AI API Router Directory

Mistral's La Plateforme is a first-party EU-based API with per-1M-token pricing, a 50% batch discount and up to 90% cached-input savings. The free plan includes $10/month of API credits plus Vibe and Studio access; Pro ($14.99/mo) raises that to $30/month. Open-weight models are available for self-hosting (Apache 2.0 for research/individual; commercial use requires a Mistral license).

Community reported approximate monthly value of the Experiment free tier for developers.

AI/ML API is a major AI model aggregator providing unified access to 1000+ models from OpenAI, Anthropic, Google, DeepSeek, and more. It offers a single API key for LLM, image, voice, and video models with a focus on production-ready pay-as-you-go access.

Clarifai provides a production-ready AI API for developers, offering an OpenAI-compatible endpoint to run inferences on Clarifai-hosted models from labs like Meta, Google, and Mistral, alongside their own specialized vision and NLP models.

IBM watsonx.ai is an enterprise AI studio combining machine learning, decision optimization and generative AI, with an Essentials pay-as-you-go plan starting at USD 0/month and a Standard plan starting at USD 1110/month. The free Toolbox playground includes up to 300,000 foundation-model tokens per month, up to 20 compute usage hours (CUH) per month and up to 100 text-extraction documents per month. Model usage is metered per million tokens, for example granite-4h-small at USD 0.0636 input and USD 0.265 output, with all IBM and third-party embedding models at USD 0.10 per million tokens.

The free Toolbox playground grants up to 300,000 foundation-model tokens, 20 compute usage hours and 100 text-extraction documents per month; IBM publishes no USD-denominated credit on the official pages fetched, so no dollar value is asserted.

Lambda sells NVIDIA GPU cloud rather than a token-metered API. Self-serve instance pricing is per GPU-hour: NVIDIA B200 SXM6 at $6.69, H100 SXM at $3.99, A100 SXM 80GB at $2.79, A100 SXM 40GB at $1.99, GH200 96GB at $2.29, A10 at $1.29, A6000 at $1.09 and Tesla V100 at $0.79, all plus applicable sales tax/VAT/GST. 1-Click Clusters scale from 16 to 2,000+ GPUs on 2-week-to-1-year terms at $8.87-$9.86 per GPU-hour for HGX B200 and $5.54-$6.16 for H100. Lambda's own Inference API is being retired: the official page states that "as the Inference API winds down" customers should continue by deploying and scaling models on NVIDIA GPU instances.

No free tier stated on official pages (checked 2026-09-16): lambda.ai/pricing lists only per-GPU-hour instance and cluster rates plus tax, with no trial credit or free allowance.

Snowflake Cortex AI runs LLMs, agents and search inside the Snowflake governance perimeter, exposed through SQL AI functions, Cortex Agents, Cortex Analyst and Cortex Search. It bills on a second credit type: AI Credits, priced at $2.00 per credit on demand globally and $2.20 regionally (Snowflake Service Consumption Table, effective 2026-09-09), on top of Platform Credits for warehouses. Published AI Credit rates per 1M tokens include llama3.1-8b at 0.11 in / 0.11 out, llama3.3-70b at 0.36 / 0.36, mistral-large2 at 1.00 / 3.00, and claude-sonnet-5 at 1.30 / 6.50 when invoked via Snowflake CoWork or Cortex Agents; Cortex Search is 6.3 AI Credits per GB per month of indexed data and Cortex Analyst is 67 Platform Credits per 1,000 messages.

Snowflake markets a free 'start for free' signup but no dollar credit amount or free Cortex allowance is stated on the official pricing page or consumption table (checked 2026-09-16).

TokenRouter (tokenrouter.com) is an AI model API aggregator providing a unified gateway to multiple frontier LLMs. It exposes an OpenAI-compatible endpoint for integration with standard SDKs and tools.
