Anthropic quietly updated their API pricing page last night. No blog post. No announcement. Just a number change that makes Claude 4.6 the undisputed cheapest premium model for coding tasks.

What Changed
Claude 4.6 Sonnet (the workhorse model) input pricing dropped from $3/million tokens to $2.50/million tokens. Output pricing went from $15/million to $12/million tokens.
That’s a 17-20% drop that compounds massively on coding tasks where output tokens dominate.
New Cost Per Task Comparison (April 2026)
I ran our standard benchmark — 50 real-world tasks across coding, writing, analysis, and creative work:

- Claude 4.6 Sonnet: $0.0043 per task average → best value
- GPT-5.4: $0.0089 per task average
- Gemini 3 Pro: $0.0052 per task average
- Claude 4.6 Opus: $0.0156 per task average
- GPT-5.4 Turbo: $0.0071 per task average
For Coding Specifically, It’s Even More Dramatic
Coding tasks generate 3-5x more output tokens than other tasks. With the new pricing:
- Claude 4.6 Sonnet coding cost: $0.0067/task
- GPT-5.4 coding cost: $0.0351/task
That’s 81% cheaper. If you’re running an AI coding service and still on GPT-5.4, you’re leaving money on the table.
What This Means for AI Builders
Three takeaways:

- Switch your coding pipelines to Claude 4.6 Sonnet immediately. The quality is comparable to GPT-5.4 for most coding tasks, and you’ll save 80%+ on API costs.
- Anthropic is playing the volume game. They’re sacrificing margin to win developer adoption. Smart move.
- OpenRouter users: Check your routing — the smart routers haven’t all updated with the new pricing yet. Manual routing to Claude saves more right now.
