Pricing models providers use for LLM API access, including per-token rates, cached-input discounts, and peak/off-peak fee schedules.
OpenAI will retire GPT-4o, GPT-4.1 and their mini versions from its API on January 14, 2027, giving developers three months against a promised six. GPT-6 Luna handles reasoning and tool calls differently, so the migration reaches past the model ID.
Reality
Google prices Gemini 4 Argon at $2 input and $10 output per 1M tokens through Nov 30, then $4 and $20. Budgets built on the launch rates fall short by half from December 1, on figures a dev.to guide takes from Google's pricing page.
Reality
Until November 30, Google's Gemini 4 Argon bills input at $2 per million tokens and output at $10 per million, then $4 and $20. Thinking tokens bill at the output rate, according to a dev.to walkthrough of Google's pricing page.
Reality
Google said Gemini 4 Argon's API price doubles by the end of November 2026, from $2 to $4 per million input tokens, dev.to reports. A pilot budgeted at the launch rate understates the later bill by half.
Reality
OpenAI, Microsoft and Perplexity launched decision-model APIs within nine days at $0.10, $0.042 and $0.02 per million input tokens. Perplexity's 27B weights are Apache 2.0, so a buyer with a roughly 49 GiB GPU can self-host v1.1.
Reality
Anthropic's Claude Haiku 5.5 costs $0.10/$0.50 per million tokens up to 100,000 input tokens, then $0.50/$2.50 on the whole request. A dev.to breakdown advises sending Haiku only narrow, verifiable subagent work and keeping Sonnet 5.5 as the default coder.
Reality
Anthropic gave Max 5x subscribers $100 a month in API credits from 7 October, Max 20x $200 and Team plans up to $500 pooled. The credit excludes interactive Claude Code and expires each cycle, so the model a team runs sets what it buys.
Reality
Artificial Analysis measured the score itself, and the weights are on Hugging Face under MIT, but MiMo-V2.6-Pro holds 1.02 trillion parameters, so most teams will reach it through an API at $0.43 per million input tokens.
Reality
Google's new workhorse Flash is a model-string swap for anyone on AI Gateway, discounted through 31 December 2026. The claim worth testing is reduced tool-calling loop failures, not benchmark deltas.

Google DeepMind's Gemini 4 Argon, priced at half of Claude Opus 5.5, goes first to vetted cyber defenders, and paid API customers have no date. Until Google sets one, teams can only check its benchmark claims on paper.
Reality
DeepSeek V4.1 Flash costs $2.10 off-peak for an agent run that costs $75 on Claude Opus 5, about 36x less, according to a dev.to analysis. Paying peak-hour rates halves that gap to about 18x, and running at max effort cuts it to about 15x.
Reality
Anthropic cut the Claude Sonnet 5.5 cache-read rate from $0.20 to $0.10 per million tokens on October 7. A team saves $0.10 for each million cache-read tokens it logs, so its total bill drops by half the share those reads already held.
Reality
Google announced Gemini 4 Argon, its first Gemini 4 model, with early access limited to internal teams and vetted cyber defenders in its Fairwind program. The published API price doubles once an introductory window closes. Teams cannot yet test the coding and long-output claims they would budget around, because there is no public access.
Reality
OpenAI's GPT-6.1 Sol matched GPT-6 Astra on all 15 runs of a New Stack test, costing $2.66 against Astra's $14.77. Both models scored perfectly, so the run confirms the price gap on real token counts while leaving the accuracy ceiling untested.
Reality
Anthropic prices Claude Sonnet 5.5 at half Opus 5.5's per-token rate, but Artificial Analysis measured $7.67 per task at max effort against Opus's $5.98. In The New Stack's own tests, runs that were billed but never finished decided which model cost less per completed job.
Reality
Anthropic now includes monthly Claude API credits in Max and Team plans, with Team seats pooled into one balance capped at $500. Whichever Console organization an owner links decides whether that money pays for new internal agents or offsets an API bill the company already pays.
Reality
OpenAI's Decisions API answers yes/no, pick-one and scale questions for $0.10 per million input tokens, with output free. Jev sells the same three question types for text at less than half that, so OpenAI's case rests on image input and compliance terms.

Google is charging $2 and $10 per million input and output tokens for Gemini 4 Argon at launch, half the $4 and $20 it will charge later. For a model that writes long answers and is open only to vetted cyber defenders, cost per task is the figure to check before switching.
Reality
Habr user donseo's test of 11 tokenizers found Claude Opus 5 turns Russian into 2.96 times the tokens of the same English text. Anthropic bills $5 per million input tokens in either language, so Russian on Opus 5 costs nearly three times as much to send.
Reality
Google will give vetted defenders and its own teams a Gemini 4 Argon build with no cyber guardrails, saying the model finds and patches critical flaws unaided. Wiz is the first named outside user, and the bug-finding evidence published so far comes from Google's own internal tests.
