Claude Model Catalog
Only use exact model IDs listed in this file. Never guess or construct model IDs — incorrect IDs will cause API errors. Use aliases wherever available. For the latest information, WebFetch the Models Overview URL in shared/live-sources.md, or query the Models API directly (see Programmatic Model Discovery below).
Programmatic Model Discovery
For live capability data — context window, max output tokens, feature support (thinking, vision, effort, structured outputs, etc.) — query the Models API instead of relying on the cached tables below. Use this when the user asks "what's the context window for X", "does model X support vision/thinking/effort", "which models support feature Y", or wants to select a model by capability at runtime.
m = client.models.retrieve("claude-opus-4-8")
m.id
m.display_name
m.max_input_tokens
m.max_tokens
caps = m.capabilities
caps["image_input"]["supported"]
caps["thinking"]["types"]["adaptive"]["supported"]
caps["effort"]["max"]["supported"]
caps["structured_outputs"]["supported"]
caps["context_management"]["compact_20260112"]["supported"]
[m for m in client.models.list()
if m.capabilities["thinking"]["types"]["adaptive"]["supported"]
and m.max_input_tokens >= 200_000]
Top-level fields (id, display_name, max_input_tokens, max_tokens) are typed attributes. capabilities is a dict — use bracket access, not attribute access. The API returns the full capability tree for every model with supported: true/false at each leaf, so bracket chains are safe without .get() guards. TypeScript SDK: same method names, also auto-paginates on iteration.

Model Descriptions
- Claude Opus 4.8 — The most capable Claude model to date — highly autonomous, state-of-the-art on long-horizon agentic work, knowledge work, and memory; clearer, warmer writing. Same API surface as Opus 4.7 (adaptive thinking only; sampling parameters and
budget_tokens removed). 1M context window at standard API pricing (no long-context premium). See shared/model-migration.md → Migrating to Opus 4.8 — a 4.7 → 4.8 move is a model-ID swap plus prompt re-tuning, no new breaking changes.
- Claude Opus 4.7 — Previous-generation Opus. Highly autonomous; strong on long-horizon agentic work, knowledge work, vision, and memory. Adaptive thinking only; sampling parameters and
budget_tokens removed. 1M context window. See shared/model-migration.md → Migrating to Opus 4.7.
- Claude Opus 4.6 — Older Opus. Supports adaptive thinking (recommended), 128K max output tokens (requires streaming for large outputs). 1M context window.
- Claude Sonnet 4.6 — Our best combination of speed and intelligence. Supports adaptive thinking (recommended). 1M context window. 64K max output tokens.
- Claude Haiku 4.5 — Fastest and most cost-effective model for simple tasks.
