Deep Agents Code now automatically detects the provider for additional bare model names supported by its provider extras — Cohere Command, Mistral AI, DeepSeek, xAI Grok, and Perplexity Sonar — and recognizes Amazon Bedrock model IDs by their vendor-namespaced structure, including versioned and cross-region inference-profile IDs.

Deep Agents Code resolves a model provider before calling init_chat_model so it can apply provider-specific configuration and report credential errors clearly. Its local inference table did not recognize several bare model names that LangChain already supports, even though the corresponding dcode provider extras are available.

For the direct-API providers, mirror LangChain's supported prefix mappings: OpenAI text-davinci*, Cohere command*, Mistral AI mistral*/mixtral*, DeepSeek deepseek*, xAI grok*, and Perplexity sonar*.

Bedrock is handled structurally rather than by an enumerated prefix list: any [<region>.]<vendor>.<model> ID (e.g. meta.llama3-70b-instruct-v1:0, mistral.mistral-large-2402-v1:0, or the cross-region profile us.anthropic.claude-3-5-sonnet-20241022-v2:0) is detected as Bedrock. Keying off the dotted vendor-namespace signature avoids maintaining AWS's ever-growing vendor list while keeping bare direct-API names (mistral-large, command-r-plus) routed to their own APIs.

Because Bedrock IDs can carry a :<version> suffix, create_model now treats a detected Bedrock spec as a bare model name so the suffix is not misparsed as a provider:model separator. An explicit provider:model spec whose provider is configured still takes precedence.

Existing dcode-specific handling for o4*, NVIDIA, credential-aware Claude and Gemini routing, and fully qualified Fireworks model IDs remains unchanged. solar* remains unrecognized because dcode does not yet package or configure Upstage.

fix(code): infer additional model providers (langchain-ai#4675)
58de1d4 
Deep Agents Code now automatically detects the provider for additional
bare model names supported by its provider extras — Cohere Command,
Mistral AI, DeepSeek, xAI Grok, and Perplexity Sonar — and recognizes
Amazon Bedrock model IDs by their vendor-namespaced structure, including
versioned and cross-region inference-profile IDs.

---

Deep Agents Code resolves a model provider before calling
`init_chat_model` so it can apply provider-specific configuration and
report credential errors clearly. Its local inference table did not
recognize several bare model names that LangChain already supports, even
though the corresponding dcode provider extras are available.

For the direct-API providers, mirror LangChain's supported prefix
mappings: OpenAI `text-davinci*`, Cohere `command*`, Mistral AI
`mistral*`/`mixtral*`, DeepSeek `deepseek*`, xAI `grok*`, and Perplexity
`sonar*`.

Bedrock is handled structurally rather than by an enumerated prefix
list: any `[<region>.]<vendor>.<model>` ID (e.g.
`meta.llama3-70b-instruct-v1:0`, `mistral.mistral-large-2402-v1:0`, or
the cross-region profile `us.anthropic.claude-3-5-sonnet-20241022-v2:0`)
is detected as Bedrock. Keying off the dotted vendor-namespace signature
avoids maintaining AWS's ever-growing vendor list while keeping bare
direct-API names (`mistral-large`, `command-r-plus`) routed to their own
APIs.

Because Bedrock IDs can carry a `:<version>` suffix, `create_model` now
treats a detected Bedrock spec as a bare model name so the suffix is not
misparsed as a `provider:model` separator. An explicit `provider:model`
spec whose provider is configured still takes precedence.

Existing dcode-specific handling for `o4*`, NVIDIA, credential-aware
Claude and Gemini routing, and fully qualified Fireworks model IDs
remains unchanged. `solar*` remains unrecognized because dcode does not
yet package or configure Upstage.
