On September 2, 2026, Meta released Muse Spark 1.3, its fourth model in five months, tuned for agentic and coding work: 20% fewer tool calls, 25% fewer tokens, and better calibration on irreversible actions. It is a change of direction — an agent’s value is now measured by its cost, not just its benchmark score.

On August 12, 2026, SpaceXAI shipped Grok 4.6, which scores 61 on the Artificial Analysis Intelligence Index — level with GPT-5.6 Sol — at $2/$6 per million tokens, and finishes long-horizon agentic tasks in half the turns of Claude Opus 5. For anyone building agents, the deciding variable is no longer the benchmark, it is the cost and token count burned per task.
