OpenAI API Alternatives 2026
OpenAI API — the pioneer. $5-15 per 1M tokens. 2026 alternatives: Anthropic Claude API (Claude Opus 4.7 — best for long context + code), Google Gemini API (2M context, cheaper), Together.ai (open source model hosting, Llama 3 70B $0.88/1M), Groq (LPU fastest inference, 500+ tokens/sec), Fireworks AI (serverless, Firefunction tool calling), Replicate (pre-built models).
Below: competitor overview, feature comparison, when to pick each, FAQ.
