Top Recommended Alternatives
Portkey
LLM Gateway & Observability
From
FreeProduction AI control plane: AI gateway, prompt management, observability, guardrails, and MCP gateway in front of 1,600+ LLM providers.
Key Strengths:
- ✓OpenAI-compatible API gives teams one integration point while still routing to 1,600+ models across providers such as OpenAI, Anthropic, Google, Mistral, AWS Bedrock, Azure OpenAI, Cohere, Together, Fireworks, and Groq.
- ✓Fallback and load-balancing are built into the gateway layer, so reliability policies can be configured centrally instead of duplicated across each application service.
Cloudflare AI Gateway
Deployment & Hosting
From
FreeCloudflare AI Gateway is a free AI observability and control layer that proxies requests to OpenAI, Anthropic, Google, and 25+ providers with caching, rate limiting, logging, DLP, and Guardrails.
Key Strengths:
- ✓Core features are genuinely free on every Cloudflare account — analytics, caching, rate limiting, DLP, persistent logs
- ✓One line of code change works with existing OpenAI, Anthropic, and Google SDKs across 25+ providers
Together AI
AI Model Hosting & Inference
From
$0.02/1M tokensAI-native cloud for inference, fine-tuning, and dedicated GPU clusters, offering 200+ open-source and frontier-class models behind an OpenAI-compatible API plus reserved H100/H200/B200 capacity.
Key Strengths:
- ✓Breadth of open-weight model catalog (200+) with one OpenAI-compatible API
- ✓One account spans serverless, dedicated endpoints, fine-tuning, and reserved GPU capacity
Fireworks AI
AI Model Hosting & Inference
Production inference platform for open-weight LLMs, multimodal models, and custom fine-tunes — known for very fast serving (FireAttention/FireOptimizer), reliable function calling, and JSON mode at low per-token prices.
Key Strengths:
- ✓Reliable function calling, JSON mode, and parallel tool calls across the open-model catalog — table stakes for production agents
- ✓FireFunction-V2 is purpose-built for tool-calling accuracy, materially beating generic Llama tool-use in agentic loops
Groq
AI Model Hosting & Inference
AI inference cloud built on Groq's own LPU (Language Processing Unit) chips that serves open-weight LLMs, Whisper, and vision models at the lowest latency in the market, with an OpenAI-compatible API.
Key Strengths:
- ✓Custom LPU silicon delivers tokens-per-second that is typically 5–10x faster than GPU baselines on open LLMs
- ✓OpenAI-compatible API plus a generous free developer tier make adoption a base-URL change away
