## Summary

Anthropic released **Claude Haiku 5.5** on October 6, 2026, positioning it as a cheaper, faster alternative to OpenAI’s **GPT-6 Luna** at the same price. The model supports **1M-token context** (up from 200K) and includes **effort controls** and **adaptive thinking**, but uses **~3x more tokens** than Luna at max effort, offsetting some cost savings. Anthropic also cut **Sonnet 5.5 cache-read costs by 50%** and expanded **API credits** for subscribers, all aimed at agentic workflows like **Claude Code, Devin, and Copilot**.

Independent benchmarks from **Artificial Analysis** show Haiku 5.5 scoring **43 on the Intelligence Index** (up 26 points from Haiku 4.5), slightly ahead of **Gemini 3.8 Flash (41)** and **GPT-6 Luna (38)**. It trails **Sonnet 5.5 (56)** but outperforms competitors like **GLM-5.3 Flash (42)** and **Kimi K3 (44)**. However, **token efficiency remains a concern**: Haiku 5.5 uses **~162K tokens** per task at max effort, compared to Luna’s **~50K**. Partners like **Cursor, GitHub Copilot, and Devin** report cost savings and performance gains, though **automation benchmarks are depressed** by a pre-release safety bug. Anthropic has not yet published full cost-per-task figures for the new tiered pricing.

## Key points

- Anthropic priced Haiku 5.5 to match OpenAI’s GPT-6 Luna at $0.10/$0.50 per 1M tokens (under 100K tokens)
- Haiku 5.5 scores 43 on Intelligence Index, ahead of Luna (38) but behind Sonnet 5.5 (56) and Kimi K3 (44)
- Token usage is 3x higher than Luna at max effort, offsetting cost savings; partners report mixed but positive results

## Why it matters

Haiku 5.5’s pricing and performance push Anthropic into direct competition with OpenAI’s Luna, targeting cost-sensitive agentic workflows. Its **1M-token context** and **effort controls** could reshape how developers build subagents, but **token inefficiency** may limit real-world adoption.
