Local LLM ran out of VRAM or context during a coding task

Local models are powerful, private, and cheap, but they hit practical limits: VRAM, context length, and weaker reasoning on messy state.

Short version: Local-first should not mean fragile.

Why this hurts.

When a local agent fails, the next model still needs the current repo state, not a half-remembered chat.

How ShardStitch solves it.

01 / ShardStitch

Preserve the project checkpoint

Save the diff, active goal, failed attempt, and next check before retrying with a smaller context.

02 / ShardStitch

Record the runtime conditions

Record the model, context setting, available VRAM, and exact out-of-memory or context error.

03 / ShardStitch

Reduce the next unit of work

Split the next action into a smaller testable step; use a larger model only when configured and needed.

04 / ShardStitch

Retry only after checking resources

Check free memory and settings before retrying; if the local model still fails, carry the packet to a configured alternative.

What the next AI receives.

  • Small context packet
  • Current files

What stays out.

  • Irrelevant files
  • Large blobs unless needed

Separate model pressure from lost work

Stop repeated retries and check whether the repository changes were saved. Record the failing command and exact error before changing model settings.
Note the model, quantization, context setting, GPU/runtime, and input size if known. These conditions help distinguish memory pressure from an unrelated crash.
Try a smaller prompt or task slice and adjust the local runtime using its own documented controls. ShardStitch does not allocate VRAM or guarantee a model will fit.
Resume from verified project state. If the same resource failure repeats, keep the output and change one runtime variable at a time rather than rerunning the whole coding task.

FAQ.

Can ShardStitch fix a local model VRAM error?

No. It can help carry project context into a smaller or later run, but GPU memory allocation is controlled by the model runtime and hardware.

Will a shorter handoff guarantee the model fits?

No. Memory use also depends on model size, runtime, context configuration, and other processes. A smaller task may help, but verify it in the local runtime.
