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 →Cursor's $20 plan is gone — and the models most Cursor users run left the usage pool
On 12 October 2026 SpaceXAI merged Grok, Cursor and X Premium into one five-tier ladder: Free, Plus $8, Premium $30, Super $100, Ultra $200. Cursor Pro at $20 is closed to new signups. The headline is a price cut, but the shared usage pool now covers Grok models only — Claude and GPT in the Cursor editor moved to pass-through API billing on Premium and above. For a developer whose daily driver is Sonnet, a flat $20 bill becomes $30 plus metered tokens.
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 →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 →ChatGPT's new $500 tier did not raise any price — it deleted the only volume discount OpenAI sold
At DevDay on 29 September 2026 OpenAI launched ChatGPT Pro 500 at $500 a month with 25x the Plus allowance, reopened Pro 200, and halved Pro 200's included usage from 20x to 10x effective 30 October. Run the division: every plan in the lineup now costs exactly $20 per unit of Plus allowance. The old Pro 200 was the single exception at $10, and it is the thing that was discontinued.
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 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 →Fireworks priced Ember-1 identically to Kimi K3 — the discount is in the token count, and it expires in two weeks unless enough people use it
Fireworks released Ember-1 on 23 September 2026, a Kimi K3 derivative billed at exactly K3's serverless rate: $3 input, $0.30 cached, $15 output per million tokens. The claimed saving is 35-50% shorter reasoning, so the entire discount lives in token volume rather than the rate card — unverifiable from any pricing page, and shrinking to near zero on input-heavy workloads. It also ships as a two-week research preview that becomes permanent only on community demand.
Read story →OpenAI fixed a vision bug in GPT-6 Sol and Luna three days after launch — and neither model has a dated snapshot to tell the two versions apart
On 25 September 2026 OpenAI's changelog recorded a fix for 'a bug in image encoding that degraded image understanding' in GPT-6 Sol and GPT-6 Luna, released 22 September. Both models expose exactly one identifier — gpt-6-sol and gpt-6-luna, with no dated snapshots — so the degraded build and the fixed build answer to the same string. Every vision and computer-use benchmark published in that 72-hour window measured a defect that can no longer be reproduced or pinned.
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's agent SDK will now run on your own GPU for nothing — the bill just moved from the meter to the VRAM
On 23 September 2026 Google added local model execution to the Antigravity SDK: agent loops running fully offline on LiteRT with Gemma 4 26B A4B, plus plug-and-play support for any OpenAI-compatible server including Ollama, LM Studio and vLLM. Zero token cost, no network. The entry fee is more than 24GB of VRAM or unified memory, and Google's own hybrid demo still sent 2.8% of tokens to the cloud — the 2.8% that does the planning.
