Via SoleAPI, Input (prompt) costs 6.4 Credits / M tokens, 76% below list price. Compatible with Anthropic Messages / Gemini generateContent: swap the base URL and you are connected.
Capabilities
Listed exactly as the catalog flags them, including what this model does not support.
Vision
Natively multimodal: captioning, classification, visual Q&A, chart and screenshot understanding. Images are converted to tokens at the input rate.
Function Calling
Connect the model to external tools and APIs: it decides when to call which function and with what arguments, your code runs it. Force or forbid calls with tool_choice.
Reasoning
The model thinks before answering, which markedly improves multi-step planning and reasoning for coding, math and data analysis. Thinking tokens bill at the output rate.
Prompt Caching
Repeated prefixes (system prompts, long documents) hit the cache: reads cost far less than input, writes are priced by retention time.
Response Schema
Constrain output to a JSON Schema you provide for predictable, type-safe results without parsing free text.
Audio
Audio input or speech output.
Video
Video input understanding or video generation.
File Input
Upload PDFs and other documents directly; the model reads the whole document with native vision.
Streaming
Tokens arrive over SSE as they are generated; the first frame is forwarded immediately with no buffering. Claude Code, Codex and similar tools depend on this.
Web Search
Vendor-hosted live web retrieval; the model decides when to search and cites sources.
RealtimeNot supported
Bidirectional low-latency voice / text sessions over WebSocket.
SessionNot supported
Server-side multi-turn context (e.g. previous_response_id in Responses) so you need not resend history.
MediaNot supported
Image / video / music generation endpoints.
Multipart FormNot supported
multipart/form-data file-upload requests.
Binary ResponseNot supported
Endpoints that return raw audio / image bytes.
Protocols & code samples
Change the base URL to SoleAPI, keep everything else. Native protocols pass straight through; “adapted” ones are translated by the gateway.
Anthropic SDK or any Messages-protocol client: point base_url at https://api.soleapi.com and use a SoleAPI key.

List price → SoleAPI price per channel, every pricing dimension, nothing hidden.
| Item | Unit | Google list price | Official Gemini Group ×1.676% off |
|---|---|---|---|
| Input (prompt) | per 1M tokens | 6.4 Credits | |
| Output (completion) | per 1M tokens | 32 Credits | |
| Cache read | per 1M tokens | 0.32 Credits | |
| Web search (general) | per 1K calls | 22.4 Credits |
“Off” is computed at 1 Credit = ¥1 and today’s rate: 1 − channel multiplier × (1 Credit in the list currency). Priority: when request body field service_tier matches ^priority$, billed at Cache read ×1.8、Output (completion) ×1.8、Input (prompt) ×1.8、other items ×1.8; stacks with any channel.
