DeepSeek's official API serves the current V4.1-Flash and V4-Pro models with 1M-token context and 384K max output, from $0.15/$0.60 per 1M in/out off-peak (Flash) — peak hours bill at 2x, cached input drops to $0.003/M. One key exposes both an OpenAI-compatible and an Anthropic-compatible endpoint, and sign-up grants a free token balance that is deducted before any top-up.

Free 'granted balance' of ~5M tokens at sign-up (deducted before top-ups per official billing rules); $0.70 is an estimate at V4-Flash off-peak rates.

Aion Labs provides specialized fine-tuned models for immersive roleplay and storytelling. Its API is OpenAI-compatible and features a long-term daily free allowance for developers, with higher tiers available upon account top-up.

~40 models offer daily free quotas that auto-refresh the next day (including some Claude/GPT/Gemini models); claims of sign-up bonus and 7-day no-questions refund are platform self-promotion — actual amounts per the console.

BazaarLink is a Taiwan-based AI aggregator providing access to 100+ models via an OpenAI-compatible API. It specializes in TWD billing and unified enterprise invoices. It offers a small signup credit and a persistent free model tier.

Scaleway Generative APIs is a serverless, OpenAI-compatible inference service hosted only in Paris and billed per 1M tokens in euros. Published rates run from EUR 0.15/1M input and EUR 0.60/1M output for gpt-oss-120b, and EUR 0.15/EUR 0.35 for mistral-small-3.2-24b-instruct, up to EUR 1.80/EUR 5.50 for glm-5.2; whisper-large-v3 is metered per audio minute at EUR 0.003 with free output tokens, and embedding models are input-only at EUR 0.10/1M. Every new customer gets a free tier of 1,000,000 tokens, with billing starting at token 1,000,001.

1,000,000 free tokens per new customer, stated on the Generative APIs page; valued at the cheapest published input rate of EUR 0.15/1M (mistral-small-3.2-24b-instruct or gpt-oss-120b), which is roughly USD 0.16 - the grant is token-denominated, so actual dollar value varies by model.

ProRiseHub is a paid top-up relay built on the New API framework, OpenAI-compatible at /v1. Documentation states top-ups are converted at a rate of 1 RMB ≈ $0.15 USD credit, with several dozen zero-priced models.

Mainly paid top-up (1 RMB (≈$0.15) = 1 USD credit); no general signup bonus mentioned; ~51 zero-priced models in /api/pricing.

SambaNova Cloud serves open-weight models (DeepSeek-V3.1, DeepSeek-V3.2, Meta-Llama-3.3-70B-Instruct, gpt-oss-120b, gemma-4-31B-it, MiniMax-M2.7 and MiniMax-M3) through an OpenAI-compatible endpoint at api.sambanova.ai/v1, priced per 1M tokens from $0.22 input / $0.59 output for gpt-oss-120b up to $3 / $4.50 for DeepSeek-V3.1 and V3.2. The free tier is defined by the absence of a payment method: 20 requests per minute, 20 requests per day and 200,000 tokens per day per model, on the five models listed in the free-tier tables. Linking a card moves the account to the Developer tier, which raises per-model limits and caps the account at 20M tokens per day across all models.

Free tier is a recurring daily allowance, not a USD credit: 200,000 tokens/day (20 RPM, 20 RPD) per the official rate-limits docs; 200k tokens at the cheapest published input rate of $0.22/1M (gpt-oss-120b) is about $0.04/day, while the same 200k at DeepSeek-V3.1's $3/1M input rate would be about $0.60/day.
