Chatgpt vs Perplexity

OpenAI officially lists ChatGPT Free, Go, Plus, Pro, Business, and Enterprise. The official pricing page rendered US-dollar amounts on 2026-10-01: Free $0, Go $8/month, Plus $20/month, and Pro $100/month, billed per user per month; Business and Enterprise pricing is sales-assisted. Pro includes Pro reasoning powered by GPT-6 Astra.

Official OpenAI sources confirm consumer and business plan availability. OpenAI's terms state that, as between the user and OpenAI and to the extent permitted by applicable law, users retain Input ownership and own Output. OpenAI's data controls documentation should be consulted for consumer training controls; business products and the API are covered by separate business-data commitments. 2026-09-03 watch: OpenAI released GPT-6 Astra. Official Path to Astra post (https://openai.com/index/path-to-astra/, 2026-09-01) designates Astra as the first model at Critical cybersecurity capability; advanced cyber workflows are limited at launch to trusted testers / Daybreak Blue. Axios reports limited Daybreak Access first, then ChatGPT Plus / Pro / Business / Enterprise and API developers in the coming days. This is not a new ChatGPT SKU. Plus/Pro plan prices were not confirmed as changed on 2026-09-03 and were not re-verified as dollar amounts on this date. Re-verified 2026-10-01: the official pricing page now exposes US-dollar amounts for Go ($8), Plus ($20) and Pro ($100), which the 2026-08-25 check could not retrieve and therefore left unreported. GPT-6 Astra is still presented as an included feature of Pro rather than a separate consumer SKU.

Official support lists Standard/Free, individual Pro, individual Max, Enterprise Pro, and Enterprise Max. Max includes everything in Pro plus the highest access to advanced models, Comet Max Assistant, Create files and apps, and Brain. The reviewed public consumer-plan pages did not expose current Pro or Max dollar prices. An official organization-onboarding article lists Enterprise Pro at $40/seat monthly or $400/seat annually.

Perplexity is documented as an AI-powered answer/search product with citations, premium models, file uploads, Research, Create files and apps, Comet, and Computer features depending on plan. AI Data Retention is enabled by default for Free, Pro, and Max users and can be turned off for future collection; previously collected training data is not removed by a later opt-out. Enterprise data is not used for AI training, and Perplexity says its third-party model-provider agreements prohibit provider training on Perplexity data. Consumer terms warn that output may be subject to third-party model licenses and use restrictions. 2026-09-02 official blog “Optimizing On-Device Inference for Apple Silicon” (https://www.perplexity.ai/hub/blog/optimizing-on-device-inference-for-apple-silicon): Lily is a lightweight local inference engine built specifically for Apple silicon and Qwen3.6-35B-A3B so on-device compute does not bottleneck Hybrid Compute / Perplexity Computer tasks. Official facts from that post: Rust runtime; OpenAI-compatible chat-completions API; custom Metal kernels; neither PyTorch nor MLX in the execution path; standalone demo on GitHub. The official pplx-garden README names the demo at https://github.com/perplexityai/pplx-garden (lily/), Apache-2.0, greedy generation for the Qwen3.6-35B-A3B MLX affine 4-bit checkpoint format, Apple GPU family 10 or later (M5 and newer). Lily is not a new paid Perplexity plan SKU. Consumer Pro/Max dollar prices were not re-verified on 2026-09-02. Re-verified 2026-10-01: the official plan-comparison article still routes consumer Pro and Max to the app rather than publishing dollar amounts, and lists Education Pro at $10/mo with SheerID verification. Enterprise Pro is stated as starting at $40/month or $400/year per seat, matching the 2026-08-25 record.
