Refresh the LiteLLM provider/model catalog and pricing, and fix
--write-rust-snapshot so it no longer clobbers the hand-maintained
ANTHROPIC_ADAPTIVE_ONLY_THINKING_MODELS list. Running the generator
previously overwrote the whole file and silently dropped that constant,
breaking the build until it was hand-restored.
- Pricing: refresh assets/model_pricing.json + proxy copy from LiteLLM
(177 -> 169 entries; +claude-opus-5, gemini-3.5/3.6-flash,
gemini-omni-flash-preview; -14 gpt-*-realtime*; price changes on
gpt-5.6-luna, gpt-5.6-terra).
- Snapshot: regenerate litellm_snapshot.rs; claude-opus-5 (released
2026-07-24) is now in the data-driven ADAPTIVE_THINKING / MAX / XHIGH
lists from upstream, which matches its documented high/xhigh/max support.
- Generator (the fix): emit ANTHROPIC_ADAPTIVE_ONLY_THINKING_MODELS from a
new ANTHROPIC_ADAPTIVE_ONLY_THINKING Python constant in
check_litellm_providers.py, so litellm_snapshot.rs is 100% generated and
the constant survives every regeneration. Add claude-opus-5 and
claude-sonnet-5, which reject thinking.type:"enabled"/budget_tokens with
a 400 (adaptive-only) per Anthropic's "Configurations each model rejects"
table. Not derivable from LiteLLM flags (extended_thinking is true for
every thinking model), so it stays hand-curated in the script.
- Tests: bump anthropic catalog count 23 -> 24; assert opus-5 and sonnet-5
require adaptive thinking (reject budget_tokens).
- Docs: correct the stale "hand-maintained tail" gotcha in
crates/providers/CLAUDE.md; add Opus 5/Sonnet 5 to the reject-list note.
Verified: idempotent regen (two runs byte-identical), cargo fmt --check
clean, cargo clippy (default features, as CI runs) clean, cargo test
--workspace 1728 passed / 0 failed / 10 ignored (live-API).

Phases 12-18: release infrastructure (LICENSE, README, Dockerfile, CI,
CHANGELOG), transparent proxy with anthropic-version/anthropic-beta header
passthrough and lossy translation warnings, BIG_MODEL/SMALL_MODEL env-based
model mapping, mTLS client cert support (P12/PEM), max_completion_tokens
and reasoning_effort passthrough via serde flatten, extended thinking type
support (thinking blocks stripped in translation), top_k typed field.
Phase 20: Gemini backend research with docs/gemini-api-diffs.md covering
native API format, tool calling, streaming, auth, schema restrictions,
and Vertex AI OpenAI-compatible endpoint. Task roadmap through Phase 22.
Test count: 169 -> expanded with new fixture and unit tests for all phases.
