xAI vs Novita AI: key differences
Novita AI and xAI sell very different things. Novita is a low-cost inference cloud with 200+ open models across text, image, video, speech, voice cloning and embeddings, LLM prices from $0.02 per million, batch at 50% off, and APIs in both OpenAI and Anthropic formats. It also rents GPUs from RTX 3090s to H200s and runs a per-second agent sandbox. xAI sells one closed family, Grok, with Grok 4.6 at $2 in and $6 out, 1M context on Grok 4.20, and native Web Search and X Search.
Budget and breadth favor Novita. It serves the full 1M context on DeepSeek V4 Pro and offers hot-swappable LoRA adapters on dedicated endpoints, so teams can fine-tune and serve open models. Its weak points are looser serverless SLAs, Discord-based support and no public SOC 2 or HIPAA. xAI suits teams that want a closed model with fresh data, though it bills double past 200K prompt tokens and has fewer cloud-marketplace options. Indie products and prototypes lean to Novita. Real-time sentiment and news agents lean to Grok.
What xAI and Novita AI do
xAI
xAI sells the Grok models through its own API. Grok 4.6 is the current flagship and xAI tells developers to use it for everything outside audio, image and video, code included. It has a 500K context window and costs $2 in and $6 out per million tokens under 200K prompt tokens. Older Grok 4.20 and 4.3 models keep a 1M window at $1.25 in and $2.50 out, which is aggressive for that capability class.
Example models: Grok 4.6, Grok 4.20
Full xAI profileNovita AI
Novita AI is a San Francisco inference cloud founded in late 2023 by Frank Lewis and Junyu Huang, and it competes on price and breadth. Its serverless API covers 200+ open models across LLMs, image, video, speech, voice cloning and embeddings, with LLM prices starting at $0.02 per million tokens. The API speaks both OpenAI and Anthropic formats. It became an official Hugging Face Inference Partner in April 2026 and was the day-zero launch partner for Google's Gemma 4.
Example models: DeepSeek V4 Pro, Gemma 4
