M output tokens) and offers $20 trial credit for new accounts. Demos shown include automating a Facebook Marketplace listing and debugging/code migration workflows, and Meta says developers and researchers already use the model for daily development and research tasks.
Meta's Muse Spark 1.3 Nears Top AI Rankings
Meta released Muse Spark 1.3, its latest frontier AI model, scoring 61 on the Artificial Analysis Intelligence Index and 62 on max preview, tying or surpassing GPT-5.6 Sol, Grok 4.6, and Claude Opus 5, with only Anthropic's Claude Fable 5.1 and Claude Opus 5 ranking higher. Gains stem from improved agentic tasks and scientific reasoning. Pricing is aggressive at $0.55 per Intelligence Index task, while token costs remain unchanged from version 1.2. The model is available in Muse Code and via API. Meta committed to open-weight releases of Muse Spark 1.2, but 1.3 remains undecided, potentially impacting the open-source ecosystem. Additionally, OpenAI's GPT-6 Astra scores 61 but carries significantly higher API costs.
Meta launches Muse Spark 1.1 for agentic coding
Meta publicly launched Muse Spark 1.1, a multimodal AI model aimed at agentic coding and enterprise automation. Spark 1.1 can perform multi-step reasoning, manage digital workflows, fix bugs and assist with large code migrations, according to Meta. Reuters reported Meta will price the model at $1.25 per million input tokens and $4.25 per million output tokens, putting it roughly in line with offerings from Anthropic and OpenAI. CEO Mark Zuckerberg posted about the release on X, calling Spark strong on agentic performance and computer/tool use and indicating more model releases are forthcoming. The launch positions Meta as a late but competitive entrant in an intensifying market of coding-capable foundational models.
