Use Case Recommendations
Best for: LLM Gateway
LLM Gateway is an open-source, OpenAI-compatible routing layer that puts one API in front of more than 200 models across 40-plus providers, including OpenAI, Anthropic and Google. The problem it solves is operational rather than intellectual: teams that use several providers end up juggling separate keys, separate dashboards, separate billing and separate SDK quirks, and switching provider for a given model means a code change. Pointing an existing OpenAI-compatible client at the gateway collapses that into one endpoint with real-time cost tracking across all of it. Around the core routing sit the features that make a gateway worth running in production — automatic provider selection and custom routing rules, budgets and spend controls, prompt caching, guardrails, reliability failover, and activity logs with exportable data. The commercial model is unusual and worth reading carefully: the free tier is free forever with all 200+ models available and bring-your-own-keys included, and the platform fee is 5% on credit usage rather than a monthly subscription, so cost scales with spend rather than seats. Metadata retention is free while full payload storage is billed at $0.01 per million tokens. Supporting surfaces include an MCP server, an AI SDK provider, a token cost calculator, model comparison and rankings pages, and the vendor states it is SOC 2 Type II certified.
Ideal use cases:
- •Teams or individuals who need one openai-compatible endpoint for 200+ models across 40+ providers
- •Teams or individuals who need real-time cost tracking and spend controls across every provider
- •Teams or individuals who need automatic provider routing plus custom routing rules
- •Teams or individuals who need prompt caching, guardrails and reliability failover
- •Anyone focused on llm-gateway workflows
- •Anyone focused on api workflows
Best for: Together AI
Together AI is a leading cloud platform for running open-source LLMs with fast inference, fine-tuning, and custom model deployment. It offers the widest selection of open models (100+ including Llama, Mistral, FLUX, SDXL) with serverless or dedicated endpoints. Together is popular with enterprises needing the power of frontier-style models with data privacy — no model trains on your data. Fine-tuning from $0.80/million tokens makes custom models accessible.
Ideal use cases:
- •Teams or individuals who need 100+ open-source models (llama 3, mistral, qwen, flux)
- •Teams or individuals who need serverless and dedicated inference endpoints
- •Teams or individuals who need fine-tuning api (supervised, lora)
- •Teams or individuals who need image generation (flux.1, sdxl)
- •Anyone focused on together ai workflows
- •Anyone focused on llm inference workflows
