Google’s AI Leadership Shakeup: Disaster or Exactly What It Needs?

Today on the AI Daily Brief, a massive AI leadership shake up at Google. And before that on the headlines, Meta drops two new models and a coding harness.

Alongside the twin model release, they are releasing their first coding harness as well. Meta described Muse Spark 1.2 as a coding focused update to the 1.1 version which was released in July. This is the first model that Meta has trained in a harness, improving its agentic capabilities in that environment. The results look like a pretty strong coding model on the benchmarks. It scored 82.9% on terminal bench 2.1, placing it between Opus five and GPT five six Terra. On DeepSuite, it scored 59.3%, placing it behind Opus five and GPT five six Terra, trailing by around five points. Meta chose not to compare Muse Spark to the Frontier models likely because it's not in the same size class as Fable five or GPT five six Sol, and the model appears to be designed to be cheap and efficient as a daily driver rather than taking on the larger models on the benchmarks. Artificial analysis had similar findings. The model scored 54 on the a a intelligence index, placing it behind Opus five, GPT five six, Terra, and KIMI k three, tying it with Croc 4.5 and putting it a few points ahead of GLM 5.2. AA also wrote that Spark 1.2 is, quote, among the most cost efficient models at its intelligence level. It cost 40¢ per task on their benchmark run, which gave it a similar cost to intelligence ratio as GROC 4.5 and GPT 5.6 Sol turned down to medium effort settings. Its run was around half the cost of Kimi k three, further reinforcing the idea that every Chinese model is not just some incredibly low cost wonder. NewSpark one point two's run on the AA index was around half the cost of Kimi k three with results in the same ballpark. AA also noted that the three point overall improvement was almost entirely down to agentic performance. The update delivered a big jump on GDP Val, making it the sixth highest ranked model behind Opus five, Fable five, Quen 3.8 Max, GPT 5.6 Soul, and Kimi k three. On the harness side, the biggest thing besides Meta actually bringing a coding harness to market is sub agents.
