Operations 13

Each operation below carries the questions people ask an LLM about it and the instructions they give an agent to run it. Generated by API Evangelist overlay

POST /fine_tuning/alpha/graders/run Run a grader against a model sample · Run a grader #
Ask an LLM
“How do I score a single model output with a grader before fine-tuning?”
“Can I test a grader against a sample and a reference item to see the score it gives?”
Tell an agent
Run grader {grader} on the model sample {model_sample}.
Score {model_sample} with grader {grader} using reference item {item}.
POST /fine_tuning/alpha/graders/validate Check that a grader definition is valid · Validate a grader #
Ask an LLM
“Is my grader configuration valid before I use it in a fine-tuning job?”
“Can I check a grader definition for errors without running it?”
Tell an agent
Validate grader definition {grader}.
Check whether {grader} is a well-formed grader without scoring anything.
GET /fine_tuning/checkpoints/{fine_tuned_model_checkpoint}/permissions List who can use a fine-tuned checkpoint · **NOTE:** This endpoint requires an admin API key. #
Ask an LLM
“Which projects have access to one of my fine-tuned model checkpoints?”
“Can I check whether a specific project was granted a checkpoint?”
Tell an agent
List the sharing permissions on checkpoint {fine_tuned_model_checkpoint}.
Show whether project {project_id} can use checkpoint {fine_tuned_model_checkpoint}.
POST /fine_tuning/checkpoints/{fine_tuned_model_checkpoint}/permissions Share a fine-tuned checkpoint with other projects · **NOTE:** Calling this endpoint requires an admin API key. #
Ask an LLM
“How do I share a fine-tuned model with other projects in my organization?”
“Do I need an admin key to grant a project access to a checkpoint?”
Tell an agent
Share checkpoint {fine_tuned_model_checkpoint} with projects {project_ids}.
Grant projects {project_ids} permission to use fine-tuned checkpoint {fine_tuned_model_checkpoint}.
DELETE /fine_tuning/checkpoints/{fine_tuned_model_checkpoint}/permissions/{permission_id} Revoke a project's access to a checkpoint · **NOTE:** This endpoint requires an admin API key. #
Ask an LLM
“How do I stop another project from using my fine-tuned checkpoint?”
“Can I remove a single sharing permission from a checkpoint?”
Tell an agent destructive · confirm first
Delete permission {permission_id} from checkpoint {fine_tuned_model_checkpoint}.
Revoke sharing grant {permission_id} on fine-tuned checkpoint {fine_tuned_model_checkpoint}.
POST /fine_tuning/jobs Start a fine-tuning job to train a custom model · Creates a fine-tuning job which begins the process of creating a new model from… #
Ask an LLM
“How do I fine-tune a model on my own training file?”
“Can I supply a validation file and custom hyperparameters when I start fine-tuning?”
Tell an agent
Fine-tune {model} on training file {training_file}.
Start a fine-tuning job on {model} with {training_file} and validate against {validation_file}.
GET /fine_tuning/jobs List my organization's fine-tuning jobs · List your organization's fine-tuning jobs #
Ask an LLM
“Which fine-tuning jobs has my organization run?”
“Can I filter fine-tuning jobs by the metadata I tagged them with?”
Tell an agent
List all our fine-tuning jobs.
Show fine-tuning jobs tagged with metadata {metadata}.
GET /fine_tuning/jobs/{fine_tuning_job_id} Get the status of a fine-tuning job · Get info about a fine-tuning job. Learn more about fine-tuning #
Ask an LLM
“Is my fine-tuning job finished, and what is the new model called?”
“Can I look up one fine-tuning job by its ID?”
Tell an agent
Show fine-tuning job {fine_tuning_job_id}.
Check whether fine-tuning job {fine_tuning_job_id} has succeeded.
POST /fine_tuning/jobs/{fine_tuning_job_id}/cancel Cancel a fine-tuning job · Immediately cancel a fine-tune job #
Ask an LLM
“How do I stop a fine-tuning job for good?”
“Can I immediately cancel a fine-tune I started by mistake?”
Tell an agent destructive · confirm first
Cancel fine-tuning job {fine_tuning_job_id}.
Abort fine-tune {fine_tuning_job_id} right now.
GET /fine_tuning/jobs/{fine_tuning_job_id}/checkpoints List the checkpoints a fine-tuning job produced · List checkpoints for a fine-tuning job #
Ask an LLM
“Which intermediate checkpoints did my fine-tuning job save?”
“Can I pick an earlier checkpoint from a fine-tuning run instead of the final model?”
Tell an agent
List the checkpoints for fine-tuning job {fine_tuning_job_id}.
Show {limit} saved checkpoints from job {fine_tuning_job_id}.
GET /fine_tuning/jobs/{fine_tuning_job_id}/events Show progress events for a fine-tuning job · Get status updates for a fine-tuning job #
Ask an LLM
“What status updates has my fine-tuning job logged so far?”
“Where can I follow the training progress messages of a fine-tune?”
Tell an agent
Show the events for fine-tuning job {fine_tuning_job_id}.
Get the latest {limit} progress updates from fine-tune {fine_tuning_job_id}.
POST /fine_tuning/jobs/{fine_tuning_job_id}/pause Pause a running fine-tuning job · Pause a fine-tune job #
Ask an LLM
“Can I temporarily pause a fine-tuning job without cancelling it?”
“Is there a way to hold a fine-tune and pick it up later?”
Tell an agent
Pause fine-tuning job {fine_tuning_job_id}.
Put fine-tune {fine_tuning_job_id} on hold for now.
POST /fine_tuning/jobs/{fine_tuning_job_id}/resume Resume a paused fine-tuning job · Resume a fine-tune job #
Ask an LLM
“How do I restart a fine-tuning job I paused earlier?”
“Can a paused fine-tune continue training from where it stopped?”
Tell an agent
Resume fine-tuning job {fine_tuning_job_id}.
Continue the paused fine-tune {fine_tuning_job_id}.
