For a single agent, two words cover it — and they answer different questions:
|

For a single agent, pick the axis you need — remote **tools** or a remote **loop**:

||||
|
||||
```python
|
||||
from praisonaiagents import Agent
|
||||
from praisonai import Agent, LocalAgent, LocalAgentConfig, HostedAgent
|
||||
|
||||
# A. Only the TOOLS move. Thinking stays on your machine.

||||
# tenki | sandlock | ssh | novita | subprocess
|
||||
# A. Tools run in a remote sandbox; the agent loop stays local
|
||||
agent = Agent(name="builder", backend=LocalAgent(
|
||||
compute="e2b", # or modal | daytona | flyio | docker | tenki
|
||||
config=LocalAgentConfig(model="gpt-4o-mini", name="RemoteTools"),
|
||||
))
|
||||
|
||||
# B. The WHOLE agent moves — model calls, loop and tools
|
||||
agent = Agent(name="teacher", instructions="You teach.", run_on="anthropic") # hosted
|
||||
agent = Agent(name="builder", instructions="You build.", run_on="docker") # self-hosted
|
||||
# B. The entire agent loop runs in the cloud (needs ANTHROPIC_API_KEY)
|
||||
agent = Agent(name="teacher", backend=HostedAgent(provider="anthropic"))
|
||||
agent.start("Write a Python script that prints the first 10 primes, then run it")
|
||||
```
|
||||
|
||||
Ask any object where it runs, and it will tell you:
|
||||
|
||||
```python
|
||||
>>> Agent(name="builder", instructions="x", tools_run_on="docker")
|
||||
Agent(name='builder', thinks_on='this machine', tools_run_on='a Docker container')
|
||||
|
||||
>>> agent.where_does_it_run()
|
||||
Thinking (the AI model calls) happens on this machine.
|
||||
Tools run on a Docker container.
|
||||
Your own tools (check_db) still run on this machine -- only shell, file and
|
||||
code tools move. They read and write this machine's files.
|
||||
```
|
||||
|
||||
Naming a place that cannot do the job is a typo, not a preference, so it says so:
|
||||
|
||||
```python
|
||||
>>> Agent(name="x", instructions="i", run_on="e2b")
|
||||
TypeError: Agent(run_on='e2b') is not valid: run_on= places the whole agent
|
||||
-- model calls, loop and tools -- on a managed runtime, and 'e2b' runs
|
||||
commands but cannot host an agent loop.
|
||||
To run only the tools there: Agent(tools_run_on='e2b')
|
||||
```
|
||||
|
||||
To run one block of code somewhere else, name the place on that call:
|
||||
|
||||
```python
|
||||
agent.execute_code_sync("print(6 * 7)", run_in="sandlock") # kernel-enforced
|

```

"""One vocabulary for "where does this run?", shared by Agent, AgentFlow and AgentTeam.

|

Two questions get asked about placement and they have different answers:
|

|

``run_on=``
|
||||
Where the **whole agent** runs -- the model calls, the loop, the tools, all
|
||||
of it on someone else's machine. Only a *managed runtime* can answer this,
|

because running the loop remotely means something has to host the loop.
|
||||
|

``tools_run_on=``
|

Where **the tools** run. Thinking stays on this machine; only the shell,
|

the file writes and the code execution move. Any sandbox or compute place
|
||||
can answer this, because all it has to do is run a command.
|
||||
|
||||
Keeping the two words apart is the entire point. The old surface used one word
|
||||
(``run_on=``) on ``AgentFlow``/``AgentTeam`` for the tools-only meaning, another
|
||||
(``compute=``) on ``LocalAgent`` for exactly the same meaning, and a third
|
||||
(``backend=``) for the whole-agent meaning -- so the same concept had two names
|
||||
and one name had two concepts.
|
||||
|
||||
Because the two questions have disjoint answer sets, a wrong pairing is a typo
|
||||
worth catching rather than a preference worth honouring. ``run_on="docker"``
|

cannot mean anything: Docker does not host agent loops. It gets a ``TypeError``

``AgentFlow``/``AgentTeam`` already share one sandbox across a run and tear it
|

down when the run ends. A lone ``Agent(tools_run_on=...)`` has no "run" to hang
|
||||
that lifetime on -- it is just an object someone calls ``chat()`` on, possibly
|

many times -- so the sandbox is created on first use and lives as long as the

agent does. That is deliberate: a file written in turn 1 is still there in turn
|
||||
2, which is what anyone who asked for a working directory expects.
|
||||
|
||||
Attachment is idempotent and happens at the top of ``chat``/``achat``/
|
||||
``_start_stream``, and in ``AgentTeam`` before the task's tool list is

snapshotted. Doing it once, rather than wrapping each call in a context
|

manager, sidesteps two real hazards in this codebase:
|

|

* ``_start_stream`` is a **generator**; a context manager around the call would
|

exit before the caller consumed a single token, tearing down the sandbox while
|
||||
the model was still using it.
|
||||
* ``_start_stream`` falls back to ``self.chat``, so a wrapper would **re-enter**
|
||||
itself and provision a second sandbox.
|
||||
|
||||
Lifetime is tied to the agent by ``weakref.finalize`` rather than a process-exit
|
||||
hook over a weak set. The weak set leaked: an agent and its ``SharedCompute``
|
||||
reference each other, so a dropped agent was reclaimed by the cycle collector,

vanished from the set, and its sandbox was never shut down. Gateways clone an

## Context Caching
|
||||
|
||||
Prompt caching is opt-in via `caching=CachingConfig(prompt_caching=True)` — there
|

is no top-level `prompt_caching` parameter on `Agent`. When enabled, `Agent`
|
||||
checks `praisonaiagents.llm.model_capabilities.supports_prompt_caching(model)`

and, for providers that need explicit breakpoints (Anthropic), injects
|
||||
`cache_control` markers itself. OpenAI/Gemini use automatic prefix caching, so no
|
||||
markers are emitted:
|
||||
For cost optimization, use `prompt_caching=True` with Anthropic models:
|
||||
|
||||
```python
|
||||
from praisonaiagents import Agent, MemoryConfig, CachingConfig

||||

agent = Agent(

name="Assistant",
|

||||
prompt_caching=True, # Enables Anthropic prompt caching
|
||||
)
|
||||
```
|
||||
|
||||
This caches the system prompt, reducing token costs for repeated conversations.
|
||||
Without `prompt_caching=True`, no `cache_control` breakpoints are injected on the

Anthropic path.
