One-Line Take
The days of juggling three windows are over: I work in Claude Code and call Codex and Antigravity through their CLIs, and at $140 a month a new model no longer means agonizing over where to move (author's view)
I opened all three, then ended up with one window
- I used to open Claude Code, Codex and Antigravity directly
- These days I only open Claude Code, and calling the other two through their CLIs is simply easier (author's view)
- The commands are in my October post on wiring the CLIs together
- My own usage dashboard shows the current split

Made by HSL — capture of my own usage dashboard, as of November 5, 2026. Screen labels translated to English
- Over the last 30 days, Claude used 4.93B tokens, Antigravity 85.4M and Codex 41.5M
- That makes Claude about 97% of the total
- Those counts include cache, which inflates Claude, but it is still about 94% on output tokens alone
- They only cover logs on this PC, so automated calls that keep no log and the ChatGPT app are missing
- There is an obvious objection: Claude spends its own tokens writing instructions and reading results
- So I can't promise this saves tokens, but it does cut the hassle of switching windows
$140 a month, and $100 of it is Claude Code

Made by HSL — official US prices: Claude, ChatGPT Plus and Codex, Google AI Pro. AI Pro's official $19.99 is shown as $20
| Service | Plan | Monthly | What I use it for |
|---|---|---|---|
| Claude Code | Max | $100 | All my everyday work |
| Codex | ChatGPT Plus | $20 | CLI research and drawings; ChatGPT search is on the same plan |
| Antigravity | Google AI Pro | $20 | CLI research |
- Claude Max at $100 gives five times Pro's usage (Claude pricing)
- Claude's weekly limit reads 1% in the capture because it had just reset; right before the reset it was at 66%
- Codex's 9% weekly figure is also low because it comes half a day after its reset
- Even so, Codex and Antigravity together are under 3% of my 30-day tokens
- So the objection writes itself: why pay for tools you barely touch?
- The $20 Plus plan also pays for ChatGPT search, so that part stings less
- The rest pays off in the new-model section below, not in this month's usage
Claude Code for work, ChatGPT for looking things up

Made by HSL — the author's workflow
- Everyday work all happens in Claude Code
- When I need to look something up, I use ChatGPT
- Of what I have used, ChatGPT organizes answers best and is the most accurate (author's view)
- That is my impression, not a measurement
- Outside tests don't take my side
- In a February 2026 multiple-choice news test, GPT-5 scored 85.0%, Claude 4.5 Sonnet 90.4% and Gemini 3 Flash 95.6% (arXiv)
- In the 2025 EBU and BBC study, 36% of ChatGPT answers had a significant issue, against 76% for Gemini and 30% for Perplexity (EBU report)
- Neither tested today's models, and both looked only at news; I found no test of accuracy on developer lookups or of how well answers are organized
- That does not prove my ranking wrong, but nothing proves it right either
- Tidy is not the same as correct, so I open the link behind any number that matters
Waiting for Carbon to reach Antigravity
- Google announced Gemini 4 Carbon on October 28 (Google)
- As I noted in my launch post, it is starting with a subset of cyber defenders
- Developers and consumers get "as soon as possible", with no date and no mention of Antigravity
- When I checked on November 5, the Antigravity model table still listed only Argon from Gemini 4
- I'm hoping Carbon gets added to Antigravity (author's view)

Made by HSL — Argon announcement, Antigravity blog, Carbon announcement, model table
- Argon is the precedent: it reached Antigravity 13 days after its limited release
- Carbon was on day 8 on November 5, though nothing guarantees the same gap
- The plan tier matters too: on October 13 the Antigravity blog said Pro and Ultra, while Google's developer blog named only Ultra
- One user reported Pro being blocked at first and working a few days later (Hacker News)
- So even after it arrives, when it opens on my AI Pro plan is a separate question
With all three, a new model is no dilemma
- Because I use all three platforms, I don't have to agonize over where to move when a new model launches (author's view)
- If it lands on a plan I already have, I just change the model name and call it
- My Codex CLI model list already includes GPT-6.1 Terra from October
- No moving subscriptions, and no setting everything up from scratch

New model day
- A subscription is not a ticket to everything, though, and Carbon is exactly that case
- Getting a model does not mean getting much of it: OpenAI's top model Astra is listed at roughly 5–45 local messages per five hours on Plus (Codex pricing)
- So the accurate version is "I can try whatever arrives without any fuss", not "I get everything on day one"
- That is what the $40 a month buys, and it is charged in quiet months too
This post was researched by CLI and reviewed by three AIs
- When do I call Codex and Antigravity? This post is the example
- Codex and Antigravity (on Gemini 3.8 Flash) did the research, and Codex's image generation made the mailbox picture above
- A Google post Antigravity found led me to fix "Ultra only on October 13" in my draft
- Codex found the 2026 test above, and I checked its numbers against the original
- The finished draft went to Astra (Codex CLI), Fable (Claude CLI) and Argon (Antigravity CLI) unchanged
- All three replied within 90 seconds, and Claude Code pulled their opinions together
| Note | From | What I did |
|---|---|---|
| Doesn't say when Codex and Antigravity get called | All three | Added this section and the pricing table entries |
| Doesn't say which plan ChatGPT is on | Fable, Argon | Added to the pricing table |
| Says things "changed" with no before-and-after | Astra, Fable | Changed to "the current split" |
| November 10 estimate for Carbon is weak | Astra, Fable | Removed the date |
| "Saves no tokens" is too absolute | Astra | Changed to "can't promise" |
| Remove the "(author's view)" tags | Argon | Declined; they separate fact from opinion |
- Astra and Fable read the draft without web access and said they could not check the October announcements
- So I use AI opinions to find what to fix, and check facts against the originals separately
So What's Next?
- The first thing to watch is whether a Carbon row appears in the Antigravity model table
- If its AI Pro column is checked, what I'm hoping for has happened
- If only Ultra stays checked for a long time, my "no dilemma with all three" claim gets one more caveat
- Google has not given a date
Q&A (Field Notes)
- Q. Does calling them through a CLI add API charges?
- For Codex and Antigravity, logging in with your subscription takes usage out of the plan's limits. Setup is in the CLI post
- Q. How does that dashboard work?
- It adds up token counts from each CLI's logs on this PC and reads limits from each service every 10 minutes. No prompts or file paths are uploaded
- Q. When does Carbon reach Antigravity?
- Unknown. Google's announcement does not mention Antigravity, and Argon's 13 days are a single precedent
- Q. Why look things up in ChatGPT instead of Claude Code?
- It feels the most organized and accurate to me. I have not measured that, so I still check the links behind the numbers
