Meta launches Muse Spark 1.1 API at 25% of OpenAI/Anthropic pricing; $1.25/$4.25 per M tokens
Meta released its first paid API for a proprietary AI model, Muse Spark 1.1, priced at $1.25 per million input tokens and $4.25 per million output tokens—roughly one-quarter the cost of OpenAI's GPT-5.5 ($5/$30) and Anthropic's Claude Opus 4.8 ($25+/$25-50). Meta Superintelligence Labs is positioning the multimodal model as an agentic-systems powerhouse, built for tool use, computer vision, and code generation, with support for the OpenAI and Anthropic SDK patterns to lower developer switching friction.
The pricing move marks Meta's strategic shift from open-weights Llama to a closed, paid API strategy—a major departure. CEO Mark Zuckerberg called the strategy "very aggressive and attractive," emphasizing Meta's scale advantage: the company has spent hundreds of billions on data-center capex and custom AI chips, allowing it to sustain lower margins that pure-play labs like OpenAI and Anthropic cannot. The model leads Meta's internal benchmarks on MCP Atlas (88.1) and Humanity's Last Exam (62.1), trailing Claude Opus 4.8 on SWE-Bench Pro but performing competitively on agent and coding tasks.
The Meta Model API launch lands just hours after xAI opened Grok 4.5 at $2/$15 (slightly cheaper for output tokens), briefly claiming the cost crown. This consolidates a visible price war: in the past 48 hours, OpenAI, Meta, and xAI have all announced or deployed aggressive pricing. For enterprises and agent-builders shopping for inference cost, the structural calculus has shifted—margin pressure for OpenAI and Anthropic is now public, and builders expect downward pricing pressure to continue through 2026.
