NVIDIA NIM's hosted API (build.nvidia.com / integrate.api.nvidia.com) serves a broad catalog of open-weight models — Nemotron, Llama, Qwen, DeepSeek, GLM and more — in an OpenAI-compatible shape, with a permanent free tier: API key at sign-up, no card, 40 requests/minute by default (200 RPM granted on request, per NVIDIA's developer forums).

Free tier is rate-limited (40 RPM default, 200 on request) rather than credit-based — no USD value to quantify.

Naga.ac is a unified AI aggregator providing access to over 240 models via one OpenAI-compatible API. It offers a free tier with 100 requests per day and a pay-as-you-go model with competitive rates, occasionally lower than direct provider pricing for select models.

Nebius sells two products relevant to an API-pricing decision: Token Factory, an OpenAI-compatible inference API for open models (where each model is offered in a default and a -fast flavor with different latency and token pricing), and GPU instances billed per GPU-hour, from $2.15 for preemptible H100 up to $7.85 on-demand for HGX B300. The public pricing page documents instance, storage and network rates plus billing rules; Token Factory per-token prices are only shown after login. Commitment reservations are advertised at up to 35% below on-demand rates.

No free tier or USD sign-up credit is stated on official pages (checked 2026-09-16); the docs describe promo codes that grant free credits only when Nebius issues one in a special offer, and the first card payment is $25 credited to the account balance.

Ollama (ollama.com) is primarily a local runtime for open models - the ollama.com pricing page lists a Free plan at $0 whose first feature is "Run models locally" and states plainly that "Local models are always free" - and it also operates a cloud API for models too large for local hardware. The cloud side is priced per million tokens with a published table (for example gpt-oss:20b at $0.07 input / $0.30 output, gemma4 at $0.14 / $0.40, deepseek-v4.1-flash at $0.15 / $0.60 and kimi-k3 at $3.00 / $15.00), with higher peak pricing between 12:00 and 18:00 UTC Monday to Friday.
