View on XOpenRouter Launches Claude Opus 4.7 Fast Mode for High Speed Reasoning
OpenRouter· Updated
OpenRouter enabled a high-speed inference tier for Anthropic's flagship model, delivering 2.5x faster throughput at a 6x price premium. This update allows developers to trade capital for speed in latency-sensitive agentic workflows without sacrificing reasoning depth.
OpenRouter, a unified API platform for accessing hundreds of LLMs, launched a "fast mode" variant of Anthropic's flagship model, Claude Opus 4.7. This high-speed inference (running a model to generate outputs) tier delivers 2.5x faster throughput while maintaining the model's original intelligence and 1-million-token context window.
- Throughput
- ~2.5x faster than standard
- Context window
- 1,000,000 tokens
- Max output
- 128,000 tokens
- Pricing (input)
- $30 per million tokens
- Pricing (output)
- $150 per million tokens
- Availability
- OpenRouter API
Latency is the primary bottleneck for autonomous workflows requiring sequential reasoning steps. While Opus 4.7's tokenizer previously impacted costs, this update introduces a deliberate trade-off between speed and capital. It mirrors the industry shift toward specialized inference tiers where performance is optimized for high-volume production agents.
Access the tier via the anthropic/claude-opus-4.7-fast model ID. It is priced at a 6x premium of $30 per million input tokens and $150 per million output tokens. This is effective for asynchronous agent pipelines where task completion speed is more valuable than per-token cost efficiency.
Still wondering? A few quick answers below.
Claude Opus 4.7 Fast is a high-speed inference variant of Anthropic's flagship model available through the OpenRouter API. It provides the same intelligence and reasoning capabilities as the standard Opus 4.7 but is optimized for significantly higher output speeds, making it ideal for latency-sensitive applications like autonomous agents and real-time coding assistants.
This high-speed tier carries a premium 6x price increase compared to the standard model. On OpenRouter, it is priced at $30 per million input tokens and $150 per million output tokens. There are also specific costs for caching, with cache reads priced at $3 per million tokens and cache writes at $37.50 per million tokens.
Claude Opus 4.7 Fast delivers approximately 2.5x faster throughput than the standard version of the model. While the underlying intelligence remains identical, this increased speed reduces the time it takes for the model to generate text, which is a critical factor for complex, multi-step agentic workflows that require rapid sequential processing.
The model features a massive 1-million-token context window, allowing it to process entire codebases or long documents in a single request. It supports a maximum output of 128,000 tokens per response. These specifications are identical to the standard Opus 4.7, ensuring that users do not lose capacity when switching to the faster tier.
To use this model, developers should set their model identifier to anthropic/claude-opus-4.7-fast within their OpenRouter API requests. The platform normalizes these requests across providers, supporting standard parameters like max tokens and tool choice. It also supports reasoning tokens, which allow users to monitor the model's internal thinking process during complex tasks.
