Specifications

Provider-documented facts. “Not collected” means we have not verified that field yet, not that the feature is unsupported.

Context / input limit
Not collected
Maximum output
Not collected
Reasoning
Not collected
Tool calling
Not collected

Agent orchestration, hosted GLM tools and built-in web grounding do not establish arbitrary function calling by this model.

Structured output
Not collected

A structured API response envelope is not schema-constrained model text output.

Streaming
Not collected

Polling generation status does not establish progressive output streaming.

Batch processing
Not collected

Asynchronous jobs and concurrent requests do not establish a dedicated Batch API.

Fine-tuning
Not collected
Knowledge cutoff
Not collected
Release date

Parameters

Architecture

Languages

Context caching
Not collected

Reusable uploaded media and expiring download links do not establish model-inference caching or discounted cache rates.

Aspect ratios
1:1, 3:4, 4:3, 9:16, 16:9, 9:21, 21:9Source for Aspect ratios (opens in a new tab)

Access & pricing

Prices belong to an endpoint and billing tier. A provider listing does not guarantee access for every account or region.

API model ID
photon-1
Access
Legacy API remains documented, but Luma says Photon is no longer a separate product. Current account availability is untested.
Regions
Not collected
API endpoint URL
POST https://api.lumalabs.ai/dream-machine/v1/generations/imageSource for API endpoint URL (opens in a new tab)

Endpoint pricing has not been collected. Check the provider for applicable rates.

Data & enterprise terms

Retention, training use, regional processing and enterprise terms have not been summarized for this endpoint.

Caching

Caching can reuse earlier input processing. Availability, lifetime and billing depend on the endpoint. A cache hit still generates a new response.

01 / INITIAL INPUTProcess & retain

The system processes eligible input and retains reusable state.

02 / LATER REQUESTCheck available state

Reuse depends on matching input, session state and the cache policy.

03 / CACHE HITReuse & generate

Reusing state can reduce repeated work. Any charges follow the billing rules below.

No verified cache rate for this endpoint. An empty rate is not a zero charge.

What the measurements say

No benchmark observations have been added for this model. We do not turn a vendor description into a performance score.

Latency and throughput depend on the host, request size, reasoning settings and load. There is no measured speed or global usage figure in this record.

The record behind the model

Why it is included

Inferred from the named Luma-hosted proprietary service, terms restricting access to underlying models and weights, and the separate official public-checkpoint inventory (IMM and TVM). This is release-specific catalog classification, not an assertion that all Luma research is closed.
