AI API Router Directory

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.

Inner AI (innerai.com / app.innerai.com) is a multi-model AI productivity app (chat, image/audio/slide generation, custom assistants). Access via this route is an unofficial web-cookie integration (token cookie + account email). Official pricing page documents Lite and Pro plans with GPT-5 Mini/DeepSeek 3.1 +5 fast models, GPT-5/Claude 4.6 Sonnet +5 advanced models, and credit-based generation (Nano Banana, ElevenLabs, Gamma +25). Third-party sources report a 7-day free trial/money-back guarantee rather than a perpetual free tier.

Derived: Pro plan ($15/mo) includes 10,000 monthly generation credits (pt innerai.com/pricing) -> ~$0.0015/credit.

Weights & Biases Serverless Inference gives API and playground access to open-source LLMs hosted on CoreWeave, using an existing W&B account and no separate provider keys, with support for bringing your own LoRA weights for fine-tuned models. Token rates are listed per 1M tokens on the W&B pricing page: Meta Llama 3.1 8B at $0.22 input / $0.22 output, Meta Llama 3.3 70B at $0.71 / $0.71, OpenAI GPT OSS 120B at $0.03 / $0.17, NVIDIA Nemotron 3.5 Lightning at $0.07 / $0.20 with a $0.04 cache-hit rate, and DeepSeek V4-Pro at $1.15 / $2.55 with a $0.20 cache-hit rate. Inference spend is separate from platform subscriptions and can be capped with a monthly W&B Inference budget.

Weights & Biases states only that Inference includes 'Free credits for a limited time' on the Free plan and a $5/mo credit on Pro, with no dollar amount or expiry published for the free grant (checked 2026-09-16).
