Claude Haiku 5.5 launches at a tenth of Haiku 4.5's price
Anthropic released Claude Haiku 5.5 at $0.10 / $0.50 per million tokens for prompts up to 100K tokens and $0.50 / $2.50 above, with a 1M-token context. Anthropic's launch table puts it ahead of GPT-6 Luna on every benchmark both were run on. Its tokenizer is the Claude 4.7+ one, which turns the same text into about 30% more tokens than Haiku 4.5's.
Every price re-checked against the providers — and retired models marked
All 44 models were checked against each provider's own pricing and deprecation pages. Twelve current models were added, thirteen retired ones are now labelled with the date they were shut down and what replaced them, and every cost estimate now accounts for tokenizer differences — Anthropic documents that Claude 4.7 and later produce about 30% more tokens for the same text.

GPT-6.1 Sol replaces GPT-6 Sol at the same price
OpenAI lists GPT-6.1 Sol at $2 / $10 per million tokens — the same as GPT-6 Sol a week earlier — with cached input halved to $0.10. Prompts over 272K tokens cost $4 / $15.
Anthropic released Claude Sonnet 5.5 at $2 / $10 per million tokens, unchanged from Sonnet 5, with a 1M-token context. Like every Claude since 4.7, its tokenizer turns the same text into about 30% more tokens than earlier Claude — worth counting against GPT-6.1 Sol at the same list price.
Anthropic's new Opus lists at $4 / $20 per million tokens, down from $5 / $25. Cache reads cost $0.20 per million (5% of the input price), and fast mode is $8 / $40.
OpenAI added GPT-6 Sol at $2 / $10 and GPT-6 Luna at $0.10 / $0.50 per million tokens, both with a 1.05M-token context. Luna lists at half the price of GPT-5.6 Luna.
DeepSeek's deepseek-flash endpoint now serves V4.1 Flash at $0.30 / $1.20 per million tokens in peak hours and half that off-peak, with a 1M-token context.
$10 / $50 per million tokens for prompts up to 272K tokens and $20 / $75 above, with a 1.05M-token context — about twice GPT-5.6 Sol's regular $5 / $30.
Google lists Gemini 3.8 Flash at $0.75 / $3.75 per million tokens until 31 December 2026, rising to $1.50 / $7.50 from 1 January 2027. 1M-token context.
The deepseek-chat and deepseek-reasoner names, which served DeepSeek V3.2, stopped accepting requests. DeepSeek's API now lists only V4 Pro and the Flash line.
Anthropic launched Claude Sonnet 5 at an introductory $2 / $10 per million tokens, then made it the standard price and cancelled a planned rise to $3 / $15.
Current models ranked in six categories — value, speed, coding, reasoning, creative and vision — on iOPTERA's editorial scores, with links to each model's page.
