Meta大幅压低AI编程模型成本——条件是使用客户代码进行训练
meta发布了muse spark 1.2和编程代理，如果用户授予数据权限，输出代币价格低至每百万0.20美元，加剧了同质化竞争。
meta released muse spark 1.2, an upgrade focused on code generation and long-horizon planning, alongside its first dedicated coding agent, muse code. the agent uses persistent sub-agents and a crash-recovery protocol to resume work exactly where it left off. pricing starts at $1.25 per million input tokens, but a new 'data-sharing' tier offers output tokens for just $0.20, significantly undercutting western competitors like anthropic and openai. internal benchmarks position spark 1.2 between its predecessor and top models like claude opus 5, though comparisons are complicated by proprietary agent environments.
