AI Pricing Plummets: Grok 4.5, GPT-5.6, and Muse Spark 1.1 Ignite Fierce Price War

A new wave of AI models from SpaceXAI, OpenAI, and Meta, including Grok 4.5, GPT-5.6, and Muse Spark 1.1, has dramatically slashed pricing in early July 2026, intensifying competition for enterprise adoption and signaling a major shift in the AI market's economics.

The top 3

  1. Lowest Token Cost: Muse Spark 1.1 offers the lowest hosted input cost at $0.60 per million tokens and $2.40 per million output tokens, with potential for even lower self-hosted costs.
  2. Agentic Task Leader: Grok 4.5 excels in cost-efficiency for agentic coding tasks, priced at approximately $0.165 per run, making it 35-40% cheaper than GPT-5.6 Sol for such workloads.
  3. GPT-5.6 Sol: Premium: GPT-5.6 Sol, despite its higher price point of $5 input / $30 output per million tokens, offers strong capabilities and extended reasoning modes, positioning it as a premium option for complex tasks.
