Measured over 9 original posts from a 30-day window, last computed on October 20, 2026.
Engagement
A typical post picks up 363 interactions against 175K followers, an engagement rate of 0.208%. Measured over 9 original posts, its engagement rate beats 72% of 20,444 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 51K times each, and 0.713% of those impressions turn into an interaction. That is about 29.1% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.9 posts a day over the last 30 days, though only 30% of days saw any activity at all. Most posts go out around 12:00 UTC, and Monday is the busiest day of the week. Of the 9 posts sampled, 56% carry an image or video and 22% link out. The account's strongest tracked post pulled 3.5K interactions, about 9.6x its own typical post.

Compared with accounts its own size
Zephyr's engagement rate beats 72% of the tracked X accounts closest to it in follower count (20,444 accounts, accounts of similar size (decile 9 of 10)). A percentile is spread evenly by construction, so 50 really is the middle of that group and 90 really is its top tenth.
On engagement per impression rather than per follower it beats 34% of the same group. When those two numbers disagree, the gap is about how far its posts travel rather than how people react to them.

At 0.208%, Zephyr sits above the 50th percentile of the 204,694 accounts in this comparison. That places it in the above the median band, which runs 0.143% to 0.677%.

Posting timing
This account posts most often around 12:00 UTC, and Monday is its busiest day of the week. The bars below are the catalog-wide pattern, with this account's own busiest slot marked. They do not show how this account performs at each hour: we keep one aggregate per account, not one per hour, so that measurement does not exist in our data.

Formats this account uses
Its own posting mix on the left, and what each of those formats does across every account we track on the right. Only formats where the effect clears our publish test appear here, so an empty row is a format we could not measure rather than one that does nothing.
| Format | This account | Catalog effect | 95% interval | Accounts behind it |
|---|---|---|---|---|
| Image or video | 56% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 22% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | +15% | +14% to +16% | 32K |
- 56% of this account's sampled posts carry an image or video. Across the catalog, posts with an image or video run 111% above the same accounts' other posts.
- 22% of its posts carry a link off X. Across the catalog, posts with an outbound link run 41% below the same accounts' other posts.
- Its average post runs 365 characters, which falls in the over 280 characters band. Across the catalog, posts over 280 characters run 15% above the same accounts' other posts.
These are catalog-wide differences applied to this account's own posting mix, not a measurement of how each format performs for this account specifically. We keep one median per account, not one per format per account, so the second thing is not something this data can tell you.

I've got a theory Since Anthropic started blocking distillation and patched most exploits Chinese models really slowed down it might be the reason why we haven't seen new releases since GLM 5.3 and Kimi K3.

Looking at the current market mood, it feels like memory is going down either way. Case 1: If they deliver earnings above market expectations: “Isn’t this peak-out? Do you really think these profits are sustainable? Memory is cyclical, and this is the top.” Case 2: If they miss market expectations: “Memory is over now. Even after excluding bonus provisions, they should have easily printed KRW90tn. Sell on news.”

Looking at Muse and Instinct, you really get a sense of how quickly things have progressed since OpenClaw. It feels like only yesterday that Jensen Huang was singing OpenClaw’s praises. Oh, and I’ve heard Meta is renting a massive number of virtual machines for Muse.

ANTHROPIC IPO VALUATION EXPECTATIONS DROP TO ~$1.5T FROM $2T: RTRS Some existing and prospective investors are reconsidering the Claude maker's valuation ahead of its anticipated November IPO, according to Reuters. Anthropic reported Q3 revenue of $16.8B, up 45% QoQ, compared with growth of more than 100% in Q2, when revenue reached $11.6B. Despite reporting adjusted profitability, the slowdown disappointed some investors, with a broader tech selloff and concerns over rising AI infrastructure costs adding pressure. The company has committed to spending at least $518B on cloud computing and infrastructure over the next decade. Source: Reuters.

Reading these numbers
A typical post picks up 363 interactions against 175K followers, an engagement rate of 0.208%. Measured over 9 original posts, its engagement rate beats 72% of 20,444 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 51K times each, and 0.713% of those impressions turn into an interaction.

- What is Zephyr's engagement rate on X?
- Zephyr (@zephyr_z9) has an engagement rate of 0.208%, based on the median interactions across 9 original posts from the last 30 days against 175,075 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.208%, Zephyr sits above the 50th percentile of the 204,694 accounts in this comparison. Those comparison accounts are all large ones, because our scanning cadence is weighted towards big accounts, so this is a ranking among peers of similar scale rather than a ranking across X.
- Does @zephyr_z9 have real engagement?
- Its engagement rate beats 72% of the tracked X accounts closest to it in follower count (20,444 accounts), which puts it in the middle of its size range group. Ranking inside a size band matters because engagement rate falls as accounts grow, so a raw rate would mostly re-measure the follower count. It is a starting point for a look at follower quality, not a verdict on it.
- When does @zephyr_z9 post?
- Most posts go out around 12:00 UTC, and Monday is its busiest day, at roughly 1.87 posts per day across the measured window.
