DeepSeek Coder V3 from DeepSeek is a budget model priced at US$0.27 per 1M input tokens and US$1.10 per 1M output tokens. For a typical solo-developer workload (8 hours/day, 22 days/month — 1 medium feature, 5 small bug fixes, 4 PR reviews, 2 stack-trace debugs, ~1500 lines of TypeScript, 1 large-doc read, with prompt caching at the default mix) DeepSeek Coder V3 costs about US$5/month. The 128K-token context window covers single-file workloads comfortably.

Running the realistic solo-developer day (1 medium feature + 5 small bug fixes + 4 PR reviews + 2 debug sessions + ~1500 lines of TypeScript + 1 large-doc read, 22 working days) on DeepSeek Coder V3 costs about US$5/month. Heavier workloads scale proportionally; lighter workloads cost less.
128K tokens total, with up to 8K of output. That fits a few dozen source files in a single call.
Providers charge US$1.10 per 1M output tokens against US$0.27 per 1M input — output requires real compute, input comes mostly from cache. Coding agents read many files (input-heavy) and emit compact diffs (low output), so total spend is usually input-driven.
Cache reads typically cost only 10% of the regular input rate. On a coding-agent mix with 50% cache hits, that saves roughly 45% on input — which is about 38% off your total bill on input-heavy workloads. Anthropic models charge a one-time cache-write surcharge (25% over input) that pays for itself after 2–3 hits.
