Claude Opus 5.5 与 OpenAI GPT-6 Luna、Sol 同期发布

82 Share Hi folks, Keshav here. Ben’s travelling today, so you’re stuck with me.

We have three new models to talk about:

Claude Opus 5.5 - it’s the “one model to rule them all” at this moment. Better than Fable 5.1 on benchmarks, cheaper than Opus 5, writes extremely well, and reliable in the tasks you give it.

With the release of Opus 5.5, the five-hour limits in Claude Code are increased by 20% and we’re getting a banked rate limit reset .

The default thinking level for Opus 5.5 is medium in the app. Ben likes that too. I’ve been running it at high/xhigh for the last two days and I only hit the 5 hour limit once.

I asked it to work on a few side projects:

ossean.com - “update filtering with jev instead of gemini and redesign the website a little bit”

shortandlongtail.com - “rewrite the essays with detailed research”

detroitbench - “run the three new models and add them to the results”

Every says it’s pulling their Codex converts back to Claude and I feel the same. My go-to agent has changed to Claude Code with this release.

GPT-6 Luna and Sol from OpenAI . There’s no Terra this time. Don’t think anyone was even using it. Both GPT-6 Luna and GPT-6-Sol are only available in Codex and ChatGPT Work (not regular chat) for now.

Key part: both of them are 50% cheaper than their previous versions. That’s $0.10/$0.50 for Luna and $2/$10 for Sol, per million input/output tokens. Both models come with only a minor upgrade in intelligence. GPT-6-Sol is clearly a step behind the new Opus model.

I wanted to put the price cuts for Sol to test so I sent it on a long task to create a duolingo like course for marketing.

Keshav Jindal @Keshavatearth let's see what comes out on the other end. Ananyaa Gupta @Momosdo Forget Spanish.

In about 4 hours, it consumed 22% of my weekly limits on a $100 Codex plan. Here’s what it built .

GPT-6-Astra consumes limits wayy too fast. I need to play more with Astra driving Sol subagents but it seems like a reasonable thing to try.

Ben’s Bites is brought to you by Adobe Acrobat

Adobe for Claude just got a major upgrade: Acrobat tools now join Adobe's creative tools in one plugin, unlocking 80+ pro-grade tools across imaging, design, video, and documents. New interactive editors let you hands-on edit PDFs and Adobe Express designs directly inside Claude .

Muse at Meta Connect - Zuckerberg is going all in on Muse, Meta’s personal AI assistant. It can now use any app on your Mac, buy for you via Walmart, Best Buy & Sephora and it’s getting its own email address so you can CC it on threads. It’s also coming to Meta’s glasses in the next few months.

Zuck says Muse stays free for “a huge number of tokens” but Meta might take a small fee from transactions. Also coming: a video-chat avatar for your Muse and a Tamagotchi-like keychain to carry Muse around (welcome back AI pendants).

Gemini 3.8 Flash and Flash-Lite TTS - new speech generation models from Google. Half the price of 3.1 Flash TTS, 100+ languages and 2000+ voices to pick from. Plus you can clone your own voice too. Steve (Tldraw’s founder) is impressed with these models , so that’s some signal.

ChatGPT Voice can now use your email, calendar and Slack and pair up with Astra, Sol or Luna models to optimize for intelligence/cost.

Claude found a new enzyme system in bacteriophage DNA (viruses that infect bacteria). Nobody knows what it does yet, and reruns of the same search missed it . Weren’t we pacing the frontier, eh?

i still remember when opus 4.5 was my favorite model to talk to in openclaw, and opus 4.6 was my favorite for writing.

then everything changed.

until today. opus 5.5 is the most comfortable model i've written with since 4.6. not even fable gave me that. 10:53 PM · Sep 22, 2026 · 104K Views 27 Replies · 46 Reposts · 911 Likes Find me on X , Linkedin , or YouTube
