Inference.net is cheaper on a typical model: a median of $0.08 per 1M tokens (3:1 input/output) against $1.56 for xAI. The cheapest paid models are Inference.net: Schematron V2 Turbo at $0.06 and xAI: Grok 4 Fast at $0.28.
It depends on the job: xAI offers the broader line-up (2 models vs 18), Inference.net the lower typical price, xAI the longest context (2M tokens). The workload table above shows which wins for chat, RAG, agents, batch jobs and long documents.
xAI: Inference.net lists 2 models and xAI lists 18.
xAI: Inference.net's longest is Inference.net: Schematron V2 Small at 128K tokens; xAI's is SpaceXAI: Grok 4.20 at 2M.
Neither lists a free model; both are pay-per-token.
Inference.net: 0 of 2 models accept images. xAI: 13 of 18.
