AI API pricing has dropped 85% since GPT-4 launched in 2023. Frontier model input now costs under $3/1M tokens. But prices vary wildly between providers, and the cheapest model isn’t always the cheapest for your use case.
Here’s every major provider’s pricing in one place.
Frontier models
🆕 June 10, 2026: Claude Fable 5 launched — Anthropic’s most powerful model ever at $10/$50 per million tokens. It’s a new premium tier above Opus, scoring 95% on SWE-bench Verified. See our full pricing analysis.

Cost per common task
What does a typical developer task actually cost?
| Task | Tokens (approx) | GPT-5.4 | GPT-5.4 Mini | DeepSeek | Local |
|---|---|---|---|---|---|
| Code review (1 file) | 3K in / 1K out | $0.02 | $0.007 | $0.001 | $0 |
| Bug fix | 5K in / 2K out | $0.04 | $0.01 | $0.002 | $0 |
| Full feature | 10K in / 5K out | $0.10 | $0.03 | $0.005 | $0 |
| Codebase analysis | 50K in / 5K out | $0.20 | $0.06 | $0.01 | $0 |
| 8-hour coding session | 500K in / 100K out | $2.75 | $0.83 | $0.10 | $0 |
Monthly cost estimates
| Usage level | GPT-5.4 | GPT-5.4 Mini | DeepSeek | Local |
|---|---|---|---|---|
| Light (10 tasks/day) | $6-12 | $2-4 | $0.30-0.60 | $0 |
| Medium (50 tasks/day) | $30-60 | $10-20 | $1.50-3 | $0 |
| Heavy (200 tasks/day) | $120-240 | $40-80 | $6-12 | $0 |
The smart approach: model routing
Don’t use one model for everything. Route by task complexity:
async def route(message, complexity):
if complexity == "simple":
return await call("deepseek-chat", message) # $0.001
elif complexity == "medium":
return await call("gpt-5.4-mini", message) # $0.01
else:
return await call("claude-sonnet-4", message) # $0.04This gives you frontier quality when you need it and near-zero cost when you don’t. See our model routing guide for implementation details.

Price trends
Input token costs have dropped ~85% since 2023. The trend continues as competition intensifies between OpenAI, Anthropic, Google, and Chinese providers. Expect another 30-50% drop by end of 2026.
The biggest driver: open-source models (GLM-5.1, Qwen 3.6, Llama 4) matching proprietary quality at zero cost, forcing paid providers to lower prices.
