Lepton AI vs Together AI: Pricing, Specs, Strengths & Weaknesses
Side-by-side comparison of GPU compute pricing, regions, billing models, and strengths for Lepton AI and Together AI. Rates sourced from public APIs — verify current availability and billing terms before purchasing.
Overview
Strengths & Best For
Lepton AI is now part of NVIDIA and operates as NVIDIA DGX Cloud Lepton, a platform for accessing and managing AI infrastructure at scale. Originally a serverless AI platform, it has been integrated into NVIDIA's broader DGX Cloud ecosystem, giving teams access to NVIDIA-managed GPU infrastructure through a unified platform. Teams building on NVIDIA's ecosystem should evaluate DGX Cloud Lepton alongside other NVIDIA cloud offerings.
- NVIDIA-managed infrastructure
- DGX Cloud ecosystem integration
- Pythonic SDK
- Competitive spot pricing
- Absorbed into NVIDIA DGX Cloud — roadmap and pricing tied to NVIDIA enterprise sales cycle
- Less suitable for teams outside the NVIDIA ecosystem
- Self-serve on-demand access limited compared to independent GPU clouds

Together AI is a full-stack AI platform combining a high-throughput inference API (200+ open-source models), dedicated GPU clusters (H100 SXM, A100), and a managed fine-tuning service. Together MoE optimization cuts costs on large mixture-of-experts models. Function calling and JSON mode across all major models. Fine-tuning: LoRA and full fine-tune for Llama, Mistral, and Qwen. GPU cloud: H100 SXM and A100 clusters for large-scale training. Check api.together.ai/models for current per-token rates.
- 200+ open-source models — wide inference API catalog
- Llama 4 Scout — competitive frontier-open pricing
- Together MoE optimization reduces cost on large MoE models
- Managed fine-tuning: LoRA and full fine-tune for Llama, Mistral, Qwen
- Function calling and JSON mode across all major models
- GPU cloud + inference API from one vendor
- GPU cloud side less polished than pure-play providers like CoreWeave
- Inference API latency trails Fireworks and Cerebras on speed benchmarks
- Enterprise SLAs require custom contracts — not self-serve
