Optimize claude-haiku cost with Claude Code

Haiku is cheap per token, but not zero. Context accumulation applies regardless of model tier. At high session volume, the bill surprises developers who chose Haiku specifically to reduce costs.

What claude-haiku costs per session

Claude Haiku pricing (as of April 2026) is $0.80 per million input tokens, less than Sonnet, far less than Opus. But the accumulation mechanic is identical. A 30-turn session re-sends the growing context on every turn. By turn 30, the average session carries 1.5 million input tokens total.

Why haiku bills still compound

Context accumulation is an API architecture constraint, not a pricing tier behavior. Every Claude model re-sends the full conversation on each new request, Haiku included. Choosing Haiku reduces cost per token, but it does not change how tokens accumulate within a session.

Developers who switch to Haiku expecting dramatically lower bills are often disappointed because they expected the model tier to solve the accumulation problem. It does not. The $192/month figure assumes standard usage. Higher session frequency or longer sessions push that higher.

How The Distillery reduces claude-haiku spend

The Distillery reduces tokens at the source by distilling what goes into the context before the request leaves your machine. This applies equally to all models. Real-world cost reduction is 30-60% depending on session patterns — on Haiku sessions, the absolute dollar savings are lower than on Opus, but the percentage reduction follows the same range: 20% conservative benchmark floor on standard sessions, higher on heavy agentic sessions.

If you switched to Haiku to cut costs, adding context distillation is the logical next step. The proxy handles it automatically with no workflow changes required.
