Perplexity flips its Pro model lineup back to Grok 4.7, a day after swapping it out
Perplexity's Pro plan model lineup added Grok 4.7 (xAI) and removed Claude Haiku 5.5 (Anthropic) on October 9 — the exact reverse of an October 8 change that had added Haiku 5.5 and removed Grok 4.7.

WHY IT MATTERS
For buyers comparing AI assistants on model access, a lineup that changes daily undercuts the point of comparing "what's included" at all. Watch whether Perplexity settles on one of the two models in the next few days, or whether a third swap follows — which would point to an active test rather than a settled roster call.
BY THE NUMBERS
- Reverses an Oct 8 change that added Haiku 5.5 and dropped Grok 4.7
- 9 of Perplexity's 10 tracked changes since July are model-lineup swaps
- Perplexity leads the index with 6 feature changes in the last 180 days
- Changes land every ~10 days on average; these two landed a day apart
THEIR RATIONALE
Perplexity frames these as routine roster refreshes rather than strategic repositioning: nine of its ten tracked pricing-page changes since July have been model-lineup swaps, the same kind of churn seen when GPT-6 Sol became GPT-6.1 Sol or Gemini bumped to 3.8 Flash. But swapping the same two models back and forth within 24 hours is new — every other update in its history has moved in one direction and stuck.
THE SIGNAL
Feature changes are the single most common event type across the Pulse Index — 182 of them across 156 companies in the last 180 days — and Perplexity is the most frequent company in that group with 6. Still, flipping Grok 4.7 and Claude Haiku 5.5 in and out within a day looks less like a deliberate model refresh and more like an unresolved call about which model belongs in the Pro tier, or a live comparison playing out on the pricing page itself.
IN CONTEXT
Perplexity's Pro lineup churns constantly — nine of its ten tracked pricing-page changes since July have been model substitutions, including GPT-6 Sol swapped for GPT-6.1 Sol on Sep 30 and Claude Sonnet 5 upgraded to Sonnet 5.5 on Sep 29. What's unusual here is the direction: this change undoes Oct 8's swap, which had added Claude Haiku 5.5 and removed Grok 4.7 — the exact opposite of today's move. Perplexity is already the most frequent feature-changer in the index, but flipping the same two models back and forth within 24 hours is new even for it.
