OpenAI gives GPT-4o and GPT-4.1 92 days — half the notice the same family got in April
On 14 October 2026 OpenAI deprecated the last GPT-4o, GPT-4o mini, GPT-4.1 and GPT-4.1 mini snapshots with a 14 January 2027 shutdown — 92 days, against the 184 days the gpt-4o-2024-05-13 snapshot got in April and against OpenAI's own published floor of 'at least 6 months' for generally available models. The same day, GPT-5.5 left the ChatGPT, ChatGPT Work and Codex model pickers on every plan, five months after becoming the default. Fine-tuned models follow their base model out.
Read story →Google retired two Gemini Flash models by rerouting them, not by failing them
Google's Gemini API changelog for 8 October 2026 deprecated gemini-3.5-flash and gemini-3.7-flash, and said every request to both is automatically routed to a different model. Both IDs are gone from the models page and the pricing page, and the deprecations page rows that cover them carry no date for when any of it happened. The bill does not change; what changes is that pinning a Gemini model ID no longer pins a model.
Read story →OpenAI's fastest tier reached Europe on 8 October — on every model except the flagship
On 8 October 2026 OpenAI shipped Ultrafast for GPT-6.1 Sol at $12/$60 per million tokens, six times standard, and became the first OpenAI speed tier purchasable under EU data residency. GPT-6 Astra's Ultrafast remains global-and-US-only at $60/$300. For a European buyer that turns latency from a price decision into a model decision: you can buy speed, but only on the model one point below the flagship.
Read story →Claude Haiku 5.5 is a tenth of Haiku 4.5's price — until your prompt passes 100,000 tokens, where it costs five times more
On 7 October 2026 Anthropic launched Claude Haiku 5.5 at $0.10/$0.50 per million tokens and cut Sonnet 5.5's cache read from $0.20 to $0.10. Haiku 5.5 is the first Claude model priced by prompt length: above 100,000 tokens every rate multiplies by five — the steepest long-prompt surcharge any major vendor charges, at the lowest threshold. Because the cliff is measured in Anthropic's newer tokenizer, it arrives at about 77,000 Haiku-4.5-equivalent tokens.
Read story →Mistral's new flagship costs less than its own mid-tier — and the price on the model card is a sale with no published end date
Mistral Large 4 launched 6 October 2026 at a list price of $1.36 input and $4.18 output per million tokens. Mistral Medium 3.5, the mid-tier it sits above, is $1.50 and $7.50. The flagship is cheaper on both ends with four times the context, which retires Medium 3.5 as a purchase. The number the model card actually shows today is half the list — $0.68 and $2.09 — struck through against the higher rate, and Mistral has not published the date the discount ends.
Read story →Claude Sonnet 4.5 has 61 days to live, and the replacement Anthropic names is 13% cheaper — not 33%
On 30 September 2026 Anthropic deprecated claude-sonnet-4-5-20250929 with retirement set for 30 November — 61 days, one day over the 60-day minimum its own policy promises, and the fifth consecutive deprecation to land within two days of that floor. The recommended replacement drops the list price from $3/$15 to $2/$10, but Sonnet 5.5 runs a tokenizer that produces about 30% more tokens for the same text. Net effective saving: about 13%.
Read story →GPT-6.1 Sol and Claude Sonnet 5.5 both cost $2/$10, land a day apart, and bill an order of magnitude differently
OpenAI shipped GPT-6.1 Sol at DevDay on 29 September 2026 at $2 per million input tokens and $10 per million output — the same list price Anthropic set for Claude Sonnet 5.5 the day before. The identical headline hides a 2x gap in cache reads, a 272K-token surcharge cliff on one side and none on the other, and independent per-task costs that differ by more than 10x. The rate card has stopped being the number that decides the bill.
Read story →Claude Sonnet 5.5 costs exactly what Sonnet 5 cost — and breaks five things on the way in, plus a sixth that raises no error
Anthropic shipped Claude Sonnet 5.5 on 28 September 2026 at $2/$10 per million tokens, identical to Sonnet 5, with a one-line model ID swap as the headline migration. The docs list five breaking changes behind that line — disabled thinking, forced tool use, thinking-block binding, the old computer use tool, and advisor pairings — and a sixth that changes the response shape without failing any request. The free upgrade has a migration bill.
Read story →Anthropic stripped filenames out of its enterprise audit log — retroactively, and the lookup that restores them dies with the file
On 24 September 2026 the Claude Compliance API Activity Feed stopped returning filenames, project document names and artifact titles, including on activities recorded before that date. Activities are retained for six years; the names are not. Recovering one now requires a Compliance Access Key with read:compliance_user_data — a strictly higher privilege tier that reads every chat in the tenant — and it returns nothing once the file is deleted, which is the exact moment an investigation needs it.
