HyperAgent (hyperagent.com) — fleet-of-AI-agents platform (research, docs, sites, decks, video). Plans convert monthly price 1:1 into spendable credits (up to 45% bonus); agents draw on hosted LLMs (Claude, ChatGPT, Kimi, etc.). Unofficial browser/cookie integration.

Every dollar of plan price returns as credit (1 credit = $1 of model spend); higher tiers add 10-45% bonus. Pay-as-you-go discontinued Aug 2026; top-ups via credit blocks.

OpenAI Codex is the coding agent that runs across ChatGPT, an IDE extension, the CLI and cloud environments on a single ChatGPT account, with cloud worktrees, scheduled background tasks, Skills and code review. The Codex pricing documentation lists Free at $0/month for "quick coding tasks", Go at $8/month, Plus at $20/month, Pro from $100/month, Business at $20/user/month billed annually ($25 monthly, minimum 2 users) and Enterprise/Edu by contact, plus an API-key route billed at API rates. Usage is measured as messages per five-hour period that vary by model: on Plus, the documented ranges run from 250-2,000 messages for GPT-5.6 Luna down to 5-45 for GPT-6 Astra, and OpenAI states these are estimates rather than fixed limits.

Codex Free is $0/month, described as "Explore Codex capabilities on quick coding tasks"; no fixed free message count is published (Codex pricing docs, checked 2026-09-16).

Open-source Go proxy server (MIT license, router-for-me/CLIProxyAPI) that wraps CLI subscriptions - Google Antigravity/Gemini, OpenAI ChatGPT Codex (GPT series), Anthropic Claude Code, xAI Grok Build, Moonshot Kimi - and exposes them as OpenAI (incl. Responses), Gemini (incl. Interactions), Claude, Codex and Grok compatible API endpoints. OAuth login flows, multi-account round-robin load balancing, streaming/non-streaming/WebSocket, function calling, multimodal input, Management API, and an embeddable Go SDK. Self-hosted; users bring their own upstream accounts/keys. Desktop wrapper: EasyCLIProxyAPI.

Software is free (MIT); access to upstream models depends on user-provided subscriptions/API keys, no credits or prices from the proxy itself.

web-cookie access — wraps the provider web app (unofficial). Paste the full ChatGPT Cookie header. OmniRoute verifies it in an isolated headless browser profile. 93 models tracked (via OpenRouter catalog).

A free tier is available; the exact credit value is not quantified.

ChatGPT's free tier is available to everyone and is described on the official pricing page as unlimited text chats with GPT-5.6 Luna subject to abuse guardrails, with limited messages when uploading files, limited and slower image generation, limited voice chats, limited deep research, limited memory and context, limited Codex access and limited ChatGPT Work access on desktop. Paid plans are priced per user per month at $8 (Go), $20 (Plus) and $200 (Pro) as announced by OpenAI on 16 January 2026, with Business and Enterprise offered monthly or annually.

No free credit or USD allowance is stated for ChatGPT on the official pricing page or the ChatGPT Go announcement (checked 2026-09-16); the free tier is a feature-limited plan, not a credit.
