feat: add claude-opus-4.8 and claude-opus-4.8-fast (#34003) 
Anthropic released Claude Opus 4.8 on 2026-05-27, available on
OpenRouter, Anthropic, Amazon Bedrock, and Claude Platform on AWS:
  - https://openrouter.ai/anthropic/claude-opus-4.8
  - https://openrouter.ai/anthropic/claude-opus-4.8-fast

The fast-mode variant is a separate model ID (anthropic/claude-opus-4.8-fast)
priced at 2x of the base model — a notable improvement over the 6x premium
on older Opus generations (4.6/4.7). It is NOT a `speed: "fast"` request
parameter like Opus 4.6; Anthropic's native fast-mode beta still only
covers Opus 4.6.

Changes:

  hermes_cli/models.py
    - Add anthropic/claude-opus-4.8 + anthropic/claude-opus-4.8-fast to
      the OpenRouter fallback snapshot and the Nous Portal curated list
      (live catalogs surface them automatically when reachable; the
      fallback list matters when the manifest fetch fails).
    - Add claude-opus-4-8 to the Anthropic-native picker list.

  agent/model_metadata.py
    - Register claude-opus-4-8 / claude-opus-4.8 in DEFAULT_CONTEXT_LENGTHS
      with 1M tokens (matches 4.6/4.7).

  agent/anthropic_adapter.py
    - Extend _XHIGH_EFFORT_SUBSTRINGS, _ADAPTIVE_THINKING_SUBSTRINGS, and
      _NO_SAMPLING_PARAMS_SUBSTRINGS with "4-8"/"4.8". 4.8 inherits the
      Opus 4.7 API contract: adaptive thinking only, xhigh effort level
      supported, sampling parameters (temperature/top_p/top_k) return 400.
    - Add claude-opus-4-8 to _ANTHROPIC_OUTPUT_LIMITS (128k max output,
      same as 4.7). Matches by substring so claude-opus-4-8-fast and
      date-stamped variants resolve correctly.

  agent/usage_pricing.py
    - Add anthropic/claude-opus-4-8: $5/$25 per MTok input/output, $0.50
      cache read, $6.25 cache write (same as 4.6/4.7).
    - Add anthropic/claude-opus-4-8-fast: $10/$50 per MTok (2x), $1.00
      cache read, $12.50 cache write. Per OpenRouter, the 2x premium is
      the only differentiator from regular Opus 4.8.
    - OpenRouter routes still pull pricing from the live /models API, so
      no static OpenRouter entry is needed.

  tests/agent/test_model_metadata.py
    - Extend the Claude 4.6+ context-length tag list with 4.8/4-8.

  website/static/api/model-catalog.json
    - Regenerated via `python scripts/build_model_catalog.py` to pick up
      the new entries in the OpenRouter and Nous Portal fallback lists.

E2E verification (isolated sys.path import against the worktree):
  - _supports_adaptive_thinking, _supports_xhigh_effort, _forbids_sampling_params
    all return True for claude-opus-4.8 and claude-opus-4.8-fast.
  - _supports_fast_mode (the `speed: "fast"` request-parameter gate) stays
    False for 4.8 — fast mode is a separate model ID on OpenRouter, not a
    parameter Anthropic accepts on the base model.
  - DEFAULT_CONTEXT_LENGTHS resolves 1M for both notations.
  - resolve_billing_route + _lookup_official_docs_pricing resolve the
    correct $5/$25 (regular) and $10/$50 (fast) pricing for both
    dot-notation and dash-notation inputs.
  - 4.7 and 4.6 regression: behavior unchanged.

Unit tests: 305 passed across tests/agent/test_usage_pricing.py,
test_model_metadata.py, tests/hermes_cli/test_model_catalog.py,
test_models.py, test_model_validation.py, test_models_dev_preferred_merge.py.

README.md

Website

This website is built using Docusaurus, a modern static website generator.

Installation

yarn

Local Development

yarn start

This command starts a local development server and opens up a browser window. Most changes are reflected live without having to restart the server.

Build

yarn build

This command generates static content into the build directory and can be served using any static contents hosting service.

Deployment

Using SSH:

USE_SSH=true yarn deploy

Not using SSH:

GIT_USER=<Your GitHub username> yarn deploy

If you are using GitHub pages for hosting, this command is a convenient way to build the website and push to the gh-pages branch.

Diagram Linting

CI runs ascii-guard to lint docs for ASCII box diagrams. Use Mermaid (````mermaid`) or plain lists/tables instead of ASCII boxes to avoid CI failures.
