Meta大幅壓低AI編程模型成本——條件是使用客戶代碼進行訓練
meta發布了muse spark 1.2和編程代理，如果用戶授予數據權限，輸出代幣價格低至每百萬0.20美元，加劇了同質化競爭。
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.
