Grok x Cursor

More Fable, GPT-5.6 and new ChatGPT voice

Grok x Cursor
Primary source bensbites.com ↗

Published July 9, 2026 · Category: AI Briefing

Overview

Hey folks,

Anthropic extended access to Fable 5 via Claude subscriptions until July 12. Same deal as before: up to 50% of your weekly limits, and after July 12, use prepaid usage credits. But this dangling-a-carrot move doesn’t make me trust their deadlines anymore.

Details

Otoh, OpenAI announced that GPT-5.6 models (Sol, Terra and Luna) will be live for all users later today. General feedback on X (from early testers) is that Sol is not smarter than Fable but is so much more reliable that you would not want to use anything else.

Well, let’s see.

Headlines

  • We have a good Grok model - Grok 4.5. SpaceXAI and Cursor trained it together, and it’s an Opus-class model. It should perform roughly in between Opus 4.7 and 4.8. But it’s much cheaper on a per-token basis and token-efficient—making it 6x cheaper than Opus models and 3x cheaper than GPT-5.5. It’s available in Cursor with increased limits and via API too.

  • ChatGPT Voice is finally getting some new models - GPT-Live-1 and Live-1-mini. A new architecture lets these models a) talk while you’re still speaking without cutting your message off and b) use GPT-5.5 in the background. Results in much smoother conversations and a big jump in intelligence from the old advanced voice mode.

  • A lighter version of Claude Cowork will work on web and mobile - sessions will run remotely and save to your account, so you can kick off a task on the laptop, close it, and check in from your phone. Cowork on the desktop app remains the full deal. Beta rolls out over the coming weeks.

  • Muse Image and Video - New multimedia generation models from Meta. The images have more of an AI look, but the model seems good at image editing and text rendering, and can search the web to get facts right, etc. They also have a video model in preview that will be released soon.
