Steven · 2026-08-20
Four new vendors, plus a round of updates to models already on the site. 117 models across 23 vendors now.
FEATAdded LongCat, with LongCat-2.0. $0.3 input / $1.2 output per million tokens, a limited-time platform discount off the $0.75/$2.95 list rate.
FEATAdded StepFun, with step-3.7-flash at $0.2 input / $1.15 output.
FEATAdded Writer, with three Palmyra models: palmyra-x6 ($2/$8, frontier), palmyra-x5 ($0.6/$6), and palmyra-x4 ($2.5/$10).
FEATAdded Xiaomi, with mimo-v2.5-pro ($0.435/$0.87) and mimo-v2.5 ($0.14/$0.28).
FEATByteDance added doubao-seed-2.1-turbo ($0.42/$2.1) and doubao-seed-evolving ($0.84/$4.2), a continuously-updated production alias currently pointing at the 1M-context version announced July 14.
FEATCohere added two free models, command-a-plus-05-2026 and north-mini-code-1-0.
FEATMiniMax added MiniMax-M3, tagged frontier. $0.3/$1.2, stepping up to $0.6/$2.4 once a request crosses 512K input tokens.
FEATOpenAI added gpt-5.5 ($5/$30) and gpt-5.5-pro ($30/$180) from April, plus gpt-5.4-pro ($30/$180) and the older gpt-5-pro ($15/$120, deprecated, Responses API only). gpt-5.5, gpt-5.5-pro, and gpt-5.4-pro all step up to a higher rate once a request crosses 272K input tokens, and the two Pro models don't offer a cached-input discount.
FEATCached-input pricing filled in for gpt-5, gpt-5-mini, and both gpt-4.1 snapshots, previously missing.
FIXgpt-5.6-sol, gpt-5.6-terra, and gpt-5.6-luna were listed with a vague "1M+" context window. That's now the real number, 1.05M, matching the rest of the GPT-5.x lineup.
