This file is an optional snapshot of the latest automated audit whose per-model results add useful context for a future run. It is orientation only; reconfirm every price and tier against official provider sources before making a change or reporting a row as confirmed.
The audit agent may replace the snapshot below with its complete current table. Keep only one snapshot, never append an unbounded run history, never persist a partial set of checked models, and do not update this file only to refresh the audit date.
Audit date: 2026-09-02
All prices listed as $X / MTok (per million tokens). Per-token JSON values: divide by 1,000,000.
The 2026-09-02 run re-fetched the full Anthropic pricing table (plus the models-overview
table, model-deprecations page, and the dedicated Mythos 5.1 page), the full OpenAI
standard/Fast-mode/Flex pricing tables (plus dedicated pages for gpt-5.6-sol,
gpt-5.3-codex, and gpt-5.6-cyber), and the Gemini AI Studio pricing/models pages
(with explicit Free/Paid column separation). Three new models were found and added:
claude-fable-5-1, claude-mythos-5-1, and gemini-3.8-flash. One existing entry
gained a previously undocumented tier: gpt-5.3-codex (Fast mode). One specialized
model was found and deliberately left unadded: gpt-5.6-cyber (restricted
cybersecurity endpoint, Daybreak-program-gated). All other checked rows were
reconfirmed unchanged from the 2026-08-24 snapshot.

| Anthropic | claude-fable-5-1 | Input $10/MTok, Output $50/MTok, 5m $12.50/MTok, 1h $20/MTok, read $0.25/MTok (0.025x, not the standard 0.1x) | Yes | Flat 1M context; no Fast mode | Yes | Added | https://platform.claude.com/docs/en/about-claude/pricing https://platform.claude.com/docs/en/models/overview | New model, now Anthropic's recommended choice for "demanding reasoning and long-horizon agentic work" (ahead of Fable 5, now listed as legacy). Cache-read discount is 0.025x per an explicit page footnote, not the usual 0.1x. matchPattern mirrors claude-fable-5 with a -1 suffix. |

Legacy Claude 3.x / 3.5 / 3.7 models not on the current pricing page — Not
re-verified this run (claude-3.7-sonnet-20250219, claude-3.5-sonnet-20241022,
claude-3-5-sonnet-20240620, claude-3-opus-20240229, claude-3-sonnet-20240229,
claude-3-haiku-20240307). Existing prices retained. Low priority, retired/legacy.
gemini-3.1-flash-lite-preview and gemini-3-pro-preview — Still not separately listed on the official AI Studio pricing or models pages. Existing prices retained without fresh confirmation. Re-verify if these move from preview to GA.
gemini-3.6-flash / gemini-3.7-flash / gemini-3.8-flash promotional pricing reverts
2027-01-01 — All three models are confirmed on introductory pricing ($0.75/$3.75/MTok
input/output, $0.075/MTok cache read) "through December 31, 2026," stepping up to
$1.50/$7.50/$0.15 "starting January 1, 2027." The pricing file currently holds the
discounted price (correct for now); update all three entries to the higher rate on or
after 2027-01-01. Same time-based-tiering limitation previously seen with
claude-sonnet-5 — Langfuse's schema cannot express a calendar-date price step, so the
file always holds the currently active rate.
OpenAI "cache writes" is still gpt-5.6-family-only (now four members) — The
distinct 1.25x-of-input cache-write billing dimension applies to gpt-5.6-sol,
gpt-5.6-terra, gpt-5.6-luna, and the newly found (but deliberately unadded)
gpt-5.6-cyber. Every other checked OpenAI model still shows "—" for cache writes.
Re-check this column whenever a new OpenAI reasoning model is added.
Base vs. fine-tuning legacy pricing confusion is a real historical bug class — See
the davinci-002/babbage-002 fix (Aug 7 2026). When auditing any OpenAI base model that
also has a legacy fine-tuning tier (gpt-3.5-turbo, davinci-002, babbage-002, and
the fine-tunable snapshots gpt-4.1-2025-04-14, gpt-4.1-mini-2025-04-14,
gpt-4.1-nano-2025-04-14, gpt-4o-2024-08-06, gpt-4o-mini-2024-07-18,
o4-mini-2025-04-16), confirm which table a fetched price came from before applying it
to the bare (non-ft:) entry.
Legacy/embedding/base-completion catalog tail not covered this run — Entries such
as text-ada-001, text-babbage-001, text-curie-001, text-davinci-00{1,2,3},
text-embedding-*, the Vertex *-bison*/*-gecko* PaLM family, claude-1.x/claude-2.x,
and gemini-1.0-*/gemini-pro were not re-fetched this run, consistent with prior
audits, since they are long-retired and out of the "flagship text/chat/reasoning model"
scope.
Gemini and OpenAI specialized-modality/restricted-access model waves confirmed out
of scope — gemini-omni-flash, gemini-3.1-flash-live-preview,
gemini-3.1-flash-tts-preview, gemini-3.5-live-translate-preview, the
veo-3.1-*-generate-preview pair, the lyria-3-*/lyria-realtime-exp family, and
gemini-robotics-er-2-preview (found 2026-08-21, video/audio/TTS/music/robotics
endpoints) plus gpt-5.6-cyber and the gpt-daybreak-*-latest aliases (found
2026-09-02, a gated specialized cybersecurity endpoint and floating aliases). None
were added, per the automated-audit rule to skip modality-specific or
restricted-access endpoints. Re-investigate only if one of them gains a standard
text-generation mode with open access and its own per-token text pricing.
Selectable models with no matching pricing regex — confirmed still a known,
intentional gap — Last fully cross-checked 2026-08-24: gemini-1.5-pro,
gemini-1.5-flash, gemini-1.5-flash-8b, gemini-2.0-pro-exp-02-05,
gemini-2.0-flash-exp, gemini-2.0-flash-thinking-exp-01-21,
gemini-2.5-flash-preview-09-2025, gemini-2.5-flash-lite-preview-09-2025 have no
matching pricing entry — retired/experimental IDs with no official pricing page
entry, not a new finding. Not re-run this cycle (no new selectable model was added to
types.ts outside the ones this audit itself added, which do have matching entries).
