What happened
Meta's Muse Spark 1.3 launched claiming frontier-level performance matching GPT-5.6-Sol, ranked #3 globally per AAII, with open weights promised soon and a pricing model offering 90%+ discounts if users opt in to training on their data. Separately, Stanford replaced 85% of its Fall 2025 software engineering curriculum with agent-focused topics including context engineering, MCP portals, and parallel background agents, alongside a new CS329Z course on building agents from scratch.
Why it matters
If you're selecting a frontier model for coding or agentic work, Muse Spark 1.3's opt-in-training pricing could cut your API costs by over 90% — evaluate whether your data sensitivity allows it before defaulting to OpenAI or Anthropic. The open weights promise means you should also plan for a self-hosted fallback path once weights drop. The Stanford curriculum reset signals that agent engineering skills (harnesses, evaluation, orchestration) are becoming the baseline expectation for new hires, not a niche.
Discussion angle
Would you opt in to training for a 90% API discount, and what data boundaries would you set — does the cost saving justify the risk for your specific workload?
