docs(examples): list MiniMax M3.1 Flash and M3 as harness_duo model options by octo-patch · Pull Request #1112 · Agent-Field/agentfield

octo-patch · 2026-10-19T14:59:56Z

Maintainer takeover (2026-10-30): re-checked OpenRouter: minimax-m3.1-flash:free currently has no published endpoint, while minimax-m3.1-flash has 12 providers and minimax-m2.7 still has 5 live ones with tool support. The example keeps minimax-m2.7 as its default; the README and provider guide list minimax-m3.1-flash and minimax-m3 as HARNESS_MODEL options and drop the dated availability notes. TestPiFamilyPreservesOpenRouterFreeSuffix stays. main merged in to clear the README conflict. The original description follows.

Reason: the active Pi/OMP Go workflow still defaults to MiniMax M2.7. MiniMax M3.1 Flash is now available through OpenRouter's :free route, while the bare Flash slug has no published endpoint.

Summary

Use openrouter/minimax/minimax-m3.1-flash:free as the harness_duo default and update its README and provider guide. Document the verified openrouter/minimax/minimax-m3 alternative, preserve HARNESS_MODEL and per-call overrides, and cover the :free suffix through both Go adapters.

The current Flash endpoint supports tools with automatic tool choice; the adapters do not force tool choice and structured output uses files. No direct MiniMax route, model-specific runtime capabilities, or price estimates are added.

Availability was checked on 2026-10-19:

https://openrouter.ai/api/v1/models/minimax/minimax-m3.1-flash/endpoints — no endpoints.
https://openrouter.ai/api/v1/models/minimax/minimax-m3.1-flash:free/endpoints — live Minimax endpoint; tools and automatic tool choice.
https://openrouter.ai/api/v1/models/minimax/minimax-m3/endpoints — live M3 alternatives.

Type of change

Test plan

cd examples/go_agent_nodes && go test ./cmd/harness_duo && go vet ./cmd/harness_duo.
cd sdk/go && go test ./harness -count=1, including TestPiFamilyPreservesOpenRouterFreeSuffix for Pi and OMP.
cd sdk/go && go test ./... and go mod tidy -diff passed.
Changed Go files formatted; git diff --check and diff secret scan.
./scripts/test-all.sh reported an unrelated control-plane failure in TestStopHTTPServerShutdownTimeout (graceful_shutdown_test.go:170: expected an error, got nil). Stopped the remaining run after recording that failure; Python/TypeScript/UI stages were not reached. This PR remains a draft pending broader validation and coverage CI.

No live inference or external agent CLI was run. The route remains subject to OpenRouter availability/free-route limits and the installed CLI's model catalog. The SDK's generic model passthrough and historical invalid-model cases are unchanged.

Test coverage

I ran tests for the surfaces I changed locally.
The route suffix is covered through adapter argument construction and normalized model metrics.
The coverage gate check is green in CI before requesting review. The completed Python coverage job reported 6 failed, 2,552 passed, 4 skipped and 38 deselected. All six failures are in unchanged Python tests and report FastAPI.__init__() got an unexpected keyword argument 'enable_mcp'; the event-loop message is an additional warning. The coverage summary subsequently failed because the Python coverage artifact was missing. Go, control-plane/Go/TypeScript/UI coverage, local/PostgreSQL functional tests, and the main build passed. No Python files changed. Both affected test modules were independently rerun on the unmodified base 2f5583e5d88f27c1175e58978a4464463553b38d in an isolated Python 3.11 environment with the declared dev dependencies: the same six failures reproduced, with 20 tests passing.

One concern before this comes out of draft: openrouter/minimax/minimax-m2.7 still has six live providers on OpenRouter (GMICloud, Novita, AtlasCloud, Minimax, Groq), while minimax-m3.1-flash:free has exactly one, the Minimax free endpoint, and the bare Flash slug has none. Switching the example's default to a single free route makes harness_duo less reliable for people who copy it: free routes are rate-limited, can disappear without notice, and the dated "as of 2026-10-19" notes will go stale.

I'd keep m2.7 as the default (or move to minimax-m3, which has 14 providers) and mention the Flash :free route as an option you can set through HARNESS_MODEL. The new TestPiFamilyPreservesOpenRouterFreeSuffix is worth keeping either way. The red coverage (sdk-python) check was the FastAPI 0.148 test break that #1120 fixed on main; merging main will clear it.

# Conflicts: # examples/go_agent_nodes/cmd/harness_duo/README.md

M2.7 still has several live OpenRouter providers, while the minimax-m3.1-flash:free route currently has no published endpoint. List M3.1 Flash and M3 as HARNESS_MODEL options instead of making a single free route the default, and drop the dated availability notes. The :free suffix pass-through test stays.

Took this over since it had been sitting for a while. I re-checked OpenRouter today and the picture flipped: minimax-m3.1-flash:free has no published endpoints right now, while the bare minimax-m3.1-flash has a dozen providers and minimax-m2.7 still has five live ones with tool support. So the example keeps minimax-m2.7 as its default, the README and provider guide list M3.1 Flash and M3 as HARNESS_MODEL options, and the dated availability notes are gone. Your TestPiFamilyPreservesOpenRouterFreeSuffix test stays, since passing :free through untouched is worth guarding. I also merged main to clear the conflict (main renamed the default harness to codeaf).

Net change against main is now the two doc updates plus the :free suffix test. The example default is unchanged. Harness tests pass and CI is green.