Read story →Anthropic now bills refusals that return nothing — in the three categories where its own docs say benign work gets caught
On 24 September 2026 Anthropic resumed billing for Claude API refusals that arrive before any output, in three of five categories: bio, frontier_llm and reasoning_extraction. You pay the full input rate for an empty response, the request still consumes rate limit, and when fallback is enabled you now pay for the refused attempt and the retry. Anthropic's own category table says beneficial life sciences work and benign machine learning work can trigger two of the three billed categories, and no false-positive rate has been published.
Read story →OpenAI's oldest API surface runs out of models on Monday — and its own docs disagree about when your legacy fine-tunes die
On 28 September 2026 OpenAI shuts down gpt-3.5-turbo-instruct, davinci-002, babbage-002 and gpt-3.5-turbo-1106. The first three are the only models the legacy /v1/completions endpoint serves, so the endpoint does not get a replacement — it gets zero inhabitants. The deprecation table maps all four onto gpt-5.6-terra, a reasoning model on a different API surface at six times the output price, with no echo, no suffix, no best_of and no raw log-probabilities. And OpenAI's stated rule for fine-tunes contradicts its own shutdown date by 25 days.
Read story →Google gave the AI avatar a face and didn't give it a price — that's the part to plan for
Gemini 3.8 Live with Live Avatar went generally available in Gemini Enterprise on 24 September 2026, adding real-time lip-synced video to Google's speech-to-speech stack across 97 languages with US and EU endpoints. The audio still bills at $3/$12 per million tokens — about $0.011 a conversational minute. The video bills at nothing, because Google has not published a rate for it. HeyGen charges $0.10–$0.20 a minute for the same pixels. An unpriced line item on a GA enterprise product is a forward liability, not a discount.
Read story →Alibaba just dropped speech-to-text through the price floor — and changed the meter on the way down
Qwen-Audio-3.1 landed at the Apsara Conference on 22 September 2026 with five models and cuts of ~70% on TTS, ~85% on Realtime and up to 95% on ASR. Worked against Qwen's own 25-tokens-per-second audio rate, recognition lands near $0.016 per audio-hour — roughly a tenth of the floor Deepgram, AssemblyAI and Meta had held for years. The catch is that the meter moved from audio-seconds to tokens on the same day, two of the five models have no API yet, and the rate card is not on the international pricing page.
Read story →SpaceXAI's X Search meter moves from calls to results on 21 September — and the number you now pay for is one the model picks, not you
From 21 September 2026 at 12:00 PM PT, X Search bills $5 per 1k posts fetched and $10 per 1k user profiles fetched, replacing $5 per 1k calls. Break-even is exactly one post per call, so any real search is a price increase. Parent and quoted posts count too — results pulled in by thread structure rather than by your query — and the published tool parameters include no way to cap how many results come back. The token row on the Grok rate card did not move. The part of the bill you can forecast did.
Read story →Anthropic shipped on-demand compaction on 14 September — and the usage field your cost dashboard reads is no longer the bill
The Messages API can now compact a conversation on request, in the background, keeping recent turns verbatim. Useful. The part nobody put in a headline is in the billing note: usage.input_tokens and usage.output_tokens explicitly exclude the compaction iteration. In Anthropic's own worked example the top-level fields report 23,000 input tokens against 203,000 actually billed. Every FinOps script built on those two fields now undercounts, silently, on exactly the requests that cost the most.
Read story →Sakana priced Fugu Max 60% under the frontier — but the meter counts the agents talking to each other, and that is 5-12x the tokens you see
Sakana AI shipped Fugu Max at $2/$6 and Fugu Ultra v2 at $5/$30 on 11 September, undercutting Sonnet 5 and Opus 5 on output. The catch is in the usage object: Fugu bills orchestration tokens — the internal planning, delegation and verification traffic — at full rates, and independent measurement of Fugu Ultra v1 put that overhead at 5x to 12x the visible output. That moves Fugu Max's effective cost to roughly $24-$61 per million useful output tokens. Also: no EU/EEA availability, and routing is undisclosed by design.
Read story →GPT-Live-1 didn't just cut the price of voice — it changed the meter, and that decides which calls got cheaper
OpenAI shipped full-duplex voice to the API on 10 September at a flat $0.05 per minute, billed per second, replacing token-metered realtime pricing that ran $0.06–$0.11 a minute. Flat wall-clock billing makes dense conversations cheaper and silence expensive — the opposite of what you were optimizing for. And $0.05 is only the mouth: reasoning is a separate backend bill that swings a ten-minute call from $0.60 to $1.40.
Read story →OpenAI re-hosted the agent layer it spent a year un-hosting — and priced the harness at zero, which is the part that spends your money
The Agents API went to public beta on 10 September with no fee of its own: you pay tokens, tools and container hours. But the free harness is the component that decides how many tokens you burn — it owns compaction, recovery and subagent spawning. Meanwhile sandboxes bill by wall-clock, so the 'runs for days' pitch and the meter point in opposite directions. And in beta it is US-only with no zero-data-retention.
