Follow up #640 Ref comments: - #640 (review) by @julien-c suggests using a check `metadata["general.architecture"] === ...` to select the correct type - #640 (comment) by @coyotte508 suggests using less generic but more verbose code The type system introduce in this PR allows type-checking at both compile time & runtime: ```ts const model: GGUFMetadata<GGUFType.STRICT> = null as any; if (model["general.architecture"] === "whisper") { model["encoder.whisper.block_count"] = 0; // @ts-expect-error because it must be a number model["encoder.whisper.block_count"] = "abc"; } if (model["tokenizer.ggml.model"] === undefined) { // @ts-expect-error because it's undefined model["tokenizer.ggml.eos_token_id"] = 1; } if (model["tokenizer.ggml.model"] === "gpt2") { // @ts-expect-error because it must be a number model["tokenizer.ggml.eos_token_id"] = undefined; model["tokenizer.ggml.eos_token_id"] = 1; } if (model["general.architecture"] === "mamba") { model["mamba.ssm.conv_kernel"] = 0; // @ts-expect-error because it must be a number model["mamba.ssm.conv_kernel"] = "abc"; } if (model["general.architecture"] === "llama") { // @ts-expect-error llama does not have ssm.* keys model["mamba.ssm.conv_kernel"] = 0; } ``` Type checks can be disable with `GGUFMetadata<GGUFType.NON_STRICT>`
