Conversation
Adds claude-opus-4-8 to the llm-gateway Bedrock mapping and product allowlists (posthog_code, background_agents), and to the AI observability supported models list. Updates default model references from opus-4-7 to opus-4-8 for the sandbox eval agent, custom prompt docstring, and personal-spend test fixtures.

Problem
Anthropic released claude-opus-4-8. The llm-gateway needs to allow the new
model id (with the corresponding Bedrock inference profile mapping), and
the places that previously defaulted to opus-4-7 should point at the
newer flagship.
Changes
services/llm-gateway/src/llm_gateway/bedrock.py— add the US/EUclaude-opus-4-8Bedrock inference-profile mapping.services/llm-gateway/src/llm_gateway/products/config.py— allowclaude-opus-4-8forposthog_code(shared withslack_app) andbackground_agents.services/llm-gateway/tests/test_bedrock.py,services/llm-gateway/tests/test_product_config.py— extend theparametrized cases to cover opus-4-8.
products/ai_observability/backend/llm/providers/anthropic.py—list opus-4-8 first in
SUPPORTED_MODELS,SUPPORTED_MODELS_WITH_CACHE_CONTROL, andSUPPORTED_MODELS_WITH_THINKING.products/tasks/backend/temporal/process_task/utils.py— addreasoning-effort tuple for opus-4-8 (same shape as opus-4-7).
ee/hogai/eval/conftest.py— default--agent-modelis nowanthropic/claude-opus-4-8.products/tasks/backend/services/custom_prompt_internals.py—docstring example uses opus-4-8.
products/ai_observability/backend/api/test/test_personal_spend.py—test fixture default model bumped to opus-4-8.
How did you test this code?
Agent-authored. No manual testing performed. The change is mechanical:
adding a model id to allowlists/mappings and swapping a few default
values. Existing parametrized tests in
test_bedrock.pyandtest_product_config.pywere extended to exercise the new id; CI willrun them.

🤖 Agent context
Authored by PostHog Code. The task was to add opus-4-8 to the ai
gateway and swap defaults from opus-4-7. Opus-4-7 entries were kept
alongside the new id (not replaced) because 4.7 is still a supported
model — the change only adds 4.8 to allowlists and promotes it to the
default where opus-4-7 was previously the default. The auto-generated
nodejs/src/ingestion/ai/costs/providers/llm-costs.jsonwas left tothe scheduled cost-update workflow; the opus-4-7 references in
ee/hogai/test/eval/test_acp_log_model.pyare log-parsing fixtures(not defaults) and were left as-is.
