Available Models
- Default = the value used when the field is omitted.
- Effort applies to Anthropic models only — GPT, Grok, and open-source models ignore it (shown as
—). On those models everyeffortlevel collapses to the same variant, so it has no effect. - Newer Anthropic models (Opus 4.6 / 4.7 / 4.8 / 5 / 5.5, Sonnet 4.6 / 5, Fable 5 / 5.1) set thinking automatically, so their
reasoningfield is ignored (shown as auto). - Writing a level a model does not support, such as
xhighongpt-5-2ormaxonkimi-k3, falls back tolowand surfaces a warning.
Open-source models are opt-in and typically cost a fraction of the frontier options — a good fit for specialized, high-volume, or narrowly-scoped work, while Opus remains the default where the strongest model matters.
Open-source models are served through Fireworks AI’s hosted inference — Macroscope does not run local or self-hosted models, and you cannot point at your own endpoints. As we expand the set of inference providers we support, capacity fluctuations from these providers (during heavy load) mean latency may occasionally be higher due to request queuing.

Pricing
Raw model cost, USD per 1M tokens. The four columns are the four token counts a request is metered on, and they do not overlap — each token is counted once:- Input — prompt tokens read fresh, with no cache involved.
- Output — everything the model generated, reasoning tokens included.
- Cache write — prompt tokens written into the provider’s prompt cache. — means the provider charges nothing to create a cache entry.
- Cached input — prompt tokens read back out of the cache instead of re-read.
gpt-5-6-sol is gpt-5.6-sol there, grok-4-6 is grok-4.6, and the open-source models appear under vendor paths such as moonshotai/Kimi-K3.
Large prompts bill at a higher rate on some models. Crossing the threshold reprices the whole request, not just the tokens past it. “Prompt tokens” means uncached input plus cached input plus cache writes.
