claude-3-5-haikuAnthropic Claude 3.5 Haiku: Complete 2026 Pricing, Prompt Cache & Context-Mode Audit
Anthropic Claude 3.5 Haiku is benchmarked at $0.80 (per 1M input tokens), $4.00 output, and $0.08 warm cached read (90% explicit cache read ($0.08/1M), 1.25x ($1.00/1M) cold write fee). Across 24-hour rolling W1–W4 telemetry probes, Anthropic Claude 3.5 Haiku delivers a 285 ms P90 TTFT and 132 tok/s median throughput over a 200,000 tokens capacity.
1. Anthropic Claude 3.5 Haiku Official Rate Card, Context-Cliff Threshold & Tokenizer Audit
Engineering teams evaluating Anthropic Claude 3.5 Haiku must account for both nominal per-million token rates and underlying tokenizer density (claude-v3-bpe: 1.06x). When context history crosses the cliff boundary (200K context window cap), unpruned tool logs trigger steep billing multipliers.
| Billing Dimension | Verified Rate (USD) | FinOps Guardrail & Settlement Rule |
|---|---|---|
| Uncached Standard Input | $0.80 / 1M | Keep uncached dynamic suffix below 15% of total prompt payload |
| Warm Prefix Cache Read | $0.08 / 1M | 90% explicit cache read ($0.08/1M), 1.25x ($1.00/1M) cold write fee |
| Cold Cache Creation / Write | $1 / 1M | Strip volatile timestamps from system prompt to prevent 1.25x cold rebuilds |
| Standard Streaming Output | $4.00 / 1M | Enforce pre-authorized token hold & atomic release on client SSE disconnect |
| 24h Asynchronous Batch API | $0.4 In / $2 Out | 50% flat discount for non-interactive evaluation & dataset indexing pipelines |
2. Anthropic Claude 3.5 Haiku in Coding Agents: Raw Tool Output vs. Context-Mode Sandbox vs. Etuki Cache Router
In Claude Code, Cursor, Codex, and Gemini CLI, every raw MCP tool call dumps massive payloads into your context window (a Playwright snapshot = 56 KB; 20 GitHub issues = 59 KB; 47 × Read() = 700 KB). While open-source Context-Mode folds 315 KB → 5.4 KB (or 700 KB → 3.6 KB via ctx_execute subprocess sandboxing and SQLite FTS5 BM25 search), naive context rewriting can inadvertently invalidate Anthropic/OpenAI prefix cache breakpoints, turning 0.1x warm reads into 1.25x cold writes! Pairing Context-Mode with Etuki 4-Block Prefix Cache Pinning locks your static prefix while folding dynamic tool stdout:
