the price war just went ten times lower. anthropic's haiku 5.5, out oct 8, charges 10 cents per million input tokens and 50 cents for output, a tenth of the old rate and under deepseek's flash pricing.
the cheap tier is now the battleground.
Context
Anthropic's Claude Haiku 5.5 pricing is 0.10 dollars per million input tokens and 0.50 dollars per million output tokens for prompts up to 100,000 tokens, and 0.50 and 2.50 dollars above that, per Anthropic's pricing page. Haiku 4.5 is listed at 1 and 5 dollars, so the short-prompt rate is a tenth.
Anthropic's launch page is dated Oct 7, 2026.
The 0.10 and 0.50 dollar prices and the tenth of the old rate match Anthropic's pricing, for prompts up to 100,000 tokens only. Anthropic's launch page is dated Oct 7, not Oct 8. An aggregator, explainx, lists DeepSeek Flash Latest at 0.00 input and 0.60 output per million tokens, so 'under DeepSeek's flash pricing' holds on output only by that listing.
'the cheap tier is now the battleground' is the author's opinion.
