TL;DR

OpenAI rate-limits aggressively; LLM data collection needs massive proxy pools. Bright Data leads (14 of top 20 LLM labs use them per 2025 disclosure). For smaller AI projects, GProxy or Oxylabs work. We rank 8.

Why they are looking for an alternative

Two use cases: (1) Accessing ChatGPT API at scale through region-specific proxies or to bypass rate limits — needs residential or ISP. (2) LLM training data collection — large-scale web crawling for training corpora — needs massive residential pools.

For LLM training data

You need petabyte-scale residential infrastructure. Bright Data is the de-facto standard (14 of top 20 LLM labs). Oxylabs is the second choice. Other providers are usable but at smaller scale.

For ChatGPT API access (bypassing rate limits, geo-restrictions)

Smaller scale, budget-driven. GProxy residential PAYG ($0.85/GB) or IPRoyal ($1.75/GB) work for individual developers. SOAX mobile for stricter rate limit avoidance.

Methodology

For each provider we visited their public product/pricing page on 2026-05-16, recorded the lowest published price, the disclosed network size (with the caveat that "number of IPs" claims are vendor-self-reported), and noted unique product offerings. We did NOT include affiliate codes, kickbacks, or per-conversion sponsorship in this ranking. GProxy is the publisher; we rank ourselves where the data supports it and concede other providers' wins where the data supports them.

FAQ

Do LLM labs really use Bright Data? +

Per Bright Data's 2025 disclosure, 14 of the top 20 LLM training labs use their infrastructure. This is one of the few proxy company customer claims with public corroboration (their LLM customers have referenced Bright Data in technical reports).

What proxy type for ChatGPT API? +

Residential or ISP. Datacenter often flagged. Mobile (SOAX, IPRoyal) for highest success but expensive.

Can I bypass OpenAI rate limits with proxies? +

Proxies rotate your IP but don't change your API key. OpenAI rate-limits per API key, not per IP. Proxies help with IP-based blocks (regional access, repeated browser-based ChatGPT use) but not API key rate limits.

Total

For LLM training: Bright Data is the industry standard (14 of top 20 labs). For ChatGPT API access at developer scale: GProxy residential PAYG $0.85/GB or IPv6 from $0.03/proxy. For mid-budget AI teams: Smartproxy or Oxylabs.
