Grok 4.7 is out. Coding first, chat later

Brian · AI News — Mon, 21 Sep 2026 23:38:17 +0000

Grok 4.7 shipped today after the long cook delay. Same price and speed as 4.6 on the standard API. Bigger base model and more training on long jobs that take hours. Live in Cursor Grok Build and the API. GitHub Copilot is rolling it out too.

The catch people should read carefully. Standard rates match 4.6 but the model can burn a lot more output tokens when thinking is cranked up. Twice as fast at half the price is a rival comparison headline, not a cut to your old Grok bill. Consumer Grok inside X comes later per the model card. Coding and work tools are the start.

Gemini 4 Pro Arena chatter. Still unconfirmed.

Brian · AI News — Mon, 21 Sep 2026 17:09:46 +0000

Another Arena ghost showed up this week. People think it is Gemini 4 Pro hiding under a Flash style label. Codename chatter says Argon. Screenshot dumps claim wins over Astra and Fable on coding and agent tasks. Huge context and cheaper API numbers are floating too.

Google has not confirmed any of it. No model card. No launch date. Treat the scoreboard posts as rumor until something official lands.

Worth watching because a cheaper long context Pro would actually move how people build agents. Not because the leaderboard screenshots look dramatic.

Cluster rumor week. Sol Opus and Grok chatter

Brian · AI News — Mon, 21 Sep 2026 15:43:04 +0000

The rumor board is crowded this week. GPT 6 Sol is still unconfirmed even as Altman talk about a delayed major drop keeps looping. Claude Opus 5.5 is still mostly one leaker story with a Tuesday whisper. Grok 4.7 keeps sliding after Musk said it needed more cook time.

None of that is a ship notice. Watch for a model card API id or a first party blog. Until then treat the stack as chatter plus the Reuters line that Anthropic is weighing a new model ahead of IPO talks.

Claude Opus 5.5 leak chatter — Tuesday rumor, thin receipts

Brian · AI News — Mon, 21 Sep 2026 07:07:12 +0000

Community posts are floating a Claude Opus 5.5 story again: internal string claude-wafer-eap, rumored ~$4/$20 API pricing, and a possible Tuesday (Sep 22) window. Anthropic has not announced any of that.

What is documented recently is messier and more useful: an unreleased Opus build was reportedly served under the normal Opus label, then briefly cut (the “midnight shock” chatter). Treat the 5.5 name + price sheet as rumor until there’s a model card or API id.

AI model rumor roundup — what I’m watching this week

Brian · AI News — Mon, 21 Sep 2026 06:30:14 +0000

This week the rumor mill is louder than the release notes. I’m watching a few claims that keep circulating: a Kimi / Claude Opus / DeepSeek leak cluster, a Gemini 3.8 Live plus Siri plus MiniMax roundup, and a game-generation demo people are calling a Fortnite-style Fable clone. Most of these are still a screenshot plus a statement, so I’m treating them as leads, not facts.

What I actually want before I repeat a rumor is the source, the date, and one place the claim fails. ByteForward’s leak walkthrough is the clip I keep replaying for the Kimi / Opus / DeepSeek thread: https://www.youtube.com/watch?v=KlIIpPrQ4X8

The other one I’m pairing with it is their Gemini 3.8 Live / Siri / MiniMax roundup, which at least puts the competing claims next to each other instead of in a single viral screenshot: https://www.youtube.com/watch?v=B64RW5Ptc-Q

If a demo only looks good in the trailer and never survives a “don’t summarize” or “show the physics” check, I’m not calling it shipped. That’s the bar for this week.
