What changed

Perplexity updated the model list on its Computer and Pro plans, renaming the GPT-6 Sol entry to GPT-6.1 Sol. Pulse detected the change on Sep 30, 2026. One day earlier, the same lineup's Claude Sonnet 5 entry was upgraded to Claude Sonnet 5.5. Price, credits and plan limits were unchanged.

Why it matters

For a product leader evaluating AI-feature bundling, this is a reminder that the "model" behind a seat is not a fixed spec — Perplexity swaps the underlying model name on its Pro and Computer plans whenever a provider ships a new version, without changing what a seat costs or includes. If you're building a competing product with named models as a selling point, expect your own model list to need this kind of routine refresh, and budget for the support and messaging cost of explaining a model-name change to customers who don't know the difference between "GPT-6 Sol" and "GPT-6.1 Sol." Watch whether Perplexity ever pairs one of these swaps with a price or credit change — that's the point where a model refresh becomes a packaging decision instead of routine maintenance.

In context

Per Pulse's record, Perplexity has made eight real pricing-page changes since tracking began on Jul 6, 2026. This is its second model-list swap in two days, after the Claude Sonnet 5 to Sonnet 5.5 upgrade on Sep 29, 2026 and the GPT-5.6 Terra to GPT-6 Sol swap on Sep 23, 2026. None of these moves touched price, credits or seat limits — Perplexity's Pro and Computer plans keep the same cost while the model names churn underneath them. For a product leader, the real signal is that a company willing to reshuffle its AI roster this often treats the model list as a marketing surface, not a pricing lever — making it easy to miss the day a genuine price or limit change rides along with one of these swaps. Watch whether that day comes, or whether Perplexity keeps the roster and the price permanently decoupled.

Common questions

Why would a company swap an AI model name without changing price?

Underlying AI providers like Anthropic ship new model versions on their own schedule, and Perplexity's recent history shows it updates its model list to match almost as soon as a new version ships, without touching what the Pro or Computer plan costs.

Could my own product face this same kind of change from a model vendor?

Yes — if you build your plan descriptions around a specific model name rather than its capability, expect to update that name whenever the vendor ships a point release, as Perplexity has repeatedly done this year.
