Overall Score
Based on our independent scoring across 6 dimensions, Anthropic API scores 83/100 overall versus Together AI's 76/100 — a 7-point margin. Anthropic API leads on Output Quality in particular. That said, Together AI may still be the right choice if the dimensions where it scores higher match your specific priorities — the radar chart above shows the full profile side by side.
Both Anthropic API and Together AI offer a free tier, so entry-level cost is not a differentiating factor. Compare the feature and usage limits of each free plan to see which gives you more headroom before a paid upgrade is needed.
Anthropic API scores higher on Multimodal — 80/100 versus 55/100 for Together AI. If multimodal is your primary decision criterion, Anthropic API is the stronger choice in this head-to-head.
Switching between ai apis tools is generally possible but involves migration effort: exporting your data or configuration from Anthropic API, re-importing or reconfiguring in Together AI, and updating any API integrations or environment variables in your codebase. The effort scales with how deeply embedded the tool is in your stack. Test Together AI on a non-production project first before migrating.
Anthropic API (83/100) is the better fit for teams who prioritise output quality — its strongest dimension — and who want a free entry point. Together AI (76/100) is the better fit for teams who prioritise price / value and want a free entry point. If both dimensions matter equally, the overall score winner (Anthropic API) is the safer default choice.
