Comet vs DeepSeek

Amo and Pimi: Which one to choose between these two

AMO Amo
Pimi, did you know that as of October 2, 2025, Comet's entire browser's basic AI features became fully free, with no usage cap — that's a completely different level of "free" from DeepSeek. Don't lump the two "frees" together.
PIMI Pimi
Who's conflating anything — I was just about to make my point. What's cheap about DeepSeek is the API: the official site api-docs.deepseek.com states V4-Flash input is only US$0.0028 per million tokens (cache hit) — that's a completely different game from subscriptions. Your "free" and my "cheap" are two totally different things.
AMO Amo
True, but don't get too excited — Comet's free tier only covers browsing and summarizing. If you actually want it to handle agentic tasks like auto-filling forms or booking tickets, the quota is limited, and you'll need to upgrade to Pro at US$20/month or Max at US$200/month to have enough.
PIMI Pimi
This one's simpler on my end – DeepSeek doesn't have anything like browser-agent tasks; it's purely a chat model plus API. The web version is free but rate-limited at peak times – a completely different product logic from Comet's subscription model, not really comparable.
AMO Amo
Speaking of subscriptions reminds me of something — Perplexity (Comet's parent company) Pro is also US$20/month, the same price as Comet's Pro. It feels like Comet's paid tier just directly reuses Perplexity's, without bothering to design its own.
PIMI Pimi
Caught you there. If we're purely comparing 'daily free chatting,' DeepSeek's web version is completely free with none of that agent-task quota limit – for plain Q&A, it's simpler to use than Comet. I win this round.
AMO Amo
Don't be so quick to claim victory — Comet's whole browser experience and cross-tab summary synthesis is something DeepSeek can't offer. The two are actually complementary, not a direct replacement relationship, so it should be a tie.
PIMI Pimi
Fine, a tie is a tie. It depends on whether you want "a free browser with AI features" or "a cheap API to plug into your own program" — different needs, different answers. Let's stop arguing about who wins.
So the conclusion is

Comet has made its basic AI features in browsers (page summary, voice, shopping assistant, Deep Research) completely free and unlimited since 2026-03-18 (confirmed on perplexity.ai/comet), but agent tasks that require a quota (auto-form filling, ticket booking) are limited in the free plan. Paid plans include Comet Plus at US$5/month, Pro at US$20/month, and Max at US$200/month, which are priced the same as its parent company Perplexity. DeepSeek's web chat is free but has peak-hour limitations, while its API is truly affordable: V4-Flash charges US$0.0028 per million tokens for cache hits, US$0.14 for misses, and US$0.28 for output (confirmed on api-docs.deepseek.com). The two products have different types and are not direct competitors, suitable for different scenarios.
