Models
All Claude models available via API — Opus 4.6 (1M context), Opus 4.6, Sonnet 4.6, Haiku 4.5. Stable IDs, short aliases, pricing per token, context windows.
ClaudeStore supports the full Claude lineup via api2.claudestore.store: Claude Opus 4.6 (flagship, 200K standard context, 1M token beta context via anthropic-beta: context-1m-2025), Claude Opus 4.6, Claude Sonnet 4.6, and Claude Haiku 4.5. Short aliases opus, sonnet, haiku always resolve to the latest version of each tier. Pinned IDs (claude-opus-4.6, claude-sonnet-4.6, claude-haiku-4.5) are recommended for production. Billing uses of Anthropic-equivalent token usage.
Recommended Model IDs
Use the stable model IDs listed below in your API requests. These IDs are consistent across both Anthropic and OpenAI-compatible endpoints.
| Model | Model ID | Max Input | Max Output | Thinking | Vision |
|---|---|---|---|---|---|
| Claude Opus 4.6 | claude-opus-4.6 | 200K (1M beta) | 32K | Yes | Yes |
| Claude Opus 4.6 | claude-opus-4.6 | 200K | 32K | Yes | Yes |
| Claude Sonnet 4.6 | claude-sonnet-4.6 | 200K | 16K | Yes | Yes |
| Claude Haiku 4.5 | claude-haiku-4.5 | 200K | 8K | No | Yes |
Legacy model IDs (e.g. claude-sonnet-4.5, claude-opus-4.5, claude-sonnet-4) still resolve for backward compatibility but are not recommended for new integrations.
Short Aliases
For quick experimentation you can use short aliases instead of pinned IDs. Aliases always resolve to the latest version of each tier — convenient for chat clients, risky for production.
| Alias | Resolves to | Recommended for |
|---|---|---|
| opus | claude-opus-4.6 | Quick CLI calls, sandboxes |
| sonnet | claude-sonnet-4.6 | Quick CLI calls, sandboxes |
| haiku | claude-haiku-4.5 | Quick CLI calls, sandboxes |
opus → claude-opus-5.0 when released), which can change behaviour, output length, and pricing without warning.Long Context (1M tokens)
Claude Opus 4.6 supports a 1 million token context window in beta. Enable it by sending the anthropic-beta header on each request:
curl https://api2.claudestore.store/v1/messages \
-H "x-api-key: YOUR_API_KEY" \
-H "anthropic-version: 2023-06-01" \
-H "anthropic-beta: context-1m-2025" \
-H "content-type: application/json" \
-d '{
"model": "claude-opus-4.6",
"max_tokens": 4096,
"messages": [{"role": "user", "content": "."}]
}'Direct Anthropic-equivalent Rates
Claude Code API uses direct Anthropic-equivalent billing, with .
| Model | Input / 1M | Cache write / 1M | Cache read / 1M | Output / 1M |
|---|---|---|---|---|
| Claude Opus 4.6 | $15.00 | $18.75 | $1.50 | $75.00 |
| Claude Opus 4.6 | $15.00 | $18.75 | $1.50 | $75.00 |
| Claude Sonnet 4.6 | $3.00 | $3.75 | $0.30 | $15.00 |
| Claude Haiku 4.5 | $0.80 | $1.00 | $0.08 | $4.00 |
Opus 4.6 pricing matches Opus 4.6 at launch and is subject to change. 1M-context requests use the same rate as 200K-context requests.
Choosing a Model
- Opus 4.6 — flagship reasoning, whole-codebase tasks (1M context), long-form research
- Opus 4.6 — heaviest reasoning at 200K, complex refactors
- Sonnet 4.6 — best value for daily coding, general tasks
- Haiku 4.5 — fastest and cheapest, ideal for autocomplete and classification
