What happened
Anthropic released Claude Haiku 5.5, its first Haiku-tier update in about a year, live on the Claude Platform and in Claude Code, with a 43 score on the Artificial Analysis Intelligence Index (up 26 points from the last Haiku). It is priced to match OpenAI’s GPT-6 Luna: $0.10 input / $0.50 output per 1M tokens under 100K prompt tokens, $0.50 / $2.50 over 100K, and cache reads at $0.01 / $0.05 per 1M; Anthropic says it costs about 75% less to run than Haiku 4.5 on average. The same day, Sonnet 5.5 cache reads were halved from $0.20 to $0.10 per 1M, monthly Claude Platform API credits were added for Max 5x ($100), Max 20x ($200), and Team (up to $500 pooled), and computer-use/browser-use toolsets were built into the Python and TypeScript Claude SDKs.
Why it matters
If you route high-volume summaries, compactions, or database queries to a small model, recalculate cost per task: Haiku 5.5 is positioned as a subagent for high-volume work, but prompts over 100K tokens cost 5x more per token, so chunking/compaction can matter more than the headline price. Sonnet 5.5 cache reads at $0.10/1M and pooled Team API credits up to $500/month can change long-running agent economics and third-party harness spend. No Malaysia- or SEA-specific impact is stated in the text.
Discussion angle
Should you split work into Opus/Sonnet 5.5 for heavy thinking and Haiku 5.5 for high-volume subagent tasks, or use Sonnet 5.5's halved cache reads for long-context agent loops? Run a cost-per-task comparison at under-100K vs over-100K prompts before changing model routing.
