Claude 4.5 Haiku — the budget workhorse
Haiku is the go-to for high-volume, cost-sensitive workloads. Here’s what each provider charges per million tokens:
| Provider | Input/1M | Output/1M | vs Anthropic |
|---|---|---|---|
| KIE AI | $0.35 | $1.75 | 65% cheaper |
| Anthropic (direct) | $1.00 | $5.00 | baseline |
| OpenRouter | $1.00 | $5.00 | same |
| Replicate | $1.00 | $5.00 | same |
| AIMLAPI | $1.30 | $6.50 | 30% more |
KIE AI stands out here — at $0.35/$1.75, it’s nearly a third of what you’d pay going direct to Anthropic. For Haiku workloads processing millions of tokens daily, that adds up fast.
Claude 4.6 Sonnet — the sweet spot
Sonnet balances capability and cost. It’s the model most teams use in production.
| Provider | Input/1M | Output/1M | vs Anthropic |
|---|---|---|---|
| KIE AI | $1.05 | $5.25 | 65% cheaper |
| Muapi | $1.80 | $9.00 | 40% cheaper |
| Anthropic (direct) | $3.00 | $15.00 | baseline |
| OpenRouter | $3.00 | $15.00 | same |
| Replicate | $3.00 | $15.00 | same |
| WaveSpeed AI | $3.00 | $15.00 | same |
| AIMLAPI | $3.90 | $19.50 | 30% more |
Again, KIE AI leads at 65% below Anthropic’s price. Muapi is also worth considering at 40% savings.
Claude 4.6 Opus — the flagship
Opus is the most capable and most expensive Claude model. Savings matter even more here.
| Provider | Input/1M | Output/1M | vs Anthropic |
|---|---|---|---|
| KIE AI | $1.75 | $8.75 | 65% cheaper |
| Muapi | $3.00 | $15.00 | 40% cheaper |
| Anthropic (direct) | $5.00 | $25.00 | baseline |
| OpenRouter | $5.00 | $25.00 | same |
| Replicate | $5.00 | $25.00 | same |
| AIMLAPI | $6.50 | $32.50 | 30% more |
| WaveSpeed AI | $15.00 | $75.00 | 200% more |
At $1.75/$8.75, KIE AI makes Opus accessible for use cases where you’d normally default to Sonnet for budget reasons.
How are third-party providers cheaper?
Providers like KIE AI and Muapi can offer lower prices through:
- Volume agreements with Anthropic for bulk token purchases
- Infrastructure optimization reducing per-request overhead
- Competitive pricing to attract developers from direct API access
The tradeoff is usually around rate limits, SLAs, and feature support. Anthropic’s direct API gives you the highest rate limits and earliest access to new features.
Which provider should you pick?
- Lowest cost, all models: KIE AI (65% savings across the board)
- Good savings, established provider: Muapi (40% savings on Sonnet/Opus)
- Maximum reliability: Anthropic direct (official SLAs, highest rate limits)
- Routing flexibility: OpenRouter (fall back to other providers automatically)
Bottom line
You can cut your Claude API bill by up to 65% just by switching providers. For a team spending $1,000/month on Claude Sonnet through Anthropic, that’s $650/month saved with KIE AI — same model, same outputs.
