Release v1.6.0

Highlights

Experimental auto-differentiation helpers

This release adds a suite of experimental helpers that let you generate AD endpoints automatically — without implementing analytical derivatives. Two new families of functions are available in tesseract_core.runtime.experimental:

Finite differences (when you have no derivative implementation at all):

from tesseract_core.runtime.experimental import (
finite_difference_jacobian,
finite_difference_jvp,
finite_difference_vjp,
)

Gradient fallbacks (when you have one AD endpoint and want others to be derived from it):

from tesseract_core.runtime.experimental import (
jvp_from_jacobian,
vjp_from_jacobian,
jacobian_from_jvp,
jacobian_from_vjp,
)

For more information, see the linked examples and API reference.

Significant performance improvements

Two fixes combine to substantially reduce latency:

  • A fixed 100ms overhead per call has been eliminated (#485).
  • Array encoding/decoding is now much faster (#522) thanks to orjson, pybase64, zero-copy serialization, and HTTP session reuse.

Note: orjson and pybase64 are now core dependencies. If you pin dependencies or install from source, make sure to include them.

Other notable changes

  • CLI alias tesseract-core: You can use this instead of tesseract, for example to avoid collision with other command line tools called tesseract (#491).
  • json+binref encoding now works in the Python SDK, not just at the runtime level (#491).
  • Pass flags to docker run via --docker-run-args for custom container configuration (#491).
  • metadata field in tesseract_config.yaml: Attach arbitrary metadata to your Tesseract image as a Docker label (#523).
  • Custom validation errors no longer break tracebacks when triggered over HTTP (#534).

What’s Changed
