DeepSeek R1 from DeepSeek is a budget model priced at US$0.55 per 1M input tokens and US$2.19 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 R1 costs about US$12/month. The 128K-token context window covers single-file workloads comfortably.

Typical mix: coding-agent (85% input, 50% cache hits). Values show the maximum count of each task type at that budget.
Coding
Trained or post-trained for code generation tasks.
Reasoning
Strong multi-step reasoning over complex prompts.
Multimodal
Not supported
Prompt cache
Cache reads billed at ~10% of input price — cuts agent costs sharply.
Batch API
Not supported
Tool use
Native function-calling / tool-use API support.
Long context
Not supported
Extended thinking
Hidden reasoning tokens (Anthropic 'thinking' / OpenAI reasoning).

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 R1 costs about US$12/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$2.19 per 1M output tokens against US$0.55 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.
Extended-thinking / reasoning tokens are billed at the full output rate but never appear in your visible response. On hard agentic tasks they can double your output bill, lifting the monthly total by 20–30%. Enable thinking only when the standard response visibly fails.
