Frequently Asked Questions
What models does Together AI support?
Together AI supports 200+ open-source models including Meta Llama (3.1, 4), Mistral, Qwen, DeepSeek, Mixtral, and proprietary models like Mamba-3. All models are available via serverless inference, dedicated endpoints, or custom fine-tuning.
How much does Together AI inference cost?
Serverless inference pricing ranges $0.03-$1.50 per 1M tokens depending on model. Batch API costs 50% less. Dedicated endpoints start at ~$500/month. GPU cloud pricing from $0.30-$4.25/hour per GPU. Free tier available with API credits.
Can I fine-tune models on Together AI?
Yes. Together AI supports full fine-tuning and LoRA for all available models, including models up to 100B+ parameters. Fine-tuning uses latest techniques (SFT, DPO) with pricing starting at $0.10/1M training tokens and throughput 6x higher than competitors.
Is Together AI SOC 2 and HIPAA compliant?
Yes. Together AI is SOC 2 Type II certified and HIPAA-compliant, with dedicated endpoints and monthly reserved capacity options for enterprises requiring compliance.
Can I use Together AI with LangChain or LlamaIndex?
Yes. Together AI integrates with LangChain, LlamaIndex, Vercel AI SDK, and 20+ frameworks via OpenAI-compatible API or native SDKs. See docs.together.ai/docs/integrations for setup guides.
What is Together AI's moat vs. competitors like OpenAI or AWS Bedrock?
Together AI's moat is research-optimized inference (FlashAttention, Medusa, speculative decoding) delivering 2x speed and 60% cost savings; vendor independence (all open models, you own fine-tune outputs); and custom GPU infrastructure. Trade-off: requires technical expertise vs. managed experiences.
Does Together AI offer a free tier?
Yes. Together AI offers a free tier with API credits for evaluation. No credit card required to start. Pricing scales as usage grows via pay-per-token serverless model.
