BetaDream object{ id, archived_at, created_at, 11 more }

An asynchronous memory-consolidation job that reads a memory store plus a set of session transcripts and writes consolidated memories into an output memory store — a new store by default, or an existing store chosen via output_behavior. The Dreams API is in research preview: the request and response shapes are volatile and may change without the deprecation period that applies to generally-available endpoints.

BetaDreamError object{ message, type }

Failure detail for a Dream whose status is failed.

message: string
type: string
BetaDreamInput = BetaDreamMemoryStoreInput { memory_store_id, type } or BetaDreamSessionsInput { session_ids, type }

An input memory store the dream reads from. The dream never mutates this store unless it is also the destination: with output_behavior {type: "update_existing"} the job consolidates this store in place.

One of the following:
BetaDreamMemoryStoreInput object{ memory_store_id, type }

An input memory store the dream reads from. The dream never mutates this store unless it is also the destination: with output_behavior {type: "update_existing"} the job consolidates this store in place.

memory_store_id: string
minLength1
type: "memory_store"
BetaDreamSessionsInput object{ session_ids, type }

Input session transcripts the dream reads.

session_ids: array of string
type: "sessions"
BetaDreamMemoryStoreInput object{ memory_store_id, type }

An input memory store the dream reads from. The dream never mutates this store unless it is also the destination: with output_behavior {type: "update_existing"} the job consolidates this store in place.

memory_store_id: string
minLength1
type: "memory_store"
BetaDreamMemoryStoreOutput object{ memory_store_id, type }

An output memory store the dream writes consolidated memories into.

memory_store_id: string
type: "memory_store"
BetaDreamModelConfig object{ id, speed }

Model identifier and configuration applied to every pipeline stage. Same wire shape as the Agents API ModelConfig.

id: string

Model identifier, e.g. "claude-opus-5". 1-256 characters.

minLength1
maxLength256
speed: optional "standard" or "fast"

Inference speed mode. fast provides significantly faster output token generation at premium pricing. Not all models support fast; invalid combinations are rejected at create time.

One of the following:
"standard"
"fast"
BetaDreamModelConfigParam object{ id, speed }

Model identifier and configuration applied to every pipeline stage.

id: string

Model identifier, e.g. "claude-opus-5". 1-256 characters.

minLength1
maxLength256
speed: optional "standard" or "fast" or null

Inference speed mode. fast provides significantly faster output token generation at premium pricing. Not all models support fast; invalid combinations are rejected at create time.

One of the following:
"standard"
"fast"
BetaDreamOutput object{ memory_store_id, type }

An output memory store the dream writes consolidated memories into.

memory_store_id: string
type: "memory_store"
BetaDreamSessionsInput object{ session_ids, type }

Input session transcripts the dream reads.

session_ids: array of string
type: "sessions"
BetaDreamStatus = "pending" or "running" or "completed" or 2 more

Lifecycle status of a Dream.

One of the following:
"pending"
"running"
"completed"
"failed"
"canceled"
BetaDreamUsage object{ cache_creation_input_tokens, cache_read_input_tokens, input_tokens, output_tokens }

Cumulative token usage for the dream across every pipeline stage.

cache_creation_input_tokens: number

Total tokens used to create prompt-cache entries (sum of all TTL tiers).

formatint32
cache_read_input_tokens: number

Total tokens read from prompt cache.

formatint32
input_tokens: number

Total uncached input tokens consumed across every pipeline stage.

formatint32
output_tokens: number

Total output tokens generated across every pipeline stage.

BetaDreamingError = BetaInvalidRequestError { message, type } or BetaAuthenticationError { message, type } or BetaBillingError { message, type } or 7 more

The output_behavior.memory_store_id target is still held by a prior {type: "update_existing"} dream — one that is pending or running, or was canceled with its final writes still landing. Rarely the named dream has just finished (completed/failed) and its execution is still closing; an immediate retry then almost always succeeds. The message names the holding dream when the server can identify it (rarely omitted); poll it to a terminal state or cancel it, then retry. Carried with x-should-retry: false.

One of the following:
BetaOutputBehavior = BetaOutputBehaviorCreateNew { type } or BetaOutputBehaviorUpdateExisting { memory_store_id, type }

The default destination: the job creates a new output memory store as a clone of the memory_store input and writes the consolidated memories into it. The input store is never mutated.

One of the following:
BetaOutputBehaviorCreateNew object{ type }

The default destination: the job creates a new output memory store as a clone of the memory_store input and writes the consolidated memories into it. The input store is never mutated.

type: "create_new"
BetaOutputBehaviorUpdateExisting object{ memory_store_id, type }

The job writes the consolidated memories into this existing memory store instead of creating one. In EAP the store must be the job's own memory_store input, so the job consolidates the store in place.

memory_store_id: string
minLength1
type: "update_existing"
BetaOutputBehaviorCreateNew object{ type }

The default destination: the job creates a new output memory store as a clone of the memory_store input and writes the consolidated memories into it. The input store is never mutated.

type: "create_new"
BetaOutputBehaviorUpdateExisting object{ memory_store_id, type }

The job writes the consolidated memories into this existing memory store instead of creating one. In EAP the store must be the job's own memory_store input, so the job consolidates the store in place.

memory_store_id: string
minLength1
type: "update_existing"
BetaTargetStoreHeldError object{ type, message }

The output_behavior.memory_store_id target is still held by a prior {type: "update_existing"} dream — one that is pending or running, or was canceled with its final writes still landing. Rarely the named dream has just finished (completed/failed) and its execution is still closing; an immediate retry then almost always succeeds. The message names the holding dream when the server can identify it (rarely omitted); poll it to a terminal state or cancel it, then retry. Carried with x-should-retry: false.

type: "conflict_error"
message: optional string

Human-readable description of the conflict, naming the dream that holds the target store when the server can identify it.
