DeepSeek Search and Fetch: $0.75 per 1,000 successful requests, empty results free. Claude Code and Codex searches are billed from Oct 31, 2026, 16:00 UTC.
Point Claude Code at Z.ai's Coding Plan endpoint and put glm-5.3-flash[1m] in the Opus slot, which runs the main session. Effort defaults to high, not max.
There are no Qwen Image 3.0 weights to download. ComfyUI runs it through two paid Partner Nodes: $0.0429 per standard image, Pro $0.0572 or $0.10725 by size.
In CC Switch Routing mode, Codex gets an empty model list and shows its bundled one, which has GPT-6.1 Terra only from 0.165.0. Go back to Direct and restart.
Google announced Gemini 4 Carbon on October 28, 2026, but only Fairwind cyber defenders can use it. No public API or app date yet; build on Argon meanwhile.
Gemini 4 Carbon edges Claude Opus 5.5 on AA's index, 59.4 to 58.4, but Opus still leads coding agents and office work, and it is the one you can call today.
Gemini 3.6 Flash and later, including Gemini 4 Argon, reject any request whose last turn is model (assistant). End contents on a user turn to fix the 400.
GPT Image 2 costs about $0.005 to $0.43 per image in output on OpenAI's API, set by size and quality. Batch halves it, and ChatGPT has no per-image price.
As of October 29, 2026, $0.03 per image on LaoZhang API is the lowest price found for native 4K GPT Image 2 and 2.5, at every quality tier, edits included.
Nano Banana Pro gives 4K only when you ask for it: 16:9 is 5504x3072. Google charges $0.24 per 4K image, $0.12 on Batch; LaoZhang API $0.09 at any size.
Nano Banana Pro is $0.134 per 1K/2K image and $0.24 at 4K on Google's API; Google AI Pro is $19.99 a month with no API. LaoZhang API: $0.09 a call at any size.
Claude Haiku 5.5 and GPT-6 Luna share $0.10/$0.50 rates under 100K tokens, yet Haiku cost 2.2x more per task at default effort and reprices 5x above 100K.
Claude Haiku 5.5 costs 1/20 of Sonnet 5.5 per input and output token but trails it on agentic coding. Move checkable work to Haiku; keep agents on Sonnet.
GPT-6.1 Terra's 1/9 cost claim is max vs max. At equal AA scores, Opus 5.5 high costs 3.6x Terra max per task, and English input bills about 5.8x.
Against GPT-6.1 Sol, Opus 5.5 costs exactly 2x per token under 272K input and stays pricier above. Opus scores higher; pay only where it passes more tasks.
Sonnet 5.5 keeps Sonnet 5's $2/$10 token prices. In Artificial Analysis's October 5 tests it cost less per task from low to xhigh and about 51% more at max.
Same $2/$10 list price, but Sonnet 5.5 costs 2.2–7.9x GPT-6.1 Sol per AA task. Start on Sol; use Sonnet for terminal agents and prompts over 272K tokens.
GPT-6 Astra outscores Sonnet 5.5 at every effort level on Artificial Analysis' index. Sonnet is cheaper per task up to high, faster, and wins above 272K input.
Sonnet 5.5 costs half as much per token and suits well-scoped work at low or medium effort. At max it costs as much per task as Opus 5.5 and scores lower.
Gemini 4 Argon: resend with continuationToken on CONTINUATION, raise the budget when MAX_TOKENS has no text. OpenAI-compatible endpoints can't continue.
Gemini 4 Argon opened to paid API users on October 13 at $2/$10, doubling December 1. At matched effort it costs more per task than Opus 5.5 and 6.5x GPT-6.1 Sol.
Gemini 4 Argon lists at 2.67x 3.8 Flash per token, but on five same-prompt calls it cost 1.57x as much through Nov 30, 2026, and 3.15x in December.
As of October 14, 2026, you can call GPT-6.1 Sol and Gemini 4 Argon, available since October 13. Fable 5.5 is unannounced, and GPT-6.1 Astra was shelved.
Both list at $10/$50 per million tokens, but on October 26, 2026 Fable 5.1 counted 1.45x Astra's tokens for English and cost 1.5–1.6x on tasks both passed.
