I take it all back. We just got access to eval Grok 4.5 and it has landed above GPT-5.6-Sol and just shy of Opus for browser use. Because cache input is expensive, the overall cost is only 10% cheaper than opus. Its overall a bit faster. We have another opus-class model in the competition


We've reset 5-hour and weekly rate limits for all users.



GPT-5.6 Sol, along with Terra and Luna, will launch publicly this Thursday. We’re expanding preview access globally now.

Didn’t know Zuck had a Twitter account. His last tweet was in 2023. Pretty much confirms X is the best place to talk about AI.

We’re excited to introduce Muse Spark 1.1, a significant upgrade from the first Muse Spark model we released earlier this year. Along with this release, we are launching a public preview of the new Meta Model API where developers can access Muse Spark 1.1. The model is also available now in "Thinking" mode in the Meta AI app and on meta.ai. Learn more: go.meta.me/ff8e2c


I didn't expect to say this... But after one day with Grok 4.5 from @SpaceXAI, I've already started moving some of my Claude Code and Codex workflows over. It's ridiculously fast, and the intelligence is way better than I expected. Huge props to @elonmusk and the team. If you're paying $8/month for X Premium, you've already got plenty of Grok usage included. It's worth trying.
