Defined in: evaluator/LlamaContext/LlamaContext.ts:186

Returns

LlamaModel

contextSize

Get Signature

get contextSize(): number

Defined in: evaluator/LlamaContext/LlamaContext.ts:190

Returns

number

---

batchSize

Get Signature

Defined in: evaluator/LlamaContext/LlamaContext.ts:194

Returns

number

---

flashAttention

Get Signature

get flashAttention(): boolean

Defined in: evaluator/LlamaContext/LlamaContext.ts:198

Returns

boolean

---

stateSize

Get Signature

get stateSize(): number

Defined in: evaluator/LlamaContext/LlamaContext.ts:206

The actual size of the state in the memory in bytes. This value is provided by llama.cpp and doesn't include all the memory overhead of the context.

Returns

number

---

currentThreads

Get Signature

get currentThreads(): number

Defined in: evaluator/LlamaContext/LlamaContext.ts:213

The number of threads currently used to evaluate tokens

Returns

number

---

idealThreads

Get Signature

get idealThreads(): number

Defined in: evaluator/LlamaContext/LlamaContext.ts:224

The number of threads that are preferred to be used to evaluate tokens.

The actual number of threads used may be lower when other evaluations are running in parallel.

Returns

number

---

totalSequences

Get Signature

get totalSequences(): number

Defined in: evaluator/LlamaContext/LlamaContext.ts:237

Returns

number

---

sequencesLeft

Get Signature

get sequencesLeft(): number

Defined in: evaluator/LlamaContext/LlamaContext.ts:241

Returns

number

Methods

dispose()

dispose(): Promise<void>

Defined in: evaluator/LlamaContext/LlamaContext.ts:168

Returns

Promise<void>

---

getAllocatedContextSize()

getAllocatedContextSize(): number

Defined in: evaluator/LlamaContext/LlamaContext.ts:228

Returns

number

---

getSequence()

getSequence(options: {
  contextShift: ContextShiftOptions;
  tokenPredictor: TokenPredictor;
 }): LlamaContextSequence

Defined in: evaluator/LlamaContext/LlamaContext.ts:249

Before calling this method, make sure to call sequencesLeft to check if there are any sequences left. When there are no sequences left, this method will throw an error.

Parameters

Parameter	Type	Description
options	{ contextShift: ContextShiftOptions; tokenPredictor: TokenPredictor; }	-
options.contextShift?	ContextShiftOptions	-
options.tokenPredictor?	TokenPredictor	Token predictor to use for the sequence. Don't share the same token predictor between multiple sequences. Using a token predictor doesn't affect the generation output itself - it only allows for greater parallelization of the token evaluation to speed up the generation. > Note: that if a token predictor is too resource intensive, > it can slow down the generation process due to the overhead of running the predictor. > > Testing the effectiveness of a token predictor on the target machine is recommended before using it in production. Automatically disposed when disposing the sequence. See Using Token Predictors

Returns

LlamaContextSequence

dispatchPendingBatch()

dispatchPendingBatch(): void

Defined in: evaluator/LlamaContext/LlamaContext.ts:300

Returns

void

---

printTimings()

printTimings(): Promise<void>

Defined in: evaluator/LlamaContext/LlamaContext.ts:608

Print the timings of token evaluation since that last print for this context.

Requires the performanceTracking option to be enabled.

Note: it prints on the LlamaLogLevel.info level, so if you set the level of your Llama instance higher than that, it won't print anything.

Returns

Promise<void>
