run_codeflash

✓ import codeflash

✗ from codeflash import run_codeflash

Initialize Codeflash with API key and optimize a function.

from codeflash import run_codeflash # Example: optimize a simple function def slow_function(n: int) -> int: total = 0 for i in range(n): total += i return total # Run codeflash optimization (requires CODEFLASH_API_KEY env var) optimized_code = run_codeflash(slow_function, api_key=os.environ.get('CODEFLASH_API_KEY', '')) print(optimized_code)

codeflash --version

Debug

Known issues

breakingIn v0.17.0, the API changed from `codeflash.optimize` to `codeflash.run_codeflash`. Old code using `import codeflash.optimize` will break.

fix

Update imports to `from codeflash import run_codeflash`.

affects: <0.17.0

gotchaCodeflash requires an API key set via `CODEFLASH_API_KEY` environment variable. Without it, `run_codeflash` raises an authentication error.

fix

Set `CODEFLASH_API_KEY` in your environment or pass `api_key` parameter.

affects: all

deprecatedThe `verbose` parameter in `run_codeflash` is deprecated since v0.19.0 and will be removed in v0.21.0. Use `logging` level instead.

fix

Remove `verbose` parameter and configure Python logging: `logging.basicConfig(level=logging.INFO)`.

affects: >=0.19.0, <0.21.0

gotchaCodeflash only supports Python 3.9 and above. Installing on older Python versions will fail with a `Requires-Python` error.

fix

Ensure Python >=3.9 is used.
