Every launch, price move, deprecation and retirement we track — newest first.
Anthropic's deprecations table now states Current state = Retired for claude-opus-4-1-20250805, with Deprecated June 5, 2026 and Retirement August 5, 2026 — exactly the date announced two months earlier. Calls to claude-opus-4-1-20250805 (and the claude-opus-4-1 alias) no longer serve; Anthropic's recommended replacement is claude-opus-4-8. Opus 4.1 was $15 in / $75 out per 1M tokens, 200K context, 32K max output. Caught by scripts/check-lifecycle-drift.mjs on 2026-08-06 — the provider's declared status flipped while our catalog still read 'deprecated'. Worth noting for anyone building on rate data: this event is invisible to a price diff, because the price never changed — the endpoint simply stopped existing.
source ↗Google's deprecations table now names gemini-3.6-flash — not gemini-3.5-flash — as the recommended replacement for gemini-2.5-flash (shutdown 2026-10-16), gemini-2.5-flash-preview-05-20, gemini-2.5-flash-preview-09-25, and the whole gemini-2.0-flash line (gemini-2.0-flash and gemini-2.0-flash-001, both shut down 2026-06-01). The new target is CHEAPER on output than the old one: Gemini 3.6 Flash is $1.50 in / $7.50 out per 1M (context caching $0.15) against Gemini 3.5 Flash's $1.50 / $9.00 at the same input price, so the two Flash rows are not a straight ladder. Gemini 3.6 Flash is GA/stable, 1,048,576-token context, 65,536 max output, text+image+video+audio+PDF input; Google publishes no knowledge cutoff or release date for it. Catalog corrected and gemini-3.6-flash added the same day.
source ↗Google released two new embodied-reasoning endpoints for robotics in public preview: gemini-robotics-er-2-preview (advanced spatial reasoning, agentic code execution, multi-step tool orchestration, video moment finding, progress classification, multi-robot coordination) and gemini-robotics-er-2-streaming-preview (real-time text streaming over the Live API for low-latency robot agents with bidirectional audio and video input). Both accept text, image, video and audio input, output text, and carry 131,072-token input / 65,536-token output limits. Paid-tier standard rates are $2.00/M in and $10.00/M out for both — 2x the input and 2x the output of Gemini Robotics-ER 1.6 ($1.00/$5.00). Only the non-streaming endpoint publishes a context-caching rate ($0.20/1M) and a batch tier ($1.00/$5.00). Google's own upgrade guidance is to replace model="gemini-robotics-er-1.6-preview" with either ER 2 endpoint; ER 1.6 is shut down 2026-08-31.
source ↗Google shipped stable, production-ready Gemini 3.6 Flash and Gemini 3.5 Flash-Lite on the same day. Gemini 3.5 Flash-Lite (gemini-3.5-flash-lite) is billed at $0.30/M in and $2.50/M out on the paid tier, context caching $0.03/M, batch $0.15/$1.25 — against gemini-3.1-flash-lite's $0.25/$1.50, i.e. the recommended migration target is more expensive on both sides, unusually for a Flash-Lite step. One offsetting simplification: 3.5 Flash-Lite publishes a SINGLE input rate covering text, image, video and audio, where 3.1 and 2.5 Flash-Lite both charged a higher audio-input tier. 1,048,576-token context, 65,536 max output, text/image/video/audio/PDF in, text out; computer use in preview. Google's deprecations table names it the recommended replacement for gemini-3.1-flash-lite, which shuts down 2027-05-07. No shutdown date announced for 3.5 Flash-Lite itself.
source ↗OpenAI's GPT-5.6 generation went GA on the API + Codex on 2026-07-09 (preview from 06-26), in three durable capability tiers: Sol (flagship) $5 in / $30 out, Terra (balanced) $2.50 / $15, Luna (fast, high-volume) $1 / $6 — all per 1M tokens, cached input $0.50 / $0.25 / $0.10. Every tier has a 1.05M-token context window, 128K max output, text + image input, and a 2026-02-16 knowledge cutoff. Sol matches GPT-5.5's price but is stronger on coding, knowledge work, cybersecurity and science. New caching model: explicit cache breakpoints, 30-min minimum cache life, cache writes billed 1.25x uncached input.
source ↗xAI's smartest model for chat, coding, agentic and knowledge work. Base pricing $2 input / $6 output per 1M tokens (cached input $0.50), tiered 2x above a 200K-token prompt. 500K context window (down from Grok 4.3's 1M), text + image input. Public API access opened 2026-07-09; aliases grok-4.5-latest / grok-build-latest.
source ↗Anthropic's most agentic Sonnet, with performance close to Opus 4.8 at lower cost. Standard pricing $3 input / $15 output per 1M tokens, with introductory pricing of $2/$10 in effect through 2026-08-31. 1M context window, 128k max output, Jan 2026 knowledge cutoff. Supersedes Claude Sonnet 4.6, now a legacy model.
source ↗Mistral released Leanstral 1.5, a specialist model for Lean 4 formal proof engineering, automated theorem proving and autoformalization (not a general chat model). Sparse MoE 119B total / 6.5B active, 256K context, 128K max output, text + image input. Open weights under Apache 2.0. Offered FREE in Mistral's experimental Labs tier ($0/M in and out), with a stated retirement of 2026-09-30 — the catalog's first $0 model, recorded as preview (Labs/experimental) so it stays out of the GA 'cheapest' rankings.
source ↗Tracking 181 models across 12 providers.
Mistral deprecated its frontier reasoning model (magistral-medium-2509, $2/$5 per MTok, 128k context). Migrate to Mistral Medium 3.5 — Mistral is folding its specialist reasoning line back into its general-purpose models rather than shipping a Magistral successor.
source ↗Mistral deprecated its frontier agentic-coding model (devstral-2512, $0.4/$2 per MTok, 256k context, open weights under a Modified MIT licence). Migrate to Mistral Medium 3.5 — the specialist coding line is being folded back into the general-purpose models.
source ↗Mistral deprecated its small reasoning model (magistral-small-2509, $0.5/$1.5 per MTok, 128k context, Apache-2.0 weights, 24B). Migrate to Mistral Small 4.
source ↗Video generation (Videos API). Priced per second, not per token: sora-2 $0.10/s (720p, standard) / $0.05/s batch. Videos API + sora-2* announced for discontinua
source ↗Higher-quality video model. Per-second pricing: $0.30/s (720p) up to $0.70/s (1080p) standard; batch half. Discontinued with Videos API, shuts down 2026-09-24,
source ↗Mistral deprecated its small agentic-coding model (labs-devstral-small-2512, $0.1/$0.3 per MTok, 256k context, Apache-2.0 weights, 24B). Migrate to Mistral Medium 3.5. Its stated 2026-03-31 retirement has passed, but Mistral still lists the model as deprecated rather than retired and still prices it publicly.
