Azure OpenAI (Microsoft Foundry) serves the GPT family per 1M tokens in three priced deployment scopes — Global, Data Zone (EU/US, +10%) and Regional (up to 27 regions): GPT-5.6 Sol $5/$30 (short context, Global), Terra $2/$12, Luna $0.20/$1.20, gpt-oss-120b $0.15/$0.60. Batch (−50%) and PTU reservations (from $1/PTU/hr Global) sit under the same account; new Azure accounts carry a $200/30-day trial credit.

New Azure accounts: $200 credit for 30 days (stated on the Azure OpenAI pricing page; Azure-wide, applicable to Azure OpenAI — verified 2026-09-16). No standing free tier beyond it.

Feifeimiao (api.feifeimiao.top) is a Chinese third-party relay service offering an OpenAI-compatible API gateway. Built on the New-API framework, it aggregates various models and focuses on providing access to tools like Codex and Claude Code for developers in the region.

$10 trial credit on signup; promotional $20 weekly-limited cards for new and existing users (weekly expiry). The core is paid subscriptions (Small ¥60 (≈$8.93)/30d ≈ $20/day, Medium ¥150 (≈$22.32)/30d ≈ $60/day).

FreeModel is a multi-model gateway that intelligently routes requests to the best-performing open models. It supports both OpenAI and Anthropic API formats and provides automatic model fallback and smart provider selection to optimize for quality.

Signup credits land instantly, no card. Community reports conflict: $10 signup credit (phone/Telegram verify) up to claims of ~$66/week (~$300 cumulative) - authenticity unconfirmed. Conservative: $10.

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.

OpenAI Codex CLI — OpenAI's terminal coding agent (also web/IDE). Authenticates via ChatGPT OAuth or an API key. Model lineup (as of mid-2026): GPT-6 Astra, GPT-5.6 (Sol/Terra/Luna), GPT-5.5, GPT-5.4 / 5.4 mini, plus gpt-oss-120b; GPT-5.3-Codex-Spark is a Pro-only research preview. Plans: Free, Go ($8), Plus ($20), Pro 5x ($100) / 20x ($200); API-key mode is pay-as-you-go at API rates.

ChatGPT plans use credit-based usage allowances (credits per 1M tokens, e.g. GPT-5.6 Sol 100/10/500); not a fixed $ credit value. API-key mode billed at standard OpenAI API token rates.

Poe is Quora's multi-model chat product that aggregates GPT, Claude, Gemini, Grok, Kimi and image/video/audio bots behind one subscription and one points balance rather than separate provider plans. Official subscription plans are annual: $49.99/year ($4.17/month) for 10 thousand points per day, $199.99/year for 660 thousand points per month, $499.99/year for 1.65 million, $999.99/year for 3.3 million and $2,499.99/year for 8.25 million points per month, with an add-on rate of $30 per 1M points that subscribers can buy for API or one-off use. Non-paying users receive points daily that reset every 24 hours and never roll over; Poe's help centre states subscriptions start at $4.99/month.

Poe gives non-paying users daily compute points that reset every 24 hours, but no official page fetched states the daily quantity, and poe.com/pricing returns 404, so no dollar value is claimed (checked 2026-09-16).