Read story →DeepSeek is retiring its flagship by routing it away — and on 14 September anyone still calling V4-Pro gets a reasoning downgrade with the price cut
V4.1-Flash launched 10 September at up to 86% below V4-Pro, with deepseek-v4-pro due to route to it on 14 September. Updated 14 September: DeepSeek reversed the retirement and V4 Pro API service continues with billing unchanged, while the superseded routing notice is still live in its release notes. Flash beats Pro on agent benchmarks and loses on reasoning — so the migration was always a capability trade, not a discount. And the peak-hour windows charge European mornings double while US working hours sit entirely off-peak.
Read story →OpenAI published the first itemized bill for a 10,000-agent swarm — and the $22.5M everyone quoted counts output tokens only
The Navier-Stokes sprint burned 300 billion output tokens across a week and 130 billion on one problem. The widely-reported $22.5M is exactly 300B at $75 per million — Astra's above-272K output rate, with no input, no cache writes. It is a floor, not a bill. But it is also the first agent swarm with published unit counts, which means you can finally price a fleet with arithmetic.
Read story →A federal advisory just told US model providers to serve degraded models to suspected distillers — and to vary it so quality evaluation cannot detect it
Joint advisory AA26-251A names six Chinese AI firms for industrial-scale distillation. The headline is the accusation. The part that changes your procurement is mitigation two: serve degraded responses to suspects, varied across requests to complicate quality evaluations. The published detection signature describes an ordinary 24/7 agent fleet routed through a gateway.
Read story →OpenAI shipped two image models at one price — so the model name is not your cost decision, and the parameter that is swings 35x
GPT Image 2.5 arrived on 8 September as Flare and Sunburst, and OpenAI held token pricing flat against gpt-image-2. That means picking a model moves your bill by nothing on the rate card. The quality parameter moves it from $0.006 to $0.211 per image — and it defaults to auto.
Read story →OpenAI shipped three new Astra API primitives. Only one has money attached, and OpenAI's own Codex client does not use it
GPT-6 Astra's Responses API gained async tool calling, mid-turn steering and cache-preserving reasoning-effort changes on 3 September 2026. The third one is the only one with a price behind it: Astra bills cache writes at $12.50 per million tokens against $1.00 for cache reads, so changing effort the obvious way costs 12.5x more than changing it via configuration_update. An open bug in OpenAI's own Codex client says it still changes effort the obvious way.
Read story →OpenAI's Assistants API shuts down today — and the next five shutdowns all hand work back to you
The Assistants API sunsets on 26 August 2026, exactly twelve months after notice. Five more OpenAI shutdowns land before 20 January 2027: legacy GPT snapshots on 23 October, Agent Builder and reusable Prompts on 30 November, GPT-5 and o3 snapshots on 11 December, legacy audio and realtime models on 20 January. The retirements are ordinary. The direction is not — every one of them moves state, hosting or tooling from OpenAI's servers onto yours.
Read story →Nvidia's 15% server price rise puts a floor under the AI price war — and the discounts expire first
Bloomberg reported on 22 August 2026 that contract server builders have told Nvidia's largest customers that Grace Blackwell and Vera Rubin systems shipping in early 2027 will cost more than 15% extra, driven by DRAM, LPDDR and HBM4 shortages. Every headline AI price cut of the last month was set when memory was cheap, and the promotional clocks — Sol to 21 November, Gemini 3.7 Flash to 31 December — run out right where the hardware cost increase begins. Here is what that does and does not mean for your 2027 budget.
Read story →DeepSeek bolted vision onto its cheapest model and charged nothing extra — the multimodal price floor just moved
On 21 August 2026 DeepSeek shipped V4-Flash-Vision-Exp, adding image understanding to V4-Flash at identical token rates, with images capped at 384 tokens each and a free Files API. It claims near-parity with Claude Opus 4.8 on several multimodal agent benchmarks. Every one of those numbers comes from DeepSeek's own unreleased harness, and the model carries an explicit experimental label — which makes this a cheap option to evaluate, not a frontier model to migrate to.
Read story →OpenAI cut GPT-5.6 Sol to $4/$20 — and put a 21 November expiry date on the frontier price crown
On 21 August 2026 OpenAI dropped GPT-5.6 Sol from $5/$30 to $4/$20 per million tokens, undercutting Claude Opus 5 on both input and output for the first time. It is explicitly a three-month promotion ending 21 November. Three of the five most-quoted frontier and workhorse prices now carry a hard expiry date, which makes 'who is cheapest' a question with a shelf life — and makes any architecture built around today's answer a liability.
